Yes you are correct. I pasted the wrong script in. That was the script that works successfully without producing lines. The problem script should be: #!/bin/csh convert -limit map 512MB -limit memory 512MB -limit thread 1 1000.jpg \ -scale '2000x2000' -flatten -quality 85 output/reference.jpg set i ...

I installed ImageMagick 7.0.1-2 on the server this morning and ran several tests of 1,000 images. I'm still seeing images that are produced with lines in them. I tried building it with our standard configure command: ./configure --prefix=/usr --disable-openmp --with-gs-font-dir=/usr/share/fonts ...

After looking through all the replies I noticed this little note. Note, 512MB is very different from 512mb. I also noticed that the sample script is using "MB" and we are using "mb" in our command. So I tried the following 1000 times: convert -limit map 512MB -limit memory 512MB -limit thread 1 1000 ...

Also as a note the other thread involving a line issue (that I mentioned in the original post) was using a convert command with the -limit memory: viewtopic.php?t=16496.

It seems like we may hand found the trigger for the line issue.

It's beginning to very much look limit the "-limit memory" is the issue. I tried increasing the limit and I tried removing -scale and I'm still seeing lines when the memory limit is in the command.

Thanks all for the suggestions. I've run a number of additional tests since my last post. After following the suggestions above and removing pretty much every part of the command and slowly adding it back, I found that everything went fine and I didn't get any images with lines, until the very last ...

I just completed 1,000 converts with the following command: convert -limit map 512mb -limit memory 512mb -limit thread 1 '1000.tif' -scale '2000x2000' -flatten -quality 85 output/testImage$i.tif; Image 86 has a line in it. So, it looks like we're experiencing the issue even when only dealing with ...

I ran 25 iterations of cd cd desktop/test for ((i=0; i<25; i++)); do convert -limit map 512mb -limit memory 512mb -limit thread 1 '1000.jpg' -scale '2000x2000' -flatten -quality 85 test_$i.jpg done cd and no lines? Ok thanks for trying that. Unfortunately 25 iterations is probably not enough. It ...

Ok I ran another batch of images using the suggested ImageMagick 6 syntax and image 121 has a line in it. Here is a link to the problem image: https://www.dropbox.com/s/msvbixa5c0o7j4g/testImage121.jpg?dl=0 Here is the command used to generate the problem image: convert -limit map 512mb -limit ...

I'll experiment with some of the suggested command reformats and see what the results yield.

I still do not see where -size is creating an image. Perhaps I am mistaken, but I have always assumed that -size only creates new images if you follow it with xc:somecolor. Is it creating a fully transparent image of that size for you? Otherwise, I do not think it does anything. Furthermore, you ...

I tried -synchronize but I'm still seeing lines. Ninety images in on the first test batch and four images in on the second batch.

I apologize for the confusion about the command. I copied it out of my bash script and the path/name of the destination file was stored in variables. I have modified the command as suggested but 11 images through the batch I'm still seeing an image with a line through it. Here is the modified ...

We have an issue where a line randomly appears through a jpeg that is scaled down by convert. This problem is some what rare as we have to run 500 to 1000 images through our processing procedure to replicate the issue and each image is scaled down to five different sizes. It doesn't seem to matter ...
