Yes. Save a reference to the wordcram, and in your sketch's
mouseClicked events, ask the wordcram whether there's a word at the
mouse-click's coordinates. Something like this:
WordCram wordCram;
void setup() {
wordCram = new WordCram(this)...
wordCram.drawAll();
}
void mouseClicked() {
Word word = wordCram.getWordAt(mouseX, mouseY);
if (word != null) {
...
}
}For a complete running example sketch, check out File > Examples > Contributed Libraries > WordCram > tutorial > L_clickableWords.
Yes! It was added in the 0.5 release, and announced here.
To make a word cloud PDF, make your word cram sketch like you normally would, except:
- add
import processing.pdf.*;to the top - set up your sketch with
size(<yourWidth>, <yourHeight>, PDF, "path/to/your.pdf");
You can see a full example under File > Examples > Contributed Libraries > WordCram > OtherExamples > renderToPdf.
No, but I'm looking into it. It depends on whether javascript can "sense" the shape of the words to detect collisions. But it would be really cool to see word clouds in the browser.
If you know anything about turning fonts or words into something like a java.awt.Shape, let me know!
If you're loading your fonts with
loadFont, try using
createFont
instead. loadFont doesn't work as well for rendering characters at
different sizes.
Are you using something like Colorers.pickFrom(0) or
Colorers.pickFrom(255)? Try using Colorers.pickFrom(color(0)) and
Colorers.pickFrom(color(255)) instead.
Processing internally stores colors as
integers, with
the alpha in the highest bits, so it sees the integer 0 as colorless
and completely transparent. A WordCram created with
Colorers.pickFrom(0) will render the words, they'll just be
invisible.
Colorers.pickFrom() takes a bunch of colors, so it treats each
integer it gets as a Processing color/integer. This is really a
misleading API, and it should be sorted out.
Long story short: there probably isn't enough room to place all the words where you want them to go. Try making them smaller, or moving them around. You can read more about it on the blog.
