Url den resim çekip filigran basma

09-12-2010, 13:52:43

Aşağıdaki kodu internetten buldum çokta güzel çalışıyor ve kendime göre düzenledim. Ancak bilgisayarımdaki bir dosyayı upload edersem çalışıyor. Ben herhangi bir url girdiğimde onu ftpye çekmesini ve daha sonra işlem yapmasını istiyorum. Sizce bu mümkün müdür?

index.html

Resim yükle

<form action="watermark.php" method="post" enctype="multipart/form-data">

<input type="file" name="File1" ><br>
<input type="submit" value="Resmi Yükle">
</form>

watermark.php

<?php

define( 'WATERMARK_OVERLAY_IMAGE', 'serpito.png' ); // Resim uzerine basilacak logo
define( 'WATERMARK_OVERLAY_OPACITY', 50 ); //Opacity - seffaflik
define( 'WATERMARK_OUTPUT_QUALITY', 90 ); // Resim kalitesi

function create_watermark( $source_file_path, $output_file_path )
{
list( $source_width, $source_height, $source_type ) = getimagesize( $source_file_path );

if ( $source_type === NULL )
{
return false;
}

switch ( $source_type )
{
case IMAGETYPE_GIF:
$source_gd_image = imagecreatefromgif( $source_file_path );
break;
case IMAGETYPE_JPEG:
$source_gd_image = imagecreatefromjpeg( $source_file_path );
break;
case IMAGETYPE_PNG:
$source_gd_image = imagecreatefrompng( $source_file_path );
break;
default:
return false;
}

$overlay_gd_image = imagecreatefrompng( WATERMARK_OVERLAY_IMAGE );
$overlay_width = imagesx( $overlay_gd_image );
$overlay_height = imagesy( $overlay_gd_image );

imagecopymerge(
$source_gd_image,
$overlay_gd_image,
$source_width - $overlay_width,
$source_height - $overlay_height,
0,
0,
$overlay_width,
$overlay_height,
WATERMARK_OVERLAY_OPACITY

imagejpeg( $source_gd_image, $output_file_path, WATERMARK_OUTPUT_QUALITY );

imagedestroy( $source_gd_image );
