主要修改内容：
（1）版本新增

  • Android 端新增 harfbuzz 版本（带 -harfbuzz 后缀），用于支持多字节 emoji 表情的显示。
  • 新增企业版 SDK（带 -enterprise 后缀），包含音频播放、素材加密，占位图一键替换视频，导出视频文件等高阶功能。

（2）AE 特性：

  • 色相/饱和度（Hue/Saturation）
  • 亮度和对比度（Brightness & Contrast）
  • 3D 图层 (3D Layer)

（3）接口新增：

  • 新增 PAGImageView 类：针对 UI 场景设计的专用播放组件，基于图片解码器+磁盘缓存模式，能够避免 OpenGL 跟 UI 视图桥接的额外开销，大幅降低内存和 CPU 占用。
  • 新增 PAGDecoder 类：支持通过 PAGFile 或 组合的 PAGComposition 创建，将 PAG 当做标准图片解码器使用，快捷获取某一帧的渲染内容。
  • PAGSurface 类：新增 copyPixelsTo 接口，支持将 PAGSurface 渲染的像素内容拷贝至业务方给定的内存地址。

（4）能力优化：

  • 文本渲染支持含有多个 unicode 的 emoji 表情 （Android 侧需要使用 harfbuzz 版本）。
  • DisplacementMap 现已支持所有图层类型，不限制用于 BMP 预合成图层。
  • PAGView 播放首帧渲染优化，避免出现首帧跳帧播放。
  • 优化存在多个图层交错引用同一个 BMP 预合成情况下的播放卡顿问题。

Main revisions:
（1）New version

  • A new harfbuzz version (with -harfbuzz suffix) is added to Android to support the display of multi-byte emoji expressions.
  • A new enterprise version SDK (with -enterprise suffix) is added, including audio playback, material encryption, one-click replacement of video with placeholder image, export of video files and other advanced functions.

（2）AE features:

  • Hue/Saturation
  • Brightness & Contrast
  • 3D Layer

（3） New interface:

  • Added PAGImageView class: a dedicated playback component designed for UI scenes. Based on the image decoder + disk cache mode, it can avoid the additional overhead of bridging OpenGL and UI views, and significantly reduce memory and CPU usage.
  • Added PAGDecoder class: supports creation through PAGFile or PAGComposition combined, using PAG as a standard image decoder to quickly obtain the rendering content of a certain frame.
  • PAGSurface class: Added copyPixelsTo interface to support copying the pixel content rendered by PAGSurface to the memory address given by the business party.

(4) Capability optimization:

  • Text rendering supports emoji expressions containing multiple unicodes (the Android side requires the harfbuzz version).
  • DisplacementMap now supports all layer types and is not restricted to BMP precomposed layers.
  • The rendering of the first frame of PAGView playback is optimized to avoid skipping the first frame of playback.
  • Optimize the playback lag issue when multiple layers interleave reference to the same BMP pre-synthesis.
