Detailed Implementation

[0022] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0023] In related technologies, when creating animated stickers from a large amount of material, each material needs to be converted and processed sequentially, which takes a long time and is inefficient. To solve the above technical problems, this invention discloses a method for creating animated stickers. The core concept involves obtaining at least one target file in a preset format. The target file includes: file header data, byte sequences, and an index list. The byte sequences are determined by converting image data, and the image data is determined based on a set of material images. The index elements of the index list indicate the identifier of each byte sequence and the number of bytes in each byte sequence. For a target file in a preset format, a preset software development kit is called to read the target file and determine its file header data. Based on the file header data, the index list is read from the target file. Based on the identifier of each byte sequence in the index list and the number of bytes in each byte sequence, each byte sequence is read from the target file. Based on each byte sequence, the corresponding image data is determined. The image data is rendered based on the file header data to obtain the target animated sticker. Therefore, when faced with multiple sets of source images, it is only necessary to obtain the target file in the preset format corresponding to each set of source images, then call the preset software development kit to determine the image data corresponding to each set of source images, and finally render the image data according to the file header data of each preset format target file to obtain multiple target animated stickers. This enables batch conversion of multiple sets of source images to obtain multiple target animated stickers, improving the production efficiency of animated stickers.

[0024] Reference Figure 1 The diagram illustrates a flowchart of a method for creating an animated sticker according to an embodiment of the present invention. The method may specifically include the following steps: Step 101: Obtain at least one target file in a preset format; the target file includes: file header data, byte sequences, and an index list; the byte sequences are determined by converting image data; the image data is determined based on a set of source images; the index elements of the index list are used to indicate the identifier of each byte sequence and the number of bytes in each byte sequence.

[0025] In this invention, the method for creating animated stickers can be applied to electronic devices, such as mobile phones, tablets, and computers. Pre-installed applications can be deployed on the electronic terminals, and the method for creating animated stickers can be based on these applications. In this invention, at least one target file in a preset format can be obtained first. Each target file in the preset format corresponds to a set of source images. Each preset target file can include: file header data, a byte sequence, and an index list. The byte sequence is determined by converting the image data, and the image data is determined based on a set of source images. The index elements of the index list indicate the identifier of each byte sequence and the number of bytes in each byte sequence.

[0026] Step 102: For a target file in the preset format, call the preset software development kit to read the target file and determine the file header data of the target file.

[0027] In this invention, the processing method is the same when dealing with multiple sets of image materials, i.e., multiple target files in preset formats, as it is when dealing with a single set of image materials, i.e., a single target file in preset formats. The only difference is that when dealing with multiple sets of image materials, each set of image materials is processed simultaneously. To facilitate understanding and description of the embodiments of this invention, this invention will use a single target file in preset formats as an example for illustration. When dealing with a single target file in preset formats, a preset software development kit can be called to read the target file in preset formats and then determine the file header data of the target file in preset formats.

[0028] Step 103: Based on the file header data, read the index list from the target file.

[0029] In this invention, after determining the header data of the target file, the index list can be read from the target file based on the header data.

[0030] Step 104: Read each byte sequence from the target file according to the identifier of each byte sequence in the index list and the number of bytes in each byte sequence.

[0031] In this embodiment of the invention, after reading the index list from the target file, each byte sequence can be read from the target file according to the identifier of each byte sequence in the read index list and the number of bytes in each byte sequence, wherein one byte sequence corresponds to one material image in a group of material images.

[0032] Step 105: Determine the corresponding image data based on each byte sequence.

[0033] In this invention, after obtaining each byte sequence, the corresponding image data can be determined based on each byte sequence.

[0034] Step 106: Render the image data according to the file header data to obtain the target animated sticker.

[0035] In this invention, after determining the image data, the image data can be rendered according to the file header data to obtain the target animated sticker. In this invention, when multiple target animated stickers need to be made for multiple sets of material images, the target files in preset formats corresponding to multiple sets of material images can be obtained. Then, according to the animated sticker making method of this invention, the target files in multiple preset formats are processed simultaneously to obtain the target animated stickers corresponding to multiple sets of material images. Thus, the corresponding animated stickers can be made in batches for multiple sets of material images.

[0036] In this embodiment of the invention, at least one target file in a preset format is obtained. The target file includes: header data, byte sequences, and an index list. The byte sequences are determined by converting image data. The image data is determined based on a set of source images. The index elements of the index list indicate the identifier of each byte sequence and the number of bytes in each byte sequence. For a target file in a preset format, a preset software development kit (SDK) is invoked to read the target file and determine its header data. Based on the header data, the index list is read from the target file. Based on the identifier of each byte sequence in the index list and the number of bytes in each byte sequence, each byte sequence is read from the target file. Based on each byte sequence, the corresponding image data is determined. The image data is rendered based on the header data to obtain the target animated sticker. Therefore, when dealing with multiple sets of source images, only the target file in the preset format corresponding to each set of source images needs to be obtained. Then, the preset application development kit is invoked to determine the image data corresponding to each set of source images. Finally, the image data is rendered based on the header data of each target file in the preset format to obtain multiple target animated stickers. This achieves batch conversion of multiple sets of source images to obtain multiple target animated stickers, improving the production efficiency of animated stickers.

[0037] Reference Figure 2 The diagram illustrates a flowchart of another method for creating animated stickers according to an embodiment of the present invention. The method may specifically include the following steps: Step 201: Obtain at least one set of source images.

[0038] In this embodiment of the invention, at least one set of source images can be obtained first. These source images can consist of static images or dynamic images.

[0039] In this invention, when a user needs to create animated stickers, they can open a preset application. Once opened, the preset application displays controls for converting static images to animated stickers and controls for converting animated images to animated stickers. For example... Figure 3 The diagram shows a schematic of a display interface for creating animated stickers according to an embodiment of the present invention.

[0040] When a user needs to convert a static image into an animated sticker, they can click the "Static Image to Animated Sticker" control to proceed to the next display screen, such as... Figure 4 The diagram shows another display interface for creating animated stickers provided by an embodiment of the present invention. Figure 4 The display interface includes a static image control, which allows users to upload source images that they want to turn into animated stickers. Figure 4 The display interface also includes a confirmation control. When a user needs to create multiple animated stickers, that is, when a user needs to upload multiple sets of static images, they can click the confirmation control after uploading one set of static images. The application will then confirm this set of static images as a set of material images. After clicking the confirmation control, the user can click the add static image control to upload a second set of material images.

[0041] When a user needs to convert an animated GIF into an animated sticker, they can click the "Animated GIF to Animated Sticker" control to proceed to the next display screen, such as... Figure 5 The diagram shows another display interface for creating animated stickers provided by an embodiment of the present invention. Figure 5 The display interface includes a control for adding animated images. Users can click the control to upload source images that they want to turn into animated stickers. Figure 5 The display interface also includes a confirmation control. When a user needs to create multiple animated stickers, i.e., upload multiple sets of animated images, they can click the confirmation control after uploading one set of animated images. The application will then automatically recognize this set of animated images as a set of source images. After clicking the confirmation control, the user can then click the "Add Animated Image" control to upload a second set of source images. In this invention, Figure 4 and Figure 5 It may also include a material information display area and other functional controls (not shown in the figure), such as a clear list control, a set keep path control, and a return to homepage control.

[0042] Step 202: For a set of material images, determine the image data corresponding to the material images, and convert each image data to obtain a byte sequence corresponding to each image data.

[0043] In this embodiment of the invention, after acquiring at least one set of source images, the user can click... Figure 4 and Figure 5 The conversion control in the program allows the application to determine the image data corresponding to each set of source images. For example, if a set of source images contains animated images, the QImageReader interface can be used to obtain the image of each frame of each animated image, i.e., obtain the static image corresponding to the animated image. Then, all static images in the set of source images are traversed to obtain the QImage of each static image, i.e., obtain the image data corresponding to each static image. Then, each QImage is converted to obtain the QByteArray byte sequence corresponding to each image data. In this invention, determining the corresponding byte sequence for multiple sets of source images is the same as determining the corresponding byte sequence for a single set of source images. When dealing with multiple sets of source images, each set of source images can be converted simultaneously to obtain the byte sequence corresponding to each set of image source images.

[0044] Step 203: Generate an index list.

[0045] In this embodiment of the invention, after determining the byte sequence corresponding to each image data, an index table can be generated based on the determined direct sequence.

[0046] In one embodiment, generating an index list includes: determining the number of bytes in each byte sequence based on the byte sequence corresponding to each image data; determining the offset of each byte sequence based on the number of bytes in each byte sequence; the offset is used to indicate the starting position of the byte sequence; and generating an index list based on the identifier, number of bytes, and offset of each byte sequence.

[0047] In this invention, after determining the byte sequence corresponding to each image data, the number of bytes in each byte sequence can be determined first. For example, for three static images A1, B1, and C1, the corresponding image data is determined to be A2, B2, and C2, and the corresponding byte sequences are determined to be A3, B3, and C3. The number of bytes in the three byte sequences are 2000 bytes, 2200 bytes, and 1800 bytes, respectively. Then, the offset of byte sequence A3 can be determined to be 0, the offset of byte sequence B3 to be 2000, and the offset of byte sequence C3 to be 4200. Finally, an index table can be generated based on the identifier, number of bytes, and offset of each byte sequence. The following table (1) is an example of a generated index table:

[0048] Table (1) Step 204: Obtain the file header data.

[0049] In this embodiment of the invention, after generating the index list, the file header data can be obtained.

[0050] In one embodiment, obtaining file header data may include: obtaining data parameters; the data parameters include: rendering parameters, the number of bytes in the file header data, and the total number of bytes in all the byte sequences; The data parameters are filled into a preset data structure to obtain the file header data.

[0051] In this invention, such as Figure 4 and Figure 5 The display interface includes a data parameter setting area where users can fill in data parameters as needed. These parameters can include rendering parameters. The number of bytes in the file header data can be preset. After obtaining the data parameters, the application can automatically fill them into a preset data structure to obtain the file header data. The following is a data structure for the file header data after automatically filling in the preset data structure: Struct NvFileHeader { int version; / / Version number: 4 bytes; int headerSize; / / File header size, 4 bytes; fixed at 64, meaning the total file header information occupies 64 bytes; String imageFormat; / / Image format: PNG or JPG, 4 bytes; int imageWidth; / / Image width, 4 bytes; int imageHeight; / / Image height, 4 bytes; int frameRate; / / Frame rate, 4 bytes; int frameCount; / / Number of frames, 4 bytes; int defaultLoopMode; / / Loop mode: loop from the beginning, repeat the last frame, 4 bytes; long frameIndexTableOffset; / / File offset position of all images, 4 bytes; } Step 205: Encapsulate the file header data, the byte sequence, and the index list to obtain a target file in a preset format.

[0052] In this embodiment of the invention, after obtaining the file header data, the file header data, byte sequence, and index list can be sequentially encapsulated into a file of a preset format to obtain a target file of the preset format. Alternatively, the byte sequence can be written into the file of the preset format first, then the file header data can be written into the beginning text of the file of the preset format, and finally the index list can be written into the end of the file to obtain a target file of the preset format. In this invention, the file of the preset format can be an animatesticker file.

[0053] Step 206: Obtain at least one target file in a preset format.

[0054] In this embodiment of the invention, step 206 is the same as step 101, and will not be described again here.

[0055] Step 207: For a target file in the preset format, call the preset software development kit, read the target file, and determine the file header data of the target file.

[0056] In this embodiment of the invention, the preset application can call a preset software development kit to obtain target files. When there are multiple target files with preset formats, the preset software development kit can be called to obtain multiple target files and determine the file header data corresponding to each target file.

[0057] Step 208: Based on the file header data, read the index list from the target file.

[0058] In this invention, after determining the header data of the target file, the index list can be read from the target file based on the header data.

[0059] In one embodiment, the file header data includes: the number of bytes in the file header data and the total number of bytes in all byte sequences; reading an index list from the target file based on the file header data includes: reading an index list from the target file based on the number of bytes in the file header data and the total number of bytes in all byte sequences.

[0060] In this invention, after determining the header data of the target file, the number of bytes in the header data and the total number of bytes in all byte sequences can be read first. For example, if the header data is 64 bytes and the total number of bytes in all byte sequences is 6000 bytes, then the first 64 bytes in the target file are the header data, bytes 65 to 6054 are all byte sequences, and bytes 6055 and the remaining bytes are all data belonging to the index list. Thus, the index list is obtained by reading from byte 6055.

[0061] Step 209: Read each byte sequence from the target file according to the identifier of each byte sequence in the index list and the number of bytes in each byte sequence.

[0062] In this embodiment of the invention, after reading the index list from the target file, each byte sequence can be read from the target file according to the identifier of each byte sequence in the read index list and the number of bytes in each byte sequence, wherein one byte sequence corresponds to one material image in a group of material images.

[0063] In one embodiment, reading each byte sequence from the target file based on the identifier of each byte sequence in the index list and the number of bytes in each byte sequence includes: determining the position of each byte sequence from the target file based on the identifier of each byte sequence in the index list and the offset of each byte sequence; and reading each byte sequence from the target file based on the position of each byte sequence and the number of bytes in each byte sequence.

[0064] For example, if the index list is read as shown in Table (1) above, then we can obtain that the number of bytes corresponding to the identifier A3 of the byte sequence is 2000 bytes, the offset of the byte sequence A3 is 0, the number of bytes corresponding to the identifier B3 of the byte sequence is 2200 bytes, the offset of the byte sequence B3 is 2000, the number of bytes corresponding to the identifier C3 of the byte sequence is 1800 bytes, and the offset of the byte sequence A3 is 4200. Then we can determine that the total number of bytes in all byte sequences is 6000 bytes. Among these 6000 bytes, the first byte is the starting position of the byte sequence A3, the 2001st byte is the starting position of the byte sequence B3, and the 4201st byte is the starting position of the byte sequence C3. Then, the 2000 bytes obtained from the first byte of these 6000 bytes are the data of the byte sequence A3, the 2200 bytes obtained from the 2001st byte are the data of the byte sequence B3, and the 1800 bytes obtained from the 4201st byte are the data of the byte sequence C3.

[0065] Step 210: Determine the corresponding image data based on each byte sequence.

[0066] In this invention, after obtaining each byte sequence, each byte sequence can be converted to obtain image data corresponding to each byte sequence.

[0067] Step 211: Render the image data according to the file header data to obtain the target animated sticker.

[0068] In this invention, after determining the image data, the image data can be rendered according to the file header data to obtain the target animated sticker. In this invention, when multiple target animated stickers need to be made for multiple sets of material images, the target files in preset formats corresponding to multiple sets of material images can be obtained. Then, according to the animated sticker making method of this invention, the target files in multiple preset formats are processed simultaneously to obtain the target animated stickers corresponding to multiple sets of material images. Thus, the corresponding animated stickers can be made in batches for multiple sets of material images.

[0069] For example, based on the byte sequence A3, B3, C3, the corresponding image data is determined to be A2, B2, C2. The image data A2, B2, C2 are then rendered based on the file header data to obtain the final target animated sticker.

[0070] In one embodiment, the file header data includes: sticker frame rate and sticker loop mode; rendering the image data according to the file header data to obtain the target animated sticker includes: rendering the image data according to the sticker frame rate and sticker loop mode to obtain the target animated sticker.

[0071] In this invention, the file header data may include: sticker frame rate and sticker loop mode. For example, if the sticker frame rate is 10fps and the sticker loop mode is loop from beginning to end, then the image data can be rendered according to this sticker frame rate and sticker loop mode to obtain the target animated sticker. In this invention, the file header data may also include data parameters such as the sticker size.

[0072] In this invention, when faced with multiple sets of source images, for example, when faced with set a, set b, and set c source images, indicating that three animated stickers need to be created for each of the three sets of source images, the animated sticker creation method of this embodiment can be used to process set a, set b, and set c source images simultaneously to obtain three animated stickers that correspond one-to-one with set a, set b, and set c source images. This enables batch production of animated stickers and improves the efficiency of animated sticker production.

[0073] In this embodiment of the invention, at least one target file in a preset format is obtained. The target file includes: header data, byte sequences, and an index list. The byte sequences are determined by converting image data. The image data is determined based on a set of source images. The index elements of the index list indicate the identifier of each byte sequence and the number of bytes in each byte sequence. For a target file in a preset format, a preset software development kit (SDK) is invoked to read the target file and determine its header data. Based on the header data, the index list is read from the target file. Based on the identifier of each byte sequence in the index list and the number of bytes in each byte sequence, each byte sequence is read from the target file. Based on each byte sequence, the corresponding image data is determined. The image data is rendered based on the header data to obtain the target animated sticker. Therefore, when dealing with multiple sets of source images, it is only necessary to obtain the target file in the preset format corresponding to each set of source images, then invoke the preset SSD to determine the image data corresponding to each set of source images, and finally render the image data based on the header data of each target file in the preset format to obtain multiple target animated stickers. This achieves batch conversion of multiple sets of source images to obtain multiple target animated stickers, improving the production efficiency of animated stickers.
