I don't have a problem doing #1, but I am having trouble actually coding these classes in Java so it can be converted to svg.

For the SvgMaker class this is what I have so far. I don't know if it's correct.

import java.io.File;

import java.io.FileNotFoundException;

import java.io.PrintWriter;

public class SvgMaker

{

public int imWidth;

public int imHeight;

public String fileName;

private PrintWriter fp;

public void setFp(PrintWriter fp_in)

{

fp = fp_in;

}

public PrintWriter getFp()

{

return fp;

}

public SvgMaker(int imWidth_in, int imHeight_in, String fileName_in)

{

// Capture incoming member variables

imWidth = imWidth_in;

imHeight = imHeight_in;

fileName = fileName_in;

// Open File

fileName = "C:/Users/mvanc/OneDrive/Documents/svg.txt";

PrintWriter outFile = null;

// Write opening svg tag to the file

try

{

outFile = new PrintWriter(new File(fileName));

outFile.print("

outFile.print(" xmlns = 'http://www.w3.org/2000/svg' ");

outFile.print(" xmlns:xlink = 'http://www.w3.org/1999/xlink' ");

outFile.print(" version = '1.1' ");

outFile.print(" width = " + "'" + imWidth + "'" + "height = " + "'" + imHeight + "'> ");

}

catch(FileNotFoundException ex)

{

System.out.print(" Error opening file: " + fileName);

}

}

public void drawCircle(Circle c, Fill fc, Stroke sc)

{

}

public void drawRectangle(Rectangle r, Fill fr, Stroke sr)

{

}

public void drawRoundedRectangle(RoundedRectangle rr, Fill frr, Stroke srr)

{

}

public void drawLine(Line l, Stroke sl)

{

}

public void drawPath(Path p, Fill fp, Stroke sp)

{

}

public void close()

{

// Write closing svg tag to file

fileName = "C:/Users/mvanc/OneDrive/Documents/svg.txt";

PrintWriter outFile = null;

try

{

outFile = new PrintWriter(new File(fileName));

outFile.print(" />");

outFile.print("");

}

catch(FileNotFoundException ex)

{

System.out.print(" Error opening file: " + fileName);

}

// Close file

outFile.flush();

outFile.close();

}

}

Circle class:

import java.io.File;

import java.io.PrintWriter;

public class Circle

{

int cx;

int cy;

int r;

public Circle(int cx_in, int cy_in, int r_in)

{

cx = cx_in;

cy = cy_in;

r = r_in;

PrintWriter outFile = null;

outFile.print("

outFile.print(" r = " + "'" + r + "' ");

}

}

Dashed Stroke Class:

import java.io.PrintWriter;

public class DashedStroke extends Stroke // Child class of Stroke

{

int d1; // First dash

int d2; // Second dash

public DashedStroke(String s_in, int sw_in, int d1, int d2)

{

// Call parent constructor

super (s_in, sw_in);

this.d1 = d1;

this.d2 = d2;

PrintWriter outFile = null;

outFile.print(" stroke = '" + s + "' stroke-width = '" + sw + "' ");

outFile.print(" stroke-dasharray = '" + d1 + "," + d2 + "' ");

}

}

Fill Class:

import java.io.PrintWriter;

public class Fill // rgb function

{

int r; // Red

int g; // Green

int b; // Blue

public Fill(int r_in, int g_in, int b_in)

{

r = r_in;

g = g_in;

b = b_in;

PrintWriter outFile = null;

outFile.print(" fill = 'rgb(" + r + "," + g + "," + b + ")' ");

}

}

Line Class:

import java.io.PrintWriter;

public class Line

{

int x1;

int y1;

int x2;

int y2;

public Line(int x1_in, int y1_in, int x2_in, int y2_in)

{

x1 = x1_in;

y1 = y1_in;

x2 = x2_in;

y2 = y2_in;

PrintWriter outFile = null;

outFile.print("

outFile.print(" x2 = '" + x2 + "' y2 = '" + y2 + "' ");

}

}

Path Class:

import java.io.PrintWriter;

public class Path

{

int x1;

int y1;

int x2;

int y2;

int x3;

int y3;

public Path(int x1_in, int y1_in, int x2_in, int y2_in, int x3_in, int y3_in)

{

x1 = x1_in;

y1 = y1_in;

x2 = x2_in;

y2 = y2_in;

x3 = x3_in;

y3 = y3_in;

PrintWriter outFile = null;

outFile.print("

}

Rectangle Class:

import java.io.PrintWriter;

public class Rectangle // Parent Class to RoundedRectangle

{

int x;

int y;

int width;

int height;

public Rectangle(int x_in, int y_in, int width_in, int height_in)

{

x = x_in;

y = y_in;

width = width_in;

height = height_in;

PrintWriter outFile = null;

outFile.print("

outFile.print(" width = '" + width + "' height = '"+ height + "' ");

}

}

RoundedRectangle Class:

import java.io.PrintWriter;

public class RoundedRectangle extends Rectangle // Child Class of Rectangle

{

int r;

public RoundedRectangle(int x_in, int y_in, int width_in, int height_in, int r)

{

// Call parent constructor

super (x_in, y_in, width_in, height_in);

this.r = r;

PrintWriter outFile = null;

outFile.print("

outFile.print(" width = '" + width + "' height = '"+ height + "' ");

outFile.print(" r = '" + r + "' ");

}

}

Stroke Class:

import java.io.PrintWriter;

public class Stroke // Parent Class to DashedStroke

{

String s; // Stroke

int sw; // Stroke-width

public Stroke(String s_in, int sw_in)

{

s = s_in;

sw = sw_in;

PrintWriter outFile = null;

outFile.print(" stroke = '" + s + "' stroke-width = '" + sw + "' ");

}

}

Test Class:

public class TestClass

{

public static void main(String[] args)

{

SvgMaker svg = new SvgMaker(300, 300, "C:/Users/mvanc/OneDrive/Documents/svg.txt");

Circle c = new Circle(2, 1, 6);

Fill fc = new Fill(0,0, 255);

Stroke sc = new Stroke("black", 3);

Rectangle r = new Rectangle(10, 20, 5, 5);

Fill fr = new Fill(255, 0, 0);

Stroke sr = new Stroke("blue", 2);

RoundedRectangle rr = new RoundedRectangle(10, 20, 5, 5, 2);

Fill frr = new Fill(255, 0, 255);

Stroke srr = new Stroke("red", 7);

Line l = new Line(3, 6, 5, 10);

Stroke sl = new Stroke("blue", 2);

Path p = new Path(50, 50, 250, 50, 100, 200);

Fill fp = new Fill(255, 255, 255);

Stroke sp = new Stroke("black", 1);

}

}

1. Create a UML diagram for the following classes: Fill Stroke Line Circle Rectangle SvgMaker The svgMaker class has a member variable of the file pointer (a iter object), the image width, the image height, and all the drawing methods, such as drawLine, etc. 2. Create the following child classes: Rounded Rectangle Dashed stroke 3. Code the classes in Java and create a Testclass to test out your code. 4. (a) Use your classes to create the algorithmic image shown below (b) Modify the algorithm in some interesting way or else create your own interesting algorithm and create another image
