PNG 图片标准时隔 20 多年正式更新第三版：HDR、动图、Exif 支持等 PNG（Portable Network Graphics）第三版标准于6月24日正式发布，并被标记为 W3C 推荐标准。该标准旨在改进动图功能，支持高动态范围（HDR）图像，并整合自第二版以来报告的错误修复。新版本核心规范增加了广泛采用的 Animated PNG（APNG）动图格式。APNG 在 2004 年和 2005 年期间被创建并完善，但此前曾被 PNG 开发组拒绝。第三版规范使 APNG 规范与过去十年的内容和实现保持一致。此外，PNG 第三版还新增了 HDR 支持，添加 cICP 块用于包含图像格式元数据，使 PNG 能够包含 HDR 和广色域（WCG）图像。此前定义的 Exif 内容也被移至规范的主体部分。IT之家 | W3C 🏷#PNG#APNG#HDR 📢频道👥群组📝投稿
