NAME
Games::Go::Dg2PDF - Perl extension to convert Games::Go::Diagrams to PDF (Portable Document Format).SYNOPSIS
use Games::Go::Dg2PDFmy $dg2pdf = B<Games::Go::Dg2PDF-E<gt>new> (options); $dg2pdf->convertDiagram($diagram);
DESCRIPTION
A Games::Go::Dg2PDF object converts a Games::Go::Diagram object into a PDF file.METHODS
- my $dg2pdf = Games::Go::Dg2PDF->new (?options?)
- A new Games::Go::Dg2PDF takes the following options:
General Dg2 Converter Options:
- boardSize => number
- Sets the size of the board.
Default: 19
- doubleDigits => true | false
- Numbers on stones are wrapped back to 1 after they reach 100. Numbers associated with comments and diagram titles are not affected.
Default: false
- coords => true | false
- Generates a coordinate grid.
Default: false
- topLine => number (Default: 1)
- bottomLine => number (Default: 19)
- leftLine => number (Default: 1)
- rightLine => number (Default: 19)
- The edges of the board that should be displayed. Any portion of the board that extends beyond these numbers is not included in the output.
- diaCoords => sub { # convert $x, $y to Diagram coordinates }
- This callback defines a subroutine to convert coordinates from $x, $y to whatever coordinates are used in the Games::Go::Diagram object. The default diaCoords converts 1-based $x, $y to the same coordinates used in SGF format files. You only need to define this if you're using a different coordinate system in the Diagram.
Default:
sub { my ($x, $y) = @_;
$x = chr($x - 1 + ord('a')); # convert 1 to 'a', etc
$y = chr($y - 1 + ord('a'));
return(``$x$y''); }, # concatenate two letters - print => sub { my ($dg2tex, @tex) = @_; ... }
- A user defined subroutine to replace the default printing method. This callback is called from the print method (below) with the reference to the Dg2TeX object and a list of lines that are part of the TeX diagram source.
Dg2PDF-specific options:
- pageSize => 'page size'
- May be one of:
-
- a0 - a6
- letter
- broadsheet
- ledger
- tabloid
- legal
- executive
- 36x36
Default: 'letter'
-
- topMargin => points
- bottomMargin => points
- leftMargin => points
- rightMargin => points
- Margins are set in PDF 'user space units' which are approximately equivilent to points (1/72 of an inch).
Default for all margins: 72 * .70 (7/10s of an inch)
- text_fontName => 'font' Default: 'Times-Roman',
- stone_fontName => 'font' Default: 'Courier-Bold'
- Text and stone fonts names may be one of these (case sensitive):
-
- Courier
- Courier-Bold
- Courier-BoldOblique
- Courier-Oblique
- Helvetica
- Helvetica-Bold
- Helvetica-BoldOblique
- Helvetica-Oblique
- Times-Roman
- Times-Bold
- Times-Italic
- Times-BoldItalic
-
- text_fontSize => points
- The point size for the comment text. Diagram titles use this size plus 4, and the game title uses this size plus 6.
Default: 11
- stone_fontSize => points
- The stone_fontSize determines the size of the text inside stones, and may also determine the size of the stones and diagrams (see stone_height and stone_width below).
Default: 5
- stone_width => points
- stone_height => points
- The stone_width and stone_height determine the size of the stones and diagrams.
If stone_width is not explicitly set, it is calculated from the stone_fontSize to allow up to three digits on a stone . The default stone_fontSize allows for three diagrams (with -coords) per 'letter' page if comments don't take up extra space below diagrams. If doubleDigits is specified, the stones and board are slightly smaller (stone 100 may look a bit cramped).
If stone_height is not explicitly set, it will be 1.05 * stone_width, creating a slightly rectangular diagram.
Default: undef - determined from stone_fontSize
- $dg2pdf->configure (option => value, ?...?)
- Change Dg2PDF options from values passed at new time.
- $dg2pdf->print ($text ? , ... ?)
- prints raw PDF code to file as defined at new time. Whether or not file was defined, print accumulates the PDF code for later retrieval with converted.
- $dg2pdf->printComment ($text ? , ... ?)
- Adds $text to the diagram comments.
- $dg2pdf->comment ($comment ? , ... ?)
- Inserts the PDF comment character ('%') in front of each line of each comment and prints it to file.
Note that this is not the same as the printComment method.
- my $canvas = $dg2pdf->convertDiagram ($diagram)
- Converts a Games::Go::Diagram into PDF.
- my $converted_text = $dg2pdf->convertText ($text)
- Converts $text into text for display - gee, that's not very hard. In fact, this method simply returns whatever is passed to it. This is really just a place-holder for more complicated converters.
Returns the converted text.
- $title = $dg2pdf->convertProperties (\%sgfHash)
- convertProperties takes a reference to a hash of properties as extracted from an SGF file. Each hash key is a property ID and the hash value is a reference to an array of property values: $hash->{propertyId}->[values]. The following SGF properties are recognized:
-
- GN GameName
- EV EVent
- RO ROund
- PW PlayerWhite
- WR WhiteRank
- PB PlayerBlack
- BR BlackRank
- DT DaTe
- PC PlaCe
- GC GameComment
- KM KoMi
- RE REsult
- TM TiMe
Both long and short property names are recognized, and all unrecognized properties are ignored with no warnings. Note that these properties are all intended as game-level notations.
-
- $dg2pdf->close
- prints some final PDF code to the diagram and closes the pdf object (file).
