    fileName2 = "background.png"
    out2 = File.OpenOutput (FP, fileName2 ,  False)
    cvs2.Bitmap.WriteToStream(out2,  100, "PNG")

How are you drawing the bitmap to the canvas?

yes

i crop the image with canvas later i save this canvas to image
1 crop is 30%x 30%x 30%y 30%Y

and crop 2
is 0%x 50%x 0%y 100%y <<<< the problem is this crop this take a original picture - 50% but take a picture with bad quality
