Android Question DPI of saved pic, how to control?

[boten]

I use a mutable bmp & canvas to draw someting and save the picture

Dim MyPic As Bitmap
Dim cvs As Canvas
.
.
.
' initialize pic & cabvas
MyPic.InitializeMutable(Siz,Siz)
cvs.Initialize2(MyPic)
.
.
.
' draw some on canvas
cvs.DrawLine(lastX,lastY,xx,yy,Hue,1dip)
.
.
.  
' save pic  
Out = File.OpenOutput(AppPath, s, False)
MyPic.WriteToStream(Out,100,"JPEG")

the picture is saved with a DPI of 72.

How can the pic saved with DPI of 300?

You can set the density with:

Dim jo As JavaObject = MyPic
jo.RunMethod("setDensity", Array(300))
