Each frame can be encoded as-is (I-frame), or can represent a delta from the previous frame (P-frame). In both cases the data is compressed in standard PNG format.<br /> <br /> It uses the [[FourCC]] code png1.<br /> <br /> The codec supports RGB[A] and YUV colorspaces: In RGB mode every frame is compressed as a PNG image; in YUV mode a frame is stored as 3 PNG images with order Y, U, V.<br /> <br /> CorePNG was originally developed for use with subtitles, but evolved into a lossless codec that claims sometimes to outdo Huffyuv and Loco in terms of compression.<br /> <br /> <br /> <br /> == Links ==<br /> * [https://web.archive.org/web/20070906193803/http://corecodec.org/projects/corepng/ Homepage (archived)]<br /> * [https://web.archive.org/web/20040117230558/http://corecodec.org:80/download.php/87/CorePNG-VFW-v0.8.1.exe v0.8.1 Video for Windows codec plus source code]<br /> * [https://web.archive.org/web/20040117231829if_/http://corecodec.org:80/download.php/96/CorePNG-VFW-v0.8.2.exe v0.8.2 Video for Windows codec plus source code]<br /> * [https://github.com/qyot27/CorePNG Github source mirror]<br /> * [https://www.afterdawn.com/glossary/term.cfm/corepng Afterdawn info page]<br /> * [https://wiki.multimedia.cx/index.php/CorePNG wiki.multimedia.cx]<br /> * [http://forum.doom9.org/showthread.php?t=64139 doom9 thread]<br /> * [https://de.wikipedia.org/wiki/CorePNG German Wikipedia]</div>
