I've had a few questions from folks who aren't entirely clear how to use ColorFix between "non-default" color spaces.  Here's how to do it.

1. Create a syntax file that describes the input color space and/or the output color space.  For example, say you want to convert from the DiMage color space to BruceRGB.  Because ColorFix's default input color space is the DiMage color space, you don't need to create an input syntax file that describes it.  But, you do need to create a syntax file to describe your desired output color space, i.e. Bruce RGB.  The appropriate syntax is described in the inCfg.txt and outCfg.txt files that are distributed with ColorFix.  All you need to do is find the appropriate parameters, and fill them in accordingly.

An even easier way of creating a syntax file is to use Graeme Gill's ICCDump command-line/DOS utility (http://web.access.net.au/argyll/color.html).  Use a command similar to the one below to "dump" the contents of an icc profile into a text file.  ColorFix is written so that it understands the text files created by the ICCDump program using the -v3 flag:

	iccdump -v3 brucergb.icc > brucecfg.txt

Folks who aren't comfortable using DOS applications may find this command mysterious.  Its fairly simple though.  It runs the ICCDump program, reads the Bruce RGB profile and the writes the output to a text file named brucecfg.txt.

2. Now you've created a text file containing the output color space you can use it with ColorFix (run from the command prompt) using a command like the one below:

	colorfix -obrucecfg.txt myImage.jpg

This command runs colorfix, and converts myImage.jpg from the DiMage color space to Bruce RGB color space (the -o switch specifies the output color space, -i can be used to specify an input color space).

3. You can also use this output space from within ColorFix's Windows program.  In the preferences screen, add "-obrucecfg.txt" as an extra command line argument.

I've also included a minimalist version (i.e. all unnecessary text has been removed) of the brucecfg.txt file that I created at the bottom of this message.  If all else fails, you should be able to copy and paste it into a text file and use it with ColorFix.
