			ColorFix Readme

	
	*****Introduction*****


For the latest version of ColorFix, check: http://tawba.tripod.com/colorfix.htm

ColorFix is a tool to convert the colors in JPEG images from one colorspace to another.  Although ColorFix can be configured to convert between any two color spaces, its default setting is to convert the typically dull colors produced by the Minolta DiMage 5 and 7 digital cameras to something more appropriate (sRGB color space) for viewing on a computer monitor. Unlike most current digital cameras, the DiMage digital cameras capture images using a special, wide "color space" that may not display properly on most monitors using conventional image viewing software. ColorFix converts the colors in these images so that they appear more natural (i.e. vibrant) on a computer monitor. 


Note: ColorFix.exe is a DOS program that can be run from the command line.   CFGui.exe is a Windows application (a "front-end" for ColorFix.exe) that eliminates the need to interact with a DOS window, although ColorFix.exe must be installed in order for CFGui to operate.



	*****Installation Instructions*****

Windows Version (CFGui.exe):

After unzipping the "zip" file, use the setup.exe program to install ColorFix.

IMPORTANT: ColorFix was written using Visual Basic 6 and requires some "helper" (a.k.a. "Runtime") files in order to work properly.  These helper files are freely available, and your system may already have them.  However, If you are unsure or you cannot seem to run ColorFix without an error, download them from the link on ColorFix's page (http://tawba.tripod.com/vb6tawba.htm).

Dos Version (ColorFix.exe):

After unzipping the "zip" file, place colorfix.exe in a directory of your choice.  Type Colorfix.exe -? at the command prompt go get help.

	*****Program Status*****

ColorFix is shareware, meaning you are expected to "register" it (i.e. pay a small fee for it) to purchase the program. While ColorFixx will operate without registration, it is limited to processing images with a maximum size of 1280x960 pixels.  You can register ColorFix on-line using the Kagi payment processing service:
