Android Question Rotating camera pic without saving temporary file

[Alessandra Pellegri]

I am actually doing this:

Sub Camera1_PictureTaken (Data() As Byte)
   camera1.StartPreview
   camera1.SavePictureToFile(Data,File.DirDefaultExternal, "tmp.jpg")
   Dim bmp As Bitmap=LoadBitmapSample(File.DirDefaultExternal, "tmp.jpg",100%x,100%y)
   Dim bm As BitmapExtended
   bmp=bm.rotateBitmap(bmp,-rotated90)   
   Dim Out As OutputStream
   Out = File.OpenOutput(File.DirDefaultExternal, "Test.png", False)
   bmp.WriteToStream(Out, 100, "JPEG")
   Out.Close
.....

where rotated90 is a variable updated with accelerometer.

Now I would like to do the rotation without uncompressing/recompressing jpg and without using a temporary file.

Is it possible ?

You can use this code to rotate a bitmap: https://www.b4x.com/android/forum/threads/file-rotation-cant-get-it-done.41391/#post-248945

Ok, how do I convert from byte() to bitmap ?

Thank you

Search for byte to bitmap. There are many code examples.
