Vince Weaver 70ab2f4223 hgr-util: png2hgr: try to autodetect correct black and white better this is a bit tricky, because we support forcing black/white colors by using slightly different palette entries, so we don't want to completely ignore the difference in case the image is trying to force one or another of the black/white colors for alignment or xdraw reasons		2021-06-29 00:58:09 -04:00

These are some tools for manipulating HGR Apple 2 graphics.


pcx2hgr:	converts a 140x160 (or 140x192) PCX image file
                into an Apple II HGR graphics file that can 
		be loaded with "BLOAD IMAGE,A$2000"

		To get it to work, create an image with the GIMP.
		Scale to 140x160.  Save as indexed with the 
		included "hgr.pal" palette.

                It also works with 280x160 but in that case it ignores
		colors and only generates black and white output.


pcx2dhgr:	converts to Double Hires
	

shape_table:  create an Apple shape table for use with
              DRAW and XDRAW commands
	      
	      can generate BASIC code to load it (via DATA) or
	      else a binary version that can be BLOADed
