I think the problem in your EwLoadExternBitmap() implementation is the color conversion from your source color format into this Alpha8 format. Correct?
correct, we trying for the same.
Can we have any similar example for acessing an external image with Alpha8 properties??
unfortunately, there is no similar example - but it should not be a big thing to change the color copy loop from 4 bytes RGBA to 1 byte alpha.
The question is still what you want to do:
Do you have a source image that contains an alpha channel (e.g. some RGBA format) or do you have an image without alpha channel and you want to convert that into some gray values that should be used as alpha values?Can you share an example of what you have and what you want to get? Then it should be possible to find a solution....Best regards,Manfred.
