Is it possible to scale images inserted into the layout, short of saving the original file to a different resolution before using it with Therion?

Is it possible to put the image on the bottom layer, as it is with grids and surfaces?

Change its opacity?

(For example an indistinct image could be used as a watermark or background to the finished cave map drawing –not that I really want to do this, mainly just to get better control of the image)

layout

map-image 0 0 sw ./sketches/logo.jpg  /

#image bottom

#image-scale 2x /

#image-opacity 5  # in case the image is on top of the cave for instance

endlayout

Thanks

Bruce

PS: The continuous code grid works fine. Thanks Stacho
