.\" The -*- nroff -*- definitions below are for supplemental macros used
.\" in Tcl/Tk manual entries.
.\"
.\" .AP type name in/out ?indent?
.\" Start paragraph describing an argument to a library procedure.
.\" type is type of argument (int, etc.), in/out is either "in", "out",
.\" or "in/out" to describe whether procedure reads or modifies arg,
.\" and indent is equivalent to second arg of .IP (shouldn't ever be
.\" needed; use .AS below instead)
.\"
.\" .AS ?type? ?name?
.\" Give maximum sizes of arguments for setting tab stops. Type and
.\" name are examples of largest possible arguments that will be passed
.\" to .AP later. If args are omitted, default tab stops are used.
.\"
.\" .BS
.\" Start box enclosure. From here until next .BE, everything will be
.\" enclosed in one large box.
.\"
.\" .BE
.\" End of box enclosure.
.\"
.\" .CS
.\" Begin code excerpt.
.\"
.\" .CE
.\" End code excerpt.
.\"
.\" .VS ?version? ?br?
.\" Begin vertical sidebar, for use in marking newly-changed parts
.\" of man pages. The first argument is ignored and used for recording
.\" the version when the .VS was added, so that the sidebars can be
.\" found and removed when they reach a certain age. If another argument
.\" is present, then a line break is forced before starting the sidebar.
.\"
.\" .VE
.\" End of vertical sidebar.
.\"
.\" .DS
.\" Begin an indented unfilled display.
.\"
.\" .DE
.\" End of indented unfilled display.
.\"
.\" .SO ?manpage?
.\" Start of list of standard options for a Tk widget. The manpage
.\" argument defines where to look up the standard options; if
.\" omitted, defaults to "options". The options follow on successive
.\" lines, in three columns separated by tabs.
.\"
.\" .SE
.\" End of list of standard options for a Tk widget.
.\"
.\" .OP cmdName dbName dbClass
.\" Start of description of a specific option. cmdName gives the
.\" option's name as specified in the class command, dbName gives
.\" the option's name in the option database, and dbClass gives
.\" the option's class in the option database.
.\"
.\" .UL arg1 arg2
.\" Print arg1 underlined, then print arg2 normally.
.\"
.\" .QW arg1 ?arg2?
.\" Print arg1 in quotes, then arg2 normally (for trailing punctuation).
.\"
.\" .PQ arg1 ?arg2?
.\" Print an open parenthesis, arg1 in quotes, then arg2 normally
.\" (for trailing punctuation) and then a closing parenthesis.

.SH DESCRIPTION
This package provides a container class for generating \fIpdf\fR documents\&.
.SH COORDINATES
All coordinates and distances can be expressed with or without a unit\&. See
\fBUNITS\fR for valid units\&.
When the page is configured with \fB-orient\fR set to false, origin is in
the bottom left corner\&. With \fB-orient\fR true (the default), origin is in the top left
corner\&.
Origin is displaced to account for margins, i\&.e\&. if margins are 100,
the user coordinate (0,0) corresponds to (100,100) on the paper\&.
Page option \fB-orient\fR can also affect the anchor point for things like
images\&.
.SH UNITS
Any coordinates and distances can be expressed with or without an explicit
unit\&. If no unit is given, the default unit for the document is used\&.
A unit may be one of
\fBmm\fR (millimeter),
\fBm\fR (millimeter),
\fBcm\fR (centimeter),
\fBc\fR (centimeter),
\fBp\fR (points) or
\fBi\fR (inches)\&.
Commands returning coordinates or distances always return a double value
in the document's default unit\&.
.SH "PUBLIC API"
.SS "PACKAGE COMMANDS"
.TP
\fB::pdf4tcl::new\fR \fIobjectName\fR ?\fIoption value\fR\&.\&.\&.?
This command creates a new pdf4tcl object with an associated Tcl
command whose name is \fIobjectName\fR\&. This \fIobject\fR command is
explained in full detail in the sections \fBOBJECT COMMAND\fR
and \fBOBJECT METHODS\fR\&. The object command will be created
under the current namespace if the \fIobjectName\fR is not fully
qualified, and in the specified namespace otherwise\&.
If \fIobjectName\fR is %AUTO% a name will generated\&.
The return value is the newly created object's name\&.
.sp
The options and their values coming after the name of the object are
used to set the initial configuration of the object\&.
See \fBOBJECT CONFIGURATION\fR\&.
.TP
\fB::pdf4tcl::getPaperSize\fR \fIpaper\fR
This call returns the size of a named paper type, e\&.g\&. "a4"\&.
Paper names are case insensitive\&.
The argument \fIpaper\fR may also be a two element list
with values as accepted by \fB::pdf4tcl::getPoints\fR\&.
The return value is a list with width and height in points\&.
.TP
\fB::pdf4tcl::getPaperSizeList\fR
This call returns the list of known paper types\&.
.TP
\fB::pdf4tcl::getPoints\fR \fIval\fR
This call translates a measurement to points (1/72 inch)\&.
The format of \fIval\fR is '\fInum\fR ?\fIunit\fR?' where
\fInum\fR is a valid integer or double\&. See \fBUNITS\fR for valid
\fIunit\fRs\&. If no \fIunit\fR is given, the value is interpreted
as points\&.
.TP
\fB::pdf4tcl::loadBaseTrueTypeFont\fR \fIbasefontname\fR \fIttf_file_name\fR
This call loads a TTF font from file to be used by any pdf4tcl objects\&.
The \fIbasefontname\fR is used to reference this font\&.
To use this base font in documents, a font with some encoding must be
created from it using \fBcreateFont\fR or \fBcreateFontSpecEnc\fR\&.
.TP
\fB::pdf4tcl::createBaseTrueTypeFont\fR \fIbasefontname\fR \fIttf_data\fR
This call creates a base font from TTF binary data\&.
.TP
\fB::pdf4tcl::loadBaseType1Font\fR \fIbasefontname\fR \fIAFM_file_name\fR \fIPFB_file_name\fR
This call loads a Type1 font from two files (\&.afm and \&.pfb) to be used by
any pdf4tcl objects\&. The \fIbasefontname\fR is used to reference this font\&.
To use this base font in documents, a font with some encoding must be
created from it using \fBcreateFont\fR or \fBcreateFontSpecEnc\fR\&.
.TP
\fB::pdf4tcl::createBaseType1Font\fR \fIbasefontname\fR \fIAFM_data\fR \fIPFB_data\fR
This call creates a base font from AFM text and PFB binary data\&.
.TP
\fB::pdf4tcl::createFont\fR \fIbasefontname\fR \fIfontname\fR \fIencoding_name\fR
This call creates a font that can be used in documents from a base font\&. The given encoding
defines the (up to) 256 unicode characters that can be drawn when \fIfontname\fR is selected\&.
To use more characters, multiple fonts need to be created and selected based on what needs to be written\&.

drawn when \fIfontname\fR is selected\&.

\fB::pdf4tcl::getFonts\fR
This call returns the list of known font names, i\&.e\&. those accepted in a call
to \fBsetFont\fR\&.
This includes the default fonts and fonts created by e\&.g\&.
\fB::pdf4tcl::createFont\fR\&.
.TP
\fB::pdf4tcl::rgb2Cmyk\fR \fIrgb\fR
This call translates an RGB color value to a CMYK color value\&.
It is used internally if \fB-cmyk\fR was set at object creation to
translate colors\&.
You can redefine this procedure to provide your own translation\&.
.TP
\fB::pdf4tcl::cmyk2Rgb\fR \fIcmyk\fR
This call translates a CMYK color value to an RGB color value\&.
It is used internally to translate colors\&.
You can redefine this procedure to provide your own translation\&.
.TP
\fB::pdf4tcl::catPdf\fR \fIinfile\fR ?\fIinfile \&.\&.\&.\fR? \fIoutfile\fR
This call concatenates PDF files into one\&.
Currently the implementation limits the PDFs a lot since not all details
are taken care of yet\&. Straightforward ones like those created with pdf4tcl
or ps2pdf should work mostly ok\&.
.TP
\fB::pdf4tcl::getForms\fR \fIinfile\fR
This call extracts form data from a PDF file\&.
The return value is a dictionary with id/info pairs\&.
The id is the one set with \fI-id\fR to \fBaddForm\fR, if the PDF
was generated with pdf4tcl\&.
The info is a dictionary with the following fields:
.RS
.TP
\fBtype\fR
Field type\&.
.TP
\fBvalue\fR
Form value\&.
.TP
\fBflags\fR
Value of form flags field\&.
.TP
\fBdefault\fR
Default value, if any\&.
.RE
.PP
.SS "OBJECT COMMAND"
All commands created by \fB::pdf4tcl::new\fR have the following
general form and may be used to invoke various operations on their
pdf object\&.
.TP
\fBobjectName\fR \fBmethod\fR ?\fIarg arg \&.\&.\&.\fR?
The method \fBmethod\fR and its \fIarg\fR'uments determine the exact
behavior of the command\&. See section \fBOBJECT METHODS\fR for
the detailed specifications\&.
.PP
.SS "OBJECT METHODS"
.TP
\fIobjectName\fR \fBconfigure\fR
The method returns a list of all known options and their current
