I found some samples of Fuji X-T4 raws that LibRaw seems to have problems handling.

There seems to be a few things going wrong with this one. The version that parse_fuji_compressed_header() finds is version 0 which is not supported as the check is for version != 1. This image does appear to be compressed though (half the file size of a normal X-T4). Not sure if LibRaw will support a version 0 compression algorithm but just something I noticed, also all the other conditions are satisfied as true for the compression check.

Hi there,

I am using mostly libraw to convert IIQ to tiff and I did notice that some EXIF information such as the GPS coordinates and some various metadata related to the camera itself were missing after the conversion. It there any way to avoid this?

Thanks in advance.

Hello,

I'm experimenting with DNG images loading. I'm using LibRaw and I'm trying to achieve the same result as with dcraw processing, but I can't. White balance is different (see. image in the attachement).

dcraw command I'm using (it's dcraw 9.26 built from the source code):

dcraw -h sunset.dng

dcraw_emu command (it's LibRaw 0.20 built from the sources):

dcraw_emu -h -c 0 sunset.dng

Hello,

I downloaded latest beta1 of libraw 0.20, compiled it with gcc 7.3 inside CodeBlocks IDE.
All is working fine.

No I enabled gpr_sdk as follows:
- I set both compiler options USE_GPRSDK and USE_DNGSDK
- I downloaded gpr_sdk from https://github.com/gopro/gpr as given in file README-GoPro.txt
I did no modification to any of these files
- I put the options where to find the *.h files and tried to compile libraw

Hello,

First of all, thanks for your great work.

I have an issue with reading monochromatic DNG image. The result is pretty weird. I can't figure out if there are problems with the source DNG image itself, or with LibRaw. Maybe I'm using it wrong, but usually DNG images are loaded pretty well. But not this one.

In the attachement there is comparison image just to take a quick look at the problem.
