Watermarks are visible embedded overlay on a digital photo consisting of text, a logo, or a copyright notice that discourages others from taking your digital images and using them without your permission.
In the example below
this png image is used as a watermark for the iPhone photos.
To implement such a possibility, it is necessary to provide some event handlers. Technical details are as follows (click a link below to see the appropriate code):
function getImageWithWatermark($imagePath, $watermarkPath) {
list($sourceWidth, $sourceHeight) = getimagesize($imagePath);
$resultImage = imagecreatetruecolor($sourceWidth, $sourceHeight);
imagesavealpha($resultImage, true);
$background = imagecolorallocatealpha($resultImage, 0, 0, 0, 127);
imagefill($resultImage, 0, 0, $background);
$sourceImage = imagecreatefrompng($imagePath);
imagecopy($resultImage, $sourceImage, 0, 0, 0, 0, $sourceWidth, $sourceHeight);
$watermarkImage = imagecreatefrompng($watermarkPath);
imagecopy($resultImage, $watermarkImage, 0, 0, 0, 0, imagesx($watermarkImage), imagesy($watermarkImage));
ob_start();
imagepng($resultImage);
$imageData = ob_get_contents();
ob_end_clean();
return $imageData;
}
protected function doCustomRenderColumn($fieldName, $fieldData, $rowData, &$customText, &$handled)
{
if ($fieldName == 'photo_large' && !empty($fieldData)) {
$imagePath = sprintf('external_data/images/phone/iphone_large/%s', $fieldData);
if (FileUtils::FileExists($imagePath)) {
$watermarkPath = 'external_data/images/watermark.png';
$imageData = base64_encode(getImageWithWatermark($imagePath, $watermarkPath));
$src = 'data:image/png;base64,'.$imageData;
$customText = str_replace($imagePath, $src, $customText);
$handled = true;
}
}
}
