gauss



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 100116 correspond to hidden frames.


Output


An integer between 1 and 116 specifying the output image frame number. Values in the range of 100116 correspond to hidden frames.


Size


An odd integer between 1 and 2*Overscan+1 specifying the size of the Gaussian kernel. This value determines the standard deviation (sigma) of the Gaussian distribution, so that the kernel is effectively truncated at the point of three sigma.. The Overscan setting is defined in ImageWarp Preferences.


ERR_OK


The flag set if successful.


ERR_FAILED


The flag set if failed.

This statement performs the lowpass filtration of the image 1 using the window of size 7:


gauss (1, 1, 7)
