Arrow command/ velovect plot resolution [message #26678]

Hi, could anyone help me with improving the resolution of a vector plot? I have
tried velovect etc and the standard commands and am now using arrow direct.
This looks just about OK on the screen, but screen grabs using WRITE_JPEG with
quality = 100 or the Windows clipboard look worse.

The plot area is defined with a draw widget and is 1500 x 1000 pixels in size
so I would expect to get better quality graphics. The text label was improved
by switching to a vector font, but is still a bit square looking. The other
plot types are very nice quality.

Thanks for the ideas. Just to give you a bit more of an idea I am trying to
create graphics that can be pasted or inserted into a MS Word document. I have
tried all the different arrow commands e.g. thick, and also different file save
types.

I know it is possible to produce a good quality vectot or arrow graphs with the
same data with other applications e.g. Mathematica, but unfortunately I want a
single software application to do this and the contour plots etc in IDL seem to
be the best by far.

I can't seem to increase the plot resolution other than by making the plot are
beigger than the screen display area but when I do this IDL seems to crash or
do random things.
