Hola tengo este codigo php para imprentar una marca de agua a la imagen generada pero no muestra la imagen tampoco pone la marca de agua gracias a los que me ayuden
Marca de agua Código PHP:
<?php
function watermark($SourceFile, $WatermarkFile, $SaveToFile = NULL)
{
$watermark = @imagecreatefrompng($WatermarkFile)
or exit('Cannot open the watermark file.');
imageAlphaBlending($watermark, false);
imageSaveAlpha($watermark, true);
$image_string = @file_get_contents($SourceFile)
or exit('Cannot open image file.');
$image = @imagecreatefromstring($image_string)
or exit('Not a valid image format.');
$imageWidth=imageSX($image);
$imageHeight=imageSY($image);
$watermarkWidth=imageSX($watermark);
$watermarkHeight=imageSY($watermark);
$coordinate_X = ( $imageWidth - 5) - ( $watermarkWidth);
$coordinate_Y = ( $imageHeight - 5) - ( $watermarkHeight);
imagecopy($image, $watermark, $coordinate_X, $coordinate_Y,
0, 0, $watermarkWidth, $watermarkHeight);
if(!($SaveToFile)) header('Content-Type: image/jpeg');
imagejpeg ($image, $SaveToFile, 100);
imagedestroy($image);
imagedestroy($watermark);
if(!($SaveToFile)) exit;
}
?>
El que genera la imagen Código PHP:
<?php
/* JPEGCam Test Script */
/* Receives JPEG webcam submission and saves to local file. */
/* Make sure your directory has permission to write files as your web server user! */
$filename = date('YmdHis') . '.jpg';
$result = file_put_contents( $filename, file_get_contents('php://input') ); if (!$result) {
print "ERROR: Failed to write data to $filename, check permissions\n";
exit(); }
// The image should be located in a non public directory
$result = file_put_contents( $filename, file_get_contents('php://input') );
// Locate the watermark file wherever you choose (remember PNG format
$watermark_location = 'watermark.png';
// Watermark the image and send it to the browser
watermark($result, $watermark_location, $result);
$url = 'http://' . $_SERVER['HTTP_HOST'] . dirname($_SERVER['REQUEST_URI']) . '/' . $filename;
print "$url\n";
?>
