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 .
