ScaleDownThreshold

ScaleDownThreshold is a parameter to specify the threshold for image shrinking. It is defined as below:

Value Type Value Range Default Value
int [512, 0x7fffffff] 2300

Remarks
If the shorter edge size is larger than the given value, the library will calculate the required height and width of the barcode image and shrink the image to that size before localization. Otherwise, it will perform barcode localization on the original image.

Setting Methods

ScaleDownThreshold is supported to be set through RuntimeSetting or JSON template.

As PublicRuntimeSettings Member

ScaleDownThreshold can be set dynamically during runtime as a member of PublicRuntimeSettings struct.
