如何用设定的单词数使原始图像的单词云？

Question

如何制作图像的词云图像。

像上面的原始图片一样输出

我正在尝试使用https://github.com/bachors/Android-Img2Ascii

将图像粘贴到Ascii

 TextView textAsc=(TextView)findViewById(R.id.textAsc);
    Bitmap image = BitmapFactory.decodeResource(getResources(), R.drawable.step0001);
// Bitmap image = BitmapFactory.decodeFile(filename);

    new Img2Ascii()
            .bitmap(image)
            .quality(4) // 1 - 5
            .color(true)

            .convert(new Img2Ascii.Listener() {
                @Override
                public void onProgress(int percentage) {
                    textAsc.setText(String.valueOf(percentage) + " %");
                }
                @Override
                public void onResponse(Spannable text) {
                    textAsc.setText(text);
                }
            });
