iOS Question About BMP by B4I

[lgg]

Hi,
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.

Another option is to use B4XCanvas: https://www.b4x.com/android/forum/threads/b4x-xui-drawing-with-b4xcanvas.85113/#content
It is also covered in the booklets: https://www.b4x.com/android/documentation.html
