Modify Document

Hello,

I have a question.

So I am converting this .swf object which is a "Parts Diagram"  to HTML5/Canvas. But this .swf object is too small that I have to modify the document settings. In the document setting I have to mess around with the stage size width and height. Well I get the diagram or .swf object to to be bigger but isn't very responsive because the width and height are set to pixels. So at first the diagram or .swf object stage is set to width 650 and height 650 and the content is very hard to read. So I had to modify the document setting to width 1900 height 1900 to be able to do anything with it. But I don't think this is the right way to be doing this

Hopefully this makes sense.

Thank you,
