Registering a color as transparent?

[soulphalanx]

is there a way for lua to make sprites with a fushia background be displayed with the fushia part as transparent?

u can make a function that reads each pixel one at a time and put it to new image, but if its a certain color (in this case pink) dont draw it. thats the only way that i kno of. theres a post around here with the code, just search for it.

i dont see why you would need to use the pink tho, just make the pink part of the png transparent to begin with.

i have about 500 sprites with fushia backgrounds and i dont want to open every single one of them and make it transparent

is there a way to do this passively?
cause it takes a long time to load the images with function that reads each pixel and creates a new image

or is there a windows program that converts a color in an image to transparent?

paint shop pro has powerful scripting features.. you could probably write a python script to do it in 10 minutes.

Yes, Lua Player can save PNGs, the Windows version, too.
