Fl_Printer allows to use all FLTK drawing, color, text, and clip functions, and to have them operate
|
|
on printed page(s). There are two main, non exclusive, ways to use it.
|
|
<ul><li>Print any widget (standard, custom, Fl_Window, Fl_Gl_Window) as it appears
|
|
on screen, with optional translation, scaling and rotation. This is done by calling print_widget()
|
|
or print_window_part().
|
|
<li>Use a series of FLTK graphics commands (e.g., font, text, lines, colors, clip, image) to
|
|
compose a page appropriately shaped for printing.
|
|
</ul>
|
|
In both cases, begin by start_job(), start_page(), printable_rect() and origin() calls
|
|
and finish by end_page() and end_job() calls.
|
|
<p><b>Platform specifics</b>
|
|
<br>Fl_Printer is typedef'ed to Fl_PostScript_Printer under Unix/Linux
|
|
and to Fl_System_Printer otherwise. Both classes have the same API.
|
|
<ul>
|
|
<li>Unix/Linux platforms:
|
|
Class Fl_RGB_Image prints but loses its transparency if it has one.
|
|
See class Fl_PostScript_Graphics_Driver for a description of how UTF-8 strings appear in print.
|
|
Use the static public attributes of this class to set the print dialog to other languages
|
|
than English. For example, the "Printer:" dialog item Fl_Printer::dialog_printer can be set to French with:
|
|
\code
|
|
Fl_Printer::dialog_printer = "Imprimante:";
|
|
\endcode
|
|
before creation of the Fl_Printer object.
|
|
Use Fl_PostScript_File_Device::file_chooser_title to customize the title of the file chooser dialog that opens
|
|
when using the "Print To File" option of the print dialog.
|
|
<li>MSWindows platform: Transparent Fl_RGB_Image 's don't print with exact transparency on most printers.
|
|
Fl_RGB_Image 's don't rotate() well.
|
|
A workaround is to use the print_window_part() call.
|
|
<li>Mac OS X platform: all graphics requests print as on display.
|
|
</ul>
