Outline and description of classes and enumerations.

Classes

 ClassDescription
AutoBinaryActivity Applies binary segmentation to the image using an automatically calculated threshold based on a two-peak method of statistical analysis of the histogram. This command is available in the Document/Medical Toolkits.
AutoCropActivity Trims the current image, removing blank space around the edges.
AverageActivity Changes the color of each pixel in an image to the average color of the pixels in its neighborhood. This results in a blur effect.
BinaryActivity Imposes a binary filter on an image. This activity is available in the Document/Medical Toolkits.
BorderRemoveActivity Removes the black borders in a 1-bit black and white image. This activity is available in the Document/Medical Toolkits.
ColorResolutionActivity Converts an image from any bits-per-pixel to any bits-per-pixel.
CropActivity Crops the image, resulting in an image that is the size of the specified rectangle.
DeskewActivity Rotates the specified image to straighten it. This activity is typically used to automatically straighten scanned images. This activity is available in the Document\Medical Toolkits.
DespeckleActivity Removes speckles from an image. Typically, this activity is used to clean up scanned images (such as FAX images). This activity is available in the Document/Medical Toolkits.
DotRemoveActivity Finds and removes dots and specks of various sizes. This method is available in the Document/Medical Toolkits.
DynamicBinaryActivity Converts an image into a black and white image without changing its bits per pixel by using a local threshold value for each pixel of the image. This function is useful for pre-processing images for the purpose of improving barcode recognition results.
EdgeDetectorActivity Applies the specified edge filter to an image. This activity is available in the Document Toolkits.
FlipActivity Flips an image from top to bottom or from left to right.
HalftoneActivity Converts a 1-, 4-, 8-, 16-, 24-, or 32-bit image to a halftoned image, with a specified pattern of rotation. A halftoned image is a 1-bit image that has been dithered for black and white printing or display.
HighQualityRotateActivity Perform high quality rotation on a black and white image.
HistogramEqualizeActivity Linearizes the number of pixels in an image based on the specified color space. This can be used to bring out the detail in dark areas of an image. This activity is useful for pre-processing images for the purpose of improving barcode recognition results.
HolePunchRemoveActivity Finds and removes hole punches. This activity is available in the Document/Medical Toolkits.
ImageProcessingBaseActivity The ImageProcessingBaseActivity class is the base class for all LEADTOOLS WF image processing activities.
IntensityDetectActivity Applies binary segmentation to an image by filtering a specific image to detect colors in a specific intensity range, in a specific color channel(s).
InvertActivity Inverts the colors in the specified image, giving it the appearance of a photographic negative.
InvertedPageActivity Checks and auto-correct an inverted image.
InvertedTextActivity Finds and modifies areas of inverted text in a 1-bit black and white image. This command is available in the Document/Medical Toolkits.
LineRemoveActivity Removes horizontal and vertical lines in a 1-bit black and white image. This activity is available in the Document/Medical Toolkits.
MaximumActivity Erodes dark objects by the specified amount. This activity is available in the Document/Medical Toolkits.
MedianActivity Changes the color of each pixel in an image to the median color of the pixels in its neighborhood. This is similar to the AverageActivity activity, but it is used for noise reduction, rather than a blur effect.
MinimumActivity Dilates dark objects by the specified amount.This activity is available in the Document/Medical Toolkits.
PredefinedBinaryActivity Imposes a predefined binary filter on an image. This activity is available in the Document/Medical Toolkits.
PredefinedSpatialActivity Imposes a predefined spatial filter on an image. This activity is available in the Document/Medical Toolkits.
ResizeActivity Resizes the image passed to it according to the Width and Height values passed to it.
ResizeInterpolateActivity Applies different kinds of algorithms on images to resize them to the desired size.
RotateActivity Rotates an image by the specified number of degrees.
SharpenActivity Increases or decreases the sharpness of a specific image.
SmoothActivity Smoothes the bumps and fills in the nicks of a 1-bit black and white image. This activity is available in the Document/Medical Toolkits.
SpatialActivity Imposes a spatial filter on an image. This activity is available in the Document/Medical Toolkits.
StatisticsInformationActivity Returns statistical information about the image.
UnsharpMaskActivity Sharpens the image by applying the unsharp mask.

Enumerations

 EnumerationDescription
BinaryFilterCommandPredefined Enumerated values that represent the predefined binary filter to use.
BorderRemoveBorderFlags Indicates which border to remove
BorderRemoveCommandFlags Enumerated values that determine the behavior of the border removal process.
ColorResolutionCommandPaletteFlags Palette options for the ColorResolutionActivity.PaletteFlags property.
DeskewCommandBackgroundOptions Flags that indicate which background color to use.
DeskewCommandDeskewOptions Flags that indicate whether to deskew the image after the method finds the skew angle.
DeskewCommandDetectionType Flags that indicate the detection technique to use.
DeskewCommandImageType Flags that indicate whether the image contains mostly text, or text and pictures.
DeskewCommandInterpolationType Flags that specify which type of interpolation to use.
DeskewCommandPreProcessingOptions Flags that indicate whether to preprocess the image.
DeskewCommandRotationSpeed Flags that indicate whether to use normal or fast rotation speed. Normal results in high quality. Fast results in moderate quality and is only intended for 1-bit images.
DeskewCommandThresholdOptions Flags that indicate whether to deskew the image if the skew angle is very small.
DotRemoveCommandFlags Flags that determine the behavior of the dot removal process.
EdgeDetectorCommandType Flag that indicates the type of edges to detect.
HalfToneCommandType Enumeration that indicates the type of halftoning to perform.
HighQualityRotateCommandFlags Options for the HighQualityRotateActivity class.
HistogramEqualizeType This enumeration will contain all of the types needed to indicate which color space is selected.
HolePunchRemoveCommandFlags Values that determine the behavior of the hole punch removal process.
HolePunchRemoveCommandLocation Flag that indicates the location within the document where the hole punches are that need to be removed.
IntensityDetectCommandFlags Flag that indicates which channel to process.

This flag has a FlagsAttribute attribute that allows a bitwise combination of its member values.

InvertedPageCommandFlags Options for the InvertedPageActivity class.
InvertedTextCommandFlags Flags that determine the behavior of the inverted text removal process.
LineRemoveCommandFlags Flags that determine the behavior of the line removal process.
LineRemoveCommandType Flag that indicates which lines to remove.
RasterColorChannel Indicates the channel that will be used for image processing methods.
ResizeInterpolateCommandType Represents the algorithm type used in resizing the image.
RotateCommandFlags Flags for the RotateActivity.Flags property.
