Installation

TODO

  • test OctTreeQuantizer (only 256 colors?)
  • complete ImageMagikQuantizer
  • Lanczos3 filter using AWT API
  • BufferedImageOp ???
  • https://github.com/iariro/N88BasicImage
  • ffmpeg resize 4byte 32bit operation is wrong
  • DaVinchi (wip, branch:davinch)
  • n88basic image format (wip, branch:n88basic)
  • yet another pic image format (wip, branch:pic)

Tech Know

  • Mac Open JDK's JNI library extension is .dylib already common
  • libsescale has MMX bug, this causes segmentation fault when resizing image.
