bitmap question II

That should give you enough to go on.

not what i looking for
simply, i want to display one part of some previously loaded bitmap (one part od 100x100 from 1000x1000) in imageview form

If this is a jpeg file then you can use the JPEG library to only load this part.
Otherwise you will need to load the complete image and use Canvas to draw part of it to the ImageView.

ok, i try to use canvas but without result
this is my code

Dim Canvas1 As Canvas
Dim DestRect As Rect
Dim SrcRect As Rect

Activity.LoadLayout("320p")
slika.initialize(File.DirRootExternal, "z.jpg")
DestRect.Initialize(10dip, 10dip, 10dip + 100dip, 10dip + 100dip)
SrcRect.initialize (0,0,30,30)
Canvas1.DrawBitmap(slika, SrcRect, DestRect)
iv1.SetBackgroundImage (Canvas1.Bitmap)

it freezes on canvas1.drawbitmap
???


so... i just need that connection between canvas and imageview because later i want imageview to be "clickable"

Please use [ code ] [ /code ] tags (without spaces) when posting code.

Press F5 and check the error in the logs. You didn't initialize Canvas.
