Deletion Example

This example shows how to delete pages from a PDF document.

First we create an ABCpdf Doc object and read our source document. We store the number of pages we're going to delete - we're going to delete all but one.

[C#]
Doc theDoc = new Doc();
theDoc.Read(Server.MapPath("../mypics/sample.pdf"));
int theCount = theDoc.PageCount - 1;

[Visual Basic]
Dim theDoc As Doc = New Doc()
theDoc.Read(Server.MapPath("../mypics/sample.pdf"))
Dim theCount As Integer = theDoc.PageCount - 1


We go round a loop deleting the second page each time.

[C#]
for (int i = 0; i < theCount; i++) {
  theDoc.PageNumber = 2;
  theDoc.Delete(theDoc.Page);
}

[Visual Basic]
For i As Integer = 1 to theCount
  theDoc.PageNumber = 2
  theDoc.Delete(theDoc.Page)
Next


We add some text to the PDF so that we know how many pages we've deleted. Finally we save the PDF.

[C#]
theDoc.FontSize = 500;
theDoc.Color.String = "255 0 0";
theDoc.TextStyle.HPos = 0.5;
theDoc.TextStyle.VPos = 0.3;
theDoc.AddText(theCount.ToString());
theDoc.Save(Server.MapPath("deletion.pdf"));
theDoc.Clear();

[Visual Basic]
theDoc.FontSize = 500
theDoc.Color.String = "255 0 0"
theDoc.TextStyle.HPos = 0.5
theDoc.TextStyle.VPos = 0.3
theDoc.AddText(theCount.ToString())
theDoc.Save(Server.MapPath("deletion.pdf"))
theDoc.Clear()
