Function Documentation

MV_CC_DisplayOneFrameEx()

MV_CAMCTRL_API int __stdcall MV_CC_DisplayOneFrameEx	(	IN void *	handle,
		IN void *	hWnd,
		IN MV_DISPLAY_FRAME_INFO_EX *	pstDisplayInfo
	)

Display one frame of image (extended API 1).

Parameters

handle	[IN] Device handle.
hWnd	[IN] Window handle.
pstDisplayInfo	[IN] Image information.

Returns

Return MV_OK for success, and return corresponding error code for failure.

Note

 •  The rendering mode can be set to GDI (default) or D3D. Once it is switched from GDI to D3D, it cannot be switched back to GDI.

• The GDI mode GDI is applicable to all computers with no requirements on graphic card performance.
• The D3D mode is applicable to computers with installed graphic card of memory larger than 1 GB. In this mode, the live view image on the client will be better than the one in GDI mode.
• It supports rendering images in pixel format including PixelType_Gvsp_RGB8_Packed, PixelType_Gvsp_BGR8_Packed, and PixelType_Gvsp_Mono8, and with integer type width and height, and supports rendering images in other pixel format with short type width and height.

MV_CC_DisplayOneFrameEx2()

MV_CAMCTRL_API int __stdcall MV_CC_DisplayOneFrameEx2	(	IN void *	handle,
		IN void *	hWnd,
		IN MV_CC_IMAGE *	pstImage,
		unsigned int	enRenderMode
	)

Display one frame of image (extended API 2).

Parameters

handle	[IN] Device handle.
hWnd	[IN] Window handle.
pstImage	[IN] Image information.
enRenderMode	[IN] Image rendering mode: 0: OpenGL.

Returns

Return MV_OK for success, and return corresponding error code for failure.

Note

 • Supported rendering an image over 4 GB in PixelType_Gvsp_RGB8_Packed, PixelType_Gvsp_BGR8_Packed, and PixelType_Gvsp_Mono8 formats.
 • For an image below 4 GB, the image width and image height supports rendering to integer type.
 • To use this API, you should enter the value of nImageLen in structure MV_CC_IMAGE .
