Image canvas BeginScene problem

[Halex10000]

Hi, i tried drawing some graphics on an Image component without success. Calling BeginScene method returns me an error: Type Error: BeginScene called with invalid arguments. Error: Colud not find a method with compatible arguments.

Below is the code called on a onclick method of the form. The Image component is named ImageCanvas

def do_button_click(self, sender): self.ImageCanvas.Bitmap.LoadFromFile('canvas.png') myrect = RectF(50, 30, 150, 200) canvas = self.ImageCanvas.Bitmap.Canvas canvas.BeginScene() canvas.Stroke.Kind = 1; canvas.Stroke.Color = 0xFF00FF00; canvas.StrokeThickness = 4; canvas.DrawEllipse(myrect, 255); canvas.EndScene()

I tried several arguments without any success

Any suggestion?

Thank you

Regards

Alessandro

Hi @Halex10000,

like described in the following documentation, two parameters are expected as part of the FMX.Graphics.TCanvas.BeginScene. Check it out in the link below: https://docwiki.embarcadero.com/Libraries/Sydney/en/FMX.Graphics.TCanvas.BeginScene

If you don't want to input this parameters, you can provide the None type.

Let me know if it works for you.

Hi Imbelo, thank you for the prompt answer.

I tried with canvas.BeginScene(None, None) but I received the same error as before.

Thanks
