Quite OK Image (QOI) format CLI encoder/decoder from and to raw RGB/RGBA images with 8-bit color depths.
To build the project, simply run:
make
The binary will then be generated in the project root folder with the name qoify.
P.S.: If you're using a compiler other than gcc, make sure to modify the Makefile accordingly. The program also makes use of the POSIX-exclusive getopt() function, so it will not work on Windows; at least not until I replace it with a purely libc-based logic.
qoify - Convert between RAW and QOI image formats
Usage:
Encode: qoify -e --width <w> --height <h> [--no-alpha] input output
Decode: qoify -d input output
Options:
-d, --decode Decode QOI file to RAW format
-e, --encode Encode RAW file to QOI format
-w, --width <n> Width of input image (required for encoding)
-h, --height <n> Height of input image (required for encoding)
--no-alpha Input image is RGB (no alpha channel)
--help Display this help message
Examples:
qoify -e -w 800 -h 600 input.raw output.qoi # Encode RGBA RAW to QOI
qoify -e -w 800 -h 600 --no-alpha in.raw out.qoi # Encode RGB RAW to QOI
qoify -d image.qoi image.raw # Decode QOI to RAW
Note: RAW files must be uncompressed RGB/RGBA data
For now, since the decoder logic is not yet implemented, I test by viewing the input RAW and output QOI images in online viewers. Another possible way would be to use the encoder from the official repo and compare the hashes of its and my outputs.
Once the decoder logic is implemented though, it will be possible to simply encode then decode an image, and check that its unchanged.
P.S. All tests currently included in the test directory are successful.
