% - 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 = 97) n% Range: 1 - 99 Example of Target Set Point Percentage at 97%: Example of Target Set Point Percentage at 50%: Example of Target Set Point Percentage at 40%: 1 - 4 Document Reader Imaging Guide
Image Ship - IMGSHP Step 2 - Ship a Picture Using IMGSHP or IMGACP 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 Image taken without Autocrop: Image taken with Autocrop: Document Reader Imaging Guide 1 - 5
