Re: Making Text [not the background] transparent

Graham:

Unless you need a specific font you could just do this by using pure CSS. If you do, the image layer would be behind the text layer. The text layer can be set to any color and (in most every modern browser) any alpha level. <div style="filter: alpha(opacity=90); opacity:0.9; background- color:transparent; color:#000;">This is some translucent text</div>

good luck!

How do I make the text transparent over the background ?

In my web app, I want to to put a layer BEHIND the image to control the color of the php-created text
So, the layer color in the web app shows thru the text php creates....
Would like to use  alpha transparency so the color looks clean :)

how would I amend the below script to do this ?

many thanks
g

header("Content-type:".$mime); //$mime = image/png
$im = imagecreatetruecolor(200, 16);  //use to draw a text box

imageAlphaBlending($im, true);
imageSaveAlpha($im, true);
$left    = 5; //add a little pad to the left edge
$color = imagecolorallocate($im, 255, 255, 255);
$fontSize = 11;

// choose a font
$fontPath = "/home/siren/fonts/";
$defaultFont = "tahomabd.ttf";
$fontName = "arial.ttf";
$font = $fontPath.$fontName ;
if (! file_exists($font)) {
   $font = $fontPath.$defaultFont ;
}

$text= "background color shows through the text" // Add the text
imagettftext($im, $fontSize, 0, 10, 13, $color, $font, $text);
imagepng($im);
readfile($im);
imagedestroy($im);
