Control buffer features.
void MbufControl(BufId, ControlType, ControlValue)
|MIL_ID BufId;||Buffer identifier|
|long ControlType;||Type of buffer feature to control|
|double ControlValue;||Value associated with control type|
This function allows you to control certain buffer features.
The BufId parameter specifies the identifier of the buffer.
The ControlType and ControlValue parameters specify the buffer feature to control and the value needed for the control. These two parameters should be set to one of the following:
|M_ASSOCIATED_LUT||LUT buffer identifier||Associate a LUT buffer with the specified image buffer.|
|M_MODIFIED||M_DEFAULT||Signal MIL that the buffer content was modified without using MIL. This control must be used to ensure that MIL updates its internal information on the buffer. Note, if only a certain region of the buffer was modified, specify an appropriate child buffer as BufId.|
|M_WINDOW_DC_ALLOC||M_DEFAULT||Allocate a Windows display context (DC) for drawing. Determine the DC handle (HDC) using MbufInquire|
|M_WINDOW_DC_FREE||M_DEFAULT||Free a Windows display DC.|
|* Note: The display context must be allocated and used only for very short periods of time. Free it as soon as possible.|
The ControlType M_ASSOCIATED_LUT is not available with 32-bit or floating-point buffers.
