Sometimes the pre-defined watermark positions are not enough and we may need custom positions, such as 25% below the middle center, etc.

I found this method but it seems protected.

Is there any way to programmatically set the position of a watermark? Such as by position of pixels from the top left of the image? For now I can set size and opacity of the watermark programmatically:

$this->helper('catalog/image')->init($_product, 'image')
    ->resize(600, null)

Wherein iGetWatermarkSize() is my in-house function that returns the size string for the watermark according to the width of the subject image.

I think it's sensible to have a method to set the position of a watermark in Magento but found nothing relevant in Google in this regard. Is there such a method or way for me to do this?

There is an public function Mage_Catalog_Helper_Image::watermark()

But you have to pass watermark image to this function as parameter.

 * Add watermark to image
 * size param in format 100x200
 * @param string $fileName
 * @param string $position
 * @param string $size
 * @param int $imageOpacity
 * @return Mage_Catalog_Helper_Image
public function watermark($fileName, $position, $size=null, $imageOpacity=null)
    return $this;
