Use Guideline
Increase the following to your structure file:
RasmContext
RasmContext makes it possible for you to manage the brush configuration, undo/redo, reset transformation, and far more. RasmContext can be accessed from RasmView:
val rasmView = findViewById<RasmView>(R.id.rasmView)
val rasmContext = rasmView.rasmContext
Shifting the brush
You can use the BrushesRepository to get an currently described brush.
val brushesRepository = BrushesRepository(resources)
rasmContext.brushConfig = brushesRepository.get(Brush.Marker)
The adhering to brushes are currently outlined:
enum course Brush
Pencil,
Pen,
Calligraphy,
AirBrush,
Marker,
HardEraser,
SoftEraser,
Brush coloration
Below is how to transform the brush shade:
rasmContext.brushColor = Coloration.Red
rasmContext.brushColor = 0xff2187bb.toInt() //ARGB
The alpha channel worth is ignored, you can control alpha by environment brushConfig.stream.
Brush sizing and other configurations
val brushConfig = rasmContext.brushConfig
brushConfig.sizing = .5f
brushConfig.move = .25f
brushConfig.isEraser = correct
Tailor made brushes
val myStampBitmap = ...
val customBrushConfig = BrushConfig()
customBrushConfig.stamp = BrushStamp.BitmapStamp(myStampBitmap)
customBrushConfig.sizing = .25f
customBrushConfig.spacing = .1f
rasmContext.brushConfig = customBrushConfig
Drawing on a bitmap (your possess impression).
val imageBitmap = ... //load your bitmap regardless of whether from a URI or methods
rasmContext.setRasm(imageBitmap)
rasmView.resetTransformation()
Getting the drawing
val drawingBitmap = rasmContext.exportRasm()
Track record colour
rasmContext.setBackgroundColor(Colour.BLACK)
Undo/redo
val rasmState = rasmContext.point out
rasmState.undo()
rasmState.redo()
But you do not want to maintain your buttons enabled when an undo/redo is not feasible, you can hear to point out updates:
undoButton.setOnClickListener
rasmState.undo()
redoButton.setOnClickListener
rasmState.redo()
rasmState.addOnStateChangedListener
undoButton.isEnabled = rasmState.canCallUndo()
redoButton.isEnabled = rasmState.canCallRedo()
undoButton.isEnabled = rasmState.canCallUndo()
redoButton.isEnabled = rasmState.canCallRedo()
Clearing the drawing
Enabling rotation
rasmContext.rotationEnabled = legitimate
Resetting the transformation
rasmView.resetTransformation()
