CMFCToolBarImages::GrayImages
Grays the toolbar images to make them look disabled.
BOOL GrayImages(
int nGrayImageLuminancePercentage
);
Parameters
- [in] nGrayImageLuminancePercentage
Luminance percentage.
Return Value
TRUE if images in the collection were grayed successfully; otherwise FALSE.
Remarks
This method modifies the toolbar images by averaging the red, green, and blue components of each pixel and multiplying the result by nGrayImageLuminancePercentage divided by 100. If nGrayImageLuminancePercentage is zero or negative, the default value of 130 is used instead.
Hinweis
If you want to undo the change, you must reload the images from the source. You can do this by calling CMFCToolBarImages::Load or CMFCToolBarImages::UpdateImage (only for user-defined images), or by calling CMFCToolBarImages::Clear and adding the images again by calling CMFCToolBarImages::AddIcon or CMFCToolBarImages::AddImage.
