[SOLVED] How to draw a thick arc (20 pixels)

[ExpertAlmost]

Good morning experts one and all!

 

I am trying to draw an arc 20 pixels wide. Unfortunately, imagearc() only draws a one pixel line while imagefilledarc() does not fill the arc to a specified depth (just various "pie" fillings).

 

So I tried a loop to draw 20 one-pixel lines. For some reason however, it appears that some pixels are dropped. This makes for a messy fill leaving black spots (or any background color) in the line. Attached is an example and the code is below.

 

What is the best way to draw a "thick" arc?

 

Thank you in advance for your kindness 

PS. How do you insert an image into messages on this board using the img tags?

[/img]

$img = imagecreatetruecolor(214, 345);
$white = imagecolorallocate($img, 255, 255, 255);
$red   = imagecolorallocate($img, 255,   0,   0);
for ($Cnt = 1; $Cnt <= 20; $Cnt++) {
$Measure = 300 + $Cnt;
imagearc($img, 20, 172, $Measure, $Measure, 315, 45, $red);
}

Humm

Well ImageSetThickness($img, 25); should do it but i think its a little buggy..

 

try saving as gif instead of png and use imagefilledarc twice, one with the foreground color then the background color

ie

<?php
header("Content-Type: image/gif");
$img = imagecreatetruecolor(350, 350);
$black = imagecolorallocate($img, 0, 0, 0);
$red   = imagecolorallocate($img, 255,   0,   0);
imagefill($img,0, 0,$black);
imagefilledarc($img, 70, 175, 300, 300, 315, 45, $red,IMG_COLOR_STYLEDBRUSHED);
imagefilledarc($img, 60, 175, 300, 300, 315, 45, $black,IMG_COLOR_STYLEDBRUSHED);
imagegif($img);
?>
