.net - Convert Bitmap to BitmapSource -

-

i have problem converting bitmap bitmapsource, write http://www.codeproject.com/kb/wpf/bitmaptobitmapsource.aspx?msg=3590727 , exceptions: first chance exception of type 'system.invalidoperationexception' occurred in windowsbase.dll :/ must convert bitmap bitmapsource, beacouse use aforge.net caputer image webcam. know why exception ? ( works winforms ) or mayby know library looking similarity aforge can use wpf?

my code:

private void newframehandler(bitmap bitmap) {     bitmapsource bitsrc = null;     var hbitmap = bitmap.gethbitmap();       bitsrc = system.windows.interop.imaging.createbitmapsourcefromhbitmap(          hbitmap,          intptr.zero, int32rect.empty,             system.windows.media.imaging.bitmapsizeoptions.fromemptyoptions());      image1.source = bitsrc; }

the code looks me, though need use pinvoke method deleteobject release memory used hbitmap.

the reason can think of failing, there wrong bitmap being converted.

c# - How to set Z index when using WPF DrawingContext? -

how set z-index drawing object when using drawingcontext.drawxxx() methods? the object drawn last have higher z index. can't change index of drawn objects. way draw in order. if using wpf (as placed tag), can use, example, canvas control. create shapes need like polyline obj = new polyline(); //... // ... set properties of obj and add them canvas uielementcollection: yourcanvasname.children.add(obj); //or yourcanvasname.children.insert(i, obj); first items of collection have higher z index. advantages in way: no need redraw on window changes, can anytime move objects , change order.
