When I call it (get-bounding-rect "Some #\Newline text" "arial" 50) I get an error:

Type-error in KERNEL::OBJECT-NOT-TYPE-ERROR-HANDLER:

Ah, yes, there was a bug in there. Thanks for the report. The new release should fix that.

(defun get-bounding-rect (text font font-size) (with-image* (0 0) (let ((rect (draw-freetype-string 0 0 text :do-not-draw t :font-name font :angle 0 :line-spacing 1.05d0 :color (find-color 0 0 255 :resolve t) :point-size font-size))) (values (- (aref rect 2) (aref rect 0)) (- (aref rect 3) (aref rect 5)) (aref rect 0) (aref rect 1) rect))))

Here's an easier version: (defun get-bounding-rect (text font font-size) (let ((rect (draw-freetype-string 0 0 text :do-not-draw t :font-name font :line-spacing 1.05d0 :point-size font-size))) (values (- (aref rect 2) (aref rect 0)) (- (aref rect 3) (aref rect 5)) (aref rect 0) (aref rect 1) rect)))

I think it doesn't like my :line-spacing 1.05d0 parameter.

That wasn't really the problem (but it showed the symptoms).

Also I am not sure that I can provide a string with #Newline.

You can't do it the way you did. There are basically two easy ways to do it in portable Common Lisp. Number one: (get-bounding-rect "Some text" "arial" 50) Number two: (get-bounding-rect #.(format nil "Some~%text") "arial" 50) Or use CL-INTERPOL: (get-bounding-rect #?"Some\ntext" "arial" 50) Cheers, Edi. _______________________________________________ cl-gd-announce mailing list cl-gd-announce@common-lisp.net http://common-lisp.net/cgi-bin/mailman/listinfo/cl-gd-announce _______________________________________________ announcements site list announcements@common-lisp.net http://common-lisp.net/mailman/listinfo/announcements
