Color Resolution
Converts the image from any bits-per-pixel to any bits-per-pixel, letting you specify the palette to use. Also, when converting to 16-bits per pixel or higher, you can specify RGB or BGR color order.
Options:
Bits Per Pixel - 1 to 8, 12, 16, 24, 32
Color Order - Blue-Green-Red, Red-Green-Blue
Colored Gray Filter
Converts the processed images to grayscale, then enhances the color components based on the specified parameters. You can use the Colored Gray Filter to give images an old-fashioned look by adding a blue or brown color. Red Value Weight + Green Value Weight + Blue Value Weight must equal 1000. The software divides each value by 1000.
For example, if you set the Red Value Weight set to 500, the Green Value Weight to 250, and the Blue Value Weight to 250, the red value of each pixel gets 50% of the weight when determining the grayscale value. The green value gets 25% of the weight, and the blue value gets 25% of the weight when determining the grayscale value. This highlights or enhances the red in the bitmap, prior to conversion to grayscale. Upon conversion to grayscale, the red, green, and blue components of the output pixel are the same. Call this value G. Therefore, the RGB values for the pixel would be (G, G, G).
Once the grayscale value for the pixel has been obtained, the red component of the output pixel can be further modified using the Red Weight Factor Modifier value. The equation for this is as follows:
Goutput-red = G + G * Red Weight Factor Modifier / 1000
The green and blue components are found similarly, using the Green Weight Factor Modifier and the Blue Weight Factor Modifier values, respectively.
The Red Weight Factor Modifier, Green Weight Factor Modifier, and Blue Weight Factor Modifier values can be negative. A negative value results in a decrease in pixel intensity. A positive value results in an increase in pixel intensity.

Flip
Flips the image from top to bottom.
Options: None
Gamma Correct
Adjusts the intensity of colors in the image by changing the gamma constant that is used to map the intensity values. Intensity values ideally follow a logarithmic progression, because the eye perceives changes in intensity as being equal when the ratio of change is equal. For example, we would see a change from 0.1 to 0.2 as being equal to a change from 0.2 to 0.4. Gamma is a standard constant that is used to calculate the progression. For most CRTs, the gamma constant is in the range of 2.2 to 2.5. Because this value is an unsigned integer, the value is 100 times the actual gamma value. For example, you must enter 235 in the Value box to set a gamma value of 2.35.
Options: Value - 1 to 499
Gaussian Blur
Applies a type of filter that is especially good for grainy or speckled images. In this type of effect, pixel weights are not equal. They decrease from kernel center to edges according to a bell-shaped curve called Gaussian.
Each pixel in the image being processed is blurred based on neighborhood pixels. The Size parameter determines the size of the neighborhood to consider when blurring a pixel. The result is a blurred version of the original image.
Options: Size, 1 to 50

Half-tone
Converts a 1-, 4-, 8-, 16-, 24-, or 32-bit image to a halftoned bitmap. A halftoned bitmap is a 1-bit bitmap that has been dithered for black and white printing or display. If the bitmap is originally 1-bit but is not black and white, this method changes it to black and white.
Options: Angle - -360 to 360
HistoContrast
Increases or decreases the contrast of the image, using a histogram to determine the median brightness. This method finds the median brightness of the image; then brightens the pixels with values above the median and darkens the pixels with values below the median. This is more sophisticated, but slower, than the Contrast feature, which uses the middle possible value, 128, rather than finding the actual median.
Options: Percentage - -100 to 100
Hole Punch Remove
This feature detects and removes hole punches, common in scanned documents. The feature works only on 1-bit black and white images. Hole punch configurations may consist of 2 or more holes.

Intensity Detect
Filters the image to detect colors in a specified intensity range. Intensity levels range from 0 to 255 for each color plane, red, green, and blue. This feature processes each plane separately. If a value falls within the range, it is raised to 255, and if it falls outside the range, it is lowered to 0.
Options:
Low - 0 to 255
High - 0 to 255
In Color:
The color used to fill those pixels having an intensity value between Low and High. This setting has no effect if the Channel parameter is set to MASTER. If for example the Channel is set to RED, then the red component of In Color will be used to fill the pixels having a red component value between Low and High.
Out Color:
The color used to fill those pixels having an intensity value less than Low or greater than High. This parameter has no effect if the Channel setting is MASTER. If for example the Channel setting is set to RED, then the red component of Color Out will be used to fill the pixels having a red component value less than Low or greater than High.
Channel:
MASTER = 0 (Grayscale Channel)
RED = 1 (Red Channel)
GREEN = 10 (Green Channel)
BLUE = 100 (Blue Channel)

To fine-tune the performance of this feature, try modifying the values for Wall, Gap Length and variance.
Options:
Measure unit:
Remove - Horizontal, Vertical

Each pixel is replaced with the maximum value of its neighborhood.
Options Sample Size - 3 to 11
Median
Changes the color of each pixel in the image to the median color of pixels in its neighborhood. This is similar to the Average method, but it is used for noise reduction, rather than a blur effect. You control the effect by specifying the size of the neighborhood that is used for calculating the median value. For 8x8, pass a value of 8.
Options: Sample Size - 3 to 11
Min Filter
Dilates dark objects by the amount that you specify. This is a more controlled version of the omni-directional dilation filter that you can set with the Binary Filter option.

Rotate
Rotates the image by the degree specified, and lets you define the background color to be uncovered.
Uses the center of the bitmap as the center of rotation. It can rotate the bitmap clockwise or counterclockwise up to 360 degrees in hundredth-of-a-degree increments. It can resize the bitmap to accommodate the rotated height and width, or it can retain the original height and width, cropping the bitmap as necessary. It lets you specify the background color to fill any new area created by the rotation. Note - The only images that are interpolated are 8-bit grayscale images. For best results, all gray values should be in the image's palette. If the rotation doesn't give the expected results, you can call Grayscale - 8 to change the image into a proper grayscale image. 12-bit and 16-bit grayscale images that don't have a palette. Grayscale images can have a palette if they have been loaded from certain DICOM images 16-bit color images 24-bit, 32-bit, 48-bit and 64-bit color images.
Options:
Clockwise Angle
Resize

Saturation
Increases or decreases the saturation of colors in the image. Negative values decrease the saturation of colors. Positive values increase the saturation. The saturation level is increased or decreased by a percentage of its present saturation level. For example, an increase of 20% of the current saturation level L raises the new saturation level L1 to a value of L + 0.20 * L. Likewise, increasing the saturation level 100% doubles the saturation level, L1 = L + 1.0 * L. Decreasing the saturation level 100% sets the new saturation level to 0. This process is carried out for every pixel.
