Native format of the Krita painting program, developed by the Krita Foundation.
Description
The RL4 file type is associated with the Windows operating system, particularly designed for bitmap images. It specifically refers to a bitmap file format used in Windows environments for storing graphical images in a 4-bit RLE (Run-Length Encoded) format. This compression technique helps in reducing the file size without sacrificing the image quality significantly. RL4 files are typically used for storing simple graphics or icons with a limited color palette, making them efficient for applications where space conservation is important.
Image file saved by the Krita painting program. A Krita file is a zip archive holding the full layer stack: each layer's pixel data as compressed tiles, its name, position, opacity, blending mode and visibility, plus a merged preview of the whole image.
