Could be because we had to round down for 26 but up for 15 though the effect should be minimal. And of course, if you swap the resolutions around the result is going to be some form of garbage. The device sends the same data, but when you swap it you're saying "15 device units along the x are 1mm" which is obviously incorrect and stretches things.</pre> </div> <hr> You are receiving this mail because: <ul> <li>You are the assignee for the bug.</li> </ul> </body> </html>
