ImageAttributes class

Applies to: desktop apps only

An ImageAttributes object contains information about how bitmap and metafile colors are manipulated during rendering. An ImageAttributes object maintains several color-adjustment settings, including color-adjustment matrices, grayscale-adjustment matrices, gamma-correction values, color-map tables, and color-threshold values.

Members

The ImageAttributes class inherits from GdiplusBase. ImageAttributes also has these types of members:

Constructors

The ImageAttributes class has these constructors.

ConstructorDescription
ImageAttributes::ImageAttributes

Creates an ImageAttributes::ImageAttributes object. This is the default constructor.

 

Methods

The ImageAttributes class has these methods.

MethodDescription
ImageAttributes::ClearBrushRemapTable

The ImageAttributes::ClearBrushRemapTable method clears the brush color-remap table of this ImageAttributes object.

ImageAttributes::ClearColorKey

The ImageAttributes::ClearColorKey method clears the color key (transparency range) for a specified category.

ImageAttributes::ClearColorMatrices

The ImageAttributes::ClearColorMatrices method clears the color-adjustment matrix and the grayscale-adjustment matrix for a specified category.

ImageAttributes::ClearColorMatrix

The ImageAttributes::ClearColorMatrix method clears the color-adjustment matrix for a specified category.

ImageAttributes::ClearGamma

The ImageAttributes::ClearGamma method disables gamma correction for a specified category.

ImageAttributes::ClearNoOp

The ImageAttributes::ClearNoOp method clears the NoOp setting for a specified category.

ImageAttributes::ClearOutputChannel

The ImageAttributes::ClearOutputChannel method clears the CMYK output channel setting for a specified category.

ImageAttributes::ClearOutputChannelColorProfile

The ImageAttributes::ClearOutputChannelColorProfile method clears the output channel color profile setting for a specified category.

ImageAttributes::ClearRemapTable

The ImageAttributes::ClearRemapTable method clears the color-remap table for a specified category.

ImageAttributes::ClearThreshold

The ImageAttributes::ClearThreshold method clears the threshold value for a specified category.

ImageAttributes::Clone

The ImageAttributes::Clone method makes a copy of this ImageAttributes object.

ImageAttributes::GetAdjustedPalette

The ImageAttributes::GetAdjustedPalette method adjusts the colors in a palette according to the adjustment settings of a specified category.

ImageAttributes::GetLastStatus

The ImageAttributes::GetLastStatus method returns a value that indicates the nature of this ImageAttributes object's most recent method failure.

ImageAttributes::Reset

The ImageAttributes::Reset method clears all color- and grayscale-adjustment settings for a specified category.

ImageAttributes::SetBrushRemapTable

The ImageAttributes::SetBrushRemapTable method sets the color remap table for the brush category.

ImageAttributes::SetColorKey

The ImageAttributes::SetColorKey method sets the color key (transparency range) for a specified category.

ImageAttributes::SetColorMatrices

The ImageAttributes::SetColorMatrices method sets the color-adjustment matrix and the grayscale-adjustment matrix for a specified category.

ImageAttributes::SetColorMatrix

The ImageAttributes::SetColorMatrix method sets the color-adjustment matrix for a specified category.

ImageAttributes::SetGamma

The ImageAttributes::SetGamma method sets the gamma value for a specified category.

ImageAttributes::SetNoOp

The ImageAttributes::SetNoOp method turns off color adjustment for a specified category. You can call ImageAttributes::ClearNoOp to reinstate the color-adjustment settings that were in place before the call to ImageAttributes::SetNoOp.

ImageAttributes::SetOutputChannel

The ImageAttributes::SetOutputChannel method sets the CMYK output channel for a specified category.

ImageAttributes::SetOutputChannelColorProfile

The ImageAttributes::SetOutputChannelColorProfile method sets the output channel color-profile file for a specified category.

ImageAttributes::SetRemapTable

The ImageAttributes::SetRemapTable method sets the color-remap table for a specified category.

ImageAttributes::SetThreshold

The ImageAttributes::SetThreshold method sets the threshold (transparency range) for a specified category.

ImageAttributes::SetToIdentity

The ImageAttributes::SetToIdentity method sets the color-adjustment matrix of a specified category to identity matrix.

ImageAttributes::SetWrapMode

The ImageAttributes::SetWrapMode method sets the wrap mode of this ImageAttributes object.

 

Remarks

The colors in an image can be manipulated during rendering. They can be corrected, darkened, lightened, removed, and so on. To apply such manipulations, initialize an ImageAttributes object and pass the address of that ImageAttributes object (along with the address of an Image object) to the Graphics::DrawImage method.
