Hi folks,

I am trying to use LibRAW to convert the CR3 files to tiff and then convert the tiff to jpeg using imagemagick. I want to run this as a container on AWS using Fargate (nodejs application).

The process runs perfectly for CR2 files but for CR3 file the tiff file is not getting created and draw_emu is not throwing any error too.

Command used for conversion:

dcraw_emu -6 -T -w -v test.cr3

Hello,
I need to record 10 bit RG Bayer images from a GigE Vision camera. The DNG format seems to be a solution but I am listening to an alternative. Do you have any advice for me?

According to the https://exiftool.org/TagNames/Panasonic.html, the `AFPointPosition` tag id is 0x004d.

But it seems to the PanasonicRaw tags parsing is used in libraw.

Is it possible to access the 0x004d exif data form modern RW2 file without modifying the source code heavily?

Thanks for your great work.

I have just compiled Libraw with enabling LCMS2 on Win10. From the generated executables it works just fine now and it can profile well. However, I am looking for using it as a dll library in my C++ code, so when I linked the compiled Libraw to my visual studio project I don't seem to be able to apply profiles, just like LCMS is not supported in the API.

Could you please point out if I am missing something? shouldn't Libraw API sees LCMS after compilation ?

This is in reference to using dcraw_emu, though I imagine this could be an issue for libraw in general. I was comparing the output of photos developed with ACES to output with ProPhoto in a color managed photo viewer, and I noticed the colors just seemed a bit off, they looked warmer than I would expect. So, I extracted the ICC profile from the photo and took a look at the primaries, shown in the forward matrix below.
