public abstract class TestBase
extends Object

This class is an abstract class used for creating test images used by the affine and scale operation test-classes. The only two methods defined are roiCreation() and createTestImage(). The first is used for creating a new ROI object with height and width respectively half of the image height and width. The second is used for creating a test image of the selected data type. The image can be filled with data inside by setting the ImageN.Ext.ImageFill parameter to true from the console, but this slows the test-computations. The image is by default a cross surrounded by lots of pixel with value 0. For binary images a big rectangle is added into the left half of the image; for not-binary images a simple square is added in the upper left of the image. The square is useful for the rotate operation(inside the jt-affine project) because it shows if the image has been correctly rotated.
