being able to statically init a mutex<br> + (actually a Critical Section on windows). Windows has<br> + no official API for statically initing a critical<br> + section, so lcms2 uses a hack (albeit it a safe one)<br> + to do this.<br> +<br> + Unfortunately ApplicationVerifier (and presumably other<br> + similar tools) don't understand this idiom, and get<br> + confused by not seeing an explicit initialisation call.<br> + This is causing problems for a customer.<br> +<br> + This commit therefore introduces code to properly<br> + initialise it on Windows. In order to avoid any possible<br> + multithreaded startup issues, we use the Windows<br> + InterlockedCompareExchangePointer API (introduced in<br> + Windows XP).<br> +<br> + If anyone wants to avoid this code (so they can work<br> + on pre-Windows XP), they can build with:<br> +<br> + CMS_RELY_ON_WINDOWS_STATIC_MUTEX_INIT<br> +<br> + defined, and get the old behaviour. We automatically<br> + set this when building with any version of MSVC older<br> + than VS2005 (i.e. those that don't have that API<br> + available).<br> +<br> +base/lcms2.mak<br> +lcms2/AUTHORS<br>

Previously the<br> + transparency compositor always used CMYK for the blend color space<br> + if the output device was a separation device.<br> +<br> + With this commit:<br> +<br> + If the blend space is RGB or Gray based, then we now ensure that the<br> + alternate tint transform is not used when we encounter a separation or DeviceN color space.<br> + (assuming we have not run out of spot color space at the target device). Note that<br> + if the any of the spot colors in a DeviceN color space are CMYK process colorants and the<br> + blend space is Gray or RGB, the alternate tint transform IS used.<br> +<br> + 2) The pdf14 compositor now handles a mixture of additive and subtractive components.<br> + I.e. RGB + spots or Gray + spots.<br> +<br> + 3) If the blend mode is non white preserving or not separable, then the spot colors<br> + use the normal blend mode while the process colorants use the specified blend mode.<br> +<br> + 4) In the process there was a bit of code clean up.
