Image::Base::SVGout -- SVG image file output
use Image::Base::SVGout; my $image = Image::Base::SVGout->new (-width => 100, -height => 100); $image->set (-file => '/some/filename.svg'); $image->rectangle (0,0, 99,99, 'red'); $image->xy (20,20, '#FF00FF'); $image->line (50,50, 70,70, 'white'); $image->line (50,50, 70,70, 'green'); $image->save;
Image::Base::SVGout is a subclass of
Image::Base to write SVG format image files progressively.
This is an unusual
Image::Base module in that it writes to its
-file during drawing, rather than holding an image in memory. This means drawing operations are just prints of SVG elements to the file, but also means a
-file must be specified before drawing. The final
save() just writes a closing
</svg> to the file.
Image::Base functions are pixel oriented so aren't really the sort of thing SVG is meant for, but this module at least makes it possible to get some SVG out of
Image::Base style drawing code. SVG has many more features than can be accessed with the functions here, and it's just XML text so often isn't hard to spit out directly instead too.
Image::Base::SVG for similar SVG output but going to an
See "FUNCTIONS" in Image::Base for the behaviour common to all Image-Base classes.
$image = Image::Base::SVGout->new (key=>value,...)
Create and return a new SVGout image object.
$image = Image::Base::SVGout->new (-width => 200, -height => 100);
$newimage = $image->new (key=>value,...)
$image and apply the given settings. This can only be done before drawing has begun.
$colour = $image->xy ($x, $y)
Get an individual pixel. The return is always
undef since there's no support for picking out elements etc from the drawn SVG.
Loading is not possible with this module.
Save the image to an SVG file, either the current
-file option, or set that option to
$filename and save to there.
Set the SVG canvas size in pixels. These must be set before the first drawing operation, and cannot be changed after the first drawing operation (because they're printed in the initial SVG header).
