Games::Go::Dg2Ps3pm

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.

Dg2Ps-specific options:

pageSize => 'page size'

May be one of:

'A0' - 'A9'

'B0' - 'B10'

'Executive'

'Folio'

'Half-Letter'

'Letter'

'US-Letter'

'Legal

'US-Legal'

'Tabloid'

'SuperB'

'Ledger'

'Comm #10 Envelope'

'Envelope-Monarch'

'Envelope-DL'

'Envelope-C5'

'EuroPostcard'

Default: 'Letter'

topMargin => points

bottomMargin => points

leftMargin => points

rightMargin => points

Margins are set in PostScript '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 stones and diagrams. Stone size is chosen 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).

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

ps_debug =#<gt> number from 0 to 2

When non-zero, code and subroutines are added to the PostScript output to help debug the PostScript file. This is very slightly documented in PostScript::File, but you'll probably need to read through the PostScript output to make any use of it.

Default: 0

$dg2ps->configure (option => value, ?...?)

Change Dg2Ps options from values passed at new time.

$dg2ps->print ($text ? , ... ?)

prints raw PostScript code to file as defined at new time.

$dg2ps->printComment ($text ? , ... ?)

Adds $text to the diagram comments.

$dg2ps->comment ($comment ? , ... ?)

Inserts the PostScript 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 = $dg2ps->convertDiagram ($diagram)

Converts a Games::Go::Diagram into PostScript.

my $converted_text = $dg2ps->convertText ($text)

Converts $text into text for display (handles PostScript escape sequences).

Returns the converted text.

$title = $dg2ps->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.

$dg2ps->close

prints final PostScript code to the output file and closes the file.
