FeatherAlphaBlend method (Main Control)

Visual Basic example
Visual C++ 5.0 example

Syntax short FeatherAlphaBlend(float fLeft, float fTop, float fWidth, float fHeight, OLE_HANDLE hBitmapSrc, float fSrcLeft, float fSrcTop, OLE_HANDLE hBitmapMask);

Overview: Refer to Combining Images.

Remarks

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 referenced by hBitmapMask.

To create a bitmap that contains a fade mask, use the CreateFadedMask method.

This method supports 12 and 16-bit grayscale 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.
