I'm thinking about generalizing a bunch of printing procedures so they
would work with any Canvas, which would passed as a parameter, but I
CANNOT alter the caller's canvas. I thought this would do the trick but
some annoying doubts came to my mind:
procedure MyCanvasProc(ACanvas : TCanvas);
var
MyLocalCanvas : TCanvas;
begin
// Is the original canvas preserved ?
MyLocalCanvas := TCanvas; // What actually happens here ?
. . .
with MyLocalCanvas do
begin
write & draw a bunch of stuff...
end;
. . .
// Do I have to free anything here ?
end;
TIA,
Ronaldo
