virtual L_INT LAnnotation::Resize(dFactorX, dFactorY, pCenter, uFlags=0)
Changes the size of the annotation object, letting you specify the point that is to remain stationary.
Factor by which to change the width of the object, used as follows:
New width = Old width * dFactorX
Factor by which to change the height of the object, used as follows:
New height = Old height * dFactorY
Pointer to an ANNPOINT structure that specifies the point that is to remain stationary.
You can pass NULL to use the default, which is the center of the object. If more than one object is selected, each object is resized on its own center.
The ANNPOINT structure is like a Windows POINT structure, except that it uses double-precision floating point values.
Coordinates of the point are relative to its container object. The coordinates are interpreted using the container's scaling factors and offsets, which are described in Low-Level Coordinate System for Annotations.
Flags that determine which objects to process. Most of the flags apply only to container objects. You can combine values when appropriate by using a bitwise OR (|). The following are valid values:
|0||Process only the specified object.|
|ANNFLAG_SELECTED||[0x0001] Process only objects that have the selected property set to TRUE. For getting and setting the selected property, use the LAnnContainer::GetSelectItems and LAnnotation::SetSelected functions.|
|ANNFLAG_NOTTHIS||[0x0004] Process only one level of objects within the specified container, not the container itself. If there are containers within the container, they are modified, but the objects within them are not.|
|ANNFLAG_RECURSE||[0x0008] Process objects within a container, and within any subcontainers, down to any level.|
|ANNFLAG_NOTCONTAINER||[0x0002] (Used with ANNFLAG_RECURSE) Process objects within containers, not the containers themselves.|
|ANNFLAG_NOINVALIDATE||[0x0010] Do not invalidate the affected rectangle in the window. Use this to avoid generating unwanted paint messages.|
|SUCCESS||The function was successful.|
|< 1||An error occurred. Refer to Return Codes.|
This function uses unscaled values that are relative to the container object. For more information, refer to Low-Level Coordinate System for Annotations.
This function applies to multiple and selected objects based on values of the uFlags parameter.
For an example, refer to LAnnotation::CutToClipboard.
