MaximumFilter Class

This class enables you to apply maximum filter (also known as erosion).

Namespace: Aurigma.GraphicsMill.Transforms
Assembly: Aurigma.GraphicsMill (in Aurigma.GraphicsMill.dll)

Syntax

Visual Basic

Public NotInheritable Class MaximumFilter _
	Inherits BitmapTransform

public sealed class MaximumFilter : BitmapTransform

Remarks

Maximum filter is a non-linear filter which works in the following way: for each pixel it searches pixel with maximum brightness in "running window" of the radius specified with Radius property. This pixel is copied to the result bitmap.

That's why if you apply this filter on the image with has black objects on white background (for example text), they will be erosed.

Supported Pixel Formats

Member Name	Description
Format1bppIndexed	1 bit per pixel. Indexed.
Format8bppGrayScale	8 bits per pixel. Grayscale. 8 bits are used for luminosity level.
Format16bppGrayScale	16 bits per pixel. Grayscale. All 16 bits are used for luminosity level (extended pixel format).
Format16bppAGrayScale	16 bits per pixel. Grayscale with alpha channel. 8 bits are used for alpha channel and other 8 bits are used for luminosity level.
Format32bppAGrayScale	32 bits per pixel. Grayscale with alpha channel. 16 bits are used for alpha channel and other 16 bits are used for luminosity level (extended pixel format).
Format24bppRgb	24 bits per pixel. RGB. 8 bits each are used for the red, green, and blue components.
Format32bppRgb	32 bits per pixel. RGB. 8 bits each are used for the red, green, and blue components. The rest 8 bits are unused.
Format32bppArgb	32 bits per pixel. RGB with alpha channel. 8 bits each are used for the alpha, red, green, and blue components.
Format48bppRgb	48 bits per pixel. RGB. 16 bits each are used for the red, green, and blue components (extended pixel format).
Format64bppArgb	64 bits per pixel. RGB with alpha channel. 16 bits each are used for the alpha, red, green, and blue components (extended pixel format).
Format32bppCmyk	32 bits per pixel. CMYK. 8 bits each are used for the cyan, magenta, yellow, and black components.
Format64bppCmyk	64 bits per pixel. CMYK. 16 bits each are used for the cyan, magenta, yellow, and black components (extended pixel format).
Format80bppAcmyk	80 bits per pixel. CMYK with alpha channel. 16 bits each are used for the alpha, cyan, magenta, yellow, and black components (extended pixel format).
