Hi,
I'm using LibRaw to decode Sony ARW files.
One option of my code is to allow user to specify they'd like RGB output instead of RGGB.
When this option is chosen I call dcraw_process (result is LIBRAW_SUCCESS), followed by dcraw_make_mem_image with address of my result-code int.

This works great when memory is available.
However, when memory gets tight, this call appears to fail (returns NULL), but the error code is not populated (per "...If caller has passed not-NULL value as errorcode parameter, than *errorcode will be set to error code...").

Hello,

For Panasonic 14 bits compressed images (like for the S1H camera), I wrote a decoder (in Pascal).
It is very similar to the 12 bits compressed, but differs in some details from the routine found in dcraw.
The cmp=4 is the code dedicated to 14bits compressed. cmp=3 is the code for 12 bits compressed inspired from dcraw.c - it's probably easy to rewrite it in C readinf the dcraw source in parallel.

The code ran correctly on all images I have pumped for this camera from photographyblog.com .

I'm porting my image processing application to Windows 10 with Qt 5.14. The port is complete, everything is functional, except for libraw, where I'm having problems linking the static library.

In your windows native building instructions, you say:

if static linking is necessary, one should link applications with library libraw_static.lib and set the preprocessor option /DLIBRAW_NODLL during compilation.

I am trying to use the C API to output a totally RAW tiff but I don't see a C API "setter" for specifying a tiff format. I can create a ppm file.

Hi,

Thanks very much for libraw and for the latest update!

I'm trying to build libRaw with Gopro raw support against the current Adobe DNG sdk, as explained in README.GoPro.txt, but I can't get it to build. I'm using https://download.adobe.com/pub/adobe/dng/dng_sdk_1_5.zip

I've applied the patches you mentioned. Compilation of gpr_sdk fails with:
