我在將png轉換為tiff時遇到問題.轉換很順利,但圖像很大.我認為問題是我沒有正確地進行壓縮？任何人都有任何建議？

這是代碼示例

public static void test() throws IOException {

// String fileName = "4958813_1";

String fileName = "4848970_1";

String inFileType = ".PNG";

String outFileType = ".TIFF";

ImageIO.scanForPlugins();

File fInputFile = new File("I:/HPF/UU/" + fileName + inFileType);

InputStream fis = new BufferedInputStream(new FileInputStream(

fInputFile));

PNGImageReaderSpi spi = new PNGImageReaderSpi();

ImageReader reader = spi.createReaderInstance();

ImageInputStream iis = ImageIO.createImageInputStream(fis);

reader.setInput(iis, true);

BufferedImage bi = reader.read(0);

TIFFImageWriterSpi tiffspi = new TIFFImageWriterSpi();

ImageWriter writer = tiffspi.createWriterInstance();

//Iterator iter = ImageIO.getImageWritersByFormatName("TIFF");

//ImageWriter writer = iter.next();

ImageWriteParam param = writer.getDefaultWriteParam();

param.setCompressionMode(ImageWriteParam.MODE_EXPLICIT);

param.setCompressionType("LZW");

param.setCompressionQuality(0.5f);

File fOutputFile = new File("I:\\HPF\\UU\\" + fileName + outFileType);

ImageOutputStream ios = ImageIO.createImageOutputStream(fOutputFile);

writer.setOutput(ios);

writer.write(bi);

}
