DoGFilter

public DoGFilter()

Method Detail

setRadius1

public void setRadius1(float radius1)

Set the radius of the kernel, and hence the amount of blur. The bigger the radius, the longer this filter will take.

Parameters:

radius1 - the radius of the blur in pixels, min-value 0, max-value 100+

See Also:

getRadius1()

getRadius1

public float getRadius1()

Get the radius of the kernel.

Returns:

the radius

See Also:

setRadius1(float)

setRadius2

public void setRadius2(float radius2)

Set the radius of the kernel, and hence the amount of blur. The bigger the radius, the longer this filter will take.

Parameters:

radius2 - the radius of the blur in pixels, min-value 0, max-value 100+.

See Also:

getRadius2()

getRadius2

public float getRadius2()

Get the radius of the kernel.

Returns:

the radius
