Answer 1

试试这个：http://code.google.com/p/appengine-awt/source/browse/trunk/apache-sanselan/src/main/java/org/apache/sanselan/formats/icns/IcnsDecoder.java?spec=svn8&r=8

它实际上来自：http://incubator.apache.org/sanselan/site/index.html

您需要先将ICNS转换为另一种镜像类型，加载此镜像后，您可以将其删除。这就是如何将PNG转换为in，所以您只需要以相反的方式进行操作：

public static void Png(File png, File icns) throws IOException{
    ImageIcon image = new ImageIcon(ImageIO.read(png));
    ImageIconAs(image, icns);
}

public static void ImageIconAs(ImageIcon ii, File icns) throws IOException{IconAs((Icon)ii,icns);}

public static void IconAs(Icon icon, File icns) throws IOException{
        if (icon != null) {
                BufferedImage bi = new BufferedImage(icon.getIconWidth(), icon.getIconHeight(), BufferedImage.TYPE_INT_ARGB );
                Graphics2D g = bi.createGraphics();
                icon.paintIcon(new Canvas(), g, 0, 0 );
                g.dispose();
                File outputfile = new File("temp000.png");
                ImageIO.write(bi, "png", outputfile);
                execTerminal(new String[]{ "sips", "-s", "format", "tiff", 
                        "temp000.png","--out", "temp000.tiff" });  
                File apaga2 = new File("temp000.png");
                apaga2.delete();
                execTerminal(new String[]{ "tiff2icns", "-noLarge", 
                        "temp000.tiff", icns.getAbsolutePath()});
                File apaga = new File("temp000.tiff");
                apaga.delete();
        }
    }

static void execTerminal(String[] cmd){
        int exitCode = 0;
        try {
            exitCode = Runtime.getRuntime().exec(cmd).waitFor();
        } 
        catch (InterruptedException e) {e.printStackTrace();}
        catch (IOException e) {
            if (exitCode != 0) System.out.println("ln signaled an error with exit code " + exitCode);
        }
    }

您只需使用此命令来调用操作：

Png(png_file，icns_file)；

你可以使用IconManager。它使用以下图标格式：

• *.ico - Windows Icon
• *.icl - Windows图标Library
• *.icns - Macintosh图标
