Whenever I try and use an animated image I receive this message when trying to output:

Exception 445: unable to persist pixel cache `/home/studio/public_html/ImageMagick/MagickStudio/workarea/d222e15e6aad683ec20bd52cc270503a47a1bb8efd8b5a285c9855d5be31674b331d89b5cc3e495c83f72e4538791f31785783f75d4e84e7fd43b921c9c952d4/MagickStudio.mpc' @ error/mpc.c/ReadMPCImage/952:

No such file or directory

Any and all animated images will not output.

+++++Also the variables keep resetting to default while I am trying to line up something annotated.

SOOOOOO frustrated!

I can confirm this error message. I just uploaded a small dimensioned 38 frame animation (gif) and then tried to output it with no processing other than to view it. That same message then appeared.

Using http://transloadit.imagemagick.org/Magi ... Studio.cgi

It works fine for a single frame gif image.

I have had no problem with any png or jpg files, only animated. And the variables keep resetting during annotation. Thanks for the verification - making me crazy!! LOL

Arbor has one core, limited memory, and limit disk. This limits processing to just small images or image sequences. For larger images and image sequence use Transloadit which has multiple cores with plenty of memory and disk.

I had the same error on transloadit as I mentioned above.

If the host can support large images with plenty of cores, memory, and disk, and it still fails-- that's triggered by the ImageMagick security policy. Its designed to prevent denial of service by preventing any one process from consuming too many resources. We can of course increase the security policy limits but to where? Should we permit images with 50 frames, what about 70, what about 50 frames each @ 4K? At some point, when the demand for resources are high, its recommended to install ImageMagick on your own host and effect the conversion there.

Thank you for the information; that must be a new process because I have never had a problem before and I have been using IM since 1998 with my old web-tv and then my desktop - this is a recent problem of just a few months or so. Can you explain "transloadit" and how it is used - I don't remember ever seeing it. Many thanks again.

I am sorry - but I don't understand your last information re: transloadit. I took an image that easily went through IM correctly, prior to this incident.

and it will load, however, if I try and "output" I immediately get the error message. There is absolutely no way to get to the output page to download it in ANY way. The above image came from a previous IM function and I want to update it but it will do everything BUT "output" an animated image - no matter what the size - even a simple glitter patch.

transloadit is the official IM hosted version of MagickStudio and is at http://transloadit.imagemagick.org/Magi ... Studio.cgi

It is the link in the title blurb of this section of the forum (http://www.imagemagick.org/MagickStudio), which is an alias to the link above at transloadit

I still believe something is wrong on transloadit as well. I create a two frame animation of the rose: image as
I loaded it to transloadit, then viewed it, then tried to save it. I did not get a save page. I just got the error page mentioned above. The rose: image is rather small and it only has two frames. So I do not think it has to do with file size or number of frames.

I apologize if I appear thick, but I took another simple ani image to the last link you gave me

http://gollywobbers.net/IM_STATS/stats1 ... cards2.gif

and when I tried to output, the same error message appears. I did NOTHING to the image, only loaded it and tried to output to no avail. Also I noted that the software is moving at a snail's pace compared to past use - I have used the system for years and never had problems like this. The problem doesn't seem to have anything to do with file size or frames as the examples I gave you were all in use at IM previously, ONLY if it is animated. I have used the software at Arbor forever as well as some of the other sites that were available and while there were sporadic problems they were always repaired. NONE of the links I am using are functioning with animated images now. Thanks

I agree. I think it is a bug. The simple example I used above should have worked. Furthermore as you say it is happening at other copies of Imagemagick Studio, so I think it is a software issue.

Yesterday this web site forum was extremely slow and I thought it might be under a denial of service attack.

Nevertheless, lets give the IM developer some time to see what is happening.

Good idea - I doesn't seem like anyone is actually testing the images to understand the outcome. I sincerely believe it is the software because I have used those exact images before without problems, some MUCH larger. I hope it can be resolved as I genuinely love working with images and colors. Happy to know someone else is having trouble also - beginning to think I suddenly went brain dead!! LOL Have a great weekend

We talked with the ImageMagick developers and they said it was a broken left phalange. It should be fixed now. Give it a try.

It pays to be persistent!! It appears to be functioning now. Thank you for your assistance. JoAnn
