How do I set the width, height, & viewBox

Hi all;

How can I set the width & height in inches? And how can I set the viewBox?

I want the <svg> element to have: width="2in" height="4in" viewBox="0 0 1828800 1828800"

The reason I need this is I know the size of my SVG object. And I am passing all units for all renders in EMUs (914400/inch). So I can create the SVG canvas size in EMUs, write all objects using EMUs. Then setting the viewBox makes that all map correctly. Setting the size in inches then takes that to the size of the final object I want.

thanks - dave

The viewBox feature is missing, it has been raised by another user also:

https://github.com/jfree/jfreesvg/pull/4

I'll get this feature into the next release most likely.

Please consider adding the ability to set the width/height in units too.

thanks - dave

I'll research that. I guess that if the units are specified then that will also need to be synchronised with a translation on the Graphics2D instance so that the drawing units are consistent. Or how do you see that working?

No, I just need to set it at the end. I render the entire SVG using EMUs for all coordinates and telling it the size in EMUs. But think of the entire rendering as occurring in arbitrary units.

Then when I'm done I use the viewBox to give the size of those arbitrary units and set the width/height to physical inches so it knows the viewBox -> physical scaling.

Hi David,

I just pushed some changes to GitHub that I hope will meet your requirements. Please take a look and let me know...if all is good I'll release version 3.2.
