BB FlashBack SDK: FBWatermarkProperties

AlphaMode

Description

Returns or sets a value that determines whether alpha channel information encoded into the watermark image is used.

Syntax

[C#/C++]
public long AlphaMode

[VB.NET]
Public Property AlphaMode As Long

Remarks

Possible values:

0

No alpha channel detected in bitmap

1

Image contains alpha channel and it is being used.

2

Image contains alpha channel, but it is not used in display.

Setting the value to zero has the same effect as setting it to 2 - any alpha channel information present is ignored.

Setting the value to one only has an effect if the image contains an alpha channel. Of the image formats supported by the SDK, alpha channels are only supported for 24 bit PNG files.
