ABCpdf .NET PDF Component Documentation - VectorizeTextOperation Vectorize Function. Vectorizes the text glyphs in the pages of a document.

Vectorize Method

Vectorizes the text glyphs in the pages of a document.

Syntax

[C#]
void Vectorize(Doc doc) void Vectorize(Pages pages) void Vectorize(Page page)
[Visual Basic]
Sub Vectorize(doc As Doc) Sub Vectorize(pages As Pages) Sub Vectorize(page As Page)

may throw Exception()

Params

Name	Description
doc	The document containing the pages of text to be vectorized.
pages	The pages of text to be vectorized as referenced by a Pages IndirectObject.
page	The page of text to be vectorized as referenced by a Page IndirectObject.

Notes

Vectorizes the text glyphs on pages in the document.

The VectorizeTextOperation operation removes font glyphs and replaces them with polygonal outlines that appear the same.

The Operation.ProcessingObject property is used to give the user some control over which fonts would be vectorized. Setting the ProcessingObjectEventArgs.Cancel to 'true' turns off the vectorization for the particular font that's passed in to the Processing method (see examples below)

Please see the FontObject class for more information on the ProcessingObjectEventArgs.Object argument

The Operation.ProcessedObject property is not used with this operation

Example

Here we vectorize all the text in the document.


static void VectorizeDocText(string inDocName) {
  VectorizeTextOperation vecOp = new VectorizeTextOperation();
  Doc doc = new Doc();
  doc.Read(Server.MapPath(inDocName));
  vecOp.Vectorize(doc);
  doc.Save(Server.MapPath("VectorizedSample.pdf"));
}


  Dim vecOp As New VectorizeTextOperation()
  Dim doc As New Doc()
  doc.Read(Server.MapPath("../mypics/sample.pdf"))
  vecOp.Vectorize(doc)
  doc.Save(Server.MapPath("../mypics/VectorizedSample.pdf"))

Here we Vectorize all but the bold text.


static void Vectorizing(object sender, ProcessingObjectEventArgs e) {
  FontObject theFont = e.Object as FontObject;
  if (theFont != null && theFont.BaseFont.Contains("Bold"))
    e.Cancel = true;
}
static void VectorizeDocText(string inDocName) {
  VectorizeTextOperation vecOp = new VectorizeTextOperation();
  Doc doc = new Doc();
  doc.Read(Server.MapPath(inDocName));
  // Use the 'Vectorizing' method to decide which fonts to vectorize
  vecOp.ProcessingObject += new ProcessingObjectEventHandler(Vectorizing);
  vecOp.Vectorize(doc);
  doc.Save(Server.MapPath("VectorizedSample.pdf"));
}


Private Shared Sub Vectorizing(ByVal sender As Object, ByVal e As ProcessingObjectEventArgs)
  Dim theFont As FontObject = TryCast(e.Object, FontObject)
  If theFont IsNot Nothing AndAlso theFont.BaseFont.Contains("Bold") Then e.Cancel = True
End Sub

Private Shared Sub VectorizeDocText(ByVal inDocName As String)
  Dim vecOp As VectorizeTextOperation = New VectorizeTextOperation()
  Dim doc As Doc = New Doc()
  doc.Read(Server.MapPath(inDocName))
  vecOp.ProcessingObject += New ProcessingObjectEventHandler(AddressOf Vectorizing)
  vecOp.Vectorize(doc)
  doc.Save(Server.MapPath("VectorizedSample.pdf"))
End Sub

Vectorize all the external fonts.


static void Vectorizing(object sender, ProcessingObjectEventArgs e) {
  FontObject theFont = e.Object as FontObject;
  if (theFont != null && theFont.EmbeddedFont != null)
    e.Cancel = true;
}
static void VectorizeDocText(string inDocName) {
  VectorizeTextOperation vecOp = new VectorizeTextOperation();
  Doc doc = new Doc();
  doc.Read(Server.MapPath(inDocName));
  // Use the 'Vectorizing' method to decide which fonts to vectorize
  vecOp.ProcessingObject += new ProcessingObjectEventHandler(Vectorizing);
  vecOp.Vectorize(doc);
  doc.Save(Server.MapPath("VectorizedSample.pdf"));
}


Private Shared Sub Vectorizing(ByVal sender As Object, ByVal e As ProcessingObjectEventArgs)
  Dim theFont As FontObject = TryCast(e.Object, FontObject)
  If theFont IsNot Nothing AndAlso theFont.EmbeddedFont IsNot Nothing Then e.Cancel = True
End Sub

Private Shared Sub VectorizeDocText(ByVal inDocName As String)
  Dim vecOp As VectorizeTextOperation = New VectorizeTextOperation()
  Dim doc As Doc = New Doc()
  doc.Read(Server.MapPath(inDocName))
  vecOp.ProcessingObject += New ProcessingObjectEventHandler(AddressOf Vectorizing)
  vecOp.Vectorize(doc)
  doc.Save(Server.MapPath("VectorizedSample.pdf"))
End Sub
