BarcodeReaderReadBarcodesFromMultiFrameTiffInCropArea Method (Image, Rectangle, BarcodeEncoding, BarcodeReaderBarcodeRotationCorrection, BarcodeReaderBarcodeImageCorrection)

Reads barcodes from a specified rectangular area within each frame of a multi-page image. Multi-Frame Tiff and animated Gif formats supported.

Features granular settings for developer control to balance performance against accuracy for their given use case.

Overloads of this method accept InputImage as string file paths as well as Image, Bitmap and Stream types.

Namespace:  IronBarCode
Assembly:  IronBarCode (in IronBarCode.dll) Version: 4.0.1.22591 (4.0.1.0)
Syntax
public static PagedBarcodeResult[] ReadBarcodesFromMultiFrameTiffInCropArea(
	Image InputImage,
	Rectangle CropArea,
	BarcodeEncoding BarcodeFormat = BarcodeEncoding.All,
	BarcodeReaderBarcodeRotationCorrection RotationCorrection = BarcodeReaderBarcodeRotationCorrection.Low,
	BarcodeReaderBarcodeImageCorrection ImageCorrection = BarcodeReaderBarcodeImageCorrection.None
)

Parameters

InputImage
Type: System.DrawingImage
Multi frame image as a Image.
CropArea
Type: System.DrawingRectangle
The area of each image frame in which to scan for barcodes. A Rectangle measured in pixels.
BarcodeFormat (Optional)
Type: IronBarCodeBarcodeEncoding
The barcode encoding types to read from the image frames. By default all supported barcodes types are scanned for. Choosing one or more specific Barcode formats will improve performance significantly.
RotationCorrection (Optional)
Type: IronBarCodeBarcodeReaderBarcodeRotationCorrection
Setting to allow the barcode reader to detect and accurately read barcodes which are rotated or skewed with perspective using a Hough Transform. Default tolerance is 10 Degrees of rotation; higher levels use more CPU.
ImageCorrection (Optional)
Type: IronBarCodeBarcodeReaderBarcodeImageCorrection
Setting which can clean noisy input images by allowing barcodes to be distinguished from the rest of the image. CPU Intensive.

Return Value

Type: PagedBarcodeResult
An Array of PagedBarcodeResult. Array length will be zero if no barcodes were found.
