    Masking a bitmap

    I am attempting to the background in my bitmap and I seem to cannot get it to work. What must I be doing wrong here?

    Here's what I did, I captured my baseline image (bitmap1).
    Window1.CaptureBitmap (bitmap1.bmp, r)

    then
    SYS_CompareBitmap (bitmap1, bitmap2)

    the difference between bitmap1 and bitmap2 is just the background. i run the bitmap tool to get the difference. after i got the difference, i converted it to a mask. saved the mask to mask1.

    then i used mask1
    SYS_CompareBitmap (bitmap1, bitmap2, mask1) but still it fails the comparison.

    what must i be doing wrong here?

    Re: Masking a bitmap

    You're doing everything right, it sounds like. Try recapturing the bitmaps and recreating the mask file. Make sure you capture all of the bitmaps on the same machine at the same resolution.

    Hope this helps.
