Document Image Processing

Overview

These are the properties and methods related to document image processing. These properties and method may not be exclusive to the document image processing as sometimes there is overlap with color image processing.

Properties

BackColor	Gets and sets the background color of the control window.
IPBinarizeBlur	Gets the blur value set by the last call to the Binarize or AutoBinarize method.
IPBinarizeEccentricity	Gets the eccentricity value set by the last call to the Binarize or AutoBinarize method.
IPBinarizeGridAngle	Gets the grid angle value set by the last call to the Binarize or AutoBinarize method.
IPBinarizeGridPitch	Gets the grid pitch value set by the last call to the Binarize or AutoBinarize method.
IPBinarizeHighThreshold	Gets the high threshold set by the last call to the Binarize or AutoBinarize method.
IPBinarizeLceFactor	Gets the local contrast enhancement value set by the last call to the Binarize or AutoBinarize method.
IPBinarizeLowThreshold	Gets the low threshold set by the last call to the Binarize or AutoBinarize method.
IPBinarizeMode	Gets the binarize mode set by the last call to the Binarize or AutoBinarize method.
IPBlankPageDetected	Gets the result of the last call to DocumentBlankPageDetect.
IPConfidence	Indicates level of certainty that results are correct.
IPCountOfLinesFound	Gets the number of lines found during execution of the DocumentLineRemoval method.
IPCountOfObjectsFound	Gets the count of the objects found during execution of the DocumentBlobRemoval method.
IPCountOfSpecsFound	Gets the count of the specs found during execution of the DocumentDespeckle method.
IPImageWasModified	Gets an indicator if an image was altered by one of the Document processing methods.
IPRotationalAngle	Gets the rotation angle (in degrees) used by the last call to either the Rotate method or DocumentDeskew method.
IPVariation	Gets the amount of variation detected in the skew of the image, when the DocumentDeskew method is executed.

Methods

AutoBinarize	Automatically converts 8-bit and 24-bit images into 1-bit monochrome or 8-bit grayscale images respectively.
Binarize	Converts 8-bit and 24-bit images into a 1-bit monochrome or 8-bit grayscale output image, respectively.
Crop	Crops the current image to the specified size.
CropBorder	Performs border removal by automatically cropping the edges of the current DIB.
Deskew	Corrects an image that is skewed.
Despeckle	Filters the image using a filter that attempts to eliminate noise in the image.
Dilate	Dilates the current image using a 3x3 maximum filter.
DocumentBlankPageDetect	Examines a rectangle on an image, determining if the page is considered blank, based on the amount of data on the page.
DocumentBlobRemoval	Locates and removes large black objects in images such as binder punch holes.
DocumentBorderCrop	Crops the borders of documents.
DocumentDeskew	Automatically detects and removes skew from current 1-bit depth images.
DocumentDespeckle	Detects and removes specks from the current image.
DocumentDilate	Examines pixels in the current image and expands the black ones by given amount in given direction.
DocumentErode	Removes the black pixels in the current image by the given amount in the given direction.
DocumentLineRemoval	Automatically detects and removes lines from the current image.
DocumentShear	Shears current image clockwise or counter-clockwise.
DocumentZoomSmooth	Replaces current 1 bit-per-pixel images with an image whose width and height have been doubled and whose pixels have been smoothed.
Erode	Erodes the current DIB using a 3x3 minimum filter.
Flip	Flips the current image from top to bottom.
Median	Utilizes a 3x3 median filter to eliminate noise in the current image.
Mirror	Rotates the current image 180 degrees, then flips it to create a mirror image.
Negate	Creates a color negative of the current image.
Resize	Resizes the current image.
ResizeEx	Resizes the current image according to the algorithm specified by enumResizeType enumerator.
Rotate	Rotates the current image.
Undo	Undo the action of the previous image processing method if the UndoEnabled property was set True prior to performing the method.
