Hi,
I am having PHP Version 4.3.4 with GD 2.0.15 compatible and PNG support
enabled.
My problem with the following code is that the image produced be this code
is not transparent. It has a black background. I have viewed it in IE 6 and
its not transparent.
Can someone help me how to make this image transparent?
<?php
// imagecolorallocate ( resource image, int red, int green, int blue)
// imagettftext ( resource image, float size, float angle, int x, int y, int
color, string fontfile, string text)
// imagepng ( resource image [, string filename])
// imagecreatetruecolor ( int x_size, int y_size)
// imagecolortransparent ( resource image [, int color])
header("Content-type: image/png");
$im = imagecreatetruecolor(400,600); // i have used imagecreatetruecolor in
place of imagecreate()
$bg = imagecolorallocate($im, 0, 0, 0);
imagecolortransparent($im, $bg); // this function makes the color
transparent specified in $bg.
$j=0;
$k = 0;
$r = 1;
$g = 100;
$b = 20;
for($i=1;$i<=50;$i++)
{
if($r > 255)
$r = 1;
if($g > 255)
$g = 100;
if($b > 255)
$b = 20;
$textcolor = imagecolorallocate($im, $r, $g, $b);
$r = $r * 3;
$g = $g + 10;
$b = $b + 20;
imagettftext($im, 10, 0, 0, $j, $textcolor, "fonts/2.ttf", "Row number
: $i | Color = " . $textcolor);
$j=$j+12;
}
imagepng($im,"kk.png");
?>
Thanks a lot for reading this far.
