GetPageAsMetafile Method

Declaration

int GetPageAsMetafile(int PageNr,int Options);

Description

Creates a meta file from a certain page and returns the handle. Please call Memo.ReformatAll(false,false) if the editor was dynamically created.

To create a file use SavePageAsMetafile.

Parameters:

PageNr :        The number of the page to be saved. The first is 0.

Options:        a bit field:

4: display a frame for the page margins

8: optimized for PDF export. We recommend to always set this bit!

16: also print selection marker

32: do not print watermarks

64: do not print header and footer

128: do not print images

256: print table grid lines.

512: Export embedded meta-files as bitmaps

Returns

The handle to an enhanced metafile. If an error happens the return value is 0. The handle must be freed by the caller.

This C# function can be used to load a metafile from a handle into picture box:

private void LoadInImage(System.Windows.Forms.PictureBox PictureBox, int MetaHandle)

{

 if (MetaHandle!=0)

 {

  Metafile aMetafile=new Metafile(new IntPtr(MetaHandle), true);

  PictureBox.Image = aMetafile;

  PictureBox.SizeMode =  PictureBoxSizeMode.StretchImage;

 }

 else PictureBox.Image = null;

}

You can use it in code like this:

LoadInImage(pictureBox1,

 wpdllInt1.Memo.GetPageAsMetafile(0,0));

Example using a dynamic editor:

   WPDLLInt temp_editor = new WPDLLInt(); 

   temp_editor.Memo.LoadFromString( data_provided_as_string , false, "AUTO");

   temp_editor.SpecialTextAttr(SpecialTextSel.wpInsertpoints).Hidden = true;

   temp_editor.Memo.ReformatAll(true, false);

   for(int i = 0; i < temp_editor.Memo.TextCursor.PageCount; i++)

   {

            IntPtr metaHandle = temp_editor.Memo.GetPageAsMetafile(i, 8);

            if (metaHandle.ToInt32() == 0)

            {

                     Console.WriteLine("page " + i.ToString() + " not loaded");

            }

            else

            {

                     System.Drawing.Imaging.Metafile aMetafile = new System.Drawing.Imaging.Metafile(metaHandle, true);

                     aMetafile.Save("c:\\page__" + i.ToString() + ".emf");

            }

   }

   temp_editor.DisposeEditor();
