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.

// Add Rectangle to PS document.

String outputFileName = "AddRectangle_outPS.ps";

//Create save options with A4 size
PsSaveOptions options = new PsSaveOptions();

// Create new 1-paged PS Document
PsDocument document = new PsDocument(getOutputDir() + outputFileName, options, false);

//Create graphics path from the first rectangle
GeneralPath path = new GeneralPath();
path.append(new Rectangle2D.Float(250, 100, 150, 100), false);
//Set paint
document.setPaint(Color.ORANGE);
//Fill the rectangle
document.fill(path);

//Create graphics path from the second rectangle
path = new GeneralPath();
path.append(new Rectangle2D.Float(250, 300, 150, 100), false);
//Set stroke
document.setStroke(new java.awt.BasicStroke(3));
//Stroke (outline) the rectangle
document.draw(path);

//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:

// Add ellipse to PS document.

String outputFileName = "AddEllipse_outPS.ps";

//Create save options with A4 size
PsSaveOptions options = new PsSaveOptions();

// Create new 1-paged PS Document
PsDocument document = new PsDocument(getOutputDir() + outputFileName, options, false);

//Create graphics path from the first ellipse
GeneralPath path = new GeneralPath();
path.append(new java.awt.geom.Ellipse2D.Float(250, 100, 150, 100), false);
//Set paint
document.setPaint(Color.ORANGE);
//Fill the ellipse
document.fill(path);

//Create graphics path from the second ellipse
path = new GeneralPath();
path.append(new java.awt.geom.Ellipse2D.Float(250, 300, 150, 100), false);
//Set stroke
document.setStroke(new java.awt.BasicStroke(3));
//Stroke (outline) the ellipse
document.draw(path);

//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.
