- 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.
- An ICO file is an image format used to store icons for Windows programs, files, and folders. It contains two bitmaps: 1) the AND bitmap - the image mask (which determines what part of the icon is transparent) and 2) the XOR bitmap - contains the icon which is mapped onto the image mask. ICO files can be modified to create custom icons.
