Not sure what's going on here.


local loadScreen = paintutils.loadImage("testImage.nfp")
paintutils.drawImage(loadScreen, 1, 1)

The error this code produces is 

paintutils.lua:38: attempt to call nil

I understand what attempt to call nil on its own usually means. What's the problem here? I'm trying to apply the same logic but I'm pretty sure my syntax is fine. (Comparing this code directly to the wiki)



Keep in mind.
testImage.nfp DOES exist. It's very real.

Probably not related to the actual error, but paintutils doesn't handle the nfp format.

Hmm. I thought the whole purpose of painutils.loadImage() was to load a previously drawn image using the 'paint' program. Paint produces .nfp files.

Huh, I did not know that. NFP was originally used by NPaintPro which supports more than the default paint program. I retract my earlier statement.

It's a bug in one of the earlier CC1.80 pre-release builds. Update to a later version.
