ImageColorTransparent

[sachinphp]

I'm trying to really simple things with ImageColorTransaprent:

---

// send header

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

// create image and colours

$im = ImageCreate(150, 15);

$red = ImageColorAllocate($im, 255, 0, 0);
$black = ImageColorAllocate($im, 0, 0, 0);
$white = ImageColorAllocate($im, 255, 255, 255);
$blue = ImageColorAllocate($im, 0, 0, 255);

$trans=ImageColorTransparent($im,$blue);

ImageFill($im,0,0,$trans);
// write string at (0,0) in white
ImageString($im, 2, 0, 0, "hello", $white);

// release image
ImageJPEG($im);

---

I get a really weird set of blobs when the browser opens up the dynamic gif in PhotoEditor. Anyone have an idea?

Cheers
