Input
|
|
An integer between 0 and 116 specifying the input image frame number. A value of 0 represents the DMA memory buffer of the video device. Values in the range of 100-116 correspond to hidden frames.
|
|
Output
|
|
An integer between 1 and 116 specifying the output image frame number. Values in the range of 100-116 correspond to hidden frames.

|
Probe
|
|
An enumerated integer that describes the shape and size of the kernel used in the operation. The value is determined as a combination of four basic shapes constructed of 3 pixels:
|
|
PR_VBAR=1 vertical bar
|
PR_BKSLASH=2 diagonal bar (top left bottom right)
|
PR_HBAR=4 horizontal bar
|
PR_FWSLASH=8 diagonal bar (bottom left top right)
|
|
The following frequently used shapes represent combinations of the basic shapes:
|
|
PR_CROSS=5 cross 3x3
|
PR_DCROSS=10 diagonal cross 3x3
|
PR_SQUARE=15 square 3x3
|
|
You can also assign one kernel of size 5x5:
|
|
PR_CIRCLE=16 circle 5x5
|
|
ERR_OK
|
|
The flag set if successful.
|
ERR_FAILED
|
|
The flag set if failed.
