ImageAttributes.ClearOutputChannel Method

Definition

Namespace:

System.Drawing.Imaging

Assembly:

System.Drawing.Common.dll

Clears the CMYK (cyan-magenta-yellow-black) output channel setting.

Overloads

ClearOutputChannel()	Clears the CMYK (cyan-magenta-yellow-black) output channel setting for the default category.
ClearOutputChannel(ColorAdjustType)	Clears the (cyan-magenta-yellow-black) output channel setting for a specified category.

ClearOutputChannel()

Clears the CMYK (cyan-magenta-yellow-black) output channel setting for the default category.

public:
 void ClearOutputChannel();

public void ClearOutputChannel ();

member this.ClearOutputChannel : unit -> unit

Public Sub ClearOutputChannel ()

Remarks

An ImageAttributes object maintains color and grayscale settings for five adjustment categories: default, bitmap, brush, pen, and text. For example, you can specify an output channel for the default category and a different output channel for the bitmap category.

The default color-adjustment and grayscale-adjustment settings apply to all categories that do not have adjustment settings of their own. For example, if you never specify any adjustment settings for the bitmap category, the default settings apply to the bitmap category.

ClearOutputChannel(ColorAdjustType)

Clears the (cyan-magenta-yellow-black) output channel setting for a specified category.

public:
 void ClearOutputChannel(System::Drawing::Imaging::ColorAdjustType type);

public void ClearOutputChannel (System.Drawing.Imaging.ColorAdjustType type);

member this.ClearOutputChannel : System.Drawing.Imaging.ColorAdjustType -> unit

Public Sub ClearOutputChannel (type As ColorAdjustType)

Parameters

type

ColorAdjustType

An element of ColorAdjustType that specifies the category for which the output channel setting is cleared.

Remarks

An ImageAttributes object maintains color and grayscale settings for five adjustment categories: default, bitmap, brush, pen, and text. For example, you can specify an output channel for the default category and a different output channel for the bitmap category.

The default color-adjustment and grayscale-adjustment settings apply to all categories that do not have adjustment settings of their own. For example, if you never specify any adjustment settings for the bitmap category, the default settings apply to the bitmap category.

As soon as you specify a color-adjustment or grayscale-adjustment setting for a certain category, the default adjustment settings no longer apply to that category. For example, suppose you specify an output channel and an adjustment matrix for the default category. If you set the output channel for the bitmap category by calling the SetOutputChannel method, the default output channel will not apply to bitmaps. If you later clear the bitmap output channel by calling the ClearOutputChannel method, the bitmap category will not revert to the default output channel; rather, the bitmap category will have no output channel setting. Similarly, the bitmap category will not revert to the default color-adjustment matrix; rather, the bitmap category will have no color-adjustment matrix.
