How can I get the size of the page, I'm going to print on, in pixels? I need
this in the functions wxPrintout.OnPreparePrinting() to calculate the number of
pages I have in my document and in wxPrintout.OnPrintPage().
P.S. Please, don't say wxPrintout.GetPageSizePixels() ! It is returning
something like 27098x28956 I can hardly imagine how i can stuff the page of
this size into my poor printer

How can I get the size of the page, I'm going to print on, in pixels? I need
this in the functions wxPrintout.OnPreparePrinting() to calculate the number of
pages I have in my document and in wxPrintout.OnPrintPage().
In my app I'm getting the page size during OnPrintPage() like this:
dc = self.GetDC()
width, height = dc.GetSizeTuple()
... But I suppose that probably won't work in OnPreparePrinting() -- in my case, I
know that I will only ever be printing a single page.
P.S. Please, don't say wxPrintout.GetPageSizePixels() ! It is returning
something like 27098x28956 I can hardly imagine how i can stuff the page of
this size into my poor printer
Hm, even at 600dpi that's 45.16in x 48.26in -- something does seem odd there.
Are you setting your print data properly? Try something along these lines, if you
don't already have it....
self.printdata = wxPrintData()
self.printdata.SetPaperId(wxPAPER_LETTER)
self.printdata.SetQuality(200) # or whatever dpi your printer handles
[...]
pdd = wxPrintDialogData()
pdd.SetPrintData(self.printdata)
printer = wxPrinter(pdd)
[...]
printout = MyPrintout.MyPrintout(...)
[...]
if not printer.Print(self.GetTopWindow(), printout):
wxMessageBox("There was a problem printing.\nPerhaps your current
printer is not set correctly?", "Printing", wxOK)
else:
self.printdata = printer.GetPrintDialogData().GetPrintData()
printout.Destroy()
By explicitly setting the paper size and print quality, you *might* end up getting
a more reasonable result from GetPageSizePixels() ... (Unless, of course,
GetPageSizePixels() relies on some other information that is not yet available
during OnPreparePrinting(), in which case you'll need something different.)
