HP PCL Soft Font Design 8-15
Delta X (SI)
Specifies the number of quarter-dot units by which the horizontal position within the logi-
cal page coordinate system will be incremented after printing the character. This value is
only used by the printer when the font is proportionally spaced.
The valid range for delta X is 0 to 16800.
Character Data
Character data is a string of bytes containing the dot-per-bit image of the character. If a bit
is set to one, the corresponding dot will be printed. The data is grouped in dot rows; a row
describes a one-dot high strip of the character from left to right, parallel to the printer's ras-
ter scan direction (see Figure 8-5 and Figure 8-6). Zeroed bits must be added to the end of
each row to make it contain an integral number of bytes. The dot rows are organized from
top to bottom of the character, i.e., the first dot row of data corresponds to the top dot row
of the character.
