getChild() not displaying anything

Processing Coding Questions

import processing.svg.*;
PShape s;
float reso, dLen;
int counter = 0;
void setup() {
  size(800, 800); 
  reso = width;
  dLen =sqrt(pow(reso, 2)+pow(reso, 2));
  shapeMode(CENTER);
  beginRecord(SVG, "DL-"+nf(counter, 3)+".svg");
}

void draw() {
  translate(width/2,height/2);
  PShape s0 = createShape(GROUP);
  s0.addChild(bgdRect());

  float xoff = reso/2 + 30;
  float yoff = dLen/2 - 05;
  PShape s = createShape();
  s.beginShape();
  s.fill(255);
  s.stroke(255);
  s.vertex(-xoff, 0);
  s.vertex(0, -yoff);
  s.vertex(xoff, 0);
  s.vertex(0, yoff);
  s.endShape(CLOSE); 

  s0.addChild(s);
  shape(s0,0,0);
  endRecord();
  
}

PShape bgdRect() {
    PShape rect = createShape(RECT, -width/2, -height/2, width, height);
    rect.setFill(0);
    return rect;
  }

Code above is for creating svg.

PShape s;
PShape s1 ;
void setup() {
  size(800, 800);
  //background(127);
  s = loadShape("DL-000.svg");
  shapeMode(CENTER);
  s1= s.getChild(0);
  println(s.getChildCount());
}

void draw() { 
  translate(width/4,height/4);
  shape(s, 0, 0, 300, 300);
  translate(width/2,height/2);
  shape(s1, 0, 0, 300, 300);
}

The above code displays svg as whole but not when one of the shape is extracted using getChild.
I don’t know why getchild is not working.

I think you should do something like :

PShape[] shapes;
shapes = s.getChildren(); // in setup()
shape(shapes[0], 0, 0, 300, 300); // in draw()
3

Still doesn’t work. Same result

4

It’s maybe the way your origin file is written. Try to open another svg file, open a text editor and search the difference.

5

Other example svgs getChild works so the issue is with the svg coding. I drew the shapes without using Pshape and recorded the svg but same result. The code is simple,can’t figure out the issue.

Show us a part of your svg file with headers

// Creating SVG using PShape

import processing.svg.*;
PShape s;
float reso, dLen;
int counter = 0;
PShape s0; 

void setup() {
  size(800, 800);
  noLoop();
  reso = width;
  dLen =sqrt(pow(reso, 2)+pow(reso, 2)); // Diagonal Length 
  
  // Creating group shape to add shapes
  s0 = createShape(GROUP); 
  
  //Creating & Adding first shape Rectangle
  s0.addChild(bgdRect());
  
  // Creating & Adding second shape Rhombus
  s = createShape();
  float xoff = reso/2 + 30;
  float yoff = dLen/2 - 05;
  pushMatrix();  
  s.beginShape();
  s.fill(255);
  s.stroke(255);
  s.vertex(-xoff, 0);
  s.vertex(0, -yoff);
  s.vertex(xoff, 0);
  s.vertex(0, yoff);
  s.endShape(CLOSE); 
  popMatrix();  
  s0.addChild(s);
    
  beginRecord(SVG, "DL-"+nf(counter, 3)+".svg");
}

void draw() {  
  translate(width/2, height/2);  
  shape(s0,0,0);
  endRecord(); 
}

PShape bgdRect() {
  PShape rect = createShape(RECT, -width/2, -height/2, width, height);
  rect.setFill(0);
  return rect;
}


// Creating SVG without using PShape, directly drawing the shapes 

import processing.svg.*;
float reso, dLen;
int counter = 0;

void setup() {
  size(800, 800);
  noLoop();
  reso = width;
  dLen =sqrt(pow(reso, 2)+pow(reso, 2)); // Diagonal Length 
  
  beginRecord(SVG, "DL-"+nf(counter, 3)+".svg");
}

void draw() {  
  pushMatrix();  
  translate(width/2, height/2); 
  
  // Drawing first shape Rectangle
  bgdRect();
  
  // Drawing second shape Rhombus
  float xoff = reso/2 + 30;
  float yoff = dLen/2 - 05;  
  beginShape();
  fill(255);
  stroke(255);
  vertex(-xoff, 0);
  vertex(0, -yoff);
  vertex(xoff, 0);
  vertex(0, yoff);
  endShape(CLOSE); 
  popMatrix();  
  endRecord(); 
}

void bgdRect() {
  fill(0);
  stroke(0);
  rectMode(CENTER);
  rect(0,0,width,height);
}

I figured out that the getChild() only works with name and not index in processing. removeChild() works with both index and name. So for getChild() to work, shapes have to be named manually.
