-.AP double canvasY in

-A Tcl interpreter;  Postscript is appended to its result, or the

-.AP int numPoints in

-.SH DESCRIPTION
-.PP
-These procedures are called by canvas type managers to carry out
-common functions related to generating Postscript.
-Most of the procedures take a \fIcanvas\fR argument, which
-refers to a canvas widget for which Postscript is being
-generated.
-.PP
-\fBTk_CanvasPsY\fR takes as argument a y-coordinate in the space of
-a canvas and returns the value that should be used for that point
-in the Postscript currently being generated for \fIcanvas\fR.
-Y coordinates require transformation because Postscript uses an
-origin at the lower-left corner whereas X uses an origin at the
-upper-left corner.
-Canvas x coordinates can be used directly in Postscript without
-transformation.
-.PP
-\fBTk_CanvasPsBitmap\fR generates Postscript to describe a region
-of a bitmap.
-The Postscript is generated in proper image data format for Postscript,
-i.e., as data between angle brackets, one bit per pixel.
-The Postscript is appended to \fIinterp->result\fR and \fBTCL_OK\fR is returned
-unless an error occurs, in which case \fBTCL_ERROR\fR is returned and
-\fIinterp->result\fR is overwritten with an error message.
-.PP
-\fBTk_CanvasPsColor\fR generates Postscript to set the current color
-to correspond to its \fIcolorPtr\fR argument, taking into account any
-color map specified in the \fBpostscript\fR command.
-It appends the Postscript to \fIinterp->result\fR and returns
-\fBTCL_OK\fR unless an error occurs, in which case \fBTCL_ERROR\fR is returned and
-\fIinterp->result\fR is overwritten with an error message.
-.PP
-\fBTk_CanvasPsFont\fR generates Postscript that sets the current font
-to match \fItkFont\fR as closely as possible.
-\fBTk_CanvasPsFont\fR takes into account any font map specified
-in the \fBpostscript\fR command, and it does
-the best it can at mapping X fonts to Postscript fonts.
-It appends the Postscript to \fIinterp->result\fR and returns \fBTCL_OK\fR
-unless an error occurs, in which case \fBTCL_ERROR\fR is returned and
-\fIinterp->result\fR is overwritten with an error message.
-.PP
-\fBTk_CanvasPsPath\fR generates Postscript to set the current path
-to the set of points given by \fIcoordPtr\fR and \fInumPoints\fR.
-It appends the resulting Postscript to \fIinterp->result\fR.
-.PP
-\fBTk_CanvasPsStipple\fR generates Postscript that will fill the
-current path in stippled fashion.
-It uses \fIbitmap\fR as the stipple pattern and the current Postscript
-color;  ones in the stipple bitmap are drawn in the current color, and
-zeroes are not drawn at all.
-The Postscript is appended to \fIinterp->result\fR and \fBTCL_OK\fR is
-returned, unless an error occurs, in which case \fBTCL_ERROR\fR is returned and
-\fIinterp->result\fR is overwritten with an error message.
