Remarks
(Document/Medical only) (Persistent property, available at design time) Enables or disables double buffered image display in the control. Use this to avoid flicker when the control repaints invalidated areas. Possible values are:
|
Value |
Meaning |
|
TRUE |
Enable double buffering |
|
FALSE |
Disable double buffering |
This is especially useful when displaying annotations on the image. Without enabling double buffered painting, the image is painted first, and then the annotations are rendered. This can cause flicker, and, it allows the portion under the annotation objects, for example a Redact object, to be visible.
