imagekitcontrolname.SetTransBlue(short Val)
Reference
TransBlue The transparent color's blue value.
Values range from 0 to 255
Explanation
The TransRed, TransGreen, and TransBlue
properties are used to set a transparent color in the base (raster)
image. The ImageKit Control background will be seen in the areas of
the image that are set to transparent. To set a transparent
color in an image, the image must be either 8 bit color or 24 bit
color. If a vector image is set in the base image, these properties
are disabled.
To set a transparent color in an image layer, please refer to the
Layer.TransRed, Layer.TransGreen, and Layer.TransBlue properties.
Example: Setting the transparent color to white
ImageKit1.TransBlue = 255
ImageKit1.TransGreen = 255
ImageKit1.TransRed = 255
ImageKit1.Transparent = True
ImageKit1.LayerNo = -1
ImageKit1.File.LoadFile(ikLoad)
