QualitySettings

QualitySettings class

Namespace: Aspose.Barcode.Recognition

QualitySettings allows to configure recognition quality and speed manually. You can quickly set up QualitySettings by embedded presets: HighPerformance, NormalQuality, HighQuality, MaxBarCodes or you can manually configure separate options. Default value of QualitySettings is NormalQuality. This sample shows how to use QualitySettings with BarCodeReader

Properties

Name	Static	Read/Write	Description
AllowIncorrectBarcodes	No	Read/Write	Allows engine to recognize barcodes which has incorrect checksumm or incorrect values. Mode can be used to recognize damaged barcodes with incorrect text.
BarcodeQuality	No	Read/Write	Mode which enables methods to recognize barcode elements with the selected quality. Barcode element with lower quality requires more hard methods which slows the recognition.
ComplexBackground	No	Read/Write	Mode which enables or disables additional recognition of color barcodes on color images.
Deconvolution	No	Read/Write	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.
HighPerformance	Yes	Read-only	HighPerformance recognition quality preset. High quality barcodes are recognized well in this mode.
HighQuality	Yes	Read-only	HighQuality recognition quality preset. This preset is developed for low quality barcodes.
InverseImage	No	Read/Write	Mode which enables or disables additional recognition of barcodes on images with inverted colors (luminance).
MaxQuality	Yes	Read-only	MaxQuality recognition quality preset. This preset is developed to recognize all possible barcodes, even incorrect barcodes. Value: MaxQuality recognition quality preset.
MinimalXDimension	No	Read/Write	Minimal size of XDimension in pixels which is used with UseMinimalXDimension.
NormalQuality	Yes	Read-only	NormalQuality recognition quality preset. Suitable for the most of barcodes
XDimension	No	Read/Write	Recognition mode which sets size (from 1 to infinity) of barcode minimal element: matrix cell or bar.
