Re: Comparing the same files results in differences
This is the Ghostscript command used by ImageMagick: "gs" -q -dQUIET -dSAFER -dBATCH -dNOPAUSE -dNOPROMPT -dMaxBitmap=500000000 -dAlignToPixels=0 -dGridFitTT=2 "-sDEVICE=pngalpha" -dTextAlphaBits=4 -dGraphicsAlphaBits=4 "-r150x150" "-sOutputFile=/tmp/magick-IW9e6gXg-%08d" "-f/tmp/magick-eHVqVwOS ...

Re: Comparing the same files results in differences
Anthony,
Thanks for your reply.
However, to be honest, I have no idea how to do so. Would you be so kind and assist me in this case?

Re: Comparing the same files results in differences
So is this a bug in ImageMagick, since the results using GhostScript directly are correct?

Re: Comparing the same files results in differences
Anthony, Thanks for your reply. Obviously, there's no issue when running GhostScript directly. Here's what I've tried: gs -dBATCH -dNOPAUSE -sDEVICE=tiff48nc -r300x300 -sOutputFile=gs_file1.tif logo.pdf gs -dBATCH -dNOPAUSE -sDEVICE=tiff48nc -r300x300 -sOutputFile=gs_file2.tif logo.pdf compare ...

Re: Issue with applying clipping paths
Anthony, Thanks a lot for your explanations. Unfortunately, it does not seem to be current practice to actually consider the direction of paths when drawing. At least, for Adobe Photoshop it does not seem to matter at all. You can draw a path starting anywhere and tell whether this path is to be ...

Change background by applying clipping path
Hi magick, I would like to change the background of an image by applying its clipping path. That is to say that the current image has a white background and a clipping path which describes a part of this image. The resulting image should be the same image containing the image part with the clipping ...

Re: Difference threshold value
Hi Anthony,
Thank you very much for your reply!
I will try your solution. However, I wonder whether this is considerably slower than the current solution...
Kind regards,
Sven

Re: Difference threshold value
Actually it is overlays with red not magenta. As as of some more recent version of IM the overlay tint percentage was change from 90% to 70%. I am not sure when that change however happened as I did not log it at the time (my bad). Hi Anthony, would it be possible to keep this value variable, since ...

Difference threshold value
Hi magick, I'd like to make a suggestion concerning the compare utility. Currently, the comparison of two images works as follows: If all color channels of pixel (x,y) of image A are equal to all color channels of pixel (x,y) of image B, this pixel is overlayed with 90 % white. If only one color ...

Compare with threshold value?
Hi magick, We're using the compare utility intensively and it works flawlessly. If a certain pixel in image A is different from the corresponding pixel in image B, the resulting pixel in image C will be overlayed with 90% magenta. Now, we're wondering, if it is possible to consider a certain ...

Option -metric outputs to STDERR
Hi magick, the documentation says (http://www.imagemagick.org/script/command-line-options.php#metric) that the option -metric AE outputs to STDERR. I wonder, why it does not output to STDOUT. Well, of course it's the error count of the number of different pixels, but it makes it difficult to only ...
