Hello,
Firstly, I am a huge fan of your work. It's just amazing and the best part about it is that its faster than other methods and that it can run on android without native. A huge thank you, for your effort.
I am implementing your method in my app to generate lowpoly wallpapers. It works absolutely fine when I use a bitmap which is scaled to 1440x1080 but the problem in that is the images (which are of different sizes) come out with a bad aspect ratio. So in order to scale them properly, I use two methods -
public int getScreenWidth() { int densityDpi = (int) Math.floor((double) width * (double) getScreenHeight() / (double) height); return densityDpi; }

and
public int getScreenHeight() { DisplayMetrics metrics = getResources().getDisplayMetrics(); int densityDpi = (int) (metrics.heightPixels * 1.2); return densityDpi; }

After that, I scale the bitmap to getScreenWidth()xgetScreenHeight(). But the problem in this case is that it gives me java.lang.IllegalArgumentException: No containing triangle

Here is the full stack trace-

Now the line at which the app crashes is - dt.delaunayPlace(new Pnt(width - 1, 1));

*What I have tried - *
For different devices with different display sizes and different wallpapers with varying dimensions, the app cashes at one of the following lines -
dt.delaunayPlace(new Pnt(1, 1)); dt.delaunayPlace(new Pnt(1, height - 1)); dt.delaunayPlace(new Pnt(width - 1, 1)); dt.delaunayPlace(new Pnt(width - 1, height - 1));

Please note -
I cannot extract the image from a imageView, because the wallpaper would be of small dimension then and will get pixelated on setting it as wallpaper.

Thank you.
