spritesheet:compile getting convert: unable to open image 'canvas:transparent'

[souprmage]

I've inherited a project using Node.JS that I'm trying to compile, but I get an error when running spritesheet:compile. The version of ImageMagick is 6.5.7-8.

It seems like my convert version doesn't support the command that's attempting to be run by spritesheet:compile.

Should this version of convert work? Is there a minimum version I need to get this to work?

Is there something I can do to track down why this parameter is being interpreted to be a file name?

This is because imagemagick.coffee uses the new-ish alias canvas:transparent instead of the longer-supported xc:transparent. Convince @richardbutler to change line 35 and it'll work, or upgrade ImageMagick.

Discussion here.
