^GF
Graphic Field
Description The ^GF command allows you to download graphic field data directly into the
printer’s bitmap storage area. This command follows the conventions for any other field,
meaning a field orientation is included. The graphic field data can be placed at any location
within the bitmap space.
Format ^GFa,b,c,d,data
This table identifies the parameters for this format:
Parameters Details
a = compression type Accepted Values:
A
= ASCII hexadecimal (follows the format for other
download commands)
B
= binary (data sent after the c parameter is strictly binary)
C
= compressed binary (data sent after the c parameter is in
compressed binary format. The data is compressed on
the host side using Zebra’s compression algorithm. The
data is then decompressed and placed directly into the
bitmap.)
Default Value: A
b = binary byte count Accepted Values: 1 to 99999
This is the total number of bytes to be transmitted for the total
image or the total number of bytes that follow parameter
d.
For ASCII download, the parameter should match parameter
c. Out-of-range values are set to the nearest limit.
Default Value: command is ignored if a value is not specified
c = graphic field
count
Accepted Values: 1 to 99999
This is the total number of bytes comprising the graphic
format (width x height), which is sent as parameter
d. Count
divided by bytes per row gives the number of lines in the
image. This number represents the size of the image, not
necessarily the size of the data stream (see
d).
Default Value: command is ignored if a value is not specified
