Hi,

You'll need your own custom dialogs for these things.

On zooming, use $dc->SetUserScale.

For example

$dc->SetUserScale(0.5,0.5)

zooms to 50%.

You have to call SetUserScale everytime you use the dc, so in addition to in your drawing routines it also needs to go into your mouse events routines BEFORE you call $event->GetLogicalPosition( $dc );
