Freehand Line Annotation Object - Raster imaging C++ Class Library Help

Freehand Line Annotation Object

The freehand annotation object (ANNOBJECT_FREEHAND) is an array of points that create a sequence of joined lines. With the automated functions, each line segment is formed with a mouse move event when the left button is down, and the object is completed on a mouse up event.

The class for Freehand Line Annotation objects is LAnnFreehand.

For information on flipping, reversing or rotating annotation objects, refer to Flipping, Reversing and Rotating Annotation Objects.

With low-level functions, you must provide the points that define the shape of the object. 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.

Foreground color

Defaults to red. It can be changed using the LAnnXXX::SetForeColor function.

Nodes

Defaults to displaying every node. It can be changed using the LAnnXXX::SetNodes 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.

User mode

Defaults to design mode or the mode inherited from the container.
