Original Article

Printing images using DotImage (ImagePrintDocument) or DotAnnotate (AnnotatePrintDocument) does not allow for printing of a specific page range other than all of the pages. This article will explain how to work around this, focusing on the AnnotatePrintDocument class, but this can be easily translated to using on ImagePrintDocument.

Since the AnnotatePrintDocument class can only print all the the images it has, we must make an extra effort to enable printing of a page range. The idea here is to simply create an AnnotatePrintDocument with only the pages we want to print in it. Here are the steps we should take:

1. Create an AnnotatePrintDocument with all images and annotations
2. Show the PrintDialog to let the user select the print options
3. Create a new ImageCollection containing only the selected pages, and a new AnnotationController containing the corrasponding Annotation layers
4. Set the AnnotatePrintDocument to use the new ImageCollection and AnnotationController objects
5. Start the Printing

Although the most complicated step is creating the new Collection of Images and Annotations, this is still very straight forward. The code listed below can be copied directly into the DotAnnotate Demo:

[C#]

// STEP 1: Create annotatePrintDocumentannotatePrintDocument1.SetImagesFromImageCollection(this.annotateViewer1.Images);
annotatePrintDocument1.Annotations = this.annotateViewer1.Annotations;
annotatePrintDocument1.ScaleMode = Atalasoft.Imaging.WinControls.PrintScaleMode.FitToEdges;
annotatePrintDocument1.Center = false;

// STEP 2: Show the printer dialog.PrintDialog dlg = new PrintDialog();
dlg.AllowSomePages = true;
dlg.Document = annotatePrintDocument1;
dlg.PrinterSettings.FromPage = 1;
dlg.PrinterSettings.ToPage = this.annotateViewer1.Images.Count;
dlg.PrinterSettings.MinimumPage = 1;
dlg.PrinterSettings.MaximumPage = this.annotateViewer1.Images.Count;
if (dlg.ShowDialog(this) == DialogResult.OK)
{     // if not printing all pages, create Image Collection     int fromPage = dlg.PrinterSettings.FromPage;
     int toPage = dlg.PrinterSettings.ToPage;

     // STEP 3: Create new ImageCollection and Annotationcontroler
     AnnotationController ann = new AnnotationController();

     int pageNumber = 0;
     ImageCollection printImages = new ImageCollection();
     for(int i = fromPage-1; i < toPage;  i++)     
     {
         printImages.Insert(pageNumber, this.annotateViewer1.Images[i]);
         ann.Layers.Insert(pageNumber, this.annotateViewer1.Annotations.Layers[i]);
         pageNumber++;
     }
     
     // STEP 4: Set new Images/annotations
     annotatePrintDocument1.SetImagesFromImageCollection( printImages );
     annotatePrintDocument1.Annotations = ann;
     
     // STEP 5: Print the pages
     annotatePrintDocument1.Print();
}
dlg.Dispose();
