Detailed Description

Blurs the source image

Filter Parameters:

   Name                                |   Type   | Opt/Reqd |  Range
   ==========================================================================
   FE2_BLUR_FILTER                     | Numeric  | Optional | blurfilter_t
   FE2_BLUR_MASKSIZE                   | Numeric  | Optional | masksiz_t

Example Usage:

   sc = Flix2_AddFilter(&filter, flix, FE2_FILTER_BLUR);

   //blur the image using a Gaussian kernel
   if(sc == ON2_OK)
       sc = Flix2_FilterSetParam(&filter, FE2_BLUR_FILTER, BLUR_GAUSS);

Define Documentation

#define FE2_BLUR_FILTER

Specifies blur filter to be applied to source.

The blur filter may be selected from blurfilter_t.

Note:

Default: BLUR_LOWPASS

#define FE2_BLUR_MASKSIZE

Specifies the kernel/mask size to be used.

The mask size may be selected from masksiz_t.

Note:

Default: MASK_3x3
