Hi Geoff,
LayerPrinter2 allows you to specify the number of pixels. It really only
lets you make the (virtual) window larger before using the Save Image As
feature. It does reset the view bounds to the new larger area, and since
you only specify a single number for the pixel extent, it applies that to
the larger dimension and scales the other appropriately. So effectively,
you now have a new view panel with the same height to width ratio, but with
a larger pixel extent.
Since I haven't studied the Java Printing interfaces, I don't have any
advice on how to get the printer to put the LayerPrinter2 image into the
appropriate format so that it scales correctly. Personally, I would be
happy if it just prints correctly and the graphic scale is correct. The
line size and text size is not important to me as long as the text remains
readable, and the lines don't disappear.
About WMS, I don't use it much and can't seem so get any older links to
work right now. However, with LayerPrinter2 it should render correctly.
regards,
Larry

Dear Larry
I have noticed some more issues that you might have seen:
1. If I load a raster layer (using the
de.fhOsnabruek.jump.pirol.plugIns.PirolRasterImage plugin) then my
"quality" options produces a correctly scaled image, while your "accurate"
LayerPrinter2 class does not scale the image at all!- it appears to come out
"natural" size - any thoughts on how to correctly scale the image?
2. I have also tried printing a WMS layer but that did not work at
all. Has anyone tried this?? I am not sure how to get access to the WMS
image.
3. I use pdf995 as my PDF printer driver - it produces multi-page
images without problems

Hmm, I see what you mean. In your attached files, I completely agree
that SampleQuality.pdf has more resolution, however I'm not duplicating
your results. In fact, I can't seem to get it to work with my CutePDF
driver very well at all. I don't seem to be able to get multiple page
output unless I print to a real printer.
It seems strange that LayerPrinter2 would give you screen resolution
since its whole point is to allow you to specify whatever number of pixels
you want. I mainly use it to save user specified resolution png files.
