I'm looking for a fast way to apply an alpha value to the entire image during display only. In GDI+ I used a color matrix for this. Is there anything similar for IRasterImage?

Thanks,

Chad

Chad,

We don't actually have function to do this for display-only. You can
create a second bitmap by combining the original bitmap with a
background bitmap using a specific opacity value with the
AlphaBlendCommand Class. You can then use the resulting bitmap for display.

Thanks,
