Python nb_data_bands Exemples

Exemple #1

    def test_alpha_mask(self):
        SOME_RANDOM_NUMBER = 42
        self.ds.RasterCount = SOME_RANDOM_NUMBER
        self.ds.GetRasterBand(1).GetMaskBand().GetMaskFlags.return_value = gdal.GMF_ALPHA

        # Should consider there is an alpha band
        self.assertEqual(gdal2tiles.nb_data_bands(self.ds), SOME_RANDOM_NUMBER - 1)

Exemple #2

    def test_2_bands_means_gray_alpha(self):
        self.ds.RasterCount = 2

        self.assertEqual(gdal2tiles.nb_data_bands(self.ds), 1)

Exemple #3

    def test_4_bands_means_rgba(self):
        self.ds.RasterCount = 4

        self.assertEqual(gdal2tiles.nb_data_bands(self.ds), 3)

Exemple #4

    def test_1_band_means_gray(self):
        self.ds.RasterCount = 1

        self.assertEqual(gdal2tiles.nb_data_bands(self.ds), 1)
