Creating an image from arrays of floats in C/C++

Hello all,
I’m in the process of creating a little system that runs compute shaders but I need a way to save and load information in the form of images.

I’ve only managed to create flat colour images using BKE_image_add_generated from image.cc but would like to create images from float arrays for the rgba channels and read data in that way from existing images.

I’ve had a look at the ImBuf struct but i’m not sure how to get them to take my data.
Thank you!

If you have an array of floats that are arranged RGBA you could just do something like:

ImBuf *image = IMB_allocFromBuffer(NULL, myarray, width, height, 4);

Thank you! That’s a good bit simpeler then my approach :smiley:
