If I have bayer data, how to process it to get the image?

Submitted by Kuro on

I've a custom decompress code that decompresses a certain compressed RAW image into bayer monochrome 16-bit data. The actual bit depth of the sensor is 14-bit.

Now that I've the bayer data, how do I use LibRaw to turn it into a useable image?

My code currently looks like this:

RAW EXIF tag editing Anamorphic de-squeeze:

Submitted by preppietrash on

could the following be achieved with Libraw?

apply a custom aspect ratio to Fujifilm.RAF RAW images are made with an anamorphic lens and applied to a specific aspect ratio de-squeeze (1.33X or 1.5X) on the horizontal axis. that will also be applied to any embedded preview images.

once the files have the proper aspect display metadata Capture One Pro will be used to process and export the final deliverables.

I am on MACOS Ventura.

I have not used Libraw in the past. but I am capable of following directions and asking for help if I’m stuck.

Identify() function working

Submitted by sahil on

I was trying to understand the code base and for ARW files how does the identify function call in the open_datastream() function extract the meta-data from that file
I am not able to understand the control of how it would work , would be really useful if someone mentions the specific lines in identify.cpp which will be used for the ARW format or which functions are called in the pipeline

Windows exe with metadata and GoPro support

Submitted by gEEvEE on

Hi all,

I am not capable of compiling code so I use the precompiled Windows *.exe files.
Using those, is there a way to get the file metadata?

Also, the "unprocessed_raw.exe" does not read GoPro 10 and 11 GPRs, but RawDigger does (because it uses the SDK). Is it possible to provide an *.exe file that enables me to save the GoPro RAW as tiff?

Cheers!

Olympus OM-1

Submitted by David Partridge on

Is reported by the camera as "Olympus OM-1" but it only appears in the supported camera list as "OM Digital Solutions OM-1"

This means that software attempting to check that a camera is supported by using the camera list won't find it.

I've updated my local copy of LibRaw to add "Olympus OM-1" so that either string will be recognised. It would be great if you could also add "Olympus OM-1" in addition to "OM Digital Solutions OM-1".

David
