No, if you read the help about [pix-data], you only need the range between 0 and 1 : The coordinates within the image (x-pos, y-pos) range from (0.0f, 0.0f) (left-bottom) to (1.0f, 1.0f) (right-top). So [gemmouse 1 1] is enough (on Linux you have to invert the values on Y axe). Your example is good for a square GEM window and return the position in its space (not in the pix 'space' of a picture). (I'm not sure to be clear here ?) Have a look at the attached patch. ++
