[Name] Print raster graphics [Operation]
[Format] 1BH, 2EH, c, v, h m, nL, nH, d1...dk
[Range of Definition] c=0, 1, 2 (a description of the behavior of this function when c == 2 is in the next section)
v=5, 10, 20, 30 (v/3600 dpi)
h=5, 10 (h/3600 dpi)
0  nL  255
0  nH  127
0  d  255
m=1, 8, 24, (color mode)
[Function] This function prints raster graphics at
c style compression, with
y /3600 dpi vertical density, and
h /3600 dpi horizontal density, to print out
m raster lines, or scan lines, or rows of dots in the vertical direction, covering
(nH * 256) + nL total dots, using
k subsequent bytes of data.
1) If c has any value other than those specified above, this command terminates at the instant
that c is processed.
If either v or h has any value other than the above, this command is ignored.
2) The actual image pattern is generated according to a raster method determined by the
following parameters:
c: printing mode
00H: full graphics mode (non-compressed mode)
01H: run-length encoded compression mode
02H: TIFF compression mode
If TIFF compression mode is used, then m must be
equal to 1.
Explanation of this function where c == 2 is in the
next section
v: printing density in the vertical direction v/3600 (dpi)
h: printing density in the horizontal direction h/3600 (dpi)
m: number of dots (rows) in the vertical direction, number of raster or
scan lines
nL, nH: number of dots covered in the horizontal direction =
((256 x nH) + nL)
k: number of items of data = m x int((nH x 256 + nL + 7)/8) for
uncompressed data
= undeterminable amount for compressed data
d: data
Full graphics mode (non-compressed mode)
In full graphics mode, all of the data is transferred in raster format.
Raster data that extends beyond the ((256 * nH) + nL) dot area boundary will be
automatically clipped or discarded.
The total amount of data sent is k = int((256 x nH + nL + 7)/8) x m bytes.
256*nH+nL dots
int((256*nH+nL+7)/8) bytes
