;;; Commentary:

;;; These are several utlity functions for canvas operations that can
;;; be implemented in Lisp code.

\f
;;; Code:

(defun canvas-fill-pixel (canvas x y color opacity)
  "Set the pixel at X, Y inside CANVAS to COLOR, with the opacity OPACITY."
  (canvas-rectangle canvas x y 1 1 color opacity))

(defun canvas-from-image (image &optional width height)
  "Create a canvas from IMAGE.
The canvas will be no wider than WIDTH (if specified),
and no taller than HEIGHT (if specified)."
  (let ((canvas (make-canvas (or width (car (image-size image t)))
                             (or height (cdr (image-size image t))))))
    (prog1 canvas (canvas-draw-image canvas image 0 0))))

(defun canvas-width (canvas)
  "Return the width of CANVAS."
  (car (canvas-dimensions canvas)))

(defun canvas-height (canvas)
  "Return the height of CANVAS."
  (cdr (canvas-dimensions canvas)))

(provide 'canvas)
