iluBlurGaussian

The iluBlurGaussian function blurs an image.

 

ILboolean iluBlurGaussian(
  ILuint Iter
);

Parameters

Iter
Number of iterations of blurring to perform.

Remarks

iluBlurGaussian blurs an image using a Gaussian convolution filter, which usually gives better results than the filter used by iluBlurAvg. The filter is applied up to Iter number of times, giving more of a blurring effect the higher Iter is. The 3x3 convolution filter used to do the average blur is:

1, 2, 1,

2, 4, 2,

1, 2, 1,

   16

Error Codes
