Image creation

[steveangelis]

I am attempting to create an image and I have run into a snag.  I want to add both text and another image to the image I am making.  Here is the code so far minus unnecessary parts:

 

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

$name = $fetch_user['username'];

$rank = $fetch_rank['rank_title'];

$img_url = 'path''. $fetch_rank['rank_image'];

$im = @imagecreatefrompng("$img_url")

or die("Cannot Initialize new GD image stream");

// try changing this as well

$font = 4;

$width = imagefontwidth($font) * strlen($string) ;

$height = imagefontheight($font) ;

$im = imagecreatefrompng("image.png");

$x = imagesx($im) - $width ;

$y = imagesy($im) - $height;

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

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

//imagestring ($im, $font, $x, $y,  $string, $textColor);

imagestring ($im, $font, 100, 10,  $name, $textColor);

imagestring ($im, $font, 100, 22,  $rank, $textColor);

imagepng($im);

 

Everything works UNTIL I added in this part:

 

$im = @imagecreatefrompng("$img_url")

or die("Cannot Initialize new GD image stream");

 

Any idea what I am doing wrong? All that comes up is "Cannot Initialize new GD image stream"; and I know the URL's work.

I'm not sure it will make a difference, but you don't need the quotes surrounding the $img_url variable.

is the source image a png?

This has been tested and works.

Make appropriate modifications for your particular use.

<?PHP
header ("Content-type: image/png");
/* IMAGE TO USE AS BACKGROUND */
$source_image = "road000.png"; 

/* IMAGE TO OVERLAY ON BACKGROUND */
$overlay_image = "road001.png";

/* CREATE TEMPORARY BACKGROUND */
$background = imagecreatefrompng($source_image);

/* CREATE TEMPORARY OVERLAY IMAGE */
$insert = imagecreatefrompng($overlay_image); 

/* GET OVERLAY IMAGE WIDTH AND HEIGHT */
$insert_x = imagesx($insert); 
$insert_y = imagesy($insert); 

/* SET WHERE YOU WANT TO PLACE OVERLAY ON BACKGROUND */
/* FOR THIS EXAMPLE WE WILL USE 100 FROM LEFT AND TOP EDGES */
$set_x = 100;
$set_y = 100;

/* COMBINE THE IMAGES INTO A SINGLE OUTPUT IMAGE */
imagecopymerge($background,$insert,$set_x,$set_y,0,0,$insert_x,$insert_y,100); 

/* OUTPUT THE RESULTS */
imagepng($background); 

?>
