I was watching this video about the PNG format and toward the end, they mentioned a new computer graphics image format that is fast and has lossless compression: QOI Format (Quite OK Image Format).
From: en.wikipedia.org/wiki/QOI_(image_format)
The Quite OK Image Format (QOI) is:
-a specification for lossless image compression of:
24-bit (8 bits per color RGB) or
32-bit (8 bits per color with 8-bit alpha channel RGBA) color raster (bitmapped) images,
-invented by Dominic Szablewski and
-first announced November 24th 2021
-a specification for lossless image compression of:
24-bit (8 bits per color RGB) or
32-bit (8 bits per color with 8-bit alpha channel RGBA) color raster (bitmapped) images,
-invented by Dominic Szablewski and
-first announced November 24th 2021
Could QOI become the newest default graphic file format?
Another discussion/demo video about QOI:
The QOI spec:
A quick comparison:
Grand total for images (AVG)
decode ms encode ms decode mpps encode mpps size kb rate %
libpng: 7.0 83.8 66.56 5.54 398 24.2
stbi: 7.0 60.5 66.63 7.67 561 34.2
qoi: 2.1 2.9 226.03 161.99 463 28.2
We should definitely be able to implement a QOI library in GFA!
