Hey, I'm just started to study Java and Processing and have been playing around with loops, basic shapes, coordinates, maths etc, and have been to produce a simple drawing consisting of these principles. However i've made the screen size 300 by 300, after saving this, then trying to scale either in photoshop or in processing I lose some serious image quality. I''ve had a look at the scale(), resize() references and some tutorial pages but nothing seems to work for me :/  am I missing something simple?

Heres my code, its a recreation of a cross section of a pillar..

size(300, 300);                  //Creates a logo size of 300 px by 300 px
background(255);                   //Sets background colour to white
int o = 150;                       //Declares variable int o and assigns 150 to it, (origin)
smooth();                         //Smooths all lines to drawn from this point
ellipse(o, o, 220, 220);       //Creates a circle with diameter 220 px and origin at 150, 150
fill(100);                           //Sets fill to grey from this point on
ellipse(o, o, 180,180);        //Creates a circle with diameter 180 px and origin at 150, 150          
fill(255);                         //Sets fill to white from this point on
noStroke();                        //Removes Outline
for (float m = 0; m <=60; m = m + 2.5)      //Small circle positions
{                                
 double hAngle = 2.0 * Math.PI * m/60;
 double hX = o + 93 * Math.sin(hAngle);
 double hY = o - 93 * Math.cos(hAngle);
 float X = (float)hX;
 float Y = (float)hY;
 ellipse(X, Y, 22, 22);
}
noFill();                         //Removes fill
stroke(0);                        //Sets Outline to black

ellipse(o, o, 200, 200);      //Creates a circle with diameter 200 px and origin at 150, 150
ellipse(o, o, 180,180);       //Creates a circle with diameter 180 px and origin at 150, 150
ellipse(o, o, 270, 270);       //Creates a circle with diameter 270 px and origin at 150, 150
rectMode(CENTER);                 //Sets origin to center of square
rect(o, o, 270, 270);         //Creates a square with length 270 px and origin at 150, 150
rect(o, o, 275, 275);         //Creates a square with length 275 px and origin at 150, 150
for (float arC = 4.25; arC <=50; arC = arC + 15) //Creates 4 arcs for each corner

 float Start = (float)aAngle;
 float Stop = (float)aAngleStop;
 arc(o, o, 285, 285, Start, Stop );
}
line(211.35, 21.38, 278.62, 21.38);      //produces lines to connect the arcs.

Sorry its a bit messy!

Thanks,

Matt

ah seems like a simple solution! thanks i'll check it out
