picturefold error

[pim]

Hello,
I am a absolute beginner with IM.
Just tried two scripts from Fred: stainedglass worked - picturefold dind't

My system:
Ubuntu 18.04 LTS
Version: ImageMagick 6.9.7-4 Q16 x86_64 20170114

And here what I get:
CASE1: no image map.jpg is produced at all...
>> picturefold.sh -n 5 ~/Downloads/birdofparadise/cartoon-parrot.jpg ~/Downloads/birdofparadise/map.jpg
convert-im6.q16: DistributedPixelCache '127.0.0.1' @ error/distribute-cache.c/ConnectPixelCacheServer/244.
convert-im6.q16: cache resources exhausted `/tmp/picturefold_1_3913.mpc' @ error/cache.c/OpenPixelCache/3982.
convert-im6.q16: unable to persist pixel cache `/tmp/picturefold_1_3913.mpc' @ error/mpc.c/ReadMPCImage/963.
convert-im6.q16: no such image `black' @ error/mogrify.c/MogrifyImageList/8770.
convert-im6.q16: no images defined `/tmp/picturefold_1_3913.mpc' @ error/convert.c/ConvertImageCommand/3258.

CASE2: image map.jpg is produced without an error message. However, the output file is just a vertical piece of the input file - the 1/n most left tile f the input file.
>> picturefold.sh ~/Downloads/birdofparadise/birdofparadise.gif ~/Downloads/birdofparadise/map.jpg

Any idea why I observe such a strange beaviour?

Cheers, pim

I can confirm it is not working properly in the current 6.9.9.40 Q16 Mac OSX. I will look into it. Something has changed in ImageMagick. I will get back when I have it fixed.

[fmw42]

OK. I think it is fixed. Download the lasted version from my web site with today's date and try it. Let me know if it now works OK.

Thanx for your reply.
If I use the new script with the birdofparadise.gif as input everything works perfectly.
However, with cartoon-parrot.jpg as input an error messages appears...
Can you help decode the thrown error?

What is your current version of ImageMagick? The new script worked fine for me with the cartoon-parrot2.jpg from my web site on both IM 6.9.7.4 and 6.9.9.40. Do you have enough memory or any restrictions from the policy.xml file? Do other large images fail or just cartoon_parrot.jpg?

[pim]

As already mentioned in my first post:
Ubuntu 18.04 LTS
ImageMagick 6.9.7-4 Q16 x86_64 20170114 -> no changes made after Installation.

• What are the critical entries in the policy.xml file?
• I'll try another large picture in the evening today

[fmw42]

The last update of your script was 20170114 i.e. Jan 14, 2017. So that is about 6 months old. You might check with the Ubuntu distribution people to see if there is a more current update. But your error message seems to imply that cache resources have been exhausted. I believe that this means that you are exceeding some limitation either in your directory limits or your server limits or ImageMagick policy limits.

[pim]

Code: Select all

sudo apt-get upgrade

does not change the version of Imagemagick.

in the /etc/ImageMagick-6/policy.xml file it looks as follows:

Code: Select all

<policymap>
  <!-- <policy domain="resource" name="temporary-path" value="/tmp"/> -->
  <policy domain="resource" name="memory" value="1GiB"/>
  <policy domain="resource" name="map" value="1GiB"/>
  <policy domain="resource" name="width" value="16KP"/>
  <policy domain="resource" name="height" value="16KP"/>
  <policy domain="resource" name="area" value="128MB"/>
  <policy domain="resource" name="disk" value="10GiB"/>
  <!-- <policy domain="resource" name="file" value="768"/> -->
  <!-- <policy domain="resource" name="thread" value="4"/> -->
  <!-- <policy domain="resource" name="throttle" value="0"/> -->
  <!-- <policy domain="resource" name="time" value="3600"/> -->
  <!-- <policy domain="system" name="precision" value="6"/> -->
  <!-- not needed due to the need to use explicitly by mvg: -->
  <!-- <policy domain="delegate" rights="none" pattern="MVG" /> -->
  <!-- use curl -->
  <policy domain="delegate" rights="none" pattern="URL" />
  <policy domain="delegate" rights="none" pattern="HTTPS" />
  <policy domain="delegate" rights="none" pattern="HTTP" />
  <!-- in order to avoid to get image with password text -->
  <!-- <policy domain="path" rights="none" pattern="@*"/> -->
  <policy domain="cache" name="shared-secret" value="passphrase" stealth="true"/>
</policymap>

What seems odd to me is that

Code: Select all

picturefold.sh birdofparadise.gif map.gif

works perfectly fine whereas both

Code: Select all

picturefold.sh cartoon_parrot2.jpg map.gif
picturefold.sh cartoon_parrot2.gif map.gif

do throw the error mentioned in the earlier post.
The size of the files are in the order mentioned above: 123 kB, 29 kB and 109 kB.

Can this really be an problem of size?

What about the error line?

Code: Select all

convert-im6.q16: no such image `black' @ error/mogrify.c/MogrifyImageList/8770.

Errors further down your list are likely due to the error at the beginning. When something fails and it cannot access an image, then other errors can follow subsequently. So the first thing to find out is why it is failing for those images with the issue with the cache.

I would suggest you post a message to the bugs forum and link to this topic. The IM developers would know more than I do about such cache limits and errors.

The input file sizes are not necessarily relevant due to compression or limited colors. What is relevant is how much disk and memory they need once they are read and converted to 24-bit uncompressed color and then how many temp versions my script creates to do the processing (in this case two temp mic files) plus the output.

What do you get if you do

Code: Select all

cd /tmp
ls -al

Do you have any restrictions on your Download folder?

[fmw42]

If you email me directly, I can create a version of the script with echo messages so we can at least track down where in the script it fails. (fmw at alink dot net)

I will write you a pm for a debugging version of the script. Thank you a lot!

[fmw42]

OK. I do not see any large files or left over from ImageMagick.
