Syntax

dAlphaBlend(<Destination image> , <Source image> [, <Opacity>])

<Destination image>: Image control or Image, WDPic or picLayer variable

Image in which the merge must be performed. This image can correspond to:
the name of an Image control.
the name of a variable of type Image.
For the blend, this image will be considered as the background image.

<Source image>: Image control or Image, WDPic or picLayer variable

Image to merge. This image can correspond to:
the name of an Image control.
the name of a variable of type Image.

<Opacity>: Optional real

Percentage of opacity that must be applied to <Source image> before performing the blend (100% by default, no opacity is applied).

Remarks

The size of the destination image corresponds to the reference size.
dAlphaBlend blends the images and keeps the alpha channel of the destination image. Therefore, the alpha channel of the source image is not used.
