I load image from png file to surface. It have some transparent parts. Then i create a texture from surface and drawing it with render. How can i check if mouse cursor is over transparent pixels of this image? With old version of SDL (1.2) it was simple. We had surface and function SDL_GetPixel(), checking alpha value with threshold and all is works. But with new version we have texture, and surface needed to be cleaned, because wasted a lot of memory. How can i determine the mouse cursor is over the visible part of the image? Is there simple solution? _______________________________________________ SDL mailing list [email protected] http://lists.libsdl.org/listinfo.cgi/sdl-libsdl.org
