My stupid fingers deleted a topic instead of moving it to bugs. Sorry about that.
The report was this:
Code: Select all
compare -metric RMSE -subimage-search reso1_res.png settingsReso1_1.png null:
compare: image morphology differs `reso1_res.png' @ error/compare.c/SimilarityMetricImage/1988.
The comparison works fine under 6.8.9-5 on Windows, but fails under 6.8.9-6.
@maxi4: can you link to your sample files again?
Sorry again.

this seems to work fine for me under IM 6.8.9.6 Q16 Mac OSX
Code: Select all
compare -metric rmse -subimage-search mandril3.png mandril3_156_22.png null:
0 (0) @ 156,22
Is there something odd about your input images? Or am I misunderstanding the issue?
Note when using -subimage-search the first image is larger than the second image.

oh, snigbo, don`t worry, that`s ok!
here are files:
image
https://drive.google.com/file/d/0B8qRom ... sp=sharing
sub-image
https://drive.google.com/file/d/0B8qRom ... sp=sharing
yes, i know about image and sub-image order on command line.
Please tell me, can i use legacy IM version, like you?
May be it will work for me..

yep fmw42, ImageMagick 6.8.9-5 has worked:
C:\print_log\script\settingsReso1>compare -metric RMSE -subimage-search reso1_re
s.png settingsReso1_1.png null:
0 (0) @ 5,341
C:\print_log\script\settingsReso1>compare -version

With your images, I get your error message:
Code: Select all
compare -metric rmse -subimage-search reso1_res.png settingsReso1_1.png null:
I created two new images of the same size and it works fine.
Code: Select all
compare -metric rmse -subimage-search \( -size 23x1754 gradient: \) \( -size 16x16 xc:gray50 \) null:
173.114 (0.00264155) @ 0,872
However, it fails, saving the gradient and the gray50 image as png
Code: Select all
convert -size 23x1754 gradient: grad.png
convert -size 16x16 xc:gray50 gray50.png
compare -metric rmse -subimage-search grad.png gray50.png null:
But saving as tif, works.
Code: Select all
convert -size 23x1754 gradient: grad.tif
convert -size 16x16 xc:gray50 gray50.tif
compare -metric rmse -subimage-search grad.tif gray50.tif null:
173.114 (0.00264155) @ 0,872
Looks like it is a PNG issue with very small images, since it worked fine for me with larger PNG images.

Try ImageMagick 6.8.9-7 Beta. Does that resolve the problem?

Yes, for me this now works.
Code: Select all
convert -size 23x1754 gradient: grad.png
convert -size 16x16 xc:gray50 gray50.png
