Parameters
format:
image format:
B = Bitmap
J = JPEG
T = TIFF
width:
number from 0 to 65535
height:
number from 0 to 65535
image:
file name based on a specified format
Function
The GRRD command allows the image data of a specified format to be drawn in a
specified size at a specified location. This command is terminated with the ENDG
command.
The color space for each format is compatible only with RGB. In the case of TIFF
format, the command is compatible with non-compression, LZW, and PackBit. Upon
receipt of incompatible format and/or color-space data, this command is ignored.
Width and height specifications are dependent on the current unit of measurement
(UNIT). If the output image has a specified width of 0, the image will be printed in a
width varying with the height of the output image, while retaining the vertical-horizontal
ratio of the original image data as it is. If the output image has a specified height of 0, the
image will be printed in a height varying with the width of the output image, while
retaining the vertical-horizontal ratio of the original image data as it is. When the output
image has both a specified width and height of 0, the output image pixels will be printed
according to the raster resolution specified by the STR command.
Since the command ends with ;ENDG; do not insert space between the preceding ‘;’ and
ENDG. If space is inserted, the command is ignored.
When monochrome mode is specified, the output is printed as a grayscale image.
File
The following example uses DOS to transfer both the command sequences and the
graphics data to the printing system’s parallel interface.
