Need Help Urgently: Convert CR2 to png

Post by techdev »

Hi All,

I have an urgent requirement to convert CR2 file to PNG. I have installed ImageMagick and Libraw command line tool on my linux server (application scope installation as i don't have root privilege).

Installed ImageMagick and Libraw at : /ngs/app/acto/usr/ --> which has all bin, lib and include files present in folders.

After installing libraw, i have changed my delegate.xml as below:

<delegate decode="dcraw8" command="/ngs/app/acto/usr/bin/simple_dcraw -v -w "%i" mv -f `basename "%o.ppm"` "%o""/>

and when i am trying to run below command :

/ngs/app/acto/usr/bin/convert dcraw8:Scout.CR2 Scout.png

i am getting error message as below:

Processing file /tmp/magick-18357-HDHHBvK1Wr6
Writing file /tmp/magick-18357-HDHHBvK1Wr6.ppm
Processing file mv

Please help.

I do not know much about DCRAW and CR2 images, but it might help to identify your IM version, platform and provide the input CR2 image.

It looks like you are missing a semicolon:
-w "%i"
Should be:
-w "%i" ;

Thanks for quick response. Please find below detail as required
Version : ImageMagick 6.8.6-10 2013-10-05 Q16
Linux Version : Linux version 2.6.32-300.11.1.el5uek (mockbuild@ca-build56.us.oracle.com) (gcc version 4.1.2 20080704 (Red Hat 4.1.2-50))

I updated the delegate.xml with semicolon and now getting below error :

<delegate decode="dcraw8" command="/ngs/app/acto/usr/bin/simple_dcraw -v -w "%i"; mv -f `basename "%o.ppm"` "%o""/>

Error :

Do you have access to /tmp ? You should also change 'basename "%o.ppm"' to 'basename "%i.ppm"'.

<delegate decode="dcraw8" command="/ngs/app/acto/usr/bin/simple_dcraw -v -w "%i"; mv -f `basename "%i.ppm"`. "%o""/>

might it be that you do not have write permission from IM to /tmp?

Out of interest did you try converting a CR2 file before making any changes to your setup?
I am able to convert CR2 files with the standard installation.

Have you tried converting any other file formats?

I am setting this up first time on my development server and unfortunately i don't have root privilege therefore installed Imagemagick and libraw in application scope.

Can you please verify below :


<delegate decode="dcraw8" command="/ngs/app/acto/usr/bin/simple_dcraw -v -w "%i"; mv -f `basename "%i.ppm"`. "%o""/>

Red color command is converting file into ppm at /tmp location (which i can see)
Blue color command is moving/converting ppm file to output (png format)

I dont think there should be 'dot' in between and second once after converting file to ppm, i am trying to move/convert ppm file from my current directory (where actually its not present). Can any one tell me how this command works

Probably not relevant, but shouldn't there be a space on both sides of the ";"?

I just setup same code to different machine with root access :

I have ImagMagick and dcraw installed there as root. Shouldn't be this working now :

<delegate decode="dcraw8" command="/opt/local/bin/dcraw -v -w "%i" ; "%o.png""/>

Are you using dcraw or dcraw_simple? They have different command line arguments. The windows delegate for dcraw is specified like this:

Code: Select all

"dcraw.exe -6 -w -O "%u.ppm" "%i""
//Your command should probably be this:
"/opt/local/bin/dcraw -6 -w -O "%u.ppm" "%i""

<delegate decode="dcraw8" command="/opt/local/bin/dcraw -6 -w "%u.ppm" "%i""/>

Command : convert dcraw8:test.CR2 test.png

Error :

You are missing the '-O' option.
