Previously, everything in JLink library needed to be set in size using pixels. Developers may be interested to look at the JLPage class as they can now specify page size using real world measurements. You want to set the on-screen image to be 23.5cm wide? No problem! Specify the units in the setJLPageSize() function and it will calculate how many pixels are needed to make the page 23.5cm on screen. It even handles rounding of units to the nearest pixel.
