4 years ago Hi, do you know if "whale.jpg" has transparent pixels or if the bg is just white? Kumo works by placing text where ever it finds transparent pixels. A future feature request may be supporting a TRANSPARENT_COLOR, so that we can say "white or some other color is considered transparent"

3 years ago Hi! @kennycason , I want to involve in this issue by adding the feature offering user the option to transparentize the background of the picture without a transparent background. I have wrote some code to provide the feature and will do the PR later. The PR: #99
the code is ,
public static void gen() throws IOException { final FrequencyAnalyzer frequencyAnalyzer = new FrequencyAnalyzer(); frequencyAnalyzer.setWordFrequenciesToReturn(70); frequencyAnalyzer.setMinWordLength(3); File f = new File("F:/temp/text.txt"); final List wordFrequencies = frequencyAnalyzer.load(new FileInputStream(f));
final Dimension dimension = new Dimension(500, 312);
final WordCloud wordCloud = new WordCloud(dimension, CollisionMode.PIXEL_PERFECT);
wordCloud.setPadding(2);
wordCloud.setBackground(new PixelBoundryBackground("F:/temp/whale.jpg"));
wordCloud.setColorPalette(new ColorPalette(new Color(0x4055F1), new Color(0x408DF1), new Color(0x40AAF1), new Color(0x40C5F1), new Color(0x40D3F1), new Color(0xFFFFFF)));
wordCloud.setFontScalar(new LinearFontScalar(10, 40));
wordCloud.build(wordFrequencies);
wordCloud.writeToFile("whale_wordcloud_small.png");
}
but,the background of whale_wordcloud_small.png is a rectangle ,not a whale. could anyone know how to resolve it?thanks
