iOS Question About BMP by B4I


Licensed User
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.
