Android Question Saving specific region from canvas

[Fusseldieb]

Hi there,
I have drawed a Bitmap with Canvas and then saved it.
But when I save, it captures the entire Screen. I only want the "DestRect".
Here's my code:

Dim C As Canvas
Dim Bitmap1 As Bitmap
Dim Bitmap2 As Bitmap
Dim DestRect As Rect
SetFont("Font.ttf")
C.Initialize(Activity)

Bitmap1.Initialize(File.DirAssets,"Img1.png")
Bitmap2.Initialize(File.DirAssets,"Img2.png")
DestRect.Initialize(0,0,240,180)

C.DrawRect(DestRect,Colors.Blue,True,1)
C.DrawBitmap(Bitmap2,Null,DestRect)
C.DrawBitmap(Bitmap1,Null,DestRect)
C.DrawText("Text1", 20,30,default_font,5,Colors.white,"LEFT")
C.DrawText("Text2", 20,45,default_font,5,Colors.white,"LEFT")
C.DrawText("Text3",DestRect.Right- 20,30,default_font,5,Colors.white,"RIGHT")
C.DrawText("Text4",DestRect.Right- 20,DestRect.Bottom- 20,default_font,5,Colors.white,"RIGHT")

Dim Out As OutputStream
Out = File.OpenOutput(File.DirInternalCache, "TempImage.png", False)
C.Bitmap.WriteToStream(Out, 90, "JPEG")
Out.Close

I have tried clipping and it doesn't work :c

It depends on what you want to do.
As your canvas is initialized to the Activity Canvas.Bitmap is the whole screen.
You could define a Panel with the dimensions of DestRect, set the canvas to this panel.
Draw on this canvas and save it.

Draw on this canvas and save it.

Thanks, but i have tried this now and it doesn't work...
It continues to save the entire screen

......
Dim Panel1 As Panel

Panel1.Initialize("")
Activity.AddView(Panel1,0,0,240,180)

SetFont("Font.ttf")
C.Initialize(Panel1)
.....

EDIT: It worked!!!
The image ws open and my (stupid) cellphone has cached it. So I closed and reopened the image. Now it's just fine.
Thanks so much
