create to export jpg to scale (out by 1 or 2 pixels)
first test to utilise javascript in UI for preview purpose

Found a thread on a forum dated back to 2006 about exporting images to scale by setting camera.height the procedure is a lot simplier than f2f since it uses absolute values regardless of screen dpi settings

Modded it to export jpg to scale at a higher resolution. Export to scale – Some workround using the web dialog html+javascript UI to show how the final image fits to standard paper. It would require photoshop to produce the final image at desired dpi but such resizing will not incur quality loss because the resolution in pixels is exported at the final dpi.

There is quite a lot of problems with the original method of getting scaled drawings from skp models using layout or print to pdf. Where layout is actually quite good to work with visually, it is too slow. print to pdf sometimes produce artifacts (lines across) and the extend is limited to the pdf printer paper size, it also takes a long time to rasterise/open the pdf produced which doesn’t contain vector information. Another problem with printing to pdf is that it can only print to scale (accurately) when the section plane is aligned to the world xyz axis.
