Drawing on a canvas - nullpointerexception

[yttrium]

Hey all, I get a fatal null pointer exception whenever I execute the following code:

Dim MyCanvas As Canvas
Dim Bitmap1 As Bitmap
Bitmap1.Initialize(File.DirAssets, "logo.png")
Dim DestRect As Rect
DestRect.Initialize(10dip, 10dip, 10dip + 100dip, 10dip + 100dip)
MyCanvas.DrawBitmap(Bitmap1,, DestRect)
Preview.SetBackgroundImage(MyCanvas.Bitmap)

I use

Dim Preview As Panel

in Globals. The image logo.png does exist and can be loaded and referenced otherwise.

What am I missing?

You are missing a parameter on this line:

MyCanvas.DrawBitmap(Bitmap1,, DestRect)

Check your syntax.

Sorry, I wrote that incorrectly. That line is Bitmap1, Null, DestRect as the documentation states should be used to return the full source bitmap.

You've initialized the Bitmap and Rect, have you initialized the Canvas?

 

[yttrium]

You've initialized the Bitmap and Rect, have you initialized the Canvas?

Oh, wow, how stupid of me. Yup, that fixed it.

Okay, as another little question, how can I make a Panel or ImageView zoom instead of stretch to fit? The only options are Fill, Center, and TopLeft.
