RAW image file format

[luca]

Hello everybody.

I'm quite new to the Raspberry and OPenGLES (i had some littel OGL experience some years ago).

I'm trying to modify the /opt/vc examples and moving on from there, i cant' find how the RAW images used as textures (hello_traingle) should be generated. I've read somewhere (can't find it again) it's an uncompressed TGA, but saving as TGA and renaming doesn't work.

Any info or pointers welcome.

Thank you.

These RAW images are simply the RGB values of the image saved as a file. There is no header just the RGB values of the images. The images are saved as rows, top row first. pixels from left to right. Each file is 49152 bytes long (128 x 128 x 3). I am sure there are lots of programs around that will create a raw image file. Hope that helps!

Thanks!
Looking after this info i found somebody who said to save as "C code" from gimp and then including, which seems over complicated, but looking for it i found a "RAW image data" option without an associated file extension in the GIMP select file type dropdown in the save as window
so now just rename the file to raw and load and it works.

Thanks.
