Hatch_10i, Hatch_10o, Hatch_12i, Hatch_12o,

Hatch_24i, Hatch_24o, Hatch_24s, Hatch_G,

Hatch_M, GRN_HTCH, and MAGENTA

Description

The primary versions consist of a white, green (G

 

and GRN), or magenta (M) crosshatch drawn on a

 

black background. The lines form square boxes.

 

A single pixel dot is located in the center of each

 

crosshatch box. The number of boxes formed

 

depends on the version of the image selected and

 

the screen aspect ratio of the currently loaded

 

format. The number in the image’s name refers to

 

the number of boxes that are formed along the

 

minor axis for most aspect ratios. The firmware

 

calculates the ratio and then finds the closest match

 

from the table on the next page. Versions ending

 

in i draw from the inside (center) out. Any partial

 

boxes are placed around the perimeter of the image.

 

Versions ending in o draw from the outside in.

 

Any partial boxes are placed along the centerlines

 

of the image. Versions ending in s are the “i” version

 

plus a 1 pixel thick border.

 

The secondary versions invert the images to black

 

lines and dots on a white background. Hatch_G,

 

Hatch_M, GRN_HTCH and Magenta do not have

 

secondary versions.
