What is PCX Viewer and what does it do?
The PCX Image Viewer decodes legacy ZSoft PCX bitmap files and renders them to an HTML5 Canvas.
Supports 1, 4, 8, and 24-bit PCX formats with RLE decompression.

How does PCX Viewer work?
Reads the 128-byte PCX header to extract dimensions and bit depth, decodes RLE scanlines byte-by-byte, maps indexed pixels through the 256-color palette, and writes RGBA data to ImageData for canvas rendering.
