Illustration of Fill Options for Annotations
Previous versions of LEADTOOLS supported annotations with translucent backgrounds. An alpha option allows you to specify an alpha value from 0 (completely transparent background) to 255 (completely opaque background) inclusive.
When enabled using the LAnnotation::SetOptions function, you can right-click an annotation object to display the Fill dialog with the new alpha option. Here you can enter an alpha value from 0 to 255 inclusive. This figure displays the Fill dialog for the Stamp object.
