  • Page 7: Chapter 1 - Imaging Commands

    Imaging Commands The document reader is like a digital camera in the way it captures, manipulates, and transfers images. The following commands allow you to alter the way the document reader performs these functions. Single-Use Basis Imaging Commands with their modifiers send instructions to the document reader on a single-use basis, and take effect for a single image capture.

  • Page 8: T - Wait For Trigger

    T - Wait for Trigger Waits for a hardware button push before taking the image. This is only available when using Photo Style (1P). Takes image immediately (default) Waits for a button push, then takes the image L - LED State Determines if the LEDs should be on or off, and when.

  • Page 9: G - Gain

    G - Gain Gain is used in Manual Style only (2P). Like a volume control, the gain modifier boosts the signal and multiplies the pixel value. As you increase the gain, the noise in an image is also amplified. No gain (default) Medium gain Heavy gain Maximum gain...

  • Page 10: Target Set Point Percentage

    % - 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.

  • Page 11: Step 2 - Ship A Picture Using Imgshp Or Imgacp

    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.

  • Page 12: Imgshp/Imgacp Modifiers

    IMGSHP/IMGACP Modifiers A - Infinity Filter Enhances pictures taken from very long distances (greater than 10 feet or 3m). The Infinity Filter should not be used with Image Auto Crop - IMGACP (page 1-5). Infinity filter off (default) Infinity filter on Example of Infinity Filter off (0A) from approximately 12 feet (3.66m) away: C - Compensation...

  • Page 13: E - Edge Sharpen

    E - Edge Sharpen An edge sharpen filter cleans up the edges of an image, making it look cleaner and sharper. While edge sharpening does make the image look cleaner, it also removes some fine detail from the original image. The strength of the edge sharpen filter can be entered from 1 to 24.

  • Page 14: I - Invert Image

    I - Invert Image Invert image is used to rotate the image around the X or Y axis. Note: This feature should only be used with IMGACP (page 1-5) may produce undesired results since Image Auto Crop attempts to rotate an image to a horizontal display.

  • Page 15: Iu - Image Adaptive Text Filter

    IR - Image Rotate Note: This feature should only be used with IMGACP (page 1-5) may produce undesired results since Image Auto Crop attempts to rotate an image to a horizontal display. Image as snapped (rightside up) (default) Rotate image 90 degrees to the right Rotate image 180 degrees (upside down) Rotate image 90 degrees to the left Example of Image Rotate set to 0ir:...

  • Page 16: Is - Unsharp/Brighten Filter

    IS - Unsharp/Brighten Filter The Unsharp/Brighten Filter automatically sharpens the text and brightens the contrast of the image, making text more readable. This is similar to the Image Adaptive Text Filter, however it brightens the image as well. You should test both image processing techniques to determine which filter works best for your environment.

  • Page 17: L, R, T, B, M - Image Cropping

    L, R, T, B, M - Image Cropping Note: Image Cropping should not be used with Ships a window of the image by specifying the left, right, top, and bottom pixel coordinates. Device columns are numbered 0 through 1279, and device rows are numbered 0 through 959. The left edge of the shipped image corresponds to column n of the image in memory.

  • Page 18: S - Pixel Ship

    S - Pixel Ship Pixel Ship sizes an image in proportion to its original size. It decimates the image by shipping only certain, regularly spaced pixels. For example, 4S would transmit every fourth pixel from every fourth line. The smaller number of pixels shipped, the smaller the image, however, after a certain point the image becomes unusable.

  • Page 19: Blur Image

    V - Blur Image Smooths transitions by averaging the pixels next to the hard edges of defined lines and shaded areas in an image. Don’t blur (default) Blur Example of Blur Image Off (0V): W - Histogram Ship A histogram gives a quick picture of the tonal range of an image, or key type. A low-key image has detail concentrated in the shadows;...

In this example, the aimer is centered over the signature capture area and the trigger is pressed.

  • Page 21: B - Output Image Height

    B - Output Image Height This option is used to size the image vertically. If using this option, set the resolution (R) to zero. Example of Image Height set to 50B: D - Pixel Depth This indicates the number of bits per pixel in the transmitted image, which defines whether it will be grayscale or black and white.

  • Page 22: R - Resolution Of Signature Capture Area

    R - Resolution of Signature Capture Area The resolution is the number of pixels that the document reader outputs per each minimum bar width. The higher the value for R, the higher the quality of the image, but also the larger the file size. Values begin at 1000. The document reader automatically inserts a decimal point between the first and second digit.

  • Page 23: Chapter 2 - Serial Default Commands

    Serial Default Commands The following serial default commands are used to program the imaging features for your document reader. For complete descriptions of each command, refer to the corresponding page in this manual. For non-imaging programming commands, refer to the Barcode Manual. The following commands can be sent via a PC COM port using terminal emulation software.

  • Page 24: Concatenation Of Multiple Commands

    Concatenation of Multiple Commands Multiple commands can be issued within one Prefix/Storage sequence. Only the Tag, SubTag, and Data fields must be repeated for each command in the sequence. If additional commands are to be applied to the same Tag, then the new command sequence is separated with a comma (,) and only the SubTag and Data fields of the additional command are issued.
