Convert PCX to UIL

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 UIL file extension stands for User Interface Language and is associated with the X-Motif UIL Table. It is a plain text file format used by the UIL compiler to create user interfaces for the X Window System. UIL files define menus, buttons, dialog boxes, and other graphical user interface components. Introduced by The Open Group, this format allows developers to describe the initial state of a user interface, including widgets, resources, and callbacks. The UIL file is compiled into a UID file, which can be accessed by Motif Resource Management functions within an application.
