Hi,

I’m trying to generate an SVG with bezier curves in it from processing. However, when I open the resulting SVG in illustrator, there are duplicates of every curve – one with no fill but a line, and one with no line, but a fill. I’m using the following settings:  
stroke(127,0,0);  
strokeWeight(3);  
noFill();

and creating the curve with a call to bezier()

Would appreciate help with this! Thanks

jen

Did you try 1 instead

Yes, the lines are still duplicated.

Here is a simple demo that has this bug:

```auto
import processing.svg.PGraphicsSVG;

PGraphics offscreenBuffer;

//===================================================
void setup() { 
  size(600,900);
  offscreenBuffer = createGraphics(width, height, SVG, "curveDemo.svg");
  offscreenBuffer.beginDraw();
}

//===================================================
void draw() {
  stroke(127, 0,0);
  strokeWeight(1);
  noFill();

  line(30,30,50,30);
  bezier(10, 20, 10, 10, 20, 20, 30, 30);
  offscreenBuffer.line(30,30,50,30);
  offscreenBuffer.bezier(10, 20, 10, 10, 20, 20, 30, 30);

}
 
 

//===================================================
void keyPressed() {
  switch (key) {
  case 's':
  case 'S': // S to save
    offscreenBuffer.dispose();
    offscreenBuffer.endDraw();
    offscreenBuffer = createGraphics(width, height, SVG, "curveDemo.svg");
    break;
  }

}
```

But when I change the code to create the buffer inside draw() things seem to work fine:

```auto
//===================================================
void draw() {
  stroke(127, 0,0);
  strokeWeight(1);
  noFill();

  line(30,30,50,30);
  bezier(10, 20, 10, 10, 20, 20, 30, 30);
  offscreenBuffer = createGraphics(width, height, SVG, "curveDemo.svg");
  offscreenBuffer.beginDraw();
  offscreenBuffer.strokeWeight(1);
  offscreenBuffer.noFill();
  offscreenBuffer.stroke(127,0,0);
  offscreenBuffer.line(30,30,50,30);
  offscreenBuffer.bezier(10, 20, 10, 10, 20, 20, 30, 30);
}

```
