Abstract
Description
Technical Field
[0001] This invention relates to the field of animation processing technology, and in particular to an animation extension and a method, apparatus, device and medium for playing extended animation. Background Technology
[0002] APNG, WebP, and GIF are currently the mainstream animated image formats, widely used in mobile applications, web page interactions, and other scenarios. In existing technologies, these animated image formats all provide a fixed animation effect. "Fixed" here means that the effect is completely consistent regardless of the playback scenario; each resource is designed for a specific scenario. If animation resources need to make even minor differences in effect for different situations, each effect must be exported as a separate resource file. This makes it impossible to dynamically insert custom content (such as personalized images or text information), resulting in low resource reuse, increased time costs, and greater difficulty in resource management.
[0003] Currently, one resource format that allows for the dynamic insertion of custom images and text is VAP (VideoAnimationPlayer). However, VAP is based on MP4, meaning its playback consumes significantly more memory and CPU than typical animated image resources, making it unsuitable for large-scale deployments.

Furthermore, "and / or" indicates at least one of the connected objects, and the character " / " generally indicates that the preceding and following objects are in an "or" relationship.
[0046] The following is combined Figures 1 to 5 This invention describes an extension of animation and a method, apparatus, device, and medium for playing extended animation.
[0047] like Figure 1 As shown, the present invention provides an extended method for animation, comprising:
[0048] Step 110: Parse the original animation file to obtain the original animation sequence frames and the animation configuration in protobuf format. The original animation file can be in any of the following formats: APNG, WebP, or GIF. The animation configuration includes the size and frame rate information of the original animation.
[0049] Specifically, the original animation resources are completely parsed and broken down into a series of frame sequences using a tool. Starting from the first frame, PNG images with frame numbers are generated sequentially, such as naming the first frame 000.png, the second frame 001.png, and so on. The animation configuration is then parsed and obtained in protobuf format, containing all information about the original animation resources, such as size, frame rate, etc.
[0050] Step 120: Import the target mask sequence frame of the target mask resource, extract the valid information of the mask sequence frame, and generate a mask configuration in protobuf format. The valid information includes the position, size, and scaling of the non-transparent area in the mask sequence frame.
[0051] Specifically, the target mask resource is a new resource that will be displayed on top of the original animation resource. The target mask resource can be displayed as either a static PNG image or text. That is, static PNG images or text can be dynamically mounted on the original animation. The appearance frame (i.e., the frame in which the static PNG image or text appears), position, size, and color value of these static PNG images and text can be defined by the mask configuration. Users can specify in the mask configuration whether the mask is displayed as a static PNG image or text, and the text can further specify its size and color. Each target mask sequence frame is considered an independent layer with a unique mask name to distinguish different mask layers. In some embodiments, the target mask sequence frames are named according to the sequence number drawn on the corresponding original animation sequence frame. The target mask sequence frame image is named as a PNG image with the corresponding frame number, in the form of three digits followed by a .png suffix, such as 000.png, 999.png, etc.
[0052] In some embodiments, importing the target mask sequence frame and extracting valid information from the mask sequence frame includes:
[0053] Import the target masking sequence frames;
[0054] The transparent and non-transparent areas in the masking sequence frames are identified based on transparency.
[0055] Extract the boundary coordinates, width and height dimensions, and scaling factor of the non-transparent area to determine the valid information.
[0056] In this embodiment, non-transparent areas (areas with non-zero transparency) are filtered out by pixel transparency detection, and their boundary coordinates, width and height dimensions, and scaling factor are obtained. The purpose of importing the target mask sequence frame is to read its effective information, specifically the position and size of the non-transparent areas, scaling factor, etc., within the mask sequence frame. The essence of the mask sequence frame is to carry the effective display area, i.e., the mask area that the user can actually see. Therefore, only the effective information of the non-transparent areas is extracted, not the information of the entire canvas area of the mask sequence frame. For example, if the canvas of the mask sequence frame is 500×500 pixels, but only the central 100×100 pixel area has non-zero transparency while the rest is completely transparent, then only the effective information of this 100×100 pixel area is extracted to generate a mask configuration in the same protobuf format, ensuring compatibility between the mask and the original animation.
[0057] In some embodiments, after identifying the transparent and non-transparent regions in the mask sequence frames based on transparency, the process includes:
[0058] Based on the boundary coordinates of the non-transparent area, determine whether the shape of the non-transparent area is rectangular or circular;
[0059] If yes, then the step of extracting the boundary coordinates, width and height dimensions, and scaling factor of the non-transparent area and determining them as valid information is performed; if no, then non-rectangular and non-circular non-transparent areas are filtered out.
[0060] To reduce configuration size and improve the efficiency of subsequent masking processing, this embodiment only supports rectangular and circular masks. The mask configuration limits the mask shape to rectangular or circular; other shapes will be filtered out. The coordinate calculation and scaling logic for rectangles and circles are simple, adaptable to multiple platforms for efficient rendering, reducing the computational complexity of mask drawing and ensuring smoothness when the extended player is dynamically mounted.
[0061] To further reduce the size of the configuration and improve the efficiency of subsequent masking processing, in some embodiments, it is also determined whether the size of the target masking sequence frame is not greater than the original animation size, and whether the number of target masking sequence frames does not exceed the number of original animation sequence frames. If the size of the target masking sequence frame is greater than the original animation size or the number of target masking sequence frames exceeds the number of original animation sequence frames, it is considered invalid input and is filtered out.
[0062] Once the valid information is confirmed, record the masking parameters in protobuf format and generate the masking configuration. The masking configuration can include the masking display type (static PNG image / text), masking size, text color, display frame range, and unique masking name (to distinguish multiple layers of masks).
[0063] Step 130: Merge the animation configuration and the mask configuration into a unified protobuf configuration file, write the unified protobuf configuration file into the resource header of the original animation file, and export the extended animation file.
[0064] Specifically, the animation configuration and masking configuration are combined into a final protobuf file. This file, as the playback configuration for the animation resource, is written into the resource header of the original animation file without damaging the core data of the original animation. This ensures that the original player can play the original animation effect normally. The modified animation resource is then exported as the extended animation file. The final exported animation format can be different from the original animation format, such as converting GIF to WebP, to maximize performance optimization on different platforms.
[0065] Correspondingly, such as Figure 2 As shown, the present invention also provides a method for playing extended animations, which can be applied to extended players, specifically including the following steps:
[0066] Step 210: Obtain the extended animation file.
[0067] Step 220: Parse the unified protobuf configuration in the extended animation file and obtain the corresponding target mask resource through the interface.
[0068] Step 230: Play the extended animation file and dynamically draw the target mask resource to the corresponding position of the original animation sequence frame according to the unified protobuf configuration to achieve the mask mounting effect.
[0069] Specifically, the extended player has a built-in protobuf parser that reads and parses the unified protobuf configuration in the extended animation file resource header to obtain the animation configuration and mask configuration. It then retrieves the corresponding target mask resource through an interface. During playback, the extended player matches the corresponding mask based on the frame number of the current original animation sequence frame. According to the position and size configured in the mask configuration, the target mask resource is drawn to the corresponding layer of the original animation frame, achieving the mask mounting effect. Specifically, the masks are drawn according to their priority order to ensure the correct display logic for multiple mask layers.
[0070] For example, if the text content "Limited-time offer" is obtained through the interface, the corresponding mask configuration includes: appearing frames 10 to 50, position coordinates (500, 300), text size 24, and text color red. Then, when the original animation plays to frame 10, the red 24-point text "Limited-time offer" will be drawn at the original animation coordinates (500, 300) and will continue until frame 50. When the animation plays to frame 51, "Limited-time offer" will no longer be displayed.
[0071] It's important to note that users can configure what custom resources are displayed under the overlay (the player obtains this information via a method interface before playback begins; it cannot be modified at the start of playback, and any modifications require replaying the resource). During image resource playback, the player renders the image based on the current frame and the configuration of the custom resource, ultimately producing a single resource that adapts to different scene variations. For example, if the same original animation resource needs to be used, and the text "New Product Launch" is attached to it, there's no need to recreate the animation resource. Simply modify the custom text content in the extended player via an interface, and the overlay text will dynamically replace the overlay text during playback, enabling the reuse of a single resource across multiple scenes.
[0072] The aforementioned extended player is a dedicated animation player customized and developed based on the technical solution of this invention. Its core positioning is to be compatible with the original animation playback and the ability to dynamically mount new masking. It retains playback support for standard formats such as APNG, WebP, and GIF, and can also parse the extended animation files of this invention (the resource header contains a unified protobuf configuration). Through the interface, it can obtain user-defined masking resources (static images / text) and dynamically draw the masking content frame by frame during playback, realizing the adaptation of one set of resources to multiple scenarios.
[0073] The above-described method for extending and playing extended animation has the following beneficial technical effects compared with existing technologies:
[0074] 1. Achieve lightweight extension of the original animation format without reconstructing the core data of the animation file: Generate and merge configurations through protobuf format, write unified configurations only in the resource header of the original animation file, do not destroy the main content of the original animation, ensure that the original player can play the original animation effect normally, be compatible with the existing animation resource ecosystem, and do not need to discard existing resources;
[0075] 2. Significantly improve the reuse rate of animation resources and reduce development and management costs: The extended animation files can dynamically mount mask resources through subsequent extended players. One set of resources can adapt to the effect differences of multiple scenes. There is no need to export multiple independent resources for minor differences, reducing resource redundancy and management difficulty.
[0076] 3. Small configuration size and high parsing efficiency: Relying on the serialization advantages of protobuf, the size increase of the merged configuration file is minimal, and the parsing speed is fast, which will not significantly increase the storage and transmission costs of animation files, while adapting to the fast parsing needs of multiple platforms.
[0077] 4. Unified extension logic and compatibility with multiple original animation formats: For mainstream animation formats such as APNG, WebP, and GIF, a consistent "parse-configure-merge" process is adopted, eliminating the need to design differentiated extension solutions for different formats and reducing cross-format development and adaptation costs;
[0078] 5. Lay a stable foundation for dynamic mounting functionality: By extracting effective information from the non-transparent areas of the mask sequence frames and standardizing the configuration, the core parameters of the mask are clarified, ensuring that subsequent extended players can accurately parse and efficiently draw the mask content, thus guaranteeing the stability and smoothness of the dynamic mounting effect.
