Empty txt: infinite loop

[snibgo]

When x.txt contains ...

Code: Select all

# ImageMagick pixel enumeration: 0,1,65535,srgba

... ie no pixels at all, the command ...

Code: Select all

convert x.txt x.png

... goes into an infinite loop, eating more and more memory. I suppose it would eventually crash. I suggest a quick fatal error would be more graceful.

We can reproduce the problem you posted and have a patch in ImageMagick 6.8.8-5 Beta, available by sometime tomorrow. Thanks.
