Save your bitmap to a file and then use loadbitmapresize

LoadBitmap / LoadBitmapResize / LoadBitmapSample

This tutorial explains the differences between the three methods. The bottom line is that the best option is to use LoadBitmapResize and set the container gravity, if possible, to Gravity.CENTER. LoadBitmap - Simply loads the bitmap as-is. Loading unknown bitmap files with LoadBitmap is...

Yes i know that, but i don't want to save to file. Why should i do that? I have the data img.Bitmap, is there no other solution ?

    Dim bmp As Bitmap = Base64EncodeDecodeImage.Base64StringToImage(kont)

    Dim newW As Int = 100
    Dim newH As Int = 100

    Dim resized As Bitmap
    resized.InitializeMutable(newW, newH)

    Dim cvs As Canvas
    cvs.Initialize2(resized)
    cvs.DrawBitmap(bmp, Null, cvs.TargetRect)
img.Bitmap=resized

Using the canvas, you can resize without going to a file. To be tested.

Did you try

img.Bitmap = Base64EncodeDecodeImage.Base64StringToImage(kont).Resize(100, 100, True)
