Does anyone know of an efficient way to copy a TImage?

Right now, i'm using:

local imageCopy:TImage = loadimage(lockimage(originalImage))

..which diesn't seem very efficient!

thanks

You could load the image file into a pixmap, and then loadimage twice from that pixmap.

i ended up sticking with the method I posted above.. I got to testing it, and even though I'm doing it at full framerate, it hasn't slowed my application down at all, and I'm still maxed at my monitor refresh rate!

if all of your images are of format rgba and of the same size it can be as simple as

MemCopy(DestPixmap.pixels,sourcePixmap.pixels,sourcePixmap.width*sourcePixmap.height*4)

Local imageCopy:TImage = LoadImage(originalImage.pixmaps[frame])

That's about as efficient as you can get.

Are you modifying these copies? Why not just display the original?
