IM 6.6.3-0 : error message using convert & GIF file

[elendil]

Hello,

i have a bug using IM 6.6.3-0 (linux Fedora 13) on a GIF file, here is what the command return :

Code: Select all

# convert sample.gif sample.jpg
convert: no decode delegate for this image format `sample.gif' @ error/constitute.c/ReadImage/532.
convert: missing an image filename `sample.jpg' @ error/convert.c/ConvertImageCommand/2970.

The same command with a IM 6.4.2 on the same GIF file works fine and produce a JPG file.

Here is the configure command output :

  CXXFLAGS        = -pthread

but when i list the supported formats once the IM 6.6.3-0 install is completed

Code: Select all

# identify -list format | grep JPEG

will only print

Code: Select all

           see part 5 which describes the image encoding (RLE, JPEG, JPEG-LS),
           and supplement 61 which adds JPEG-2000 encoding.

while i got this on the IM 6.4.2

Code: Select all

                 see part 5 which describes the image encoding (RLE, JPEG, JPEG-LS),
           and supplement 61 which adds JPEG-2000 encoding.
      JNG* PNG       rw-   JPEG Network Graphics
      JPEG* JPEG      rw-   Joint Photographic Experts Group JFIF format (62)
      JPG* JPEG      rw-   Joint Photographic Experts Group JFIF format
    PJPEG* JPEG      rw-   Progessive Joint Photographic Experts Group JFIF

So even though the configure command tell me that the jpeg support is enabled (--with-jpeg=yes => yes) and though i installed the libjpeg as mentionned in the Install-unix.txt file, the jpeg does not seem to be supported (or may i have forgotten some thing ?).

One more thing is that if i open the file sample.gif file with Paint.net and do "save as" to another GIF file, this time the new file coming from Paint.net can be converted with IM 6.6.3...

Any idea greatly appreciated

Thanks !

sounds like a corrupt gif. try posting a link to the forum and let others examine it.

Hi,

thanks for the response, here is a direct link to the image :
.

I forgot to mention that both install of IM, 6.6.3 that cannot convert the file and 6.4.2 that can, are installed on 2 distinct servers. The first in installed on a fedora 13 and the second on a CentOs.

i have a bug using IM 6.6.3-0 (linux Fedora 13) on a GIF file

That is a JPG file. So, you have the wrong file ending.
(On my system with IM v6.6.3-9 Q16 on Windows XP, your file can be decoded/converted even with the wrong file ending - but the behaviour in such a situation seems to be different on some IM installations.)

[elendil]

ok, i'm a little bit confused i should have checked files at least

I installed IM 6.6.3-9 and everything is running well now

thanks for the response !
