this image marker!

[alwaysme]

hi i got to install a watermark mod...however the background is not transparent!

 

its always black and ugly...the file is a png transparent file...i tried with every transparent png i have and all the same result

 

this is the code

/ begin watermark mod

					$is_image = (strpos($filedata['mimetype'], 'image/') !== false) ? true : false;
					if ($is_image)
					{
						require("includes/watermark/phpWatermark-0.3/phpWatermark.inc.php");
						require("includes/watermark/config.php");
						$wm = new watermark("files/".$filedata['physical_filename']);
						$wm->setPosition($watermark['position']);
						if ($watermark['type'] == 'text')
						{
							if ($watermark['text_color'] != 'auto')
							{
								$wm->setFixedColor($watermark['text_color']);
							}
							$wm->addWatermark($watermark['text'], "TEXT");
						}
						elseif ($watermark['type'] == 'image')
						{
							$wm->addWatermark($watermark['image'], "IMAGE");
						}

						$im = $wm->getMarkedImage();
						imagepng($im, "files/".$filedata['physical_filename']);
					}

					// end watermark mod

 

 

is it possible that php is responsible for tranparentcy?

i find some code that i use to use on another script a long time ago....the watermark was an addon and it work really well....maybe we can use something from the code for the above to make it right??

 

$watermark_ok = 0;
if ($album_config['watermark_images'] == 1)
{
        $marktype = substr($album_config['watermark_source'], strlen($album_config['watermark_source']) - 4, 4);
        switch ( $marktype )
        {
                case '.png':
                        $nm = imagecreatefrompng($album_config['watermark_source']);
                        break;
                case '.gif':
                        $nm = imagecreatefromgif($album_config['watermark_source']);
                        break;
                case '.jpg':
                case 'jpeg':
                        $nm = imagecreatefromjpeg($album_config['watermark_source']);
                        break;
                default:
                        $nm = false;
        }

        if ( $nm )
        {
                $sx = imagesx($nm);
                $sy = imagesy($nm);

                switch ( $pic_filetype )
                {
                        case '.png':
                                $im = imagecreatefrompng(ALBUM_UPLOAD_PATH  . $thispic['pic_filename']);
                                break;
                        case '.gif':
                                $im = imagecreatefromgif(ALBUM_UPLOAD_PATH  . $thispic['pic_filename']);
                                break;
                        case '.jpg':
                        case 'jpeg':
                                $im = imagecreatefromjpeg(ALBUM_UPLOAD_PATH  . $thispic['pic_filename']);
                                break;
                        default:
                                $im = false;
                }

                if ( $im )
                {
                        $sx2 = imagesx($im);
                        $sy2 = imagesy($im);
                        imagecopymerge($im,$nm,($sx2 - $sx - 5), ($sy2 - $sy - 5), 0,0,$sx,$sy,40);

                        $watermark_ok = 1;
                }
        }
}

if ($watermark_ok)
{
        switch ( $pic_filetype )
        {
                case '.png':
                case '.gif':
                        header('Content-type: image/png');
                        imagepng($im);
                        break;
                default:
                        header('Content-type: image/jpeg');
                        imagejpeg($im);
                        break;
        }
}
