Hi,

Currently it's not possible to opacity blit using two surfaces. The PutPixel method may work, but is slow. I recommend not using it in time critical situations.

Hi,

Please refer to my previous reply. This is currently not possible, but will be added to one of our future releases.

Hi Villy,

For fonts we recommend using RGBA surfaces and make your characters white. Then you can use the EFX_COLORFILL effect to draw fonts in several colors.

Hi Villy,

Yes, right now it's only possible to use RGBA. Do you have all the characters in a sheet, or do you generate them one by one as you draw? The first method may be better for performance.

Yes I use dynamically created surfaces for several letters.

How may time you need to add AlphaBlt from 2 surfaces feature to EDGELIB ?

Of course I can make my own function for this but I spend a bit more time for this then you. And It's harder to explain to my boss why we need to buy EDGELIB
