im using al_draw_tinted_scaled_rotated_bitmap_region to draw 128X128 sprites, can be in various scales, I can draw the whole image transparent, easy enough, or use drawadd i think it was, but niether does what I would like. Is there anyway, that I can only draw the outter pixels translucent, basically anti alias the image.

I can think of a way to do it, programatically split the image into 2, cut off the edges of the sprites, store them in a second image, then when I draw the sprite, I draw the one with the edges cut off solid, then draw the one that had the edges translucent. If it was all done before hand, that would have little impact on performance. But is there a simpler way to anti alias a sprite JUST for al_draw functions???

Thanks for the reply, I had considered that approach, but the sprites are quite detailed, and odd shapes, so drawing the sprite a bit bigger in the back ground may look odd, I will have a play with that mind you. What I am try to achive, my sprites have sharp edges, when they were rendred, it darkened the edges, its ok as it is, but I would like to soften them, I could programaticaly go through the sprite and lower the outter pixel colours a bit. Or what I was thinking was best, is as its drawn to the screen, it would be nice if it blended the outter line of pixels with whatever pixels were beind them, that should soften them I hope.

You could create your images as a .png with an alpha channel I guess; set the outer 1 or 2 pixels to be 50% transparent on the channel, and then just render them...I could be wrong of course.
