Python GafferImage.Dilate Examples

Example #1

File: DilateTest.py Project: whitemoonstone/gaffer

	def testFilter( self ) :

		r = GafferImage.ImageReader()
		r["fileName"].setValue( os.path.dirname( __file__ ) + "/images/radial.exr" )

		m = GafferImage.Dilate()
		m["in"].setInput( r["out"] )
		self.assertImagesEqual( m["out"], r["out"] )

		m["radius"].setValue( imath.V2i( 12 ) )
		m["boundingMode"].setValue( GafferImage.Sampler.BoundingMode.Clamp )

		dataWindow = m["out"]["dataWindow"].getValue()
		s = GafferImage.Sampler( m["out"], "R", dataWindow )

		self.assertEqual( s.sample( 112, 112 ), 1.0 )

Example #2

File: DilateTest.py Project: wubugui/gaffer

    def testExpandDataWindow(self):

        c = GafferImage.Constant()

        m = GafferImage.Dilate()
        m["in"].setInput(c["out"])
        m["radius"].setValue(imath.V2i(1))

        self.assertEqual(m["out"]["dataWindow"].getValue(),
                         c["out"]["dataWindow"].getValue())

        m["expandDataWindow"].setValue(True)

        self.assertEqual(
            m["out"]["dataWindow"].getValue().min(),
            c["out"]["dataWindow"].getValue().min() - imath.V2i(1))
        self.assertEqual(
            m["out"]["dataWindow"].getValue().max(),
            c["out"]["dataWindow"].getValue().max() + imath.V2i(1))
