how can I see the picture in php.

[digitalroamer]

<?
$id = imagecreate(100,100);
$red = imagecolorallocate($id,255,0,0);
imagefill($id,0,0,$red);
imagewbmp($id);
imagedestroy($id);
?>

it seems the format doesn't match. But the gd version2 doesn't support gif any more. What should I do to see the picture? Thanks.

I'd just output a PNG or a JPEG.

But you need to have the script output an appropriate header. See the online manual entry for imagecreate() for an example.

With all that, just point your browser at the script.

oh, yes, you are right, I don't script a header since it always says a parse error when I write

header("Content-type : image/png");

is it because I configure wrong?

Thanks.

I don't know. What is the exact text of the error message?

You must have the GD library installed in order to make this work.

Check it out with

<?php
echo phpinfo();
?>

... look for the "gd" under "configuration". "GD support" must be enabled.

IF you have GD installed/enabled then have a go at this example
