In order to have better character display within windows,

we suggest you to place your designed character font in the

centre of the 10x18 or 12x18 matrix, and let its spaces be

equally located in the four sides of the matrix.

In order to avoid submersion of displayed symbols or

characters into a background of comparable colors, a fea-

ture of bordering which encircles all four sides, or shadowing

which encircles only the right and bottom sides of an individ-

ual display character is provided. Figure 10 shows how a

character is being jacketed differently. To make sure that a

character is bordered or shadowed correctly, at least one dot

blank should be reserved on each side of the character font

Multi-Color Font

The color font comprises three different R, G and B fonts.

When the code of color font is accessed, the separate R/G/B

dot pattern conbime to a multi-color font. When editing color

fonts, there are 9 items for selection. They are eight colors

and transparent option for selections in font editor. Please

refer to following diagram.
