[Jprogramming] High quality graphics files (& glfile)

[Shaw, Ewart]

Many thanks.  I can convert the BMP files to PNG using Paint Shop Pro,
so (space willing) it's a good alternative to producing PNG directly,
though I'd still prefer some form of vector graphics format.

The EMF files produced by plot still look low resolution (e.g. dashed lines
have individual segments interpolated beautifully between crudely placed endpoints),
so I think I'll need to use low-level graphics.  Did you (Devon) get glfile to work?

Mr. Shaw -

you can save arbitrarily large plots by specifying (width height) when
saving as a bitmap, e.g.
   pd 'save bmp \amisc\bigpic.bmp 2000 2000'
(you do have to "pd 'show'" before saving as I just discovered.)

The EMF format seems to work in J6.01 for the simple test I just did.  This allows
one to look at the file in an arbitrary size when opening it.  So, far I haven't been
able to figure out if this handles fine resolution well as I can only open an image of
2458 by 1912 (a multiple related to my screen size) before running into memory
limitations.

Hope this helps,

Devon McCormick
