These options determine how PMView saves OS/2 Bitmap files.
OS/2 2.x This will save the file with a header that is compatible with OS/2 version 2.x and Windows 3.x. RLE encoding can be used for 4, 8 and 24 bit images and 1 bit images may be Huffman 1D encoded.
OS/2 1.x This will save the file with a header that is compatible with OS/2 version 1.x and above. Encoding cannot be used.
Use RLE/Huffman 1D Encoding If set, PMView will RLE or Huffman1D encode the bitmap if the format you have selected supports encoding. Note that this usually only is suitable for images with large areas of the same color.
