USB 2.0
-
Syntax
INT is_LockDDMem (HIDS hCam, void** ppMem, INT* pPitch)
Description
Attention
This function is obsolete and should not be used anymore. We recommend to use the is_DirectRenderer()
function instead (see also Obsolete functions ).
is_LockDDMem() enables access to the image memory in DirectDraw mode and returns the pointer to the image
memory. In most cases, the image memory is located on the graphics card. Using the pointer, you have direct
access to the image memory. Make sure to release the memory as early as possible using the is_UnlockDDMem
() function.
Calling is_LockDDMem() will not interrupt the process of digitizing an image and saving it to the memory area.
While a LockDDMem … UnlockDDMem block is executed in DirectDraw BackBuffer mode, the contents of the back
buffer will not be refreshed on the screen.
