B4J Question Path add Arc?

[ilan]

i am missing some features in the path object in b4x.
in b4a i can use Javaobject to add more options like addarc using the code as described here:

Add Arc to Path

Dim p As Path p.Initialize(0, 0) Dim jo As JavaObject = p Dim x = 100dip, y = 100dip, radius = 100dip As Float jo.RunMethod("addCircle", Array As Object(x, y, radius, "CW")) cvs.ClipPath(p) Where can I find references to obtain more info on Adding different Draws to a Path...

www.b4x.com

is there a b4x solution for that? i would like to make a jigsaw puzzle but using b4x code.
any ideas how to do that?

Can you post a mockup of the shape you want to draw?

 

[ilan]

i will need to create an algorithm to draw those shapes that should also be resizeable.

do you want the points for a shape? or do you want an image?

the shapes should look like this:

You may have a look at jCanvasExt.

You may have a look at jCanvasExt.

thanx klaus, will it work with b4i and b4a too?

No, onl B4J, it uses Java objects.
The documentation is here: https://docs.oracle.com/javase/8/javafx/api/javafx/scene/canvas/GraphicsContext.html

In B4A you may have a look at ABExtDrawing library.

I have never looked deeper for B4i.

For cross-platform methods you may have a look at this thread: https://www.b4x.com/android/forum/threads/b4x-bitmapcreator.105384/#content
The test project in this thread contains AddBezier routines, you could make your own arc routines based on the same principle: add short lines like every degree.
