Creation Parameters

title
printpage_rid This parameter is the routine_id for a function that will be called when a page needs to be printed. The function should take three arguments: this, page_num and dc. You should draw the page into the supplied dc. If you want to cancel the job return a value of zero. Otherwise, you should return a value of 1.
print_prepare_rid This parameter is the routine_id for a procedure that will be called when a page needs to be printed. It should take two arguments, a wxPrintout object and a DC. You can use this routine to determine the number of pages required, if you need the DC in order to do so. You should then call set_page_info() so that the correct number of pages will be used. If you don't need this, you can set this parameter to -1, which is the default value.
page_range [= {1,1}]

[func]
get_page_pixels ( atom printout )

Category: wxPrintout

Returns the size of the printer page in pixels. These may not be the same as the values returned from wxDC::GetSize if the printout is being used for previewing, since in this case, a memory device context is used, using a bitmap size reflecting the current preview zoom. The application must take this discrepancy into account if previewing is to be supported.

[func]
get_ppi_printer ( atom printout )

Category: wxPrintout

Returns the number of pixels per logical inch of the printer device context. Dividing the printer PPI by the screen PPI can give a suitable scaling factor for drawing text onto the printer. Remember to multiply this by a scaling factor to take the preview DC size into account.

Returns the number of pixels per logical inch of the screen device context. Dividing the printer PPI by the screen PPI can give a suitable scaling factor for drawing text onto the printer. Remember to multiply this by a scaling factor to take the preview DC size into account.
