DrawCircle creates the brush for you and calls DrawCircle2:

Bc.Dr Bug? B4XCanvas InitializeArc - Erel (first post)    May 14, 2019   (1 reaction) This is the behavior of the native API. You will need to use InitializeOval for this case. Note that you can also achieve this effect with BitmapCreator: Sub Activity_Create(FirstTime As Boolean) Activity.LoadLayout("1") bc.Initialize(ImageView1.Width, ImageView1.Height) Dim brush As BCBr B4A Question How crop with b4xcanvas and a trasparent color? - Erel (first post)    Aug 04, 2019   (2 reactions) Initialize(bmp.Width + 1, bmp.Height + 1) Dim brush As BCBrush = bcbrush.CreateBrushFromBitmapCreator(bcbrush) Dim r As B4XRect r.Initialize(0, 0, bc.mWidth - 1, bc.mHeight - 1) bc.DrawRectRounded2(r, brush, True, 0, Radius) If TopLeft = False Then r.Initialize(0, 0, Radius, Ra B4A Question Telegram theme change animation - AmirMK82 (first post)    Aug 23, 2021 I have tested it(not worked), And this is my code : Sub drawWithAnimatoin Dim bc As BitmapCreator Dim brush As BCBrush bc.Initialize(100%x, 100%y) Dim bmp As B4XBitmap = Root.Snapshot brush = bc.CreateBrushFromBitmap(bmp) Root.Color = Colors.White For i=0 To Pan B4A Question 360 in 10 seconds - Erel (first post)    May 20, 2020   (5 reactions) Sub Process_Globals Private fx As JFX Private MainForm As Form Private ImageView1 As B4XView Private bc As BitmapCreator Private xui As XUI End Sub Sub AppStart (Form1 As Form, Args() As String) MainForm = Form1 MainForm.RootPane.LoadLayout("1") 'Load the layout file. B4J Question 3 gradiant fill with drawarc - Erel (first post)    Aug 01, 2023   (1 reaction) There is no built-in sweep gradient like this in BitmapCreator. It is possible to create one with some work (check the source code).
Another option is to use a left right gradient:
