[RESOLVED] Layer rendering (image program)

[bergerkiller]

Note that there's also a Matrix.RotateAt(angle, point) which may save you having to do separate translations.

Yep I know. But I can't seem to get rotateat working. First to clear stuff up:
- layers can contain different types
- current type that is supported: "Picture Node"
- picture node arguments/paramters are:
+ location (as Watched point, structure I made myself to see if it has changed)
+ size (as Watched size)
+ static rotation (as Watched integer)
+ middle point for dynamic rotation (watched point)
+ dynamic rotation (variablehandler; changes value by setting a variable)
+ sizedimage property (checks for a changes size, generates a new sized image if needed)
+ color (new color class, capable of doing new stuff. Including: to image attributes, from/to ole; decimal text; drawing color; argb and "merge" option to merge it with other colors)

All key parts are now working, even the coloring.

As you saw in the draw sub, it takes a lot of stuff to draw the final image.
(that's why I used bitmaps to store them in the earlier version).

Now I have a couple of questions:
- how can I rotate the image around the middle using rotateat?
- how can I add "subclassing" so the subclasses can access the parent; for example:

public class testclass
   public b as integer
   sub new()
      me.testsubclass.a = 1
   end sub
   public class testsubclass
      public sub SetB()
         b = 2
      end sub
      public a as integer
   end class
end class

- How can I add additional effects to the graphics object (as example greyscale/inverted colors) If I need to apply it on every ondraw and not infront/after, how can I merge two effects?
