Library Output Map Thing to PGraphics Layer

Hi, I try to load shape files in a PGraphics layer. I used the mapthing library I have the problem, that I can't push the output of a library in the PGraphics buffer pg. It's always parented with the main sketch. Similar problem with the GeoMap, I posted here: https://forum.processing.org/two/discussion/26483/geomap-into-pgraphics#latest

Any Help very appriciated. Thanks Tom

BoundingBox envelope = new BoundingBox(4267, 90f, 180f, -90f, -180f);

Lines canals; PGraphics pg ;

public void setup() {

colorMode(HSB,360,100,100);

int d = 1200; size(2000,1000); pg= createGraphics(2000,1000);

smooth();

canals = new Lines(envelope, dataPath("shapes/Canals.shp"));

canals.setLocalSimplificationThreshold(0.1d);

}

public void draw() { background(0,0);

pg.beginDraw();

pg.strokeWeight(2.5f); pg.stroke(209,55,87,150); canals.project(this); //pg.canals.project(this) doesn't work.. pg.endDraw();

image(pg,0,0);
