Can't get previews of RAW files such as DNG, NEF, CR2, etc

[bigmo]

Please help, 2 days on this and still no results:
I'm just trying to generate previews for my RAW files and all i get is
a generic icon.
Here's my config.php -- what am i missing here? my installation check
says everything is OK.
Many Thanks!

You need to install either ufraw or dcraw, depending on which
raw processor your particular build of imagemagick is set up to use.

I already have ufraw installed. how do i configure imagemagick to use it.

Many Thanks!

[Tom Gleason]

check your /usr/lib/ImageMagick-x.x.x/config/delegates.xml file to see if your ImageMagick wants dcraw or ufraw.
path may vary, but you need to find delegates.xml in ImageMagick config to verify that it's set up to use ufraw.

[DJ Molicious]

Great, first I'd like to say Thank You. I did check the delegates.xml file and it says that it's using ufraw-batch. i then look for ufraw version and i have version 0.17 installed:

$ ufraw --version

Xlib:  extension "RANDR" missing on display "/tmp/launch-vgrqHw/:0".

ufraw 0.17

EXIV2 0.19

JPEG enabled.

TIFF enabled.

PNG enabled.

FITS enabled.

ZIP enabled.

Then i did a test with ufraw-batch and a DNG file and it did output a PPM file so i'm assuming it's working properly. But RS still fails to generate previews for my raw files. I really don't know what i'm doing wrong at this point. Any help would be greatly appreciated.

$ ufraw-batch /Users/me/Desktop/335.dng

ufraw-batch: Loaded /Users/me/Desktop/335.dng 

ufraw-batch: Saved /Users/me/Desktop/335.ppm 

Many Thanks!

what platform?

Test imagemagick "convert" on your raw files.

Also I'd like to see your delegates.xml file out of curiosity.

I don't have MacOSX so I can't really say. You may have to refer to the imagemagick forums for help on this.

Here's my delegate.xml file:

  Delegate command file.

  Commands which specify

    decode="in_format" encode="out_format"

  specify the rules for converting from in_format to out_format These

  rules may be used to translate directly between formats.

  Commands which specify only

    decode="in_format"

  specify the rules for converting from in_format to some format that

  ImageMagick will automatically recognize. These rules are used to

  decode formats.

  Commands which specify only

   encode="out_format"

  specify the rules for an "encoder" which may accept any input format.

  For delegates other than ps:*, pcl:*, and mpeg:* the substitution rules are

  as follows:

    %i  input image filename

    %o  output image filename

    %u  unique temporary filename

    %Z  unique temporary filename

    %#  input image signature

    %b  image file size

    %k  input image number colors

    %m  input image format

    %p  page number

    %q  input image depth

    %s  scene number

    %w  image columns (width)

    %x  input image x resolution

    %y  input image y resolution

  Set option delegate:bimodal=true to process bimodal delegates otherwise they

  are ignored.

Can anybody help me on this please. I can't even test ImageMagick. I keep on getting "command not found". I installed ImageMagick with MacPorts and it's /opt/local. can anyone walk me through testing it to see if it works properly.

Many Thanks!

[DJ Molicious]

OK, I think I'm getting somewhere. I did 2 test to try to convert my RAW files to JPG and another one converting a JPG to PNG and here's my test results: Can anybody please help me configure ImageMagick to use Ufraw as delegate properly? Thanks a Million!
