Step 1 - Take a Picture Using IMGSNP Image Snap - IMGSNP An image is taken whenever the hardware button is pressed, or when the Image Snap (IMGSNP) command is processed. The image snap command has many different modifiers that can be used to change the look of the image in memory. Modifiers always begin with numbers and end with a letter (case insensitive). Any number of modifiers may be appended to the IMGSNP command. For example, you can use the following command to snap an image, increase the gain, and have the beeper sound once the snap is complete: IMGSNP2G1B IMGSNP Modifiers P - Imaging Style This sets the Image Snap style. 0P Decoding Style. This processing allows a few frames to be taken until the exposure parameters are met. The last frame is then available for further use. 1P Photo Style (default). This mimics a simple digital camera, and results in a visually optimized image. 2P Manual Style. This is an advanced style that should only be used by an experienced user. It allows you the most freedom to set up the scanner, and has no auto-exposure. B - Beeper Causes a beep to sound after an image is snapped. 0B No beep (default) 1B Sounds a beep when the image is captured. T - Wait for Trigger Waits for a hardware button push before taking the image. This is only available when using Photo Style (1P). 0T Takes image immediately (default) 1T Waits for a button push, then takes the image L - LED State Determines if the LEDs should be on or off, and when. Ambient illumination (0L) is preferred for taking pictures of color documents, such as ID cards, especially when the scanner is in a stand. LED illumination (1L) is preferred when the scanner is handheld. LED State is not available when using Decoding Style (0P). 0L LEDs off (default) 1L LEDs on 8 - 2
