Spire.PDF 3.9.360 supports to print the specific page on the PDF

We are pleased to announce a new hotfix version-Spire.PDF 3.9.360 today. In this version, we add new features to print the specific page and expose the name property of the layer. We also do some adjustments for the print function, the PDF layer and the PDF security feature. We also focus on fixing the bugs especially for the conversion from PDF to XPS, image to PDF and the compression the images in PDF file. Viewing the following full description of its enhanced features:

New Features:

• Support to print specific page.

PdfDocument doc = new PdfDocument();
doc.LoadFromFile(filename);
doc.PrintSettings.SelectSomePages(new int[]{2,4});
doc.Print();

• Expose the name property of the layer.

string name = doc.Layers[0].Name;

• Support to set the alignment for the signature content.

signature.SignTextAlignment=SignTextAlignment.Right;

• Support to get the text by document structure.

PdfDocument doc = new PdfDocument();
doc.LoadFromFile("Alcontrol - EDF.pdf");
PdfPageBase page = doc.Pages[0];
SimpleTextExtractionStrategy strategy = new SimpleTextExtractionStrategy();
string text = page.ExtractText(strategy);
FileStream fs = new FileStream("Alcontrol - EDF.txt", FileMode.Create);
StreamWriter sw = new StreamWriter(fs);
sw.Write(text);
sw.Flush();

Adjustments:

• The PrintDocument object has been marked as obsolete, it only needs to set the PrintSettings when print. Example:

PdfDocument doc = new PdfDocument(FilePath + "sample.pdf");
//change print settings you want
doc.PrintSettings.Landscape = true;
doc.Print();

• The pageLayers object of Page has been marked as obsolete, use Layers object under PdfDocument instead. It must create the Graphics for the Layer with the CreateGraphics method when Add Layer. Example:/li>

  //add layer
  PdfLayer layer = doc.Layers.AddLayer("red line", PdfVisibility.On);
  PdfCanvas pcA = layer.CreateGraphics(doc.Pages[0].Canvas);
  pcA.DrawLine(new PdfPen(PdfBrushes.Red, 1), new PointF(0, 100), new PointF(100, 100));
  layer = doc.Layers.AddLayer("blue line");
  PdfCanvas pcB = layer.CreateGraphics(doc.Pages[0].Canvas);
  pcB.DrawLine(new PdfPen(PdfBrushes.Blue, 1), new PointF(0, 150), new PointF(100, 150));
  //remove the layer by name
  doc.Layers.RemoveLayer(("red line"));
