The Point annotation object (ANNOBJECT_POINT) is single point. With the automated functions, in design mode, each point is formed with a mouse click event.
The class for Point Annotation objects is LAnnPoint.
For information on flipping, reversing or rotating annotation objects, refer to Flipping, Reversing and Rotating Annotation Objects.
With low-level functions, you must define the point by calling LAnnPoint::SetPoints. Other applicable properties have the following defaults, which you can change:
Visible |
Defaults to FALSE. It can be changed using the LAnnotation::SetVisible function. |
Selected |
Defaults to FALSE. It can be changed using the LAnnotation::SetSelected function. |
Name |
Defaults to an empty string. It can be changed using the LAnnotation::SetNameOptions function. |
Line width |
Defaults to 0.75 points. It can be changed using the LAnnXXX::SetLineWidth function. (Note that when displayed, the line must have a minimum width of 1 pixel.) |
Line style |
Defaults to solid. It can be changed using the LAnnXXX::SetLineStyle function. |
ROP2 code |
Defaults to ANNROP2_COPY. It can be changed using the LAnnotation::SetROP2 function. |
Transparent option |
Defaults to Use Transparent Color. It can be changed using the LAnnPoint::SetTransparent function. |
Transparent Color |
Defaults to White. It can be changed using the LAnnPoint::SetTransparentColor function. |
Bitmap |
Defaults to NULL. It can be changed using the LAnnXXX::SetBitmap function. |
Point |
Defaults to a bitmap of a cross inside a circle. It can be changed using the LAnnPoint::SetPredefinedBitmap function. |
Fixed State |
Defaults to not fixed. It can be changed using the LAnnXXX::SetFixed function. |
Hyperlink |
Defaults to ANNLINK_NONE. It can be changed using the LAnnotation::SetHyperlink function. |
Tag (identifier) |
Defaults to 0. It can be changed using the LAnnotation::SetTag function. |
Window handle |
Defaults to NULL or the handle inherited from the container. It can be changed for all objects using LAnnContainer::SetWnd. |
User mode |
Defaults to design mode or the mode inherited from the container. It can be changed for all objects using LAnnContainer::SetUserMode. |
