   float panX,
   float panY
)

Parameters

drawAdapter

zoomX

Horizontal zooming factor. By default, true scale is used.

zoomY

Vertical zooming factor. If set to 0 (default), the horizontal zooming factor is used instead, so as to provide isotropic zooming.

panX

Horizontal panning value expressed in pixels. By default, no panning occurs.

panY

Vertical panning value expressed in pixels. By default, no panning occurs.

color

The color in which to draw the region.

hdc

Handle of the device context on which to draw.

Remarks

Deprecation notice: All methods taking HDC as parameter are deprecated. It is recommended to use their alternative taking a EDrawAdapter by using a instance of EWindowsDrawAdapter.
