THPDFViewerModel Metafile Methods

Creates scalable enhanced metafiles for loaded PDF pages without a Viewer control

Declarations

function CreatePageMetafile(PageIndex: Integer; DPI: Integer= 150): TMetafile;
function CreateCurrentPageMetafile(DPI: Integer= 150): TMetafile;

Usage notes

• The caller owns and must free each returned TMetafile and DPI is clamped from 12 through 2400
• DPI values are clamped from 12 through 2400
• Invalid document or page state returns nil
• Text and vector paths remain scalable EMF records
• The active ViewRotation is applied without changing the loaded PDF page
• Rotation by 90 or 270 degrees swaps the physical metafile width and height

Example

Metafile := Viewer.Model.CreateCurrentPageMetafile(300);
try
  Metafile.SaveToFile('current-view.emf');
finally
  Metafile.Free;
end;
