GD Library help

[--ss--]

Well basically I've written the script below to connect to a SQL databse, retrieve a random name for it, with the name it gets an image from an external sites and overlays it ontop of a background then writes the name as a string onto the image and finally outputs it.

It was all working fine when all it had to do was get the image, I tried making it write the text but it messed up and now I keep getting errors :/

 

Any suggestions?

<?php
header("Content-type: image/gif");
//Info
$dbhost = "localhost";
$dbuser = "   ";
$dbpass = "   ";
$dbname = "   ";

//Connect
mysql_connect("$dbhost", "$dbuser", "$dbpass");
mysql_select_db("$dbname");

//Random Habbo
$random = mysql_query("SELECT name FROM names ORDER BY RAND() LIMIT 1");
$habbo = mysql_fetch_array($random);

//Generate Image
$text = $habbo[0];
$white = imagecolorallocate($im, 255, 255, 255);
$font = volter.ttf;
$im = imagecreatefromgif("bg.gif");
$in = imagecreatefromgif("http://www.habbo.co.uk/habbo-imaging/avatarimage?user=$habbo[0]&action=std&direction=4&head_direction=3&gesture=sml&size=l&img_format=gif");
$in_x = imagesx($in);
$in_y = imagesy($in);
imagecopymerge($im,$in,24,11,0,0,$in_x,$in_y,100);
imagettftext($im, 8, 0, 10, 20, $white, $font, $text);
imagegif($im);

imagedestroy($im);
?>

Btw, I know the database info is missing, that's cause I removed it myself.

 

Thanks for reading .

Bump :/

[MadTechie]

$in = imagecreatefromgif("http://www.habbo.co.uk/habbo-imaging/avatarimage?user=$habbo[0]&action=std&direction=4&head_direction=3&gesture=sml&size=l&img_format=gif");

 

should be

$in = imagecreatefromgif("http://www.habbo.co.uk/habbo-imaging/avatarimage?user=$text&action=std&direction=4&head_direction=3&gesture=sml&size=l&img_format=gif");

 

But without knowing the errors i can't say!

Technically it's just the same thing so it doesn't matter but thanks for pointing it out

 

Anyway the error I get is the normal GD Library error off:

The image “http://www.shanes.sawhosting.com/php/show.php” cannot be displayed, because it contains errors.

 

I beleive it has nothing to do with the actual two images merging and the first part and it's the text bit which is causing problematic as that's when the error started appearing .

change this

 

// $font = volter.ttf; // WRONG

$font = 'volter.ttf'; // Right

[--ss--]

change this

 

// $font = volter.ttf; // WRONG

$font = 'volter.ttf'; // Right

Haha should off known it'd be a noob error such as this >.< Thanks a ton!

 

Edit , Fixed it but it still doesn't work

imagecreatefromgif() takes a file name, not a URL.

I've used an almost identical script to this in the past where it did the same job of merging two images and it's always worked before though?

 

As I said , I believe that part is fine as it only started messing up when I tried adding text .

[BlueSkyIS]

ah, that's new info for me. thanks for that.

 

is your font file in the same directory as the script?

Indeed it is.

 

I'm not sure why this is happening now but when I remove the line to add text the script messed up (Even though it was fine before)

i get an error due to this being in the wrong place:

 

$white = imagecolorallocate($im, 255, 255, 255);

 

...should be after you define $im.

[BlueSkyIS]

i also had to put this before imagegif():

 

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

 

argh, never mind. i missed copying it from your first post.. still working onit.

[BlueSkyIS]

this works for me:

 

<?php
$habbo = "hello world";

//Generate Image
$text = $habbo;
$font = 'Andale Mono.ttf';
$im = imagecreatefromgif("coloradoflag.gif");
$white = imagecolorallocate($im, 255, 255, 255);
$in = imagecreatefromgif("http://www.habbo.co.uk/habbo-imaging/avatarimage?user=$habbo[0]&action=std&direction=4&head_direction=3&gesture=sml&size=l&img_format=gif");
$in_x = imagesx($in);
$in_y = imagesy($in);
imagecopymerge($im,$in,24,11,0,0,$in_x,$in_y,100);
imagettftext($im, 8, 0, 10, 20, $white, $font, $text);
header("Content-type: image/gif");
imagegif($im);

imagedestroy($im);
?>

 

note my changed font. i don't have the one you used.

Yay, now we're getting somewhere:

I know get this error instead:

Fatal error: Call to undefined function imagettftext() in /home/shanessa/public_html/php/show2.php on line 25

 

Line 25 being:

 imagettftext($im, 8, 0, 10, 20, $white, $font, $text);

 

Thanks for all your help so far!

bummer, it looks like you need to recompile PHP with missing truetype support using

 

--with-freetype-dir

AND

--enable-gd-native-ttf

 

http://us.php.net/imagettftext

I'm guessing my host doesn't have http://www.freetype.org/ installed?

Darn , is there a way off getting past this?
