composite command - ImageMagick version 7

[kammo]

Hi guys,

Our data centre has just upgraded ImageMagick to:
Version: ImageMagick 7.0.1-2 Q16 x86_64 2016-05-06

I've been using the following command successfully in version 6:

Code: Select all

composite -gravity SouthEast watermark.png wizard.jpg wizard.jpg

...this was overwriting wizard.jpg with a watermarked version

However in version 7 instead of creating the watermarked image it's outputting:
wizard-0.jpg (which is the watermark.png converted to jpg)
wizard-1.jpg (which is a copy of wizard.jpg)

Has the command changed?

What platform?

I would suggest that you use the magick/convert .... -composite structure, which is much more flexible and current. Composite is an old legacy structure even for IM 6. See http://www.imagemagick.org/Usage/compose/#compose

Code: Select all

magick wizard.jpg watermark.png -gravity southeast -composite wizard.jpg

or

Code: Select all

convert wizard.jpg watermark.png -gravity southeast -composite wizard.jpg

You can also try the following. See http://www.imagemagick.org/Usage/compose/#compose

Code: Select all

magick composite -gravity SouthEast watermark.png wizard.jpg wizard.jpg

Thanks for the response.

Platform = Linux Centos 6.7

I just tried with the first 2 commands, but get the same output:
wizard-0.jpg
wizard-1.jpg

When trying magick composite I get this:

Code: Select all

magick composite -gravity SouthEast gray30.png wizard.jpg output.jpg
magick: unable to open image 'composite': No such file or directory @ error/blob.c/OpenBlob/2691.
magick: no decode delegate for this image format `' @ error/constitute.c/ReadImage/505.

Sorry, I forgot the -composite at the end of the first two commands. Corrected above. I have not been successful with the third command and this may be a bug.

Thanks for the problem report. We can reproduce it and will have a patch to fix it in GIT master branch @ https://github.com/ImageMagick/ImageMagick later today. The patch will be available in the beta releases of ImageMagick @ http://www.imagemagick.org/download/beta/ by sometime tomorrow.

The data centre rolled me back to version 6.9.3-10 Q16 so I didn't get a chance to retest with version 7 however, the "convert -composite" command and the original composite command that I was using are both working all OK again with version 6.9.

Many thanks for taking the time to help.
