You can use this (untested) code to create a mutable bitmap with different configuration: Sub Create565Bitmap(Width As Int, Height As Int) As Bitmap Dim jo As JavaObject Return jo.InitializeStatic("android.graphics.Bitmap").RunMethod("createBitmap", Array(Width, Height, "RGB_565")) End Sub

Create a process global mutable bitmap when the activity is first created and draw on this bitmap with Canvas.Initialize2 instead of Canvas.Initialize(iv). Set this bitmap as the ImageView background.

Sub Name: DrawRoundBitmap Description: This code uses Path object to draw a round bitmap at the center of a transparent mutable bitmap. Sub Activity_Create(FirstTime As Boolean) Dim cvs As Canvas = CreateBitmap DrawRoundBitmap(cvs, LoadBitmap(File.DirAssets, "1.jpg")) Activity.SetBackgro

Algorithm-less tricky way Create a mutable bitmap with the same dimensions as the view you are showing. No need to attach it to a view. Initialize a canvas to it. Clip the path and fill it Red. When you want to see if X, Y is inside the path, just check the color of this point in the bitmap (Surpr

If you follow the code, you'll see a Bitmap created, called i. This Bitmap is initialized as mutable. Then a Canvas is created to draw on i. The icon is drawn onto the Canvas (and hence the Bitmap). Then the Bitmap is put as an Extra into the Intent "in". This Intent is what is eventually broadcast.

You need to make sure that the aspect ratio of the ImageView and the Image are the same. Or you could use a mutable bitmap to preserve the original resolution and aspect ratio: ' Load bitmap Dim bmpInput As Bitmap = LoadBitmap(File.DirAssets, "Test.jpg") ' Create a mutable bitmap a

You should declare a bitmap, and initialize mutable with the width and height of your display. Then initialize a canvas with this bitmap (canvas.Initialize2(...)) and draw onto it. If you only want one bit per pixel, then draw only with one color Once drawn, you can get the pixels in any position
