[ncl-talk] PDF plot to big and rotated in 90 degrees.

[Mary Haley]

I didn't notice this before, but you can't use the wkWidth and wkHeight
resources with PS or PDF.  These width and height are for pixel sizes,
which apply to the X11 and PNG workstations only.

If you want an image to be a specific pixel size, then you need to use
"PNG" as the output. With PNG as the output, the image will not be rotated
automatically, so you don't need to set gsnPaperOrientation.

However, NCL always draws its images to a square, so your image is going to
be the smaller of the two sizes you specified: 1536 x 1536.

My suggestion is to set the size to 1700 x 1700, and then use ImageMagick
<http://www.imagemagick.org/script/index.php>'s "convert" to trim the
image.

I've attached a sample script.
