Disk #9: High Resolution Graphics

The HiRes collection contains macros and subroutines for plotting and displaying high resolution graphics. This includes macros to:

Flip between HiRes pages, both as working pages and viewing pages
Plot a single HiRes pixel
Fill the HiRes page with a given color
Plot horizontal, vertical and diagonal lines
Plot text characters to the HiRes screen, individually or as a string
Plot entire bytes to the HiRes screen, easily allowing for the plotting of tiles
