Each page is a metafile, so you can edit it.

I can edit each page ?

Can i seek the first page and make this :
print.canevas.textout(150,150,'Text');

i can't reedit my page for insert the n# total of my pages

Thanks
David

ps : i try to add after 2 pages in manual mode (drawtext, textout,...), to insert a RTF document, it's no a problem ?

if you would i can send you the source code

I added BeginEdit and EndEdit methods to the control's interface. Using these methods, editing an existing page is similar to its creation.

For example, the following code can be used for your purpose:

Code: Select all
with PrintPreview do
  for PageNo := 1 to TotalPages do
    if BeginEdit(PageNo) then
      try
        // Use Canvas to draw on the page
      finally
        EndEdit;
      end;

By the way, while editing a page, PrintPreview.State property is psEditing.

Cheers,
Kambiz
