Name: SVG::GD
Version 0.20
Author: Ronan Oger
Abstract
Provide (as seamless as possible) an SVG wrapper to the GD API in order to provide SVG output of images generate with the Perl GD module
Synopsis
use GD;
use SVG::GD;
$im = new GD::Image(100,50);
# allocate black -- this will be our background
$black = $im->colorAllocate(0, 0, 0);
# allocate white
$white = $im->colorAllocate(255, 255, 255);
# allocate red
$red = $im->colorAllocate(255, 0, 0);
# allocate blue
$blue = $im->colorAllocate(0,0,255);
#Inscribe an ellipse in the image
$im->arc(50, 25, 98, 48, 0, 360, $white);
# Flood-fill the ellipse. Fill color is red, and will replace the
# black interior of the ellipse
$im->fill(50, 21, $red);
binmode STDOUT;
# print the image to stdout
print $im->png;gdTinyFont
returns SVG::GD::Font::Tiny
gdSmallFont
returns SVG::GD::Font::Small();
gdMediumBoldFont
returns SVG::GD::Font::Bold();
gdLargeFont
Returns SVG::GD::Font::Large()
gdGiantFont
Returns SVG::GD::Font::Giant()
gdBrushed
Does nothing at this time
getSVGstyle($font)
retrieve the style in SVG format for predefined fomts
setPixel
set a pixel to a colour Because SVG does not understand pixels, this method has to be faked. We know from the image size what is meant by a pixel, so we create a rectangle of size 1x1 and give it a colour
colorAllocate
Allocate the colour to a variable (red,green,blue)
colorResolve ($red,$green,$blue)
for an rbg tripplet, either returns the index for the colour or generates a new index for that colour
colorsTotal
return the number of allocated colors
colorExact
check for the existance of an exact color
colorClosest
returns the closest colour to the RGB triplet being submitted
line
Draw a line between 2 points
filledRectangle
Draw a filled rectangle.
rectangle
Draw a rectangle.
arc
Draw an arc. Only supports closed arcs at present. Note that we will ultimately need to differenciate between an arc and a circle.
SVG::GD::Image::filledPolygon
Draw a polygon defined by ab SVG::GD::Polygon object
polygon
Draw an empty polygon
string methods
string
write a text string
char
write a character
charUp
write a character upwards
rgb
Return the red,green,blue array for an allocated colour
svg
replace the gif writing request with an svg writing request
png
Return the binary image in PNG format
jpg
Return the binary image in JPEG format
gif
Return the binary image in GIF format Note that some versions of SVG::GD do not support this method
