ImageCreate problems

lokokolo

I am trying to use the imagecreate function to create a simple colored box. I think I have everything setup correctly, but I get two errors. The first one is a "Cannot add header info . . ." and the second one is the image stream is output in characters instead of an image, (e.g. ÿØÿàJFIFÿþ>CREATOR: gd-jpeg v1.0 (using IJG JPEG v62), default quality ÿÛC $.' ",#(7),01444'9=82<.342ÿÛC 2!!).

I am using WinXP and PHP 4.2.3. I have gd and zlib installed and enabled. I think it is just a simple thing, but I can't figure it out. Will someone please help this newbie? Here is my code:

<?
Header("Content-Type: image/jpeg");

$im = ImageCreate(500, 75);
$red = ImageColorAllocate($im, 255, 0, 0);
ImageFill($im, 100, 100, $red);
ImageJPEG($im);
?>

Thanks,

Works for me.

How are you calling it?

BTW I've noticed that the first allocated color is assumed to be the background color so you don't need the fill.

I call it by browsing to the page. for example, in my browser I'll type http://127.0.0.1/~/test.php and it spits out what I first posted.

Thanks,

loko,

Header functions MUST be called before anything else is output, therefore, if there is anything before it in your file that you didn't paste to us, it would throw that error. You may not even know there is whitespace before it. My suggestion is copy and paste it in notepad to a brand new .php file and upload it. The reason you are getting crappy output is because the header function isn't going through, so when you fix that the second problem will also be eliminated. Also, try using <?php instead of just <?.

Hope this helps,
Tom 🙂

Thank you TOM, That was it. I am using the coldfusion studio editor and it dumps a lot of base code (ie <html><head>, etc). Once I put it above this and took out any white space it worked.

Once again, Thank you!!
