Houps Right, must be removed

Code: Select all

    .ChangeColorDepth AX_To16Colors 'Change color depth
And this produces a black image! In fact from my experience, the command ChangeColorDepth almost always produces a black image when displayed in a picture box with GetPicture, and almost always only produces the correct effect when its output is written to a file with the SaveBitmap command. It has to be converted BACK to 24bpp with a second use of ChangeColorDepth after lowering the color depth to the desired value with the first use of ChangeColorDepth, if it is to be correctly viewed directly in a picture box. Yet another bug it seems you'll have to fix.
Ok, i'll test. Perhaps it's a problem with the colormap...
