Bits per channel

Hello,
I have looked online on the Gimp site and I am not clear if Gimp supports 16 or 24 or 32 bit images? Can someone point me to the correct answer for Gimp 2.6.7 Thanks _______________________________________________ Gimp-user mailing list Gimp-user@... https://lists.XCF.Berkeley.EDU/mailman/listinfo/gimp-user |

GIMP 2.10/3.0 will.

GEGL uses 32 bit floating point numbers, that gives 128 bit per coloured pixel (with alpha channel). Using 16 bit integers, the maximum intensity of a color channel is 0xffff. This may lead to temporarily color cropping during multi-step operations, even if the final channel intensity is below 0xffff. By using floating point numbers, no temorarily cropping will occur.

Working with 16 bit per channel images will be great!
16 bits per channel is essential when working with high dynamic range (HDR) images. What is the timeline for 2.10/3.0?

I believe you'll find that you can only get a meaningful timeline for eg. 2.10 after 2.8 is released. Looking ahead further than 'the release we are currently working towards' is unreliable, especially since all development on GIMP is done by unpaid volunteers. _______________________________________________ Gimp-user mailing list Gimp-user@... https://lists.XCF.Berkeley.EDU/mailman/listinfo/gimp-user |
