The Image Area is the main focus of WebLink. This area allows you to see what currently falls within the reader's field of view, and offers several image control tools.
The Device Control buttons are a convenient way to enable and disable multiple triggering methods and image processing settings in the camera directly from the Image Area.
Starts the camera's read cycle.
Stops the camera's read cycle.
Sends a Serial Trigger to the camera.
Allows you to define the Window of Interest directly in the Image Area interface.
Note: When using an SXGA reader with Auto Photometry enabled, the Window of Interest cannot be set to a width less than 640.
Turns Auto Photometry on. The camera's Auto Photometry settings defined in the Acquire section of the Setup interface are applied to the image when Auto Photometry is on.
When the reader is in Triggered mode and Auto Photometry is on, the best Exposure and Gain settings are determined for the next captured image. Auto Photometry functions differently in Triggered mode than in Continuous mode or Presentation mode: when Auto Photometry is on in Triggered mode, it is only a one-time setting. Exposure and Gain are not adjusted dynamically with each trigger as they would be in Continuous mode or Presentation mode.
When the reader is in Continuous mode or Presentation mode and you click the Auto Photometry button, the reader maintains optimal self-adjusting photometry and focus parameters until you click the button again to turn Auto Photometry off. Symbol data is decoded and symbol information is transmitted repeatedly as long as the symbol is within the reader's field of view and read range.
Turns Auto Photometry off.
Turns Autofocus on. The camera's Autofocus settings defined in the Acquire section of the Setup interface are applied to the image when Autofocus is on.
Turns Autofocus off.
Performs a full symbol calibration to find the best Focus, Exposure, and Gain, and saves relevant information regarding the decoded target symbol to allow greater decodability of similar symbols.
You will see the Determine parameter ranges... and Training Complete messages shown in the examples below during the Train operation.
Note: The Train operation will un-optimize the system once an image is processed, but you can optimize the system again after a Train operation.
Note: The Train button only appears in the Device Control Toolbar when the Read Cycle is configured to look for only 1 symbol.
Saves relevant information about the target symbol, allowing the subsequent symbols to be processed more quickly and consistently.
The reader has three optimization states: un-optimized, optimizing, and optimized.
When the reader is in the un-optimized state and the Optimize button is clicked, the reader enters the optimizing state until a symbol is decoded or until the Optimize button is clicked again to deactivate the optimizing state. When a symbol is decoded during the optimizing state, the reader enters the optimized state.
Note: Because the Train operation (see above) can impact symbol readability, it will un-optimize the system once an image is processed. You can optimize the system again after a Train operation.
Fits the captured image to the Image Area window.
Zooms in on the desired area of the captured image.
Zooms out and decreases the size of the captured image.
Note: You can also zoom in and out by scrolling up or down with your mouse, and you can move the image around by clicking and dragging.
Shows all the images that have been captured during the most recent read cycle.
Allows you to save the current captured image to the location of your choice on your PC.
