;original img: to-image layout [ backdrop black ; black will be keyed for transparency origin 0x0 H1 "hello there" white ] view center-face layout [image img] ; one way - make the face yourself rot-face: center-face make face [ image: img size: reverse img/size ; (width, height) -> (height, width) edge: none effect: [rotate 90] ; could put key black here too ] view rot-face ; or another way - lay it out with layout, and with transparency view center-face layout [ box red / 2 ; to make transparency obvious at 20x30 image img reverse img/size effect [rotate 270 key black] ] Anton.
