imagekitcontrolname.SetTransRed(short Val)
Reference
TransRed The transparent color's red 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)
