Plasma operator not working

[fabrizio108]

Hello,
I've upgraded from ImageMagick 6.6.1-5 (Q16 Windows x64 Dll) to ImageMagick 6.6.6-1 (Q16 Windows x64 Dll), but I can no longer generate images using plasma operator, i.e. I obtain only blank images.

For example, if I run this script:

cd "C:\Program Files\ImageMagick-6.6.6-Q16"
call convert -size 100x100 plasma:fractal C:\Work\ImageMagick\fractal.jpg

I obtain a 100x100 white image. With 6.6.1-5 release instead the script was running fine.

I also check the manual (http://www.imagemagick.org/Usage/canvas ... _gradients), and the sintax is always the same.

Best regards
Fabrizio

This works fine for me under IM 6.6.6.1 Q16 (hdri) Mac OSX Tiger

convert -size 100x100 plasma:fractal tmp.png

Sounds like the 'plasma:' image coding module is failing. That is a sign that your IM is not installed correctly or has wrong permissions.

Hello, thanks for replies.
I've installed the 32 bit version of ImageMagick and the plasma operator works fine, with the same script.
So I think that It could be a problem of the 64 bit Win package.
I've also done some traces during the running of the convert command (64 bit version) and I saw that IM_MOD_RL_plasma_.dll is succesfully loaded, despite the blank results.

My operating system is Windows 7 64bit.

Best regards

This command:

Code: Select all

convert -size 100x100 plasma:fractal fractal.jpg

also produces only a blank white image on my machine which is now a 64-bit Win 7 Pro using:

Code: Select all
