MacPaint files come in two flavors.
The most common one is straight ported MacPaint files, that is, files having a
"MacBinary" header. The other is "headerless" files, having
no MacBinary header. GFX-View is able to read both types.
MacPaint files may be
cropped or padded out as necessary to fit in the MacPaint format's 576 by 720
format.
