Detailed Description
Exemplary embodiments of the present invention will be described in more detail below with reference to the accompanying drawings. While exemplary embodiments of the invention are shown in the drawings, it should be understood that the invention can be embodied in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the invention to those skilled in the art.
Example one
Fig. 1 is a flowchart illustrating a method for processing notes according to an embodiment of the present invention.
The note processing method provided by the embodiment of the invention is executed by the note processing device provided by the embodiment of the invention, the note processing device can be realized in a software or hardware mode, and the note processing device can be integrated in an ink screen reader.
As shown in fig. 1, the method includes:
and step S110, responding to a note erasing operation generated by the current page read by the ink screen reader, and acquiring a note erasing track generated along with the note erasing operation.
The note is a mark or a label added when the ink screen reader is used for reading, for example, the ink screen reader may be a reader with an electromagnetic plate or an electromagnetic pen. And a user carries out handwritten notes on corresponding characters of a reading page of the ink screen reader through an electromagnetic plate or an electromagnetic pen. The note content includes underlining, circling, writing text annotations, writing reading feelings of the user to the text, and pictures expressing the mood of the user.
The reading page may be a display interface of an electronic book (e.g., a novel, a prose, etc.), and the content of the electronic book is displayed through the display interface.
For example, an erasing button is arranged at a certain position of the ink screen reader or the current reading page, a user clicks the erasing button to enter a note erasing mode, an operation generated on a display screen of the ink screen reader by using the electromagnetic pen or the finger is recognized as a note erasing operation, and a note erasing track is generated on the current reading page following the note erasing operation.
Step S120, according to the note erasing track and the report point data of the existing note track, the report point data to be eliminated in the existing note track is determined, and the report point data to be eliminated in the existing note track is eliminated.
Specifically, when a note erasing track is generated following a note erasing operation, the hit data of the note erasing track is saved. Wherein, the punctuation data of the note erasure track includes coordinate information, line information (e.g., line color and/or line width). Similarly, the user may also save the report data of the note track (for example, in the local database or the remote server database) when writing the note, and obtain the report data of the existing note track when the note erasing operation is generated, where the report data of the existing note track includes at least one of coordinate information, line information (for example, line color and/or line width), note type (for example, pen, pencil, etc.), and a corresponding relationship between the start point coordinate and the end point coordinate and the offset of the preset text.
The preset characters may be characters within a preset range of the starting point coordinates and the ending point coordinates of the existing note track, for example, characters right above, or right below, or left above, or left below, or right above the starting point coordinates and the ending point coordinates. When the page mode of the current reading page changes (for example, the font size, the line spacing, and the like change), in order to redraw the existing note track in the changed reading page, a corresponding relationship between the start point coordinate and the end point coordinate and the offset of the preset text needs to be established, where the offset of the preset text is the display position or the text sequence of the text recorded in the source file on the reading page, for example, the 100 th word of the paragraph where the text is located, and the corresponding offset is always the 100 th word of the paragraph where the text is located no matter how the page mode changes, and cannot be changed along with the change.
Specifically, the note erasing operation is based on the existing note track, so that there may be a part where the newspaper point data of the note erasing track generated by the note erasing operation and the newspaper point data of the existing note track are overlapped, the newspaper point data of the overlapped part is determined as newspaper point data to be cleared in the existing note track, and further, the newspaper point data to be cleared in the existing note track is cleared.
And step S130, redrawing the existing note track according to the removed report point data of the existing note track.
Specifically, through the above step of clearing the point data, the cleared point data of the existing note track may be divided into point data of a plurality of note tracks. In the step, the existing note track can be directly redrawn according to the cleared report point data of the existing note track after the erasing operation is finished. Or when the user turns the page, or refreshes or restarts the current reading page, responding to the page turning operation, or refreshing operation or restarting operation of the current reading page, and redrawing the existing note track on the current reading page according to the cleared report point data of the existing note track.
Specifically, during drawing, firstly, a note layer is generated according to the cleared report point data of the existing note track, the note layer is synthesized with a page layer of the current reading page, the synthesized page is sent to a display cache, and the synthesized page is synchronized to an ink screen reader for displaying. Because the removed report point data of the existing note track does not contain the erased report point data, the existing note track redrawn according to the removed report point data of the existing note track is the erased note track, and the erasing effect can be displayed in real time.
Therefore, according to the embodiment, firstly, the newspaper point data to be cleared in the existing note track is determined according to the note erasing track and the newspaper point data of the existing note track, the newspaper point data to be cleared in the existing note track is cleared, then, the existing note track is redrawn according to the cleared newspaper point data of the existing note track, the erasing effect can be displayed in real time, and when the font, the font size, the line spacing and the like in the current reading page are changed, the existing note track is redrawn according to the cleared newspaper point data of the existing note track during redisplay, and normal reappearance can still be achieved.
Example two
Fig. 2 is a flow chart illustrating a note processing method according to the second embodiment of the present invention.
The embodiment is further optimized on the basis of the embodiment. As shown in fig. 2, the method includes:
step S210, responding to a note erasing operation generated by the current page read by the ink screen reader, and acquiring a note erasing track generated along with the note erasing operation.
Step S220, according to the report data of the note erasing track, directly drawing the note erasing track in a display cache and synchronizing the note erasing track to the current reading page of the ink screen reader for displaying; the point reporting data of the note erasing track comprises coordinate information and line width information of all track points of the note erasing track.
Specifically, in this step, according to the point reporting data of the note erasing track, that is, the coordinate information and the line width information of each track point, the note erasing track, that is, the erasing process, is drawn in the display cache, and is displayed on the current reading page, that is, the note erasing track is displayed on the current reading page in real time, and the erasing process is directly presented to the user.
Step S230, determining the report data to be cleared in the existing note track according to the note erasing track and the report data of the existing note track, and clearing the report data to be cleared in the existing note track.
And step S240, redrawing the existing note track according to the removed report point data of the existing note track.
Therefore, the erasing is firstly performed on the display, namely the erasing process is displayed, then the existing note track is redrawn according to the cleared report point data of the existing note track, the erasing effect can be displayed in real time, and when the font, the font size, the line spacing and the like in the current reading page are changed, the existing note track is redrawn according to the cleared report point data of the existing note track during redisplay, and the existing note track can still be normally reproduced.
EXAMPLE III
Fig. 3 is a flow chart illustrating a note processing method according to the third embodiment of the present invention. The embodiment is further optimized on the basis of the embodiment. As shown in fig. 3, the method includes:
and S310, responding to a note erasing operation generated by the current page read by the ink screen reader, and acquiring a note erasing track generated along with the note erasing operation.
And step S320, recording the coordinates of the intersection point of the note erasing track and the existing note track according to the note erasing track and the report point data of the existing note track.
The report point data of the note erasing track comprises coordinates and erasing width information of each report point in the note erasing track, the report point data of the existing note track comprises coordinates of each report point in the existing note track, crossed coordinates in the note erasing track are traversed according to the coordinates of each report point in the existing note track, and the crossed coordinates of the report points are used as crossed coordinates. Specifically, when traversing the crossed coordinates in the note erasing track, the coordinates and erasing width information of each report point in the note erasing track are comprehensively considered, that is, whether the coordinate point of the existing note track is crossed in the width area of the note erasing track is considered.
And when the coordinates of the report points of the note erasing track and the existing note track are determined to have no crossed report point coordinates according to the coordinates and the erasing width information of the report points of the note erasing track and the coordinates of the report points of the existing note track, selecting a coordinate point closest to the edge of the note erasing track from the report point coordinates of the existing note track as a crossed point coordinate. Specifically, when the closest coordinate point is determined, the erasing width information of the note erasing track is considered, and the coordinate point closest to the edge of the note erasing track is selected from the report point coordinates of the existing note erasing track as the intersection point coordinate according to the erasing width information.
Step S330, clearing the report point data of the existing note track between the cross points.
Specifically, there may be multiple intersections, which may divide the existing note track into multiple segments. Taking an existing handwriting as an example, after an erasing operation is finished, for example, a pen is detected to be lifted, the newspaper point data of a line segment between the intersection points of the existing handwriting is cleared, according to the newspaper point data coordinate point generating sequence during the existing handwriting drawing, the coordinates of the prior intersection points are respectively marked as pen lifting coordinates, namely starting point coordinates, and the coordinates of the subsequent intersection points are marked as pen falling coordinates, namely end point coordinates, so as to form two independent line segments, namely, each line segment comprises pen falling coordinates and pen lifting coordinates. The case of erasing into multiple segments is similar and this step can be considered as erasing on the data.
And step S340, redrawing the existing note track according to the eliminated report point data of the existing note track.
Therefore, the erasing operation is realized by recording the intersection coordinates of the note erasing track and the existing note track, the existing note track is redrawn according to the removed report data of the existing note track, the erasing effect can be displayed in real time, and when the font, the font size, the line spacing and the like in the current reading page are changed, the existing note track is redrawn according to the removed report data of the existing note track during redisplay, and the existing note track can still be normally reproduced.
Example four
Fig. 4 is a flowchart illustrating a note processing method according to another embodiment of the present invention.
The embodiment is further optimized on the basis of the embodiment. As shown in fig. 4, the method includes:
and step S410, responding to a note erasing operation generated by the current page read by the ink screen reader, and acquiring a note erasing track generated along with the note erasing operation.
Step S420, according to the note erasing track and the report data of the existing note track, the report data to be eliminated in the existing note track is determined, and the report data to be eliminated in the existing note track is eliminated.
Step S430, acquiring a new line generated in the cleared existing note track.
Specifically, a new line generated in the existing note track may be determined according to the removed report point data of the existing note track, and after the note erasing operation, the existing note track may be divided into one or more lines, so that the new line determined according to the removed report point data of the existing note track may be one or more lines.
Step S440, searching preset characters in a preset range according to the start point coordinates and the end point coordinates of the new lines.
Specifically, since there is a corresponding relationship between the existing note track and the text of the current reading page, when there is one new line, preset text in a preset range, for example, text directly above or below the start point coordinate and text directly above or below the end point coordinate, are searched according to the start point coordinate and the end point coordinate of the new line. And when the number of the new lines is multiple, searching for preset characters in a preset range according to the corresponding start point coordinates and the corresponding end point coordinates respectively based on the start point coordinates and the end point coordinates determined by each line.
Step S450, establishing a corresponding relation between the coordinates of the starting point and the ending point of the new line and the offset of the preset characters.
Specifically, since the offset of the text itself in the e-book source file is not changed, the corresponding relationship between the start point coordinate and the end point coordinate and the offset of the text can be established.
Step S460, determining corresponding preset characters according to the start point coordinates and the end point coordinates of the new line, and redrawing the existing note track based on the corresponding preset characters.
Specifically, because the offset of the text itself in the e-book source file is not changed, by establishing the corresponding relationship between the start point coordinate and the offset of the end point coordinate and the offset of the preset text, even if the page style of the current reading page is changed and the position of the preset text on the page is changed, the new position coordinate of the preset text can be found according to the offset of the preset text, so that the start point coordinate and the end point coordinate of a new line are changed according to the new position coordinate, each report point coordinate between the start point and the end point is synchronously updated according to the changed start point coordinate and end point coordinate, and the existing note track is redrawn according to each report point coordinate.
Therefore, in the embodiment, by establishing the corresponding relationship between the start point coordinate and the end point coordinate of the new line and the offset of the preset character, when the page styles such as the font, the font size, the line spacing and the like in the current reading page are changed, the new position coordinate of the preset character is found according to the offset of the preset character during redisplay, so that the existing note track is redrawn, and the normal reappearance of the reading page can still be ensured.
