line()s in PDF have rounded corners no matter what
Aug 24th, 2009, 6:33pm  
Hello,

I've exported a chart to PDF and it looks ok except for lines drawn using the line() function. No matter what I tried, I couldn't get a nice sharp cap at the ends. I ended up using strokeCap(PROJECT) and noSmooth() and still they look rounded.

What am I doing wrong? I'm thinking of using very thin rect()s if I can't figure it out, but I know it's gonna bug me.

Works fine here.
just test this :

import processing.pdf.*;

void setup() {
 size(400, 400);
 noLoop();
 beginRecord(PDF, "filename.pdf");

}

void draw() {
 strokeWeight(10);
 line(150,150, width/2, height);
 strokeCap(SQUARE);
 line(100,100, width/2, height);

 endRecord();
}

if not, update to the latest processing version and try again.

Thanks Cedric! What I ended up doing was removing the strokeCap(PROJECT) in the setup() block and instead sticking a strokeCap(PROJECT) at the start of each function that involves drawing a line.
