如何用Java读取OS X*.icns文件
我想将OS X中的*.icns文件读入BuffereImage。帮助尝试以下操作:如何用Java读取OS X*.icns文件,java,macos,graphics,Java,Macos,Graphics,我想将OS X中的*.icns文件读入BuffereImage。帮助尝试以下操作: 这实际上来自:您需要先将ICN转换为另一种图像类型,加载此图像后,您可以将其删除。这是如何将PNG转换为ICN的,因此您只需要以相反的方式进行: public static void Png(File png, File icns) throws IOException{ ImageIcon image = new ImageIcon(ImageIO.read(png)); ImageIconAs
这实际上来自:您需要先将ICN转换为另一种图像类型,加载此图像后,您可以将其删除。这是如何将PNG转换为ICN的,因此您只需要以相反的方式进行:
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);
}
}
您只需使用此命令调用操作:
Png(Png_文件、icns_文件) 你可以自己做。它使用以下图标格式:
- *.ico-Windows图标
- *.icl-Windows图标库
- *.icns-麦金塔图标
