If you look above, I wrote: > You define a resolution: > > Note: assuming DPI 96 > > which means that each pixel is exactly 1/96 in ~ 0.264583 mm. You see that 96 pixels per inch doesn't mean some "round" number of pixels per cm: 96 PPI = 37.7952755905512... pixels per cm. When you switch from in to cm in the resolution, the control shows a rounded (down) value, but internally the resolution is still exactly 96 PPI - which is *correct*, because user might need just to check some different units without actually change the resolution. However, when user starts to *modify* the resolution using the new units, the new value is the integral number of pixels per unit - and when you select 37 again, it is true 37 pixels per cm, not the initial 37.7952755905512... which you started with. Hence the difference in the size - which is again OK. -- You are receiving this mail because: You are the assignee for the bug.
