IM 7.0.8-16 - Problem with mpr: index numbers

[GeeMack]

Using ImageMagick 7.0.8-16 Q16 x64 HDRI on Windows. There seems to be a problem accessing an "mpr:" memory register by index number. When running this command...

Code: Select all

magick -size 32x32 xc:red xc:lime xc:blue -write mpr:test -delete 0--1 mpr:test[0] out.png

... the output should be a single red square read from "mpr:test[0]". Instead it outputs all three images, the red, lime, and blue. The same failure occurs when using any combination of index numbers inside the square brackets like "mpr:test[N]", "mpr:test[N-N]", "mpr:test[N,N]". The output in every case is all the images that were written to the "mpr:". There are no errors or warnings, even if using an index number beyond the number of images in the "mpr:" list.

I get the same behavior on IM 7.0.8.16 Mac OSX Sierra. It also fails on IM 6.9.10.16 Q16 for me.

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 @ https://www.imagemagick.org/download/beta/ by sometime tomorrow.
