dotCooCoo f32699bea7 File formats: PCX (.pcx) files open and place ...

A new reader, written from the ZSoft PCX Technical Reference Manual, decodes
the run-length encoded scan lines of 1-bit images in the header palette's
first two colors (black and white when the version has no palette or the two
colors are the same), 1-bit images in two to four planes and 4-bit images
with the header's palette (the EGA colors for versions 0 and 3), 2-bit CGA
images in the colors that the header's CGA background and palette settings
pick, 8-bit images with the 256-color palette after the image data (gray
levels without one) and 24-bit images in three planes. The image is stored as PNG at the resolution of the header's HDpi and
VDpi fields.

Open and Place list PCX, and pasting a copied .pcx file and Glass's Load
Texture… read it by its header. A file of another depth or plane count, one
cut short and one whose pixels as RGBA pass the pixel allowance are refused
with a message before its pixels are decoded. The desktop packaging does not
associate .pcx files, and no export writes them.
