Syntax
INT is_GetDC (HIDS hCam, HDC* phDC)
Description
This function is obsolete and should not be used anymore. We recommend to use the
is_DirectRenderer() function instead (see also Obsolete Functions ).
In DirectDraw BackBuffer mode, is_GetDC() returns the device context handle of the overlay buffer.
Using this handle, it is possible to access the overlay using the Windows GDI functionality. Thus, all
Windows graphics commands such as Line, Circle, Rectangle, TextOut,... are available. You
should release the device context handle as early as possible using the is_ReleaseDC()
function. While a GetDC...ReleaseDC block is executed, the overlay buffer on the screen will not be
updated.
Input Parameters
hCam
Camera handle
phDC
Pointer to the variable that is supposed to contain the device context handle
Return Values
IS_SUCCESS
Function executed successfully
IS_NO_SUCCESS
