Casting TPdfDocumentGDI VCLCanvas/TCanvas

Hello

MyProcedure has this paramters

destination: TCanvas;AusgabeNummer:Integer;ppdf:Boolean = false);

so, when ppdf is true then
I set destination to VCLCanvas.

My idea was something like this:

if ppdf then
destination :=getPdfObject.VCLCanvas;

Unfortunately it will be throw an access error.

Could someone help me?

Thanks,

loris

You need to add a page to have canvas instance.
