Text within a PNG image

[MasterACE14]

Afternoon Everyone,

 

I have a script which basically puts in 2 words into a PNG image, what I want to do is, center the text horizontally, set the font to Arial, and make the text slightly transparent.

 

here is my script:

<?php

// variables
$testing = "Alpha Testing";

$image = "http://www.crikeygames.com.au/conflictingforces/images/conflicting_forces_header.png";  
$im = imagecreatefrompng($image); 
$wc = ImageColorAllocate ($im, 255, 255, 255);  
$red = ImageColorAllocate ($im, 255, 0, 0); 
ImageString($im, 3, 260, 2, $testing, $wc);  
header("Content-Type: image/png");  
Imagepng($im,'',100);  
ImageDestroy ($im); 

?>

 

any help is greatly appreciated

You will need to use getimagesize() to get the size of the image

Then use imagepstext() to place the text

 

You can subtract the pixels used in the text from the image width, divide that in half and use that as the starting point for the text.

that won't "center" it it will just put it int he middle, to "center it" you will need to find the length of it and the length of the string in pixels, then subtract the two and split the difference, however this should be already built.

$string = "Your Text Here";
$im     = imagecreatefrompng("bg.png");
$orange = imagecolorallocate($im, 0, 0, 0);
$px     = (imagesx($im) - 7.5 * strlen($string)) / 2;
imagestring($im, 3, $px, 9, $string, $orange);
imagepng($im);
imagedestroy($im);

 

I didn't really modify this code, but you should be able to, to get it to say what you want.  It centers the text.  It's also the wrong font.  I'm not sure how to change that.  Sorry.  Hope this helps a little.

I've now got it centered nicely, But I still don't know how to make it transparent(the string) and make it Arial font?

 

current code:

<?php

// variables
$testing = "Alpha Testing";

$image = "http://www.crikeygames.com.au/conflictingforces/images/conflicting_forces_header.png";  
$im = imagecreatefrompng($image); 
$wc = ImageColorAllocate ($im, 255, 255, 255);  
$red = ImageColorAllocate ($im, 255, 0, 0);
$px = (imagesx($im) - 7.5 * strlen($testing)) / 2;
ImageString($im, 3, $px, 16, $testing, $wc);  
header("Content-Type: image/png");  
Imagepng($im,'',100);  
ImageDestroy ($im); 

?>

If the text is always the same you could make an image that has transparency already and merge it onto the main image. Basically a watermark. You can google for php watermarks and find some good scripts already written.

Not sure if this helps or not. This means you will have to find the arial font file on your server and point to it.
