This year at WinHEC we had a demo that showed the use of ICC and WCS by various applications and system components on Windows Vista. A part of this was a specially prepared jpeg image with an embedded ICC profile that contains a WCS profile in an ...

I recently noticed a discrepancy between the online documentation for the WcsOpenColorProfile and OpenColorProfile APIs and their declarations in the icm. h header file (and the icm.h version is correct). The Windows Vista SDK online documentation at...

One of our IHV partners (thanks, Harold!) recently asked a question regarding the IDeviceModelPLugIn::DeviceToColorimetricColorsWithBlack() API in the WCS device model plugin interface (see http://windowssdk.msdn.microsoft.com/en-us/library/ms536863.aspx...

The Color Team is pleased to announce that, as promised, we have published our internal design specifications for WCS. These detail all of the algorithms used in the WCS baseline device models and gamut mapping methods. They now part of the Windows Vista...

We've had a couple of folks tripped-up over this issue, so I figure it's worth a blog posting. Early versions of the WCS documentation indicate that none of the ICM APIs that deal with specific ICC profile structures will work with WCS device model profiles...

The number of questions we've seen regarding this issue indicates that there is still some confusion out there... So, I'm going to interupt the WCS gamut mapping series to clarify things: WCS will not be available for any pre-Windows Vista OS platforms...

The WCS Minimum Color Difference (MinCD) baseline gamut mapping model is conceptually the simplest of our gamut mapping algorithms. It corresponds roughly to the ICC colorimetric rendering intents, and like them it comes in two flavors that roughly correspond...

Gamut mapping in WCS is established at color transform creation time, rather than at profile creation time. And, while our baseline gamut mapping methods each implement a different gamut mapping algorithm, there are some operations that are common to...

Until recently, most ICC-based color management processing engines (CMMs), including Windows' ICM CMM, implemented the processing models defined in the ICC profile format specifications; they were a collection of matrix and interpolation table processors...

Predictability is often cited as the most desired and valuable characteristic of a color managed workflow. It's also been one of the most difficult to achieve. A widely recommended approach involves sticking with a single CMM (Color Management Module...

Back in November of 2005, I presented an invited paper on the Windows Color System (WCS) at CIC 13 in Scottsdale, AZ. The annual IS&T/SID Color Imaging Conference is the world's premier color science conference, and draws distinguished color scientists...
