Step 2 - Ship a Picture Using IMGSHP or IMGACP
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 or IMGACP command.
The image ship and image auto crop commands have many different modifiers that can be used to change the look of the image
output by the document reader. Modifiers affect the image that is transmitted, but do not affect the image in memory. Modifiers
always begin with a number and end with a letter (case insensitive). Any number of modifiers may be appended to the IMGSHP
or IMGACP command. For example, you can use the following command to snap and ship a bitmap image with gamma
correction and document image filtering:
IMGSNP;IMGSHP8F75K26U
Image Auto Crop - IMGACP
Image Auto Crop removes unwanted portions of an image, such as blank space surrounding an image. Image Auto Crop uses
artificial intelligence to search for the area of the image that contains text. It then crops the image to just that area and adjusts it
to a horizontal display. Depending on the size and position of the document, this may possibly result in an upside-down or
sideways image. The image can then be rotated to the proper orientation using your local software. Smaller documents will crop
more quickly than larger documents. The accuracy of auto crop is affected by the density of the text, amount of non-text features,
and contrast in the image.
Note: Any modifiers to IMGACP are applied to the resultant, auto cropped image.
The same modifiers are used for image ship and image auto crop. The following command was used to take and crop an image
that had the white value lowered and the edge sharpen filter on:
IMGSNP75W;IMGACP14E
