Games::Go::SGF2misc::SVG - Package to simplify SGF game rendering using Image::LibrSVG
use Games::Go::SGF2misc::SVG; my $image = new Games::Go::SGF2misc::SVG('imagesize' => '3in', 'boardsize' => 19, 'gobanColor'=> 'white' ); $image->drawGoban(); $image->placeStone('b','cd'); $image->placeStone('w',[4,2]); $image->placeStone('b','db'); $image->placeStone('w','dc'); $image->placeStone('b','cc'); $image->placeStone('w','eb'); $image->placeStone('b','cb'); $image->addCircle('cb',1); $image->save($filename); # As a .svg $image->export($filename); # As a .png
This module provides and SVG rendering backend for Games::Go::SVG2misc and other SGF parsers.
Games::Go::SGF2misc::SVG is a Perl Wrapper for the Image::LibRSVG.pm module. It simplifies the process of rendering an image from an SGF file. It is however still a primitive interface, in that it does not contain any internal intellegence about how to process an SGF file, this is merely designed to be used in conjunction with an SGF reader such as Games::Go::SGF2misc or Games::Go::SGF.
$image = Games::Go::SGF2misc::SVG-new(['imagesize' => 1in],['boardsize' => 19],['gobanColor' => 'white'])>
To create a new image, call the new() function. It's three arguments are optional, but if specified will override the defaults. B<imagesize> is the width and height of the image created and defaults to 2in if not specified. B<boardsize> is the number of lines horizontally and vertically across the board, with a default of 19. B<gobanColor>, b<whiteColor> and b<blackColor> are either an array of integers between 0 and 255, and SVG color keyword name, or an SVG hextriplet in the form #FFFFFF, much like html.
This command does all the initial setup of rendering the Goban. It sets the background color, and draws lines and star points. If you don't call this before any of the other drawing functions, you can expect your output to be a little weird.
This command puts a stone into the image at the position specified. B<$color> is one of /[BbWw]/ and controls whether a black or white stone is added. B<$position> is either an array of x,y coordinates with 0,0 in the upper left corner, or a string of letters representing coordinates at which the stone should be placed, in standard SGF format. 'aa' is the upper left corner, and 'ss' is the lower right (of a 19x19 game).
$image-addCircle($position)> $image-addSquare($position)> $image-addTriangle($position)>
This command adds either a circle, square or triange around the coordinates specified by B<$position>.
This command renders a letter above the coordinates specified by B<$position>. The processing performed is very similar to the other add* functions defined above.
Saves the in memory image into the filename specified in B<$filename>. The image will be saved as an uncompressed SVG file.
Exports the in memory image into the filename specified in B<$filename> as an image in PNG format.
$png = $image-dump($format)>
Converts the in memory image into an image of the format specified in B<$format>. If no format is specified the module defaults to SVG. The image is then returned to the calling function for storage. The possible formats are 'SVG', and 'PNG'. ** dump as PNG Not currently supported ** This function will be supported once it is supported by Image::LibRSVG which is, in turn, waiting for necessary support from gdk-pixbuf.
Presently the hoshi points are defined in a massive hash struct. I know the 19x19 hoshi's are correct but similarly I am sure that that rest are wrong, or simply not listed. Check with someone to find the correct hoshi points for oddball goban sizes.
