Hi Roger, Could you use a vector graphic to show the scale of the image as it resizes? In this way, when the user stop resizing the graphic, set the rectangle of the image to the rect of the graphic. or... Do you had to show in real time the image change in size, as the user resizes the image? The stack "penToolv32c" have code to resize a vector graphic from a point the user clicked. It is in the stack with the Transformation tools: scale, rotate, skew and flip. Notice, this code uses matrices for resize calculations. You could download it from: <http://geocities.com/capellan2000/penToolv032c.zip> Have a nice weekend. al Visit my site: http://www.geocities.com/capellan2000/ ____________________________________________________ Start your day with Yahoo! - make it your home page http://www.yahoo.com/r/hs _______________________________________________ use-revolution mailing list use-revolution@lists.runrev.com Please visit this url to subscribe, unsubscribe and manage your subscription preferences: http://lists.runrev.com/mailman/listinfo/use-revolution
