WriteJPEG Compression

  • Hello,

    For the function WriteJPEG how is the compression parameter used. I have tried it with several different values but my created jpegs are identical.

    I have used several image edition programs that have the concept of Quality on a 0 to 100 scale for Jpegs where 100 percent is the best quality (least compression). Is that the idea here or is it something different?

    Thanks,

    Mark
