Messing with the image functions
Hey everyone,
I'm trying to figure out the image functions in PHP and I wrote a script. It's supposed to load an image specified in the URL, store the color at every pixel in a variable, then echo it out as HTML. Just something odd I felt like wasting my time with. But it doesn't. It just loads forever.
Code:
<?php
if (!isset($pic)) $pic = 'default.jpg';
$im = imagecreatefromjpeg($pic);
if (!$im)
{
echo 'Error loading image!';
exit;
}
$crapol = getimagesize($pic);
$size[height] = $crapol[1];
$size[width] = $crapol[0];
$i = 1;
$i2= 1;
while ($size[height]>=$i)
{
if ($size[width]>=$i2)
{
$colorat[$i][$i2] = imagecolorat($im,$i,$i2);
$i2++;
}
else
{
$i++;
$i = 1;
}
}
$height='0';
$width='0';
while($height<=$size[height])
{
echo $colorat[$height][$width];
$colors = explode(\",\",$colorat[$height][$width]);
$red = $red+1;
$green = $green+1;
$blue = $blue+1;
$red2 = $red;
$green2 = $green;
$blue2 = $blue;
$r = '1';
$g = '1';
$b = '1';
$hexidecimals = '0,0,1,2,3,4,5,6,7,8,9,A,B,C,D,E,F';
$hex = explode(\",\",$hexidecimals);
while ($red2 > '16')
{
$red2 = $red2-16;
$r++;
}
while ($green2 > '16')
{
$green2 = $green2-16;
$g++;
}
while ($blue2 > '16')
{
$blue2 = $blue2-16;
$b++;
}
$colour[1] = $hex[$red2];
$colour[2] = $hex[$r];
$colour[3] = $hex[$green2];
$colour[4] = $hex[$g];
$colour[5] = $hex[$blue2];
$colour[6] = $hex[$b];
$haha = ''.$colour[1].$colour[2].$colour[3].$colour[4].$colour[5].$colour[6].'';
echo<<<MyDIV_
<div style='height: 1px; width: 1px; background-color: ; position: absolute; top: $height; left: $width;'>
</div>
MyDIV_;
if ($width<=$size[width])
{
$width++;
}
else
{
$height++;
$width='0';
}
}
?>I know it's not the BEST way to do it, but since it's just for my personall testing and crap I don't really care . Any help is greatly appreciated.
out,
necrotic
