| Class | Description | |
|---|---|---|
 | 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. |
| Enumeration | Description | |
|---|---|---|
 | 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. |
