Add, Remove, Extract and Update Images in PDF using Java

add-image-to-pdf.java

// Open a document
Document pdfDocument1 = new Document("input.pdf");

// Set coordinates
int lowerLeftX = 100;
int lowerLeftY = 100;
int upperRightX = 200;
int upperRightY = 200;

// Get the page you want to add the image to
Page page = pdfDocument1.getPages().get_Item(1);

// Load image into stream
java.io.FileInputStream imageStream = new java.io.FileInputStream(new java.io.File("input_image1.jpg"));

// Add an image to the Images collection of the page resources
page.getResources().getImages().add(imageStream);

// Using the GSave operator: this operator saves current graphics state
page.getContents().add(new Operator.GSave());

// Create Rectangle and Matrix objects
Rectangle rectangle = new Rectangle(lowerLeftX, lowerLeftY, upperRightX, upperRightY);
Matrix matrix = new Matrix(new double[] { rectangle.getURX() - rectangle.getLLX(), 0, 0, rectangle.getURY() - rectangle.getLLY(), rectangle.getLLX(), rectangle.getLLY() });

// Using ConcatenateMatrix (concatenate matrix) operator: defines how image must be placed
page.getContents().add(new Operator.ConcatenateMatrix(matrix));
XImage ximage = page.getResources().getImages().get_Item(page.getResources().getImages().size());

// Using Do operator: this operator draws image
page.getContents().add(new Operator.Do(ximage.getName()));

// Using GRestore operator: this operator restores graphics state
page.getContents().add(new Operator.GRestore());

// Save the new PDF
pdfDocument1.save("Updated_document.pdf");

// Close image stream
imageStream.close();

extract-image-from-pdf.java

// Open a document
Document pdfDocument = new Document("input.pdf");

// Extract a particular image
XImage xImage = pdfDocument.getPages().get_Item(1).getResources().getImages().get_Item(1);

// Create stream object to save the output image
java.io.OutputStream output = new java.io.FileOutputStream("output.jpg");

// Save the output image
xImage.save(output);

// Close stream
output.close();

remove-image-from-pdf.java

// Open a document
Document pdfDocument = new Document("input.pdf");

// Delete a particular image
pdfDocument.getPages().get_Item(1).getResources().getImages().delete(1);

// Save the updated PDF file
pdfDocument.save("output.pdf");

replace-image-in-pdf.java

// Open a document
Document pdfDocument = new Document("input.pdf");

// Replace a particular image
pdfDocument.getPages().get_Item(1).getResources().getImages().replace(1, new java.io.FileInputStream(new java.io.File("aspose.png")));

// Save the updated PDF file
pdfDocument.save("output.pdf");
