Crossproduct Annotation Object
The CrossProduct annotation object (ANNOBJECT_CROSSPRODUCT) consists of two rulers intersecting at right angles. With the automated functions, the CrossProduct is started on a mouse-down event and completed on a mouse-up event.
The class for CrossProduct Annotation objects is LAnnCrossProduct.
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 points by calling the LAnnRuler::SetPoints function. The points are ordered as follows:
Other applicable properties have the following defaults, which you can change:
| Property | Defaults |

| 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 LAnnRuler::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 LAnnRuler::SetLineStyle function. |
| ROP2 code | Defaults to ANNROP2_COPY. It can be changed using the LAnnotation::SetROP2 function. |
| Fill mode | Defaults to transparent. It can be changed using the LAnnotation::SetFillMode function. |
| Foreground color | Defaults to red. It can be changed using the LAnnotation::SetForeColor function. |
| Background color | Defaults to white. It can be changed using the LAnnotation::SetBackColor function. |
