i m new in programmation basic4gl, and trying to working functions sprites, but there is a big problem. when i do a sprite and call a image .jpg, the blank around the sprite if affiched to!!! so there is not a piece of chess who is printed but a piece of chess like in a block of glace!!!
how erase the blank across the sprite and make it transparent???
i think it must done when the sprite image is create with a painting logiciel but i don't know how...
well, I think I may just understand what you are saying first download this Gimp then in gimp go to layer > transparency from there you can either add alpha channel (when you erase it goes transparent) or color to alpha. after this, do NOT save a .jpg, this file format doesnt support transparency. I recommend, for basic4gl, saving in the .bmp format because for some reason b4gl loads .bmps with transparency better than others (in my experience)
