RAW data enquiry

Hello,

My name is Tyler Prior. Im a digital artist focusing on the dualities of data and the links that can be drawn from them on both personal and socio-political topics.

Im trying to write a programme where I can show the live changes of RAW data when it is simultaneously experienced as both .wav and .raw (a methodically similar example would be data-bending). However, I cant find a way to interpret RAW data as an image the same way in which both GIMP and Photoshop does (open -> raw image data -> set pixel dimensions - see example).

I'm interested in this function in particular: `raw_load_gray()` that parses RAW 8 bit data https://github.com/GNOME/gimp/blob/e09e563a70fef5d7dd55e5e8d0e280348f1ef9d4/plug-ins/common/file-raw-data.c#L855 do you have comment or eresources for the thinking behind the function?

I look forward to hearing from you.

Best,

Tyler Where this email is unrelated to the business of University of the Arts London the opinions expressed in it are the opinions of the sender and do not necessarily constitute those of University of the Arts London.

Not replying to your question; since I do not know these parts of the GIMP code, but you might have fun experimenting with an expriment by Amir Hassan, soundfumble. where you can start out with images/photos used as "glitch" audio, that gets filtered and manipulated live in GIMP. You might have to use an older version of GIMP to make it work.
