Examples with Parameters org.apache.sis.parameter.Parameters used on opensource projects

Example 1 with Parameters

use of org.apache.sis.parameter.Parameters in project sis by apache.

the class EquirectangularTest method createCompleteProjection.

/**
 * Initializes a simple Equirectangular projection on sphere. This method is different than the
 * {@code createNormalizedProjection(boolean)} method in all other test classes, because it does
 * not create an instance of {@link NormalizedProjection}. Instead, it creates an affine transform
 * for the whole projection (not only the normalized part).

Example 2 with Parameters

use of org.apache.sis.parameter.Parameters in project sis by apache.

the class MapProjectionTestCase method parameters.
