Hi

I'm using OpenGL for some particle animation - but the quads are showing a thin grey line around the edges.  The texture looks fine when the quad is the same size as the texture, but because I need multiple quad sizes ,the border lines show when smaller or larger.

Many thanks for any help,

Glenn.

8.   testpic=loadImage("testpic.jpg");

10.   noStroke();
11. }

13. void draw()
14. {
15.   background(255);
16. 
    
17.   scale(3.5);
18.   beginShape();
19.   texture(testpic);
20.   vertex(0, 0, 0, 0, 0);
21.   vertex(100, 0, 0, 300, 0);
22.   vertex(100, 100, 0, 300, 300);
23.   vertex(0, 100, 0, 0, 300);
24.   endShape();
