Regarding flowing text around objects, do you have a function for breaking an arbitrary shape into a series of line rectangles that you'd be prepared to share with the world? http://www.cocoabuilder.com/archive/message/cocoa/2007/2/22/179186 ___ Cocoa

I don't think it makes the more classic approach wrong - it's just another way to crack that particular nut, with its own advantages (and probably disadvantages too, like more code, more dependency between classes, possibly lower performance, I don't know - but there's no "one true way" to

That is effectively what our renderer object does. Note that we transform the drawing space, not the object. For a group object, it sets the group's transform, then recursively calls the same rendering function for the objects in the group. Each object's transform is then applied within the

Hmmm... I'm just talking out loud here, but wouldn't it work to have a group model object whose drawing function is to concatenate its transform to the CTM then tell all the objects within the group to draw? Then all objects inside the group just do their drawing normally. -Kenny On May

This is a major advantage of separating the drawing (rendering) code from the data model instead of having objects draw themselves (not to mention cross-platform). Our renderer object is recursive (and could be a shared object if not for the deficiencies in shadow rendering -- a story for anot

Hi All, I want to do group rotation for various objects. Objects are getting rotate correctly on their center but when I group them the rotated object has got shift. Note: In case of group only rotated object has got shift. Below is the code snippet. Let me know I doing correct or not
