Overview |
Refer to Combining Images. |
Remarks
(DigitalPaint only) Combines image data from two bitmaps with feathering, by combining the two bitmaps with a variable opacity that depends on a fade mask. This method is only available in the DigitalPaint toolkits.
To combine two bitmaps with a fixed opacity, use the AlphaBlend method.
The FeatherAlphaBlend method achieves feathering between two bitmaps by using variable opacity values, obtained from the fade mask contained in pRasterMask.
To create a bitmap that contains a fade mask, use the CreateFadedMask method.
This method supports 12 and 16-bit grayscale images and 48 and 64-bit color images. Support for 12 and 16-bit grayscale images and 48 and 64-bit color images is available only in the Document/Medical toolkits.
This method does not support signed data images. It returns the error code ERROR_SIGNED_DATA_NOT_SUPPORTED if a signed data image is passed to this method.
