It's invalid to setBackground with a picture,the result is always a rectangle background picture

[panglei1984]

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<WordFrequency> 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

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"

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
