Hi!

Thanks for the great work on Digikam etc!

Please could you give me an indication of when the RAW files from my lovely new Canon EOS 550D will be supported? I see that a new version of dcraw.c is around at http://sourceforge.net/tracker/index.php?func=detail&aid=2970192&group_id=127649&atid=709089 that already supports the 550D.

Thanks again,

I would suggest filing a bug report at bugs.kde.org about this, so that the Digikam developers are aware of this and can update libkdcraw.

Here is a recipe that worked for me - digikam now opens Canon RAW files ( .cr2) from my EOS 550D in Image Editor

Just one file needs modifying from svn version of digikam that I downloaded on 18th March 2010 as described at http://www.digikam.org/drupal/download?q=download/KDE4

Download the latest kdegraphics libs:

Code: Select all

# svn co -N svn://anonsvn.kde.org/home/kde/trunk/KDE/kdegraphics
# cd kdegraphics
# svn up libs
# svn up cmake

Edit the file kdegraphics/libs/libkdcraw/libraw/internal/dcraw_common.cpp at line 6958 by inserting the following snippet (from the latest dcraw.c from http://sourceforge.net/tracker/index.ph ... tid=709089) :

Code: Select all

 } else if (is_canon && raw_width == 1336) {
    top_margin = 51;
    left_margin = 142;
    raw_width = width *= 4;
    if (unique_id == 0x80000270)
      adobe_coeff ("Canon","EOS 550D");
    goto canon_cr2;

so that it now reads:

Code: Select all

  } else if (is_canon && raw_width == 1280) {
    height -= top_margin = 45;
    left_margin = 142;
    raw_width *= 4;
    width = 4916;
 } else if (is_canon && raw_width == 1336) {
    top_margin = 51;
    left_margin = 142;
    raw_width = width *= 4;
    if (unique_id == 0x80000270)
      adobe_coeff ("Canon","EOS 550D");
    goto canon_cr2;
  } else if (is_canon && raw_width == 1340) {
    top_margin = 51;
    left_margin = 158;
    raw_width = width *= 4;
    goto canon_cr2;

Build kdegraphics:

Code: Select all

# mkdir build
# cd build
# cmake -DCMAKE_BUILD_TYPE=debugfull -DCMAKE_INSTALL_PREFIX=`kde4-config --prefix` ..
# make
# sudo make install

Download and build the latest digiKam and Kipi-plugins:

Code: Select all

# cd ../..
# svn co -N svn://anonsvn.kde.org/home/kde/trunk/extragear/graphics
# cd graphics
# svn up digikam
# svn up kipi-plugins
# svn up cmake
# mkdir build
# cd build
# cmake -DCMAKE_BUILD_TYPE=debugfull -DCMAKE_INSTALL_PREFIX=`kde4-config --prefix` ..
# make
# sudo make install

Then restart digikam! I hope it works for you!

Have you filed the bug at bugs.kde.org so the Digikam developers can update the svn version?

Yes - I commented on a previous request to update libkdcraw at https://bugs.kde.org/show_bug.cgi?id=225853
