Hello,

does anybody know a way to render a PDF page to Firemonkey TImage?

in Delphi DCL I go this way:

FDebenu.RenderPageToDC(72, 1, imCanvas.Canvas.Handle);

but in FMX I have no direct access to Image's Device Context...

pls show me the way.

Thanks a lot.

Possible solution:

procedure TfrmPdfFormEditor.RenderDocument(page: Integer);

var

ms: TMemoryStream;

begin

ms := TMemoryStream.Create;

FDebenu.RenderPageToStream(72, page, 0, ms);

ms.Position := 0;

imCanvas.Bitmap.LoadFromStream(ms);

ms.Free;

end;

Works for me.
