Because there are slight differences in how GDI and Tk's \fBcanvas\fR +widget display graphics, printed output from the \fBcanvas\fR on Windows may +not be identical to screen rendering. +.TP +\fBX11\fR +. +The X11 implementation uses a Tk GUI to configure print jobs for sending to a +printer via the +.QW "lpr" +or +.QW "lp" +commands. While these commands have a large number of parameters for +configuring print jobs, printers vary widely in how they support these +parameters. As a result, only printer selection and number of copies are +configured as arguments to the print command; many aspects of print rendering, +such as grayscale or color for the canvas, are instead configured when +PostScript is generated. +.SH "SEE ALSO" +canvas(n), text(n), tk(n) +.SH KEYWORDS +print, output, graphics, text, canvas diff --git a/doc/sysnotify.n b/doc/sysnotify.n index 2fa8cf0..ea1ab89 100644 --- a/doc/sysnotify.n +++ b/doc/sysnotify.n @@ -18,8 +18,10 @@ The \fBtk sysnotify\fR command creates a platform-specific system notification a .SH EXAMPLE .PP Here is an example of the \fBtk sysnotify\fR code: +.PP .CS - tk sysnotify "Alert" "This is just a test of the Tk System Notification Code." +tk sysnotify "Alert" \e + "This is just a test of the Tk System Notification Code." .CE .SH PLATFORM NOTES .PP @@ -28,17 +30,27 @@ API's.
