Hi all,
Sorry for this stupid question, but I am having trouble mixing imagecopy
etc. with HTML.
What I am trying to do is copy an image, and then obtain co-ordinates from a
database which will then be drawn
on the image (to create a clickable imagemap). The image will then be
displayed as part of a webpage.
I've included my code snippet below. It doesn't work, and I think I know
why - the output on my screen
grumbles about the header information already being sent. Is there any way
to do what I want it do?
Perhaps putting the image copy calls in a separate function call?
Sorry for the stupid question, I am new to php.
Best wishes
Paul
<HTML>
<H1>Test...</H1>
<?php
// File and new size
$filename = 'logo_i.JPG';
// Content type
header('Content-type: image/jpeg');
// Get new sizes
list($width, $height) = getimagesize($filename);
// Load
$thumb = imagecreatetruecolor($width, $height);
$source = imagecreatefromjpeg($filename);
// Resize
imagecopy($thumb, $source, 0, 0, 0, 0, $width, $height);
imagerectangle($thumb, 10,10,50,50,4500);
// Output
imagejpeg($thumb);
?>
</HTML>
