This class allows you making opaque objects on the image to glow.

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

Syntax

Visual Basic

Public NotInheritable Class Glow _
	Inherits BitmapTransform

C#

public sealed class Glow : BitmapTransform

Remarks

When you apply this effect, the image begins glow with specified parameters (taking into account transparent areas of the image). This effect is ideal for creating artistic texts, logos, etc.

You can specify GlowColor as well as parameters which infuence on the glow size and density: Intensity and Radius. Property EnlargeToFit can be used to specify if the transform should increase size of the image to fit the glow or it should truncate the glow which is out of the original image (makes sense to set it to true when you create artistic thumbnails).

Note

If the bitmap does not have an alpha channel (e.g. its pixel format is Format24bppRgb), alpha channel is automatically added. So be aware that pixel format of the output bitmap may differ from the input one.

Thread Safety

Static members of this type are safe for multi-threaded operations. Instance members of this type are safe for multi-threaded operations.

Supported Pixel Formats

Member NameDescription
Format8bppGrayScale8 bits per pixel. Grayscale. 8 bits are used for luminosity level.
Format16bppGrayScale16 bits per pixel. Grayscale. All 16 bits are used for luminosity level (extended pixel format).
Format16bppAGrayScale16 bits per pixel. Grayscale with alpha channel. 8 bits are used for alpha channel and other 8 bits are used for luminosity level.
Format32bppAGrayScale32 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).
Format24bppRgb24 bits per pixel. RGB. 8 bits each are used for the red, green, and blue components.
Format32bppRgb32 bits per pixel. RGB. 8 bits each are used for the red, green, and blue components. The rest 8 bits are unused.
Format32bppArgb32 bits per pixel. RGB with alpha channel. 8 bits each are used for the alpha, red, green, and blue components.
Format48bppRgb48 bits per pixel. RGB. 16 bits each are used for the red, green, and blue components (extended pixel format).
Format64bppArgb64 bits per pixel. RGB with alpha channel. 16 bits each are used for the alpha, red, green, and blue components (extended pixel format).
