Evaluation
In Evaluation, you can view images
currently in the reader, capture and
decode a symbol, save it as a digital
file, and perform histogram and line
scan evaluations.
When you click on the Evaluation tab,
you will see the images that are currently
stored in the reader.
Click Receive to refresh the view.
Click Capture/Decode to display the
current image in the scanner. Only one
capture/decode event will occur
regardless of read cycle settings.
Click Read to trigger a read cycle. If
there’s enough time in the read cycle
up to 8 good reads can be captured
and displayed depending on the number
enabled in Number of Captures under
Capture Mode in the Camera Setup
menu tree to the left of the tabs.
If you click Save , the current image will be saved to as a file to the location of your choice.
Note: An image can only be saved in the format that the image was captured in. JPEG
images will be saved as a .jpg, bitmaps as a .bmp.
When you click the JPEG Image box, notice that the Line Scan Button is grayed out.
The JPEG option allows faster captures and transfers, but since the JPEG standard
compresses image data, it is not suitable for the more rigorous demands of a line scan
evaluation.
JPEG also allows you to adjust the image quality (resolution) by adjusting the sliding tab
between 1 and 100, 1 being the lowest quality and 100 the highest.
When possible, use the highest quality; when not, speed up image transfers by using a
lower quality setting. Adjustments for this setting will depend on your specific hardware/
software limitations.
