    I'm using B4I. I have a question about BMP editing like Initialize Mutable in B4A.
    I want to draw a straight line directly in a BMP picture or put one image on top so that the two can be seen combined to generate a new picture.
    What should I do?
    Looking forward to a response, please help me, thank you very much!

    1. Use BitmapCreator.
    2. Initialize it.
    3. Then call DrawBitmap to draw your image.
    4. Then call DrawLine to draw a line.
    5. Then use the end result from BitmapCreator.Bitmap as you want.
