Processing Coding Questions
1

Im fairly new to processing. Im using PGraphics to try a simple paint program.
but I want my program to be primitive looking ( low resolution ), I’ve managed to get it in fullscreen with a custom low-res resolution, but my strokes look weird and outlined. I really just want a sharp, pixelated look. I haven’t been able to find any resources for creating a pixelated look.

heres my code: ( note please change the variables displayW && displayH to your correct screen resolution)

PGraphics layer0;
int pgWidth = 128;
int pgHeight = 72;
float displayW=2560;
float displayH=1600;

color var_brushColor = color(255, 255, 0);
int mousePress=0;

void setup()
{
  fullScreen(P2D, 1);
  background(255, 255, 255);
  layer0 = createGraphics(pgWidth, pgHeight);//, P2D);
}

void draw() {

  // quick test to change colors
  if (keyPressed)
  {
    if (key == 'Q' || key == 'q')
    {
      var_brushColor= color(255, 0, 0);
    }

    if (key == 'W' || key == 'w') 
    {
      var_brushColor= color(0, 255, 0);
    }
  }

  // custom mouse variables
  float mouse_x=((mouseX+mouseX)/(displayW/(pgWidth)));
  float mouse_y=((mouseY+mouseY)/(displayH/(pgHeight)));
  float pMouse_x=((pmouseX+pmouseX)/(displayW/(pgWidth)));
  float pMouse_y=((pmouseY+pmouseY)/(displayH/(pgHeight)));

  layer0.beginDraw();

  if (mousePress==1)
  {
    layer0.stroke(var_brushColor);
    layer0.strokeWeight(0);
    layer0.line(mouse_x, mouse_y, pMouse_x, pMouse_y);
  }

  layer0.endDraw();
  image(layer0, 0, 0, width, height);
}

void mouseDragged()
{ 
  mousePress=1;
} 
void mouseReleased() { 
  mousePress=0;
}

Hi,

Is it what you are looking for ?

void setup()
{
  fullScreen();
  smooth(0);
  background(255, 255, 255);
  layer0 = createGraphics(pgWidth, pgHeight);//, P2D);
  println(pgWidth, pgHeight);
}
