TYPO3 Core

Works for me using the patch in gerrit and the following code to watermark all images.

For an easier example just set XY to a fixed value and get rid of "10 = ..." completely. This way the watermark will be stretched depending on your image-size - but that's okay just for testing.

lib.watermark = IMG_RESOURCE
lib.watermark {
file = GIFBUILDER
file {
format = jpg
quality = 88

1. 10 is just used to detect the size
   10 = IMAGE
   10.file {
   import.current = 1
   treatIdAsReference = 1
   width.field = imagewidth
   maxW = {$styles.content.imgtext.maxW}
   maxW.override.data = register:maxImageWidth
   maxWInText = {$styles.content.imgtext.maxWInText}
   maxWInText.override.data = register:maxImageWidthInText
   }

15 = IMAGE
    15.offset = 10,10
    15.file = fileadmin/wasserzeichen.png
  }
}

tt_content.image.20.1.file {
m.mask.import.cObject < lib.watermark
m.mask.import.cObject.treatIdAsReference = 1
m.bgImg < .m.mask
}
