93385fddfa Made background loader thread count dynamic, based on processor count. If there are >=4 processors, one processor is spared for snappy parallel image editing. 2010-10-29 09:19:18 +02:00

37ea6a7380 Using Steves threadsafe DCRAW to roughly double thumbnail generation speed on multicore CPUs. Now there are two update worker threads. Easy to remove if someone provides code for a more efficient distribution mechanism. 2010-10-28 21:47:52 +02:00

926056c2c2 Changes to black compression and saturation controls. Black compression from 0-50 acts the same as 0-100 on the previous version, compressing dark tones without crushing blacks. 50-100 then starts crushing blacks until by 100 on the slider, all tones up to the set black point are sent to zero. In the new saturation control, negative values of the slider set a linear curve rather than an inverted S curve, and smoothly decrease saturation to zero across the board. 2010-10-26 22:59:18 -05:00
