Convert PCX to ICB

The PCX file extension, standing for PiCture eXchange, is a raster image format developed by ZSoft Corporation in 1985 for its PC Paintbrush software. It became one of the first widely accepted DOS imaging standards, supporting palette-indexed images from 2 to 256 colors and later true-color (24-bit) images. PCX files use RLE (Run-Length Encoding) compression, making them smaller in size. Although largely replaced by formats like BMP, JPEG, and PNG, PCX was pivotal in early computer graphics and is still supported by various image processing software.

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.
