Template Name:
Barcode Format:
Specify the barcode type(s) to read. Defaults to all supported types.
Select Format Settings:
Select Pages:

Select Regions:
Min Image Dimension to Filter Text (pixel):

Max Image Dimension:
Sets the threshold value of the image dimension in pixels. If the dimension 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 decoding. Otherwise, it will perform barcode decoding on the original image.
Region Predetection Mode:

Min Image Dimension to Pre-detect Region (pixel):
Read DPM Codes:

Forward Image Reference Count:

Backward Image Reference Count:


Define Rows and Columns of the Matrix:
Barcode Invert Mode:
Gray Equalization Sensitivity:
Image Type:
AutoDetection: Automatically detects whether images are Documents or Photos.
Document: Mainly for documents with texts in grayscale or B&W.
Photo: Mainly for photos with flash, shadow, perspective issues.
Maximum barcodes per page:
Sets the maximum number of barcodes to read per page.
Timeout per page (ms):
Sets the maximum amount of time (in milliseconds) it should spend searching barcodes per page.
Scale Down Threshold:
The threshold of the shorter edge of the barcode image. Once exceeds, the image will shrink. It's mainly for large images to speed up the process.

Localization Mode:
Auto: Auto selects the optimized algorithm for locating barcodes.
Lines: Localizes barcodes by searching for groups of lines.
Statistics: Localizes barcodes by searching for groups of contiguous black-white regions.
LinesPriorToStatistics: Uses both Lines and Statistics mode, but prefers to use Lines mode firstly.
StatisticsPriorToLines: Uses both Lines and Statistics mode, but prefers to use Statistics mode firstly.
None: Disables localization. In this mode, it will directly decode the image without localization.
The higher the value is, the more effort the library will take to decode blurred barcodes.
