Legacy ImageMagick Discussions Archive

Now I am really confused. I used a blank folder and reran all the images so they did not have to overwrite and the same images are wrong again! They look nothing like the originals and when I do it as a one off it works just fine! Where could it be getting those images?

Is it possible that the file system has so many images that it cannot keep up with your processing? Have you tried putting a delay between processing of each image?

Could try that. However it does not explain the images that are there. They do not exist on the file system in the first place. Can image magic read the "deleted" images data on the file system? Windows Server 2003 R2.

Does IM have a temp area it could be holding onto images in?

Any tmp is only used during IM processing (usally /tmp)

between commands nothing is retained, unless you specifically write the image yourself.

So it's me again. Just had some more images pointed out to me that fit the discribed issue that we had over a year ago. I don't know how to fix this. If I can write to a clean directory and have these images come up wrong then how can I fix this? I was thinking of added a delete to it first, but since it is doing it on new images then that will not help... This is so weird.

You can have ImageMagick write to a temp area directly. I do this all the time in scripts.

the key however is insuring your scripts 'temps' get properly cleaned up and removed when the script is finished with them.
AND your scripts temps do not interfere with those of a second run of the same script at teh same time.

For solutions look at the IM Examples script...
http://www.imagemagick.org/Usage/scripts/multi_crop
which needs one temporary image file.

Or if you are generating lots of temporary images look at
http://www.imagemagick.org/Usage/scripts/de-pixelate
which creates a temporary directory just for that script.

Both uses shell 'traps' to automatically clean up on shell exit (or error).

So I am copying to a temp directory and sending error to a log. When ti is succesfully resizing and copying the images I get this???

convert.exe: unable to open image `/': Permission denied @ blob.c/OpenBlob/2480.
1 file(s) copied.

Well opening a directory, especially the "/" root system directory does not work very well!

Looks like some of your input arguments have gone screwy or has unexpected spaces, or quoting problems.

If I see the above I start to think I have something like "$dir/$file" and for some reason both variables were miss-spelled or undefined, so the get replaced with blanks. producing "/" which is nonsensical!

Thanks. From another post I found it appears it doesn't like the spaces. However, the script runs fine! So I'm ignoring this for now. No sense in uninstalling ImageMagick and reinstalling for the fun of it...
