**Brandy Breeze**: 🍾 General-purpose compression algorithm.
Built on top of [RLE](https://en.wikipedia.org/wiki/Run-length_encoding), [BWT](https://en.wikipedia.org/wiki/Burrows%E2%80%93Wheeler_tra…

[RLE](https://en.wikipedia.org/wiki/Run-length_encoding) is a common algo. and probably nothing special, but in case of data streams with TEXT-type data, we can use RLE to optimize bytes used to trans…

Mostly as an exercise, implement a compression algorithm.
Akin to RLE (Run-Length Encoding) and double RLE:
Find the longest repeating substring. Replace it with a special symbol. Store the mappin…

I see RLE in imcs,it is greate,but I think the benefit is limited for real world compare with common compression algorithm such as lz4,lzo,snappy.
infobright can reach 10:1~40:1 compression ratio,may …

fpnge is pretty fast, so I was wondering what, in theory, could be done to improve compression slightly without sacrificing too much speed. I was hoping you might have some ideas on the topic (regardl…

Based on the PSD Export example from #239 standard functionality should be added for writing PSD files.
The PSD files should be layered when created from `TCustomImage32` (with layers) and non-layere…
