| * gui: Add qoi image formatJules Maselbas2022-01-204-0/+776
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The "Quite OK Image Format", aka QOI, aims to be a fast, lossless image compression format, with comparable compression factor against png, and beeing faster to encode and decode. In barebox only care about decoding, the qoi image format might be an intresting alternative to both bmp and png, some kind of midle ground. The project home page can be found at https://qoiformat.org, there is a reference implementation, for both encoder and decoder, in a single header file (qoi.h) hosted at https://github.com/phoboslab/qoi. There is no plan for future version, this is a frozen format. In case the reference implementation should be updated, the qoi.h file must be copied to the lib/gui/qoi.h without requiring modifications.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | If the input is out of the range of the allowed values, either larger than the largest value or closer to zero than the smallest non-zero allowed value, then a division by zero would occur. In the case of input too large, the division by zero will occur on the first iteration. The best result (largest allowed value) will be found by always choosing the semi-convergent and excluding the denominator based limit when finding it. In the case of the input too small, the division by zero will occur on the second iteration. The numerator based semi-convergent should not be calculated to avoid the division by zero. But the semi-convergent vs previous convergent test is still needed, which effectively chooses between 0 (the previous convergent) vs the smallest allowed fraction (best semi-convergent) as the result.
