To print a previously created bitmap image:
(cc) IPLOT,E, id (cc)G
(cc) Represents the Special Function Control Code
(SFCC). Enter the specific SFCC for your VGL
configuration.
IPLOT,E, The bitmap image execute (print) command. Enter
IPLOT,E, (both commas are required).
id The bitmap identification number. Enter a one digit
number between 0 and 9. The number must
correspond to the identification number used for a
previously created bitmap, or an error is reported.
(cc)G IPLOT command terminator. Enter the SFCC for
your VGL configuration followed by G to end the
IPLOT command sequence.
Bitmap images are stored in memory only as long as the printer
power is applied, or until being replaced by another bitmap with
the same identification number. The maximum size and number
of bitmaps that may be created is dependent on the amount of
available printer memory. Therefore, it may not be possible to
store up to the maximum number of 10 bitmap images if each is
relatively large.
Bitmap images may be created using the IPLOT, command as a
standard graphics command once graphics mode has been
enabled. However, the IPLOT,E, command must be used as an
extended graphics command within a graphics (^M, ^V, ^E, ^U,
^T, ^J) command sequence to position and rotate the bitmap as
desired.
The bit pattern 11000011 is represented by the hex characters
C3. To specify 10 consecutive C3 patterns, you can enter either
C3C3C3C3C3C3C3C3C3C3 or, using the byte repeat format,
(cc)BC3,10. Also, for clarity, commas may be embedded within
the data stream, such as C3,C3,C3,C3,C3,C3,C3,C3,C3,C3 or
C3C3,C3C3,C3C3,C3C3,C3C3.
A stream of 6 consecutive 00 bytes may be written
00,00,00,00,00,00 or, using the "white" byte repetition format,
(cc)W6.
A stream of 9 consecutive FF bytes may be written
FFFFFFFFFFFFFFFFFF or, using the "dark" byte repetition
format, (cc)D9.
The following illustrates how to create and print a simple bitmap
image. The bitmap is created using 4 bit data, is identified as
bitmap number 0, and is 120 bytes wide. On a 300 dpi printer,
this creates an image that is 3 inches wide (120 bytes*8 bits per
byte = 900 bits, or 900 dots, or 3 inches wide).
