Copy an image from a pdf file and paste to another position
This C#.NET example describes how to copy an image from one page of PDF document and paste it into another page.
String inputFilePath = Program.RootPath + "\\" + "2.pdf";
String outputFilePath = Program.RootPath + "\\" + "output.pdf";
PDFDocument doc = new PDFDocument(inputFilePath);
// get the first page
int pageIndex = 0;
PDFPage page1 = (PDFPage)doc.GetPage(pageIndex);
// select image at the position (480F, 550F) in the page
PointF cursorPos = new PointF(480F, 550F);
PDFImage image = PDFImageHandler.SelectImage(page1, cursorPos);
// copy the image
Bitmap anImage = (Bitmap)image.Image.Clone();
// get the second page
PDFPage page2 = (PDFPage)doc.GetPage(1);
// set image position in the page: X = 100F, Y = 400F
PointF position = new PointF(100F, 400F);
// add image to the page
PDFImageHandler.AddImage(page2, anImage, position);
// output the new document
doc.Save(outputFilePath);
Move an image in the PDF page using C#
The following C# source code shows how to move an image from one position to another in the same PDF page.
String inputFilePath = Program.RootPath + "\\" + "2.pdf";
String outputFilePath = Program.RootPath + "\\" + "output.pdf";
// open a document and select the page
PDFDocument doc = new PDFDocument(inputFilePath);
PDFPage page = (PDFPage)doc.GetPage(0);
// extract all images in the page
List<PDFImage> images = PDFImageHandler.ExtractImages(page);
// move the first image to position (0, 0) in the same page
PDFImageHandler.MoveImageTo(doc, images[0], 0, new PointF(0F, 0F));
// output the new document
doc.Save(outputFilePath);
Replace an image in the document
The following C# example code shows how to replace an image with another in the PDF page using C#
String inputFilePath = @"C:\1.pdf";
String outputFilePath = @"C:\output.pdf";
Bitmap bitmap = new Bitmap(@"C:\1.png");
// Open file and get the first page
PDFDocument doc = new PDFDocument(inputFilePath);
PDFPage page = (PDFPage)doc.GetPage(0);
// Select the image at position (70, 80).
PDFImage img = PDFImageHandler.SelectImage(page, new PointF(70, 80));
// Replace the selected image by the new image.
PDFImageHandler.ReplaceImage(page, img, bitmap);
doc.Save(outputFilePath);
