Hello the (quiet) list, Here i post my current patch queue: - option to disable the optimizations - (visual) enhancements to the curve widget - luminance curve for int/float/sse/3dnow (at last) - bugfix in the preference panel
Some questions i have so far: - on my amd64 the 3dnow code as of SVN just crashes... is this known ? - 3dnow code uses pf2id which truncates floating values, my patch adds 0.5 before truncating. This acheives proper rounding that is used in float/sse. Were you aware of this ? Some caveats in the luminance curve: - int/float/sse work perfectly, however the 3dnow version seems to be buggy at the moment, the image colors are not modified the way they should be, even w/o the curve applied... i've spent too much time reading the code again and again, the 0.5 bias doesn't explain the results i can see. Try #undef USE_3D_NOW_LUMINANCE_CURVE in rs-color-trnsformation.c to see that the curve code isn't really responsible for that yellowish color... Have fun with the patches. -- Edouard Gomez _______________________________________________ Rawstudio-dev mailing list [email protected] http://rawstudio.org/cgi-bin/mailman/listinfo/rawstudio-dev
