load PShape from String, instead of URI

[processing-bugs]

Original author: niho...@gmail.com (June 23, 2010 19:41:09)

It would be extremely useful if there was a way to construct a PShape from a valid SVG string, rather than from URI, because this would make it possible to have write Processing code that dynamically generates a legal SVG string and then turn it into a PShape for use in the sketch.

Since this functionality is technically already in the code (because PShape has to call the string-parsing methods after it resolves the svg URI), could it be made public?

Might I request something like:

String svg = "<svg ...><path d='...'/>...</svg>";
PShape s = loadShapeFromString(svg);
shape(s, 0, 0, 50, 50);

We try to avoid lots of top-level API like that, but in the meantime you can use:

loadShape(new XMLElement(svg))

...which is about as many characters as loadShapeFromString(svg).

Nice, although then it might be a good idea to add a bit to the documentation to say that loadShape() can also take an XMLElement as constructor argument, rather than only the URI string that is listed now.

I tried the following in Processing 1.2 but it does not work:

XMLElement x = new XMLElement("");
s = loadShape(x);

it cites the error "method loadShape(String) in PApplet is not applicable to arguments (XMLElement)", so it would look like either this functionality got removed (which would be horrible!) or it was never there (equally horrible!).

Can I reopen the request for building a PShape from an SVG string in some manner? I like the idea of doing it via XMLElement, so if that can be made to work, all the better.

PShape s = new PShapeSVG(new XMLElement("..."));

Update on this ticket due to #608: the XMLElement constructor constructs an empty XML element with the passed string as full name, rather than parsing it as XML. In order to build an XMLElement from an XML string, the following should be used instead:

PShape s = new PShapeSVG(XMLElement.parse("..."));

(note that the old approach is valid up to and including 1.2.1 - the new approach is valid as (at least) prerelease 0194)

Closing this issue; for 2.0, we've decided it'll remain essentially the method seen in comment #7, though XMLElement will have a new name.
