The documentation of the watermark_size option for the /image/resize robot is not entirely clear to me. It states “Optional. The size in percent for this watermark. E.g. “50%”.”
What is this size measured against? What does 100%?
Say, my watermark-PNG is 200x100px and the image I’m resizing is 1200x900. Will setting the watermark_size = 50% result in a 100x50px watermark? And what if I resize the original image to 600x450? Will then watermark_size = 50% still result in a 100x50px watermark?
The reason I’m asking is: I want to supply a hi-res png as a watermark so it won’t look blurry even on the highest resolution images I want to store. But still I don’t want the watermark to be become to big.
How would you suggest to handle that? Maybe updating the documentation will just point me into the right direction…
