Images in the HRZ format
always have 24 bits of color and the fixed dimensions 256 by 240 pixels. Images
with differing dimensions will be padded or cropped to fit in this space when
they're translated to HRZ. Images with fewer colors will be promoted to 24 bits.
This is a fairly specialized format – if you aren't using slow scan
television, you probably don't need it. You might well ask what slow scan
television is – not quite sure. Conventional television seems slow enough.
GFX-View
only reads uncompressed HRZ files.
