Syntax

<Image control>.AlphaBlend(<Source image> [, <Opacity>])

<Image control>: Control name

Name of the Image control that corresponds to the image in which the blend will be performed. 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.
the name of a variable of type WDPic. Only the background layer will be handled.
the name of a variable of type picLayer.

<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.
<Image>.AlphaBlend blends the images and keeps the alpha channel of the destination image. Therefore, the alpha channel of the source image is not used.
