ImageAttributes class (gdiplusimageattributes.h)
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.
Inheritance
The ImageAttributes class implements GdiplusBase.
Methods
The ImageAttributes class has these methods.
| 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 cyan-magenta-yellow-black (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::ImageAttributes Creates an ImageAttributes::ImageAttributes object. This is the default constructor. (ImageAttributes.ImageAttributes) |
| ImageAttributes::ImageAttributes Creates an ImageAttributes::ImageAttributes object. This is the default constructor. (overload 2/3) |
| ImageAttributes::ImageAttributes Creates an ImageAttributes::ImageAttributes object. This is the default constructor. (overload 1/3) |
| 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.
