Draw Graphics in Java Programmatically - Code Snippet

Let’s dive into how to draw graphics in Java using Aspose.PSD for Java.

Follow the steps below:

  1. Create an instance of Image class.
  2. Initialize an object of the Graphics class.
  3. Clear the image surface with white color by calling the clear method.
  4. Initialize a Pen object with blue color.
  5. The drawEllipse method will draw Ellipse by defining the bounding rectangle of width 150 and height 100.
  6. Draw a polygon using the LinearGradientBrush class.
  7. The fillPolygon method will fill the interior of a polygon.
  8. The save method will save the drawing as a BMP image on the disk.

The following code sample shows how to draw graphics in Java programmatically:

public class main {
public static void main(String[] args) throws java.io.IOException {
String dataDir = "/files/";
// Create an instance of Image class.
PsdImage image = new PsdImage(500, 500);
// Initialize an object of the Graphics class.
Graphics graphics = new Graphics(image);
// Clear the image surface with white color by calling the clear method.
graphics.clear(Color.getWhite());
// Initialize a Pen object with blue color.
Pen pen = new Pen(Color.getBlue());
// The drawEllipse method will draw Ellipse by defining the bounding rectangle of width 150 and height 100.
graphics.drawEllipse(pen, new RectangleF(10, 10, 150, 100));
// Draw a polygon using the LinearGradientBrush class.
LinearGradientBrush linearGradientBrush = new LinearGradientBrush(image.getBounds(), Color.getRed(), Color.getWhite(), 45f);
Point[] points = { new Point(200, 200), new Point(400, 200), new Point(250, 350) };
// The fillPolygon method will fill the interior of a polygon.
graphics.fillPolygon(linearGradientBrush, points);
// The save method will save the drawing as a BMP image on the disk.
image.save(dataDir+ "DrawingUsingGraphics.bmp", new BmpOptions());
}
