Shadow Class

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

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

Syntax

Visual Basic

Public NotInheritable Class Shadow _
	Inherits BitmapTransform

public sealed class Shadow : BitmapTransform

Remarks

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

You can specify a number of shadow parameters. HorizontalOffset and VerticalOffset specify offset of the shadow relatively the image. ShadowColor means the shadow color. To make shadow looking more realistic, it is blurred. You can set blur Radius (amount of the shadow fuzziness). Property EnlargeToFit can be used to specify if the transform should increase size of the image to fit the shadow or it should truncate the shadow which is out of the original image (makes sense to set it to true when you create artistic thumbnails).

All the coordinates and sizes are measured in units specified with Unit property.

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.

Supported Pixel Formats

Member Name	Description
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).
