| symbologies | property |
public var symbologies:Array
An array containing the symbologies you want to scan for. Limiting this to just the codes your application is interested in will improve performance of the scanner.
Note: To enable all symbologies, just leave this array empty.
The default is just QRCODE
| x_density | property |
public var x_density:int = 1
The scanner works by making scan passes across the pixel rows and columns of the image.
The density of the passes is configured at the scanner as a pixel stride for each axis.
Setting the stride value to 0 completely disables scanning in that direction.
This is very useful when reading linear codes with a visual alignment guide -
scanning parallel to the bars is a waste of cycles which may be better applied
to support higher resolution or increased density of scans across the symbol.
Note that some 2-D symbologies (QR Code) require scans in both directions.
In general, 2 to 4 is a good target for the stride setting, unless you have very high or low resolution images.
For high resolution QR Codes, we suggest setting this to 1
This x_density controls the number of pixel rows that are skipped between successive horizontal scan passes.
| y_density | property |
public var y_density:int = 1
This y_density controls the number of pixel columns that are skipped between successive vertical scan passes.
