Is darktable-chart broken again or just me...08/09/23 Nightly not working -- Solved

[todd-prior]

Describe the bug

I believe I am not doing anything wrong exporting to the PFM files with Lab output profile and Lab is set to enabled but when I try to open it in darktable-chart the initial red x on the screen is replaced by a black screen. There is no crashing as was the case previously starting in that window after 3.6 or so. I don't think I am doing anything wrong...can someone confirm... Running latest nightly build for windows...I am going to do my own build and see if maybe that fixes it??

Steps to reproduce

Go to source image tab
Load source image.
Get a black screen in the preview ie no image...

Seems like the export dialogue has to have resize set to no.... mine was set to yes... Things are working now... Sorry for the noise

There seems to be something wrong with the export function for PFMs: I have the same issue, that they show just as black in darktable-chart, and in macOS Finder they are designated as sRGB instead of Lab. Exiftool throws a "file format error".

I got it working shortly, when I exported with various rendering intent options - with relative, saturation and absolute all of a sudden the images displayed correctly in darktable-chart. But I can't reproduce this anymore, no matter which options I select ...
[Edit] the exiftool "file format error" also shows up for the files that display correctly in darktable-chart.

BTW, the file format option now displays just as "PFM" in the dialog, not as "PFM (float)" as described in the darktable-chart section of the manual.

macOS 11.7.8, darktable 4.4.2

I ran into this issue today.

I'm running 4.4.2 and PFMs exported from this version are not appearing in chart-4.4.2. Lab values are NaN.

"allow upscaling" was always set to no. I have tried changing intent with none showing up in chart.

Previously exported PFMs from 4.2.1 are working and show up in chart from 4.4.2.

This issue still happens on chart-4.6.1, but the PFM files created from 4.2.1 are fine
