Directory Structure;FilenameFunction(s)Canvas.phpThis is the collection, it contains the list of objects.MainDriver.phpThis runs the project. It simply displays a graphic of a house at the end. (See appendix).shape_input_file.xmlXML defining all the shapes.shape_input_file_TEST.xmlXML for testing the “TestGraphics” file. See appendix.ShapeFactory.phpGenerates the shapes as we read the XML file.Write a simple factory to return the shapes you need.ShapeIterator.phpProvides an interator to process the collection in Canvas.You can re-use the method shown in class (Iterator for books).TestDriverThe tests (See appendix)TestGraphicsThe graphic tests (See appendix)Method structure;Canvas.phpMethod NameDetailsConstructorThis contains most of the code for this assignment!1)Define an object of the factory, to get shapes.2)Read the XML file for the background color, sizes, and issue a “imagefill” command to take care of it. Reminder, to get the color use the allocatecolor method like this: $this->allocateColor($back_color).3)When creating the image here, using imagecreatetruecolor, remember that the values for width and height might need to be casted to integer for it to work. Eg: $this->im = imagecreatetruecolor((int)$back_width, (int)$back_height);4)Do a foreach on all the shapes in the XML, for each shape get the shape from the factory, fill in the values,and then add it to the canvas using the “addShape” method.Note: When reading in the XML, example, the children() of shapes, you can get the name of the current elements Page 2 of 16
