void DrawChars(
HDC graphicContext,
const ERGBColor& color,
float zoomX,

)
Parameters
graphicContext
Handle of the device context on which to draw.
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 overlay.
Remarks
Drawing is done in the device context associated to the desired window. The current pen is used for all characters (to vary the colors, draw the objects separately using the EOCR::DrawChar method instead).
EOCR.DrawChars
