running dcraw plugin

[Thu Tran]

Hi all,
   
  I am hoping for any suggestion which you may have for me...
   
  I am trying to instal and consequently run the dcraw plugin but am
having problems getting the plugin to run.
   
  When I select Plugins->Input/Output->DCRAW Reader I get an
"Exception" appearing with the following cotents:
   
  java.lang.UnsupportedClassVersionError:
net/sf/ij_plugins/dcraw/DCRawPlugin (Unsupported major.minor version 49.0)
   at java.lang.ClassLoader.defineClass0(Native Method)
   at java.lang.ClassLoader.defineClass(Unknown Source)
   at java.lang.ClassLoader.defineClass(Unknown Source)
   at ij.io.PluginClassLoader.loadClass(PluginClassLoader.java:234)
   at ij.io.PluginClassLoader.loadClass(PluginClassLoader.java:199)
   at ij.IJ.runUserPlugIn(IJ.java:270)
   at ij.IJ.runPlugIn(IJ.java:116)
   at ij.Executer.runCommand(Executer.java:88)
   at ij.Executer.run(Executer.java:46)
   at java.lang.Thread.run(Unknown Source)
   
  Could anybody please help?
   
  I am running ImageJ v1.37c, Java v1.4.2 on a Windows XP computer?
   
  Thank you.
  Thu Tran

An UnsupportedClassVersionError means that the class was compiled with a
newer JDK than the current one.

Two possible solutions:

- recompile with your JDK, or
- upgrade your JDK.

(The first is faster, while the latter is easier).

The updated release of DCRaw Reader plugin fixes the problem; it was
recompiled to be back compatible with Java 1.3 and newer. Also the
native binaries for Linux and Windows were updated with dcraw v.8.13.

Hi,

I just tried it out on raw data from my new Sony DCS-R1.  It works!  
That is great, thanks for making this available.

So the question is: where are you going with this?  I don't know
anything about dcraw and will start looking into it, but there are lots
choices to be made when converting raw data, not to mention trying to
reverse engineer the magic settings of the various manufacturers.

I am new to the digital raw world, but it seems a real can of worms to
me.  Each manufacturer has its own proprietary raw format, and does not
disclose the various white balance curves, contrast curves, sharpening
algorithms, noise reduction algorithms, etc that they use.  I see that
there are a bunch of raw conversion programs out there with Adobe Camera
Raw (a plugin to Photo$hop) in the lead.  What a headache these poor
guys have trying to keep abreast of all the new cameras.

Sony gives away a program to read its raw files, but the program is slow
and appears to be disliked by users.  It seems stuck at version 1.0. Why
Sony cares to create a proprietary format for its raws and then doesn't
make the effort to create a good reader is a mystery to me.

The intention of DCRaw Reader plugin is to simply provide a convenient
way of using the dcraw binary by Dave Coffin. Not planing to add any
camera specific functionality that is not in dcraw. Currently only the
most basic dcraw options are supported by DCRaw Reader plugin. Support
for more dcraw options may be added in the future.

There is also a pure Java project at https://jrawio.dev.java.net/ that
helps reading raw images using javax.imageio. It works with with ImageJ,
to some extent, using the Image IO plugin bundle v.2
(http://ij-plugins.sourceforge.net/plugins/imageio/).  I was able to
read with jrawio and ImageJ raw image from Canon Rebel XT, but not from
Canon D60, did not try other formats. Note that Image IO plugin bundle
v.2 is in alpha stage and not release yet, you will need to build it
from CVS source.

Once you use DCRaw to get the linear image you could do most of the
other transformations using ImageJ, but this is a little slow.

Here is a kludge macro I wrote to take the linear raw and apply a gamma
curve to it then store in 8 bit RGB.  It would be much faster to use a
LUT for the Gamma curve as DCRaw does.

 if (nImages==0) {
open();
   }

stack = getImageID;
selectImage(stack);
var x=0.5;
x = getNumber("Gamma", x);
setSlice(1);
run("Duplicate...", "title=R");
run("Gamma...","value="+x);
selectImage(stack);
setSlice(2);
run("Duplicate...", "title=G");
run("Gamma...","value="+x);
selectImage(stack);
setSlice(3);
run("Duplicate...", "title=B");
run("Gamma...","value="+x);
//run("RGB Merge...", "red=R green=G blue=B keep");
run("RGB Merge...", "red=R green=G blue=B");
