-- About
|
||||
|
||||
QOI encodes and decodes images in a lossless format. An encoded QOI image is
|
||||
usually around 10--30% larger than a decently optimized PNG image.
|
||||
|
||||
QOI outperforms simpler PNG encoders in compression ratio and performance. QOI
|
||||
images are typically 20% smaller than PNGs written with stbi_image but 10%
|
||||
larger than with libpng. Encoding is 25-50x faster and decoding is 3-4x faster
|
||||
than stbi_image or libpng.
|
||||
|
||||
|
||||
-- Synopsis
|
||||
|
||||
// Define `QOI_IMPLEMENTATION` in *one* C/C++ file before including this
|
||||
// library to create the implementation.
|
||||
|
||||
#define QOI_IMPLEMENTATION
|
||||
#include "qoi.h"
|
||||
|
||||
// Load and decode a QOI image from the file system into a 32bbp RGBA buffer
|
||||
int width, height;
|
||||
void *rgba_pixels = qoi_read("image.qoi", &width, &height, 4);
|
||||
|
||||
// Encode and store an RGBA buffer to the file system
|
||||
qoi_write("image_new.qoi", rgba_pixels, width, height, 4);
|
||||
|
||||
|
||||
-- Documentation
|
||||
|
||||
This library provides the following functions;
|
||||
- qoi_read -- read and decode a QOI file
|
||||
- qoi_decode -- decode the raw bytes of a QOI image from memory
|
||||
- qoi_write -- encode and write a QOI file
|
||||
- qoi_encode -- encode an rgba buffer into a QOI image in memory
|
||||
|
||||
See the function declaration below for the signature and more information.
|
||||
|
||||
If you don't want/need the qoi_read and qoi_write functions, you can define
|
||||
QOI_NO_STDIO before including this library.
|
||||
|
||||
This library uses malloc() and free(). To supply your own malloc implementation
|
||||
you can define QOI_MALLOC and QOI_FREE before including this library.
|
||||
|
||||
|
||||
-- Data Format
|
||||
|
||||
A QOI file has a 12 byte header, followed by any number of data "chunks".
|
||||
|
||||
struct qoi_header_t {
|
||||
char [4]; // magic bytes "qoif"
|
||||
unsigned short width; // image width in pixels (BE)
|
||||
unsigned short height; // image height in pixels (BE)
|
||||
unsigned int size; // number of data bytes following this header (BE)
|
||||
};
|
||||
|
||||
The decoder and encoder start with {r: 0, g: 0, b: 0, a: 255} as the previous
|
||||
pixel value. Pixels are either encoded as
|
||||
- a run of the previous pixel
|
||||
- an index into a previously seen pixel
|
||||
- a difference to the previous pixel value in r,g,b,a
|
||||
- full r,g,b,a values
|
||||
|
||||
A running array[64] of previously seen pixel values is maintained by the encoder
|
||||
and decoder. Each pixel that is seen by the encoder and decoder is put into this
|
||||
array at the position (r^g^b^a) % 64. In the encoder, if the pixel value at this
|
||||
index matches the current pixel, this index position is written to the stream.
|
||||
|
||||
Each chunk starts with a 2, 3 or 4 bit tag, followed by a number of data bits.
|
||||
The bit length of chunks is divisible by 8 - i.e. all chunks are byte aligned.
|
||||
|
||||
QOI_INDEX {
|
||||
u8 tag : 2; // b00
|
||||
u8 idx : 6; // 6-bit index into the color index array: 0..63
|
||||
}
|
||||
|
||||
QOI_RUN_8 {
|
||||
u8 tag : 3; // b010
|
||||
u8 run : 5; // 5-bit run-length repeating the previous pixel: 1..32
|
||||
}
|
||||
|
||||
QOI_RUN_16 {
|
||||
u8 tag : 3; // b011

||||

|
||||
}
|
||||
|
||||
QOI_DIFF_16 {
|
||||
u8 tag : 3; // b110
|
||||
u8 dr : 5; // 5-bit red channel difference: -15..16
|
||||
u8 dg : 4; // 4-bit green channel difference: -7.. 8
|
||||
u8 db : 4; // 4-bit blue channel difference: -7.. 8
|
||||
}
|
||||
|
||||
QOI_DIFF_24 {
|
||||
u8 tag : 4; // b1110
|
||||
u8 dr : 5; // 5-bit red channel difference: -15..16
|
||||
u8 dg : 5; // 5-bit green channel difference: -15..16
|
||||
u8 db : 5; // 5-bit blue channel difference: -15..16
|
||||
u8 da : 5; // 5-bit alpha channel difference: -15..16
|
||||
}
|
||||
|
||||
QOI_COLOR {
|
||||
u8 tag : 4; // b1111
|
||||
u8 has_r: 1; // red byte follows
|
||||
u8 has_g: 1; // green byte follows
|
||||
u8 has_b: 1; // blue byte follows
|
||||
u8 has_a: 1; // alpha byte follows
|
||||
u8 r; // red value if has_r == 1: 0..255
|
||||
u8 g; // green value if has_g == 1: 0..255
|
||||
u8 b; // blue value if has_b == 1: 0..255
|
||||
u8 a; // alpha value if has_a == 1: 0..255
|
||||
}
|
||||
|
||||
The byte stream is padded with 4 zero bytes. Size the longest chunk we can
|
||||
encounter is 5 bytes (QOI_COLOR with RGBA set), with this padding we just have
|
||||
to check for an overrun once per decode loop iteration.
