Class QualitySettings

java.lang.Object
com.aspose.barcode.barcoderecognition.QualitySettings
All Implemented Interfaces:
android.os.Parcelable
public final class QualitySettings extends Object implements android.os.Parcelable

QualitySettings allows to configure recognition quality and speed manually. You can quickly set up QualitySettings with embedded presets: HighPerformance, NormalQuality, HighQuality, MaxQuality or you can manually configure separate options. Default value of QualitySettings is NormalQuality. 

 This sample shows how to use QualitySettings with BarCodeReader
 
 //set HighPerformance recogition mode
 BarCodeReader reader = new BarCodeReader("test.png", DecodeType.CODE_39_EXTENDED, DecodeType.CODE_128);
 {
     reader.setQualitySettings(QualitySettings.getHighPerformance());
     for(BarCodeResult result : reader.readBarCodes())
         System.out.println(result.getCodeText());
 }
 //set HighQuality recognition mode
 BarCodeReader reader = new BarCodeReader("test.png", DecodeType.CODE_39_EXTENDED, DecodeType.CODE_128);
 {
     reader.setQualitySettings(QualitySettings.getHighQuality());
     for(BarCodeResult result : reader.readBarCodes())
         System.out.println(result.getCodeText());
 }
 //set HighPerformance recogition mode for low sized barcodes
 BarCodeReader reader = new BarCodeReader("test.png", DecodeType.CODE_39_EXTENDED, DecodeType.CODE_128);
 {
     reader.setQualitySettings(QualitySettings.getHighPerformance());
     reader.getQualitySettings().setXDimension(XDimensionMode.SMALL);
     for(BarCodeResult result : reader.readBarCodes())
         System.out.println(result.getCodeText());
 }
 //set HighPerformance recogition mode for low quality barcodes
 BarCodeReader reader = new BarCodeReader("test.png", DecodeType.CODE_39_EXTENDED, DecodeType.CODE_128);
 {
     reader.setQualitySettings(QualitySettings.getHighPerformance());
     reader.getQualitySettings().setBarcodeQuality(BarcodeQualityMode.LOW);
     for(BarCodeResult result : reader.readBarCodes())
         System.out.println(result.getCodeText());

    • getDeconvolution

      public DeconvolutionMode getDeconvolution()

      Deconvolution (image restorations) mode which defines level of image degradation.

Because we cannot detect image function which corrupt the image, we have to check most well know functions like sharp or mathematical morphology.

      Value: Deconvolution mode which defines level of image degradation.

    • setDeconvolution

      public void setDeconvolution(DeconvolutionMode value)

      Deconvolution (image restorations) mode which defines level of image degradation. Originally deconvolution is a function which can restore image degraded (convoluted) by any natural function like blur, during obtaining image by camera. Because we cannot detect image function which corrupt the image, we have to check most well know functions like sharp or mathematical morphology.

      Value: Deconvolution mode which defines level of image degradation.
