Convert FF to ICB

The Farbfeld (FF) file extension stands for "Farbfeld Lossless Image", a format designed for simplicity and efficiency in parsing and piping image data. Introduced by the Suckless community, Farbfeld stores images in a straightforward, uncompressed format, making it ideal for use with external compression algorithms. This format uses 32-bit RGBA values for each pixel, ensuring lossless quality. Its history traces back to the need for a minimalistic, easily manageable image format that avoids the complexity of integrated compression found in formats like PNG.

The ICB file extension, associated with Targa Graphics, stands for Image Capture Board. It was originally used with the AT&T EPICenter Image Capture Board video card and software like ICB-PAINT and TARGA-PAINT. This format is a raster graphics file used for storing and exchanging deep-pixel images, supporting 8, 16, 24, and 32 bits per pixel. Developed by Truevision Inc., it played a significant role in early computer graphics for high-color display on IBM-compatible PCs.
