Hi,

For your effect we recommend using RGBA surfaces. Store the image with your transparent pixels in a PNG and load it on a E2DSurfaceRGBA. You can also load your current image, and use replacecolor to replace black (rgba: 0, 0, 0, 255) to black with 50% transparency (rgba: 0, 0, 0, 128).

Thanks for your reply. Using RGBA surfaces, of course, the obvious option. But I was hoping to use RGB surfaces, because they support the scaling and rotation. But if this is impossible, I have to use RGBA surfaces.

Hi,

Thanks for your reply. You offered a good solution but my sprites already contain areas marked as a shadow using some color.
