Candy: Draw svg on PGraphics
Feb 27^th, 2008, 4:12pm

Hi,

I am currently trying to draw an svg onto a PGraphics object.

I tried it like this:

import processing.candy.*;
import processing.xml.*;

PGraphics nimg;
SVG bot;

bot = new SVG(this, "cross.svg");

nimg = createGraphics(width, height, JAVA2D);
nimg.beginDraw();
nimg.bot.draw(0,0,100,100);
nimg.endDraw();

it tells me:
"no field named "bot" was found in type "processing.core.PGraphics""

Is there a simple way to get this to work?

Yeah. I kinda thought that there is no way right now.

Well since I dont really want to wait till a new release I will shortly tell what I am workin on:

The last 4 images on my flickr account are test renders of an algorithm i wrote inspired by mario klingemanns Image Foam thing he built in flash. I use the PGraphics buffer to draw new shapes on and compare its pixels[] with the pixels[] in the main buffer. Now that I cant use candy this way to load custom shapes id like to know if anyone has a different idea to get this to work with custom shapes!

It's a bit tricky, but you'll get what you want (your SVG) where you want (your custom PGraphics).

So you draw your svg on the screen. Copy it with get() and draw it on the PGraphic object and draw the PGraphic object on the screen.

I had another idea of making a rather big png of the svg and copy the png to the buffer to compare the pixels[] arrays. if they dont collide, i draw the svg at the same spot.
