Dynamsoft Barcode Readerv7.5 Some new parameter configurations have been introduced , For example, center positioning bar code 、 Binary mode, etc . Let's take a look at some of the highlights of the new features .
to update
- Added right QR Code Model 1(QR Code Old versions of the specification ) Support for . It can be done by JSON Set in the template file FormatSpecification.EnableQRCodeModel1 To enable it .
- Added a new location mode LM_CENTRE To locate barcodes from the center , If the barcode is in the center of the image , It can improve the positioning speed . You can set the structure PublicRuntimeSettings-> LocalizationModes-> LM_CENTRE To enable it .
- Added a new binarization pattern BM_THRESHOLD To set up BinarizationThreshold value , This value is used to convert a grayscale image to a binary image .
- by UPC_A,UPC_E,EAN_8 and EAN_13 The structure of the code OneDCodeDetails Added startPatternRange,middlePatternRange and endPatternRange attribute .
- by RegionPredetectionMode.RPM_GENERAL_RGB_CONTRAST and RegionPredetectionMode.RPM_GENERAL_GRAY_CONTRAST The following new parameters have been added :
- RelativeBarcodeRegions: Set the barcode area relative to the pre detection area .
- ForeAndBackgroundColours: Specifies a set of ( Or multiple groups ) Foreground and background colors .
- AspectRatioRange: Set the height range of the bounding rectangle of the pre detection area .
- HeightRange: Set the width range of the bounding rectangle of the pre detection area .
- WidthRange: Set the aspect ratio range of the bounding rectangle of the pre detection area .
improve
- The binarization process of one-dimensional bar code region is optimized .
- It improves the decoding accuracy of one-dimensional bar code .
- Decoding speed has been improved 5%-20%.
- Using the damaged finder mode improves the decoding accuracy of the data matrix code .
Repair
- Fixed an error where the coordinates of the barcode were not calculated correctly in some cases .
