Hi,
I want to print a IDLgrScene object using IDLgrPrinter on
{ sparc sunos unix 5.1 Apr 13 1998}
The scene contains several polygons with textures. Each polygon use a
specific color table (IDLgrPalette) for its texture.
I could only print (or save in a file) in black/white. I found no way to
print in color. Does somebody know how to print in color?
Any help will be appreciated.

Hello (head hanging low),
I'm not sure if answering my own question indicates that I'm
clever or slow. I don't think I want to know.
The correct way to control the size of graphics for the printer
(and the clipboard) is to control the dimensions and location of
the View that is being rendered.
r = dialog_printersetup(myprinterobject)
if r = 1 then begin
myview->getproperty, location = wloc, dimensions = wdim
myprinterobject->getproperty, dimensions = pdim
;to get a square plot... choose the smaller of pdim
;reduce its size a bit to get a decent margin
viewdim = min(pdim) *0.8
;position the graphic by controlling the LOCATION
myview->setproperty, dimension = viewdim, location =
pdim*0.1
myprinterobject->newpage
myprinterobject->draw, myview
myprinterobject->newdocument
;restore the original view dimensions
myview->setproperty, location = wloc, dimensions = wdim
endif
So, it does seem to be a analogous to the controlling the
direct graphics device PRINTER.
Phew! Now, if I could just find that pointer I lost...
