[udig-devel] dpi issues

[Jody Garnett]

Hi Vince:

I have been thinking a bit more about this; and I agree with you that 
ApplicationGIS.drawMap() should "do the right thing" taking scale and so 
forth into account as needed.

It sounds like the issue of printing (from BIRT or iText) may need some 
additional control; my gut feeling is we should make some of the 
MapBoxPrinter / ExportMapToImageWizard functionality available for 
others to reuse as a separate issue. I have confirmed that the Rescale 
code has only been applied to trunk.
