I have a uint16 image data from a thermal camera and I would like to save a paletted jxl file where I specify the palette. The palette would map the 16 bit values to 2^16 RGB colors of my choosing. This would be ideal as it would allow me to glance at ... | [question/feature] Is there a way to specify my own palette? | https://api.github.com/repos/libjxl/libjxl/issues/2826/comments | 7 | 2023-09-26T16:26:13Z | 2023-12-13T22:02:06Z | https://github.com/libjxl/libjxl/issues/2826 | 1,913,884,220 | 2,826 |

Libjpeg library allows reading source pixels (RGB/Gray in YCbCr color space in most cases) from a jpeg file.
I noticed that the libjxl examples (decode-oneshot) always convert pixels to a specific format. Is there a way to access the original pixels without converting them to a different format? | [question/feature request] Is there a way to read source pixels? | https://api.github.com/repos/libjxl/libjxl/issues/2824/comments | 3 | 2023-09-26T08:27:00Z | 2023-09-27T13:41:20Z | https://github.com/libjxl/libjxl/issues/2824 | 1,912,976,792 | 2,824 |

Does the decoder now depend on lcms or is it solely a result of refactoring? Can it be split as it was if it does not? | Building decoder only now requires lcms | https://api.github.com/repos/libjxl/libjxl/issues/2822/comments | 3 | 2023-09-25T12:25:26Z | 2023-10-16T21:29:11Z | https://github.com/libjxl/libjxl/issues/2822 | 1,911,398,587 | 2,822 |
