Try setting lfWidth to 0, that should then scale the font isotropically - setting a non-zero lfWidth can result in different scaling factors in the x and y directions. So for example if you leave width set to the normal width and only multiply up the height then the font will only be scaled in the y direction. Huw. -- Huw Davies [EMAIL PROTECTED]
