I have an issue like this.

I inserted a rectangle to the document, and create a bitmap in memory with exact width and height of the shapes bounds. (It is as same as if i ad a polygon)

Set fill style to imagefillstyle and set the newly created bitmap as fill image. When the shapes bounds changes, i catch it from event sink service and works greate. On every bound change event, i create e new bitmap with the size of shapes bounds. The MapLayout = MapLayout.Centered. When i resize the shape from GeometryPoints, everything is ok, but when i resize the shape from Bounds Control Points, the image scales and gets bigger (Although a new image with the new size is created) (likely shape zooms to the image)

Why may this happen. Wneh i debug i saw that on every size change correct size of image is created in memory and that image is set as background image of shape. How can i prevent shape scales the image?

Thanks for further help
