Image Area

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.

 

 

Device Control Toolbar

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.

 

 

Start Read Cycle

Starts the camera's read cycle.

 

 

 

Stop Read Cycle

Stops the camera's read cycle.

 

 
Send a Serial Trigger to the Reader

Sends a Serial Trigger to the camera.

 

 

 

Set Window of Interest

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.

 

 

Auto Photometry On

When the reader is in Continuous mode or Presentation mode and you click the Photometry button, the reader maintains optimal self-adjusting photometry (Auto Photometry) 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. The photometry button is highlighted blue with an A in the middle to indicate Auto Photometry is on.

 

When the reader is in Triggered mode and you click the Photometry button, the reader chooses a onetime setting of Exposure and Gain. This is called Quick Photometry.

 

Note: This feature does not function if you are using external strobe lighting. This feature must be turned off if you want to use an external strobe.

 

 

 

Auto Photometry Off

Turns Auto Photometry off.

 

 

 

Focus Button

The focus button, when clicked, activates a dropdown menu to select Autofocus mode or perform a spot focus.

 

 

 

Autofocus On

When the Autofocus button is blue with an A, it means that the reader is using Autofocus.

 

 

 

The  button turns Autofocus on or off. This button is only available when in Continuous or Presentation mode. The camera’s focus setting defined in the Acquire section of the Setup interface are applied to the image when Autofocus is on. The focus setting becomes read-only when Autofocus is on.


 

 

Spot Focus

You can perform a spot focus by clicking the cross hair button  and then clicking a spot in the image to focus.

 

 

Train

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 and Optimize buttons only appear in the Device Control Toolbar when the Read Cycle is configured to look for only 1 symbol.

 

 

 

 

Optimize

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.

 

 

Note: The Train and Optimize button only appears in the Device Control Toolbar when the Read Cycle is configured to look for only 1 symbol.

 

Image Control Toolbar

Fit Image to Window

Fits the captured image to the Image Area window.

 

 
Zoom In

Zooms in on the desired area of the captured image.

 

 
Zoom Out

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.

 

 

Show All Images Used in Read Cycle

Shows all the images that have been captured during the most recent read cycle.

 

 

 

Save Current Image

Allows you to save the current captured image to the location of your choice on your PC.
