Re:TPaintbox.Canvas or MainForm.Canvas faster???
Hmm.. A canvas is a canvas is a canvas, I think. I'm working on a vector
tool that maintains the objects in a queue, draws them to a TBitmap, then
Blt's the bitmap onto my control's canvas. This solves a flicker problem,
but actually results in a decrease in speed due to the overhead from the
extra BLT operation.
To my knowledge, there should not be a difference in speed between a
Paintbox's canvas and a form's canvas, unless the form's canvas contains
controls. I'd recommed using either the paintbox or a custom control just
for the sake of organization and maintenance, though.
