Convert J2C to PCX

The J2C file extension stands for JPEG 2000 Code Stream, a format defined in Part 1 of the JPEG 2000 standard. Developed by the Joint Photographic Experts Group (JPEG) from 1997 to 2000, J2C files utilize wavelet-based compression, supporting both lossy and lossless compression. This format is primarily used for high-quality image storage and transmission, offering superior compression efficiency and flexibility compared to the original JPEG standard. J2C files are often embedded within other file formats like JP2 for enhanced metadata support.

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.
