Command: Graph/Modes/Low 320x200 4-color < GML >
Purpose: Select low-res CGA graphics mode for displays
Information:
In this mode, your system can display 320 dots horizontally
and 200 dots vertically. This means up to 320 warp by 200
weft with Variable Size Off and Zoom level 0.
With Zoom 1 and above, a Horizontal Zoom Aspect factor of 10
with a Vertical Zoom Aspect factor of 9 will provide nearly
square blocks. 6:5 is slightly less effective.
Only three colors plus the background are visible. You can
change the palette of three colors and the background with
this menu or while the weaving is displayed. During a CGA
low-res display, the left and right arrow keys change the
background color and the up and down keys change the
palette of three "foreground" colors.
Comments:
The 16 colors displayable in text mode are combined into 4
in CGA low-res graphics. This limits the display of multi-
color-generated patterns.
The background color can be any of the 16 CGA colors.

Command: Graph/Modes/High 640x200 2-color < GMH >
Purpose: Select Hi-res CGA graphics modes for displays
Information:
In this mode, your system can display 640 dots horizontally
and 200 dots vertically. This means up to 640 warp by 200
weft with Zoom level 0.
With Zoom 1 and above, a Horizontal Zoom Aspect factor of 20
with a Vertical Zoom Aspect factor of 9 will provide nearly
square blocks. 12:5 is less effective, but still close.
Only one foreground and background color are available. You
can change the foreground color from this menu and the
background color with Color/BackgroundGraph. During a
CGA hi-res weaving display, the up and down arrow keys
change the foreground to any of 16 colors.

Command: Graph/Modes/Palette for CGA Lo-Res < GMP >
Purpose: Select one of four CGA low-res graphics palettes
Information:
The three "foreground" colors are determined by the
interaction of your weaving's color numbers and the current
display palette selected, as shown by the table below. You
can switch palettes while the weaving is displayed by using
the UpArrow and DownArrow keys; you have to edit the color
numbers in the weaving for other changes.
The background color is displayed by color numbers 4,8,12, &
16. The actual background color is determined by the
left/right arrow keys while the weaving is onscreen or the
Color/BackgroundGraph option first (16 choices).
