Stupid image functions

Might as well post this question here as well… someone may learn something… I’m have a bit of trouble with the PHP image functions. The code is running correctly, but it doesnt’ show up as clearly as I would like it to…I’m trying to draw a J on the image. Here is the code:

<?
header("Content-type: image/jpeg");

$j_zero = array("1", "1", "1", "1", "1", "1", "1", "1", "1", "1");
$j_one = array("0", "0", "0", "0", "0", "0", "0", "0", "0", "1");
$j_two = array("0", "0", "0", "0", "0", "0", "0", "0", "0", "1");
$j_three = array("0", "0", "0", "0", "0", "0", "0", "0", "0", "1");
$j_four = array("0", "0", "0", "0", "0", "0", "0", "0", "0", "1");
$j_five = array("0", "0", "0", "0", "0", "0", "0", "0", "0", "1");
$j_six = array("1", "0", "0", "0", "0", "0", "0", "0", "0", "1");
$j_seven = array("1", "0", "0", "0", "0", "0", "0", "0", "0", "1");
$j_eight = array("1", "0", "0", "0", "0", "0", "0", "0", "0", "1");
$j_nine = array("0", "1", "1", "1", "1", "1", "1", "1", "1", "0");
$letterJ = array($j_zero, $j_one, $j_two, $j_three, $j_four, $j_five, $j_six, $j_seven, $j_eight, $j_nine);


$im = ImageCreate(100, 20);

ImageColorAllocate($im, 255,0,0);

$x_start = 20;
$y_start = 5;

for($i=0;$i<sizeof($letterJ);$i++)
{
	for($j=0;$j<sizeof($letterJ[0]);$j++)
	{
		if($letterJ[$i][$j] == 1)
		{
			ImageSetPixel($im, $x_start+$j, $y_start+$i, 255255255);
		}
	}
}




ImageJPEG($im);
ImageDestroy($im);
?>

but this is what it gets me: http://www.bluefinatlantic.com/egTest/imageFunc/random/random2.php

and thats not exactly clear now is it?

if you printscreen it and zoom-in in paintbrush, you’ll see that the lines that it’s drawing are 1px wide each… if you make them wider (double the 1’s in the array) it should be much clearer

actually I figured out the problem. It was becuase I was outputting as a jpg. A png, or a gif would be much clearer:) Now I just have to get my stupid function to work and I’ll be all set

lol… im very interested in seeing the results :beam:

here is what I have so far!

the code is here (but its messy):

Once I have more time to work on it, I will make the code better, shorter, and more efficient. But if you are interested then I might as well show you now

that’s awesome really… im impressed =)

system · June 27, 2003, 5:25am

I’m excited. This will end up being my footer but completely code generated and entirely random.

system · June 27, 2003, 5:32am

lol, now it should show up as random bgcolors…

system · June 27, 2003, 5:37am

awesome!

when i grow up, i wanna be just like you!

You gunna share the code? :chinaman:

system · June 28, 2003, 3:28am

no

yeah once I fix it up a bit. I started working on something else as well (can’t stay focused for too long on one thing…)
