bitblt unanswered question!

[Aecaiah]

in all of the bitblting tutorials ive read, it make a sprite with you need the original bitmap and another one which acts as a mask, having the black parts = original colours and white parts = transparent....

What ive been wondering is, where does the mask come from?! Do you have to make it yourself?? Say, in a graphics program, paint all the sections u want to be transparent to white and all the parts you want kept to black??

tutorials never answers this basic question..

When I used bitblt I always made them myself and I don't think there's a program to do it for you ^_^

Of course Usako..

I once made that Mask Generator that creates the masks you need.. but in the meantime I directly create the masks in my bitmap handler module when loading them so I dont need the masks anymore *shrugs

I think I posted the program here.. however, Ill post again when i get home.

Works pretty good, although that one uses a relatively slow method if I'm correct.....but hey, I didn't need realtime masking, so why bother trying

Also allows you to combine the sprite and mask into one picture, either horizontally or vertically...

Here's mine.. has some more options and looks a bit different

the split option is nice
but where is the mask color picker?
