LVectorDialog::DoModalVectorScale

Summary

Brings up the Vector Scale dialog.

Syntax

virtual L_INT LVectorDialog::DoModalVectorScale(hWndParent=NULL, pScale=NULL, pOrigin=NULL)

Parameters

HWND hWndParent

Handle of the window that owns the dialog.

pVECTORPOINT pScale

Pointer to a VECTORPOINT structure that contains scale values. The values present in pScale when the function is called are used to initialize the dialog. If this parameter is NULL when the function is called, the values used to initialize the dialog will come from the vector handle. When this function returns, this parameter is updated with the values entered through the dialog.

const pVECTORPOINT pOrigin

Pointer to a VECTORPOINT structure that contains the origin of the scale. (The point about which the scaling occurs.) If pOrigin is not NULL, scaling occurs around this point. If pOrigin is NULL, the center of scaling is the accumulative center of the objects to be scaled.

Returns

Comments

If no objects are currently selected in the source vector handle, all of the objects in the vector handle will be scaled in the dialog.

If there are selected objects inside the source vector handle, only those objects will be scaled in the dialog.
