EPT error (Insufficient image data)

[kriks]

Hi,

we've had a new error for 2 times now on some EPS :

Code: Select all

# identify -verbose 121510.eps
identify: Insufficient image data in file `121510.eps' @ ept.c/ReadEPTImage/223.

Code: Select all

opening with gimp or photoshop does not raise any error, and re-saving it seems to workaround the problem


the file is here : http://dl.free.fr/qrf0nOnTc

any idea ?

[magick]

The image is corrupt. It says the postscript image is 680067 bytes but it was in fact 680066 bytes. We'll patch ImageMagick to make this a warning rather than an error.

[kriks]

thanks a lot for this analysis!

we're waiting for the new patched version

[kriks]

Thank you, version 6.6.0-0 seems to work like a charm for us

[kriks]

wow, I spoke too fast.

when using +clip-path on a buggy image, convert will segfault with

convert -density 300 121758.eps -profile Photoshop5DefaultCMYK.icc -profile AdobeRGB1998.icc +clip-path '#1' -fuzz 100% -transparent white -fuzz 0% -strip -format JPEG -compress JPEG -quality 80 -type Optimize -depth 8 -resize 135x120 -flatten 121758.jpg

*** glibc detected *** convert: munmap_chunk(): invalid pointer: 0x00000000027cbfd0 ***
*** glibc detected *** convert: malloc(): memory corruption: 0x00000000027ceb60 ***

it seems that transforming the error in a warning has some consequences on later code (interpreting image headers ?)

Can you please have a look ?

[magick]

Post a URL to 121758.eps. We need to download it and reproduce the problem. We tried your command with 121510.eps and it ran without complaint.

[kriks]

sorry, here it is : http://dl.free.fr/tXL1jDWo5

[magick]

Grab ImageMagick 6.6.0-1 Beta from ftp://magick.imagemagick.org/pub/ImageMagick/beta. It has a patch that should fix the problem you reported. You may need to wait an hour before 6.6.0-1 is available since its building now.

[kriks]

thank you very much, we'll try it tomorrow and will keep you informed

[kriks]

it still crashes, here is the output for the same command on the same file :

[magick]

If you are running under Linux, download and install the RSVG and RSVG-devel RPMS and rebuild / reinstall ImageMagick. That should fix the problem. In the mean-time we'll add a patch to the ImageMagick internal rendering engine to fix the bug you reported.

[kriks]

We already tried to use RSVG but it fails to render some path properly, and if I remember well, the workaround used in this example to transform a CMYK image with a clip-path does not work the same way, so it's safer for us to wait on a bugfix.
(the workaround was found with your help in this topic )

thank you

[kriks]

up

we have now a lot of these pictures with the same problem, even with non "too much old Photoshop" (CS3).

is it possible to correct this ? or should we invest in finding a workaround ?


thanks for your answer

[magick]

Failure for certain images can be a problem in the image file, in ImageMagick, or in one of the delegate libraries. We'll need a URL to a couple of your images that fail. We need to download them and reproduce the problem before we can track the source of the failure.

[kriks]

here are 3 files that fail:

We hope you'll find something
