Add Rectangle to PS

In order to add a rectangle to PsDocument with Aspose.Page for Java library we should do the following steps:

1. Create an output stream for the resulting PS file.
2. Create PsSaveOptions object with default options.
3. Create a 1-paged PsDocument with an already created output stream and save options.
4. Create a rectangle (java.awt.geom.Rectangle2D object).
5. Set a paint to the current graphics state of PsDocument.
6. Fill the rectangle.
7. Close the page.
8. Save the document.

If we need to stroke (outline) a rectangle the first 4 and the last 2 steps will be the same, but points 5 and 6 will be:

5. Set the stroke to the current graphics state of PsDocument.
   
6. Stroke (outline) the rectangle.

//Create output stream for PostScript document
FileOutputStream outPsStream = new FileOutputStream(dataDir + "AddRectangle_outPS.ps");
//Create save options with A4 size
PsSaveOptions options = new PsSaveOptions();

// Create new PS Document with the page opened
PsDocument document = new PsDocument(outPsStream, options, false);

//Set paint for filling rectangle
document.setPaint(Color.ORANGE);        
//Fill the first rectangle
document.fill(new Rectangle2D.Float(250, 100, 150, 100));

//Set paint for stroking rectangle
document.setPaint(Color.RED);
//Set stroke
document.setStroke(new BasicStroke(3));
//Stroke (outline) the second rectangle
document.draw(new Rectangle2D.Float(250, 300, 150, 100));

//Close current page
document.closePage();
//Save the document
document.save();

Add Ellipse to PS

In order to add ellipse to PsDocument also 8 steps are required:

1. Create an output stream for the resulting PS file.
2. Create PsSaveOptions object with default options.
3. Create a 1-paged PsDocument with an already created output stream and save options.
4. Create an ellipse (java.awt.geom.Ellipse2D object).
5. Set paint to the current graphics state of PsDocument.
6. Fill the ellipse path.
7. Close the page.
8. Save the document.

If we need to stroke (outline) an ellipse the first 4 and the last 2 steps will be the same but points 5 and 6 will be:

5. Set stroke to the current graphics state of PsDocument.
6. Stroke (outline) the ellipse:

//Create output stream for PostScript document
FileOutputStream outPsStream = new FileOutputStream(dataDir + "AddEllipse_outPS.ps");
//Create save options with A4 size
PsSaveOptions options = new PsSaveOptions();

// Create new multipaged PS Document with one page opened
PsDocument document = new PsDocument(outPsStream, options, false);

//Set paint for filling rectangle
document.setPaint(Color.ORANGE);        
//Fill the first ellipse
document.fill(new Ellipse2D.Float(250, 100, 150, 100));

//Set paint for stroking rectangle
document.setPaint(Color.RED);
//Set stroke
document.setStroke(new BasicStroke(3));
//Stroke (outline) the second ellipse
document.draw(new Ellipse2D.Float(250, 300, 150, 100));

//Close current page
document.closePage();
//Save the document
document.save();

As we can see, any shape, both closed and unclosed, can be filled or drawn by PsDocument. It also can be clipped, but it will be described in another article.
