GMapRect Class Reference

#include <GMapAreas.h>

Inheritance diagram for GMapRect:

GMapArea GPEnabled

List of all members.

Detailed Description

Implements rectangular map areas. This is the only kind of map areas supporting SHADOW_IN_BORDER#, SHADOW_OUT_BORDER#, SHADOW_EIN_BORDER# and SHADOW_EOUT_BORDER# types of border and area highlighting.

Definition at line 292 of file GMapAreas.h.


Files #"GMapAreas.h"# and #"GMapAreas.cpp"# implement base objects used by the plugin to display and manage hyperlinks and highlighted areas inside a {DjVuImage} page.

The currently supported areas can be rectangular ({GMapRect}), elliptical ({GMapOval}) and polygonal ({GMapPoly}). Every map area besides the definition of its shape contains information about display style and optional { URL}, which it may refer to. If this { URL} is not empty then the map area will work like a hyperlink.

The classes also implement some useful functions to ease geometry manipulations
