Hi, Because I had some requests to post the watermark script during the uploadprocess, here it is. This code works, untill the new version, 4.5, comes out - which has a watermark-option build in. ---------- You can put the folowing quote on top of your upload.php*-file I have commented out the logme function, as it is my own error-logger function. Code:function IUwatermark($TheSourceFile, $TheWatermarkFile, $SaveToFile = NULL) {
/* Image */
$waterimage = @imagecreatefrompng($TheWatermarkFile); // or logme('w00t! Error!'); /* My LOGGER. Commented for Forum */
imageAlphaBlending($waterimage, false);
imageSaveAlpha($waterimage, true);
/* Get image info */
$image_string = @file_get_contents($TheSourceFile); // or logme('Imagefile error: Unable to open');
$image = @imagecreatefromstring($image_string); // or logme('Unknown format');
$imageWidth=imageSX($image);
$imageHeight=imageSY($image);
/* Set image info */
$watermarkWidth=imageSX($waterimage);
$watermarkHeight=imageSY($waterimage);
/* Where will the image be? */
/* Mine: bottomright */
$coordinate_X = ( $imageWidth - 5) - ( $watermarkWidth);
$coordinate_Y = ( $imageHeight - 5) - ( $watermarkHeight);
imagecopy($image, $waterimage, $coordinate_X, $coordinate_Y,
0, 0, $watermarkWidth, $watermarkHeight);
/* Output */
if(!($SaveToFile)) header('Content-Type: image/jpeg');
imagejpeg ($image, $SaveToFile, 100);
imagedestroy($image);
imagedestroy($waterimage);
if(!($SaveToFile)) exit;
}
The next part is to call the function. Now, I did it in, maybe a weird, way. But hey, it still won't affect the uploadprocess-time ;) First, I will let the ImageUploader, upload the file. (you can find the meaning of $fileNameEcht here. It's the function which creates random keynames.) Code:
... while the image is uploading, i give it a new filename
... so this is all before the watermark-process
$fileNameEcht = generateKey(8);
... below, is after the image has been uploaded
$image_location = "FakeDirectory/FakeImages/". $fileNameEcht .".jpg";
$watermark_location = 'myWatermarkImage.png'; // should be in your upload-directory
$save_watermarked_file_to = "FakeDirectory/FakeImages/". $fileNameEcht .".jpg";
Now, to call the function: Code:IUwatermark($image_location, $watermark_location, $save_watermarked_file_to);
I am very very sorry for the: 1) bad English 2) bad Code (-markup) 3) bad 'manual' If anyone wants to edit the post, feel free to do it. I just created this post, because of the requests I received. Again, sorry. But, if you need any help, suggestions or anything else.. .. I will try to explain the best I can! Kinds regards, - Frank Weima Edited by user Tuesday, December 18, 2007 3:32:43 AM(UTC)
