A Document object is created to make a readable version of the PDF.

Add the copied page to the canvas using the method addXObject(PdfXObject xObject, float x, float y).

Copy the content from the original page using the method copyAsFormXObject(PdfDocument shrunkenDocument)(returns a PdfFormXObject) present in the PdfPage class.Add the above-created matrix with scaled downsizes to the empty canvas.Initialize the PdfCanvas object by passing in the empty page as the parameter.Import PdfCanvas from the package .canvas.Append the shrunken version of the original page to the empty PDF. The static method getScaleInstance(double width, double height) present in the AffineTransform class returns an AffineTransform object with scaled width and scaled height.ħ.New scaled height can be calculated using (emptyPageHeight/originalPageHeight)/2.New scaled width can be calculated using (emptyPageWidth/originalPageWidth)/2.Import AffineTransform from the package.Creating the shrunken version of the original page. addNewPage() methods returns a PdfPage object.Ħ.

Initialize the PdfDocument by passing the PdfWriter object.ģ.
