Hello,

From the references above I was able to:
// https://processing.org/reference/PGraphics.html
// https://processing.org/reference/texture_.html
PGraphics pg;
PImage pi;
public void settings()
{
size(400, 400, P3D);
}
public void setup()
{
pg = createGraphics(100, 100);
pg.beginDraw();
pg.background(100);
pg.fill(255, 255, 0);
pg.textAlign(CENTER, CENTER);
pg.textSize(18);
pg.text("0", 0+10, 0+10);
pg.text("1", 100-10, 0+10);
pg.text("2", 100-10, 100-10);
pg.text("3", 0+10, 100-10);
pg.save("image.png");
pg.endDraw();
pi = loadImage("image.png");
}
public void draw()
{
image(pi, 200, 200);
noStroke();
beginShape();
textureMode(IMAGE);
texture(pi);
vertex(0, 0, 0, 0);
vertex(100, 0, 100, 0);
vertex(100, 100, 100, 100);
vertex(0, 100, 0, 100);
endShape();
