image - WPF ZoomControl and Adorners -


this first post on stack overflow, hope right. using zoomcontrol wpf extensions display image pan , zoom support:

<dockpanel grid.row="1" x:name="canvas">                  <controls:zoomcontrol  x:name="zoomcontrol">           <canvas x:name="canvas">                   <image x:name="imagecontrol" stretch="none" />         </canvas>       </controls:zoomcontrol> </dockpanel>

when user selects image bowse dialog, load image so:

  bmp = new bitmapimage(new uri(filename));   this.imagecontroul.source = bmp;

i added rectangles\adorners specific locations (pixel coordinates) on image user loaded based on image processing. 

var r = new rectangle();  r.strokethickness = 5;  r.stroke = brushes.black;  r.fill = brushes.transparent;  r.width = width;  r.height = height;   canvas.setleft(r, y);  canvas.settop(r, x);   canvas.children.add(r);

however, rectangles not placed in expected locations? wrong scale , location.

thanks,

john

i expect problem canvas expanding fill space rather being locked rectangle. have tool snoop , see bounding boxes of 2 are.

you might able fix horizontal , vercticalalignment on canvas, set them other stretch.

if doesn't work restructure this

<zoombox>   <grid>      <image/>      <canvas/>   </grid> </zoombox>

so image , canvas grouped parent grid being transformed.
