You are receiving the event location in the window, but you are converting
based on the content view. Pass NULL in fromView: to translate from window
coordinates to local coordinates. Then let PDFView do the heave lifting for you
to translate that point to a point on a page.
To convert the point to page coordinates use something to the effect of:
-(void)mouseDown:(NSEvent *)event
{
NSPoint mouseDownPoint = [self convertPoint:[event
locationInWindow] fromView:NULL];
PDFPage *mouseDownPage = [self pageForPoint:mouseDownPoint
nearest:NO];
NSPoint pagePoint = [self convertPoint: mouseDownPoint
toPage:mouseDownPage];
...
}
The above should work at any scale factor.
