软件原名：APNG Assembler 汉化名称：APNG编译器 软件介绍： APNG Assembler creates APNG animation from PNG/TGA image sequence. A number of optimization techniques used to make APNG files as small as possible: inter-frame optimization utilizing alpha-blend and dispose operations, smaller than the full-size subframes, dirty transparency, color type and palette optimizations, and various compression options: zlib, 7zip, Zopfli. 简单来说，这个就是用来生成APNG格式的动图的程序。 APNG文件，全称“Animated Portable Network Graphics”，是一个基于PNG的位图动画格式。这种格式的文件是比GIF文件更小、更清晰的动图文件，它克服了GIF文件色深不足、体积大、不支持Alpha通道的缺点，是新一代的动图格式文件。 界面展示：
