Android Question Rotate a certain image contained in a folder from code

Matteo Granatiero · Dec 21, 2017

I would like to rotate a certain image "jeans.jpg" contained in a certain folder, 90 degrees directly from the code, therefore without loading it on an ImageView or other.

B4X:

Dim b As Bitmap = LoadBitmap(...).Rotate(90)
Dim out As OutputStream = File.OpenOutput(...)
b.WriteToStream(...)
out.Close

Consider using LoadBitmapResize instead of LoadBitmap if the image files can be large.

What do you mean by: the code not reponse
You need to post your code after Erel's tips. Where are your code lines that Erel has helped you with that you need to complete that show your file and its location.
