As another example, through an online video playback application, different users may send bullet screen information at a video playback interface, and so on. When sending information such as characters, the electronic equipment can add background special effects such as bubbles to the characters, so that the sent characters have more interesting bubbles.
In general, bubbles in text bubbles are generated from an image (e.g., a picture) that can be subjected to a stretching process. However, in the related art, in order to obtain a picture that can be used as a bubble, the electronic apparatus needs to perform a cumbersome processing operation on the picture.

For example, after acquiring the pixel information of the first image, the electronic device may set the stretchable region and the content-filled region on the first image according to the pixel information of the first image. The stretchable region is used for stretching the image, namely, stretching the image can be realized by stretching the stretchable region on the image. The content filling area is used for filling information on the image, namely, the electronic device can fill and add other information on the image through the content filling area, for example, the electronic device can add other characters or pictures in the content filling area of the image.

For example, after the stretchable region and the content-filled region are set on the first image, the electronic device may convert the first image provided with the stretchable region and the content-filled region into a second image of a preset object type. For example, the electronic device may convert the first image provided with the stretchable region and the content filling region into an image of the ninePatchDrawable object, that is, obtain a second image, so that the electronic device may parse the stretchable region and the content filling region on the image after obtaining the second image. That is, after the electronic device acquires the second image of the preset object type, it can analyze which areas on the image are stretchable areas and which areas belong to the content filling area.
It can be understood that in the embodiment of the present application, the electronic device may set the stretchable region and the content filling region for the first image according to the pixel information of the first image, and convert the stretchable region and the content filling region into the second image of the preset object type, so that the electronic device can identify the stretchable region and the content filling region on the second image. That is, the present application can quickly obtain an image having a stretchable region and a content-filled region, and an image having a stretchable region and a content-filled region can be used as bubbles in a text bubble, so that the embodiment of the present application can quickly obtain an image that can be used as bubbles in a text bubble.
Referring to fig. 2, fig. 2 is another flow chart of the image processing method according to the embodiment of the application, and the flow may include:
201. a first image is acquired.
For example, the electronic device may first acquire the first image.
202. Pixel information of a first image is acquired.
For example, after acquiring the first image, the electronic device may acquire pixel information of the first image.
In some embodiments, the pixel information may include information such as the number of pixel rows, the number of pixel columns, the pixel value of each pixel, the color, and so on, which is specifically limited by the embodiment of the present application.
203. And setting a stretchable region and a content filling region on the first image according to the pixel information of the first image, wherein the stretchable region is used for realizing stretching treatment on the image, the content filling region is used for realizing filling information on the image, and the stretchable region and the content filling region have overlapping parts.
For example, after acquiring the pixel information of the first image, the electronic device may set the stretchable region and the content-filled region on the first image according to the pixel information of the first image. The stretchable region is used for stretching the image, namely, stretching the image can be realized by stretching the stretchable region on the image. The content filling area is used for filling information on the image, namely, the electronic device can fill and add other information on the image through the content filling area, for example, the electronic device can add other characters or pictures in the content filling area of the image.
The stretchable region and the content filling region have overlapping parts, so that the content filling region can be synchronously stretched when the stretchable region is stretched, and further more graphic information can be filled in the stretched content filling region.
204. And converting the first image provided with the stretchable region and the content filling region into a second image of a preset object type, so that the electronic equipment can analyze the stretchable region and the content filling region on the image after acquiring the second image.
For example, after the stretchable region and the content-filled region are set on the first image, the electronic device may convert the first image provided with the stretchable region and the content-filled region into a second image of a preset object type. For example, the electronic device may convert the first image provided with the stretchable region and the content filling region into an image of the ninePatchDrawable object, that is, obtain a second image, so that the electronic device may parse the stretchable region and the content filling region on the image after obtaining the second image. That is, after the electronic device acquires the second image of the preset object type, it can analyze which areas on the image are stretchable areas and which areas belong to the content filling area.
For example, as shown in fig. 3, a stretchable region (i.e., a gray region) and a content-filled region (i.e., a gray region) provided on a first image are shown in fig. 3, and after converting the first image into a second image of a preset object type, the stretchable region and the content-filled region on the first image become the stretchable region and the content-filled region on the second image. In the figures, the stretchable region may be the same region as the content-filled region.
205. And acquiring information to be displayed.
For example, after the second image is acquired, the electronic device may also acquire information to be displayed.
In some embodiments, the information to be displayed may be text information or picture information, which is not limited in detail in the embodiments of the present application.
206. And determining the stretching parameter of the second image according to a first area and a second area, wherein the first area is the display area required by the information to be displayed, and the second area is the area of the content filling area of the second image.
For example, after acquiring the information to be displayed, the electronic device may determine the stretching parameter of the second image according to the first area and the second area. The first area is a display area required by information to be displayed. For example, the information to be displayed is a text, and the electronic device may determine the first area according to the font type, the font size, the display area required by each text under the font type and the font size, and the number of words. The second area is the area that the content-filled region of the second image had before being stretched.
207. And stretching the stretchable region on the second image according to the stretching parameters to obtain a third image, wherein the content filling region of the second image is synchronously stretched and becomes the content filling region of the third image in the process of stretching the second image.
For example, after determining the stretching parameter, the electronic device may stretch the stretchable region on the second image according to the stretching parameter, so as to obtain a stretched image, that is, a third image. In the stretching process of the stretchable region of the second image, since there is an overlapping portion between the stretchable region and the content filling region of the second image, the content filling region of the second image is stretched synchronously with the stretching of the stretchable region, and becomes the content filling region of the third image.
For example, as shown in fig. 4, the electronic device performs stretching processing on the stretchable region on the second image according to the stretching parameters, thereby obtaining a third image. As can be seen from the figure, the area of the content-filled region of the third image is enlarged, i.e., stretched, compared to the content-filled region of the second image.
208. And filling the information to be displayed into the content filling area of the third image to obtain a fourth image.
For example, after obtaining the third image, the electronic device may fill information to be displayed into a content filling area of the third image, thereby obtaining a fourth image. It is understood that the fourth image is a text bubble with a background effect.
For example, the information to be displayed is "the television play is very good, the performance of the actor is very line, the line of the line is very deep, the scene is well designed, all is perfect, and is worth recommending you at one glance", the electronic device can fill the text information to be displayed into the content filling area of the third image, so as to obtain a fourth image, and as shown in fig. 5, the fourth image is a text bubble. After the text bubble corresponding to the fourth image is obtained, the electronic device can send the text bubble out.
In one embodiment, the stretchable region on the second image may comprise a laterally stretchable region. As shown in fig. 6, the gray areas in fig. 6 are the lateral stretching areas. The lateral stretching regions may be used to effect a stretching process of the image in the lateral direction. The stretch parameter may include a stretch factor, which may be an integer. For example, the stretching ratio is 1-fold or 2-fold or 3-fold, etc.
Then, the process of stretching the stretchable region on the second image by the electronic device may include: the electronic device inserts a target number of pixels, which is a value corresponding to the stretching multiple, into the laterally adjacent positions of the pixels for each pixel in the laterally stretchable region on the second image.
For example, in the case where the second image has a laterally stretchable region thereon, the stretching process performed by the electronic device on the second image may be a stretching process performed on the laterally stretchable region. When stretching the laterally stretchable region, for each pixel in the laterally stretchable region, the electronic device may insert a target number of pixels at laterally adjacent positions of the pixel, the target number being a value corresponding to the stretch ratio.
For example, the stretching ratio is 1 time. Then, for each pixel within the laterally stretchable region, the electronics can insert 1 pixel in a laterally adjacent location of that pixel. For example, as shown in fig. 7, the laterally stretchable region of the second image is a region having 4 pixels in the lateral direction and 3 pixels in the longitudinal direction (i.e., a region of 3 rows of pixels by 4 columns of pixels). Then, for each pixel within the laterally stretchable region, the electronic device may insert 1 pixel in its laterally adjacent position such that the laterally stretchable region is stretched from a region of 3 rows of pixels by 4 columns of pixels to a region of 3 rows of pixels by 8 columns of pixels, as shown in fig. 7. In other words, the stretching treatment performed on the laterally stretchable region corresponds to inserting pixel columns for the laterally stretchable region.
Of course, for convenience of explanation in this embodiment, the stretchable region is exemplified to include 3 rows and 4 columns of pixels. In practice, the number of rows of pixels in the stretchable region on the image is much greater than 3 rows and the number of columns of pixels is much greater than 4 columns.
In another embodiment, the stretchable region on the second image may comprise a longitudinal stretchable region. As shown in fig. 8, the gray areas in fig. 8 are longitudinally stretched areas. The longitudinal stretching region may be used to achieve a stretching process of the image in the longitudinal direction. The stretch parameters include stretch factors, which may be integers. For example, the stretching ratio is 1-fold or 2-fold or 3-fold, etc.
Then, the process of stretching the stretchable region on the second image by the electronic device may include: the electronic device inserts a target number of pixels, which is a value corresponding to the stretching multiple, into the longitudinally adjacent positions of the pixels for each pixel in the longitudinally stretchable region on the image.
For example, in the case where the second image has a longitudinally stretchable region thereon, the stretching process performed by the electronic device on the second image may be a stretching process performed on the longitudinally stretchable region. When stretching is performed on the longitudinally stretchable region, for each pixel in the longitudinally stretchable region, the electronic device may insert a target number of pixels at longitudinally adjacent positions of the pixel, the target number being a value corresponding to the stretch multiple.
For example, the stretching ratio is 1 time. Then, for each pixel within the longitudinally stretchable region, the electronic device may insert 1 pixel at a longitudinally adjacent location of that pixel. For example, as shown in fig. 9, the longitudinally stretchable region of the second image is a region having 4 pixels in the longitudinal direction and 3 pixels in the transverse direction (i.e., a region of 4 rows of pixels by 3 columns of pixels). Then, for each pixel within the longitudinally stretchable region, the electronic device may insert 1 pixel at its longitudinally adjacent location, such that the longitudinally stretchable region is stretched from a region of 4 rows of pixels by 3 columns of pixels to a region of 8 rows of pixels by 3 columns of pixels, as shown in fig. 9. In other words, the stretching treatment performed on the longitudinally stretchable region corresponds to inserting pixel rows for the longitudinally stretchable region.
Of course, for convenience of explanation in this embodiment, the stretchable region includes 4 rows and 3 columns of pixels as an example. In practice, the number of rows of pixels in the stretchable region on the image is much greater than 4 rows and the number of columns of pixels is much greater than 3 columns.
In yet another embodiment, the stretchable region on the second image may comprise both a laterally stretchable region and a longitudinally stretchable region. As shown in fig. 10, the gray area in fig. 10 is an area that can be stretched in both the transverse direction and the longitudinal direction. The stretch parameter may include a stretch factor, which may be an integer. For example, a stretch ratio of 3, etc.
Then, the process of stretching the stretchable region on the second image by the electronic device may include: the electronic equipment inserts a first number of pixels at the lateral adjacent positions of the pixels for each pixel in the lateral stretchable region on the two images; inserting a second number of pixels at longitudinally adjacent locations of the pixels for each pixel within the longitudinally stretchable region on the second image; after the pixel insertion is completed, the ratio of the number of pixels inserted into the content filling area of the second image to the number of original pixels of the content filling area of the second image is a value corresponding to the stretching multiple.
For example, the stretching ratio is 3 times. Then the electronic device may stretch the stretchable zone 1-fold in the lateral direction and 1-fold in the longitudinal direction. For example, for each pixel within a stretchable region, the electronics can insert 1 pixel in a laterally adjacent location of that pixel. Thereafter, for each pixel within the stretchable region, the electronics can insert 1 pixel in a longitudinally adjacent location of that pixel. For example, as shown in fig. 11, the stretchable region of the second image is a region having 3 pixels in the longitudinal direction and 3 pixels in the transverse direction (i.e., a region of 3 rows of pixels by 3 columns of pixels). Then, for each pixel in the stretchable region, the electronic device may first insert 1 pixel in a laterally adjacent position of the pixel, such that the stretchable region is stretched from a region of 3 rows of pixels by 3 columns of pixels to a region of 3 rows of pixels by 6 columns of pixels. Then, for each pixel in the 3-row-by-6-column pixel region, the electronic device may insert 1 pixel at its vertically adjacent position, so that the stretchable region is stretched from the 3-row-by-6-column pixel region to the 6-row-by-6-column pixel region, as shown in fig. 11. In other words, the stretching treatment performed on the stretchable region corresponds to inserting pixel rows and pixel columns for the stretchable region. After the pixel insertion in the lateral direction and the longitudinal direction is completed, 27 pixels are inserted in total. The ratio of the newly inserted 27 pixels to the original 9 pixels is 3, and the ratio is equal to the value of 3 times of the stretching multiple.
Of course, for convenience of explanation in this embodiment, the stretchable region includes 3 rows and 3 columns of pixels. In practice, the number of rows of pixels in the stretchable region on the image is much greater than 3 rows and the number of columns of pixels is much greater than 3 columns.
In the embodiment of the application, when the pixel is required to be inserted at the adjacent position of the pixel, the newly inserted pixel can keep the same color with the original pixel. For example, a certain line in an image includes 3 pixels, and the colors of the 3 pixels are red, yellow, and blue in order. Then, the pixel inserted in the adjacent position of the red pixel may also be the red pixel. The pixels inserted in the adjacent positions of the yellow-colored pixels may be pixels of yellow color. The pixel inserted in the adjacent position of the blue pixel may be a blue pixel. That is, the color of the stretched pixel of this row is thus red, yellow, blue. When stretched longitudinally, the newly inserted pixel at a position adjacent to the original pixel may also remain the same color as the original pixel.
In the embodiment of the application, the electronic device can set the stretchable region and the content filling region on the first image in the following manner:
performing image segmentation processing on the first image;
Determining a target area in the first image according to an image segmentation result, wherein the target area is an area which does not contain an object image, and the number of pixel rows of the target area is equal to that of the first image;
and acquiring pixel information of a target area, and setting a stretchable area and a content filling area on the target area according to the pixel information of the target area.
For example, as shown in fig. 12, when the picture is used to generate bubbles that can be used as text bubbles, if the picture is stretched, the images of the objects will be deformed, thereby affecting the aesthetic appearance of the bubbles that are eventually generated. Thus, the image of these objects does not need to be stretched.
For this reason, after the first image is acquired, the electronic device may perform image division processing on the first image first. It will be appreciated that through the image segmentation process, the electronic device may identify the region of the first image containing the image of the object. The electronic device may determine, according to the image segmentation result, a target area on the first image, where the target area may be an area on the first image that does not include the object image, and a number of pixels of the target area is equal to a number of pixels of the first image. For example, as shown in fig. 13, the electronic device may determine a rectangular gray area in the drawing as a target area.
After determining the target area, the electronic device may acquire pixel information of the target area, and set a stretchable area and a content filling area on the target area according to the pixel information of the target area. Thereafter, the electronic device may determine the stretchable and content-filled regions of the target region as the stretchable and content-filled regions of the first image.
In one embodiment, the target area may be a rectangular area. Of course, in other embodiments, the target area may be an area of other shapes, such as a circle.
In the embodiment of the application, the electronic device may set the stretchable region in the target region by:
acquiring pixel information of a target area, wherein the pixel information comprises pixel column numbers and pixel row numbers;
according to the pixel column number and the pixel line number of the target area, a transverse stretchable area is arranged on the target area, the transverse stretchable area is a middle area in the transverse direction of the target area, the pixel column number contained in the transverse stretchable area is a preset third number, and the pixel line number contained in the transverse stretchable area is equal to the pixel line number of the target area.
For example, as shown in fig. 14, the target area is a rectangular area including 10 rows of pixels and 10 columns of pixels. The third number is preset to be 4. Then, the electronic device may set a laterally stretchable region on the target region, which is a middle region containing 4 columns of pixels and 10 rows of pixels in a lateral direction of the target region.
In the embodiment of the present application, the electronic device may further set the stretchable region in the target region by:
acquiring pixel information of a target area, wherein the pixel information comprises pixel column numbers and pixel row numbers;
according to the pixel column number and the pixel line number of the target area, a longitudinal stretchable area is arranged on the target area, the longitudinal stretchable area is a middle area in the longitudinal direction of the target area, the line number of the pixels contained in the longitudinal stretchable area is a preset fourth number, and the pixel column number contained in the longitudinal stretchable area is equal to the pixel column number contained in the target area.
For example, as shown in fig. 15, the target area is a rectangular area including 10 rows of pixels and 10 columns of pixels. The fourth number is preset to be 6. Then, the electronic device may set a longitudinally stretchable region on the target region, the longitudinally stretchable region being a middle region containing 6 rows of pixels and 10 columns of pixels in a longitudinal direction of the target region.
In one embodiment, the content-filled region on the first image may be located within the stretchable region. For example, the content-filled region may be a stretchable region. Alternatively, the content fill area may be a sub-area of smaller area within the stretchable region, and so on.
In the related art, taking an Android (Android) operating system as an example, a point nine technology may be used to process an image so as to obtain an image having a stretchable region and a content filling region that can be recognized by the Android system. However, in the related art, when the image is processed using the point nine technique, the operation steps are complicated. For example, a designer needs to input an image to be processed into a point nine-drawing production tool, and manually set a stretchable region and a content-filled region of the image in the point nine-drawing production tool. And many steps are required to complete this setup process.
The image processing method provided by the embodiment of the application can set the stretchable region and the content filling region for the first image according to the pixel information of the first image, and convert the stretchable region and the content filling region into the second image with the preset object type, so that the electronic equipment can identify the stretchable region and the content filling region on the second image. That is, the present application can quickly obtain an image having a stretchable region and a content-filled region, and an image having a stretchable region and a content-filled region can be used as bubbles in a text bubble, so that the embodiment of the present application can quickly obtain an image that can be used as bubbles in a text bubble.
In addition, since the embodiment of the application sets the stretchable region and the content filling region according to the pixel information (such as the pixel line number and the pixel column number) of the image, the embodiment of the application can accurately set the stretching part on the image to the pixel point.
In addition, as the pixels with the same color can be inserted in adjacent positions of the pixels when the image is stretched, the stretched image can be more coordinated and the visual effect is better.
Referring to fig. 16 to 17, fig. 16 to 17 are schematic views of an image processing method according to an embodiment of the application.
For example, through an instant messaging application, the user is currently chatting with friends, and as shown in fig. 16, the text that the user wants to send out has a special effect of bubbles, and the bubbles are generated by a certain picture a specified by the user. The user may first input the picture a to the electronic device. After the picture a is acquired, the electronic device may set a stretchable region and a content filling region on the picture a by using the image processing method provided by the embodiment of the present application. Then, the electronic device may convert the picture a provided with the stretchable region and the content filling region into a picture of the ninePatchDrawable object, for example, obtain a picture B, so that the electronic device may parse the stretchable region and the content filling region of the picture B after obtaining the picture B.
The electronic device may then obtain information (i.e., information to be displayed) that the user needs to send to the friend, e.g., a piece of text information. For example, the display area required for the electronic device to detect the text information is larger than the area of the content filling area of the picture B. In this case, the electronic device may determine the stretch factor of the picture B according to the display area required for the text information and the area of the content-filled region of the picture B. For example, the electronic device determines that the stretch factor of picture B is 1.
Then, the electronic device may perform stretching treatment for the stretchable region on the picture B by 1 time, thereby obtaining the picture C. It will be appreciated that the area of the content-filled region of picture C is also enlarged by a factor of 1 compared to picture B. Then, the electronic device may fill the text that the user needs to send to the friend into the content filling area of the image C, thereby obtaining a text bubble, and send the text bubble to the friend, as shown in fig. 19.
