You pretty much can't. You need to think a bit laterally. Add a Panel to your form and set its Size to whatever area you want the user to see of the picture. Add a PictureBox to that Panel and set its SizeMode to Zoom. When you load an Image into the PictureBox, set its Size appropriately to just accommodate the whole thing. You can now change the Top and Left of the PictureBox to pan and the Size to zoom.
