8 - 5
% - Target Set Point Percentage
Sets the target point for the light and dark values in the captured image. A
setting of 75% means 75% of the pixels are at or below the target white value,
and 25% of the pixels are above the target white value. Altering this setting
from the default is not recommended under normal circumstances. To alter
grayscale values, W - Target White Value should be used.
(Default = 50)
n% Range: 1 - 99
Step 2 - Ship a Picture Using IMGSHP
Image Ship - IMGSHP
An image is taken whenever the button is pressed, or when the Image Snap
(IMGSNP) command is processed. The last image is always stored in memory.
You can “ship” the image by using the IMGSHP command.
The image ship commands have many different modifiers that can be used to
change the look of the image output. Modifiers affect the image that is transmit-
ted, but do not affect the image in memory. Modifiers always begin with a num-
ber and end with a letter (case insensitive). Any number of modifiers may be
appended to the IMGSHP command. For example, you can use the following
command to snap and ship a bitmap image with gamma correction and docu-
ment image filtering:
IMGSNP;IMGSHP8F75K26U
