    Default v4.23: colors screwd up when resizing a raw image

    Irfanview Version: 4.23
    OS: XP Pro - SP2

    2 bugs in handling of raw images found.

    Procedure:
    - Open a RAW image (8bit per pixel, greyscale, no header)
    - resize image
    1. bug: color changes to 24bit/pixel
    - decrease color depth to 8bit to undo 1. bug
    - save image as a RAW image
    - open image
    2. bug: the colors are completely screwed

    A raw image can be generated by taking a binary PGM image
    and removing the header in a hex editor.

    Thanks,
