AnnSetROP2 method (Annotation Control)
|
Builder Syntax |
int AnnSetROP2(HANNOBJECT hObject, unsigned uROP2, bool bSelected) |
|
Delphi Syntax |
Function AnnSetROP2(hObject: HANNOBJECT; uROP2: L_UINT; bSelected: Boolean): L_INT |
|
Overview |
Refer to Implementing Annotations. |
Remarks
(Document/Medical only) Sets the ROP2 code for one or more annotation objects. ROP2 codes specify how pen or brush colors are to be combined with the colors in the image.
It is possible to use the AnnSetROP2 method to turn a simple rectangle into a hilite-type object. This is the only way to have a hilite object that has different colors for border and interior. To do that, draw a rectangle with a thick border, choose different foreground and background colors (using the AnnSetForeColor method and the AnnSetBackColor method), and then call this method with uROP2 set to ANNROP2_AND.
The AnnSetROP2 method is valid only for the following object types:
In addition, the Automation object (ANNOBJECT_AUTOMATION) stores ROP2 settings along with the other object default settings
For descriptions of the various types of objects and their properties, refer to Types of Annotations.
Note that the AnnSetROP2 method and the AnnSetFillMode method affect each other. If you set nFillMode to ANNFILLMODE_OPAQUE, then nROP2 cannot be ANNROP2_AND. If you set nFillMode to ANNFILLMODE_TRANSLUCENT, then nROP2 has to be ANNROP2_AND. If you set nFillMode to ANNFILLMODE_TRANSPARENT, nROP2 can be anything.
Use the AnnGetROP2 method to obtain the ROP2 code being used for one or more annotation objects.
When working with automated annotations, note that it is possible to change the color of the pen that is used for highlighting and selecting by setting the AnnAutoHilightPen property for that automation object.
