Java 如何将ICC_配置文件（Adobe98）嵌入IIOMetadata并使用ImageIO写入PNG？

我试图使用

ImageIO

将

buffereImage

写入png文件，但每次我向

iimetadata

添加

ICC_配置文件时，生成的png图像没有嵌入
ICC_配置文件
，并且在生成的png文件上运行
ImageMagick
标识会产生错误

我需要的是添加ICC_配置文件的工作代码。我承认我对ImageIO有点生疏。我的想法是，我只需将配置文件添加到标题中，用于渲染图像的任何内容都应该找到配置文件，并在相关的颜色空间中显示图像（如果支持）。我是否错过了我应该对这张图片做的其他事情

另外，我想明确一点，我只想使用来自JAI的ImageIO，而不是ColorConvertOp，因为JAI已经有7年没有开发了，在我看来，最好的方法是使用标准JDK类。这是否可能和/或是否有其他人能够实现

我的代码：

Iterator i = ImageIO.getImageWritersByFormatName("PNG");
    if (i.hasNext()) {
        ImageWriter imageWriter = (ImageWriter) i.next();
        ImageWriteParam param = imageWriter.getDefaultWriteParam();
        ImageTypeSpecifier its = new ImageTypeSpecifier(bi.getColorModel(), bi.getSampleModel());
        IIOMetadata iomd = imageWriter.getDefaultImageMetadata(its, param);
        String formatName = "javax_imageio_png_1.0";
        Node node = iomd.getAsTree(formatName);

        //add resolution
        IIOMetadataNode phys = new IIOMetadataNode("pHYs");
        phys.setAttribute("unitSpecifier", "unknown");
        phys.setAttribute("pixelsPerUnitXAxis", "300");
        phys.setAttribute("pixelsPerUnitYAxis", "300");

        //add ICC PROFILE
        IIOMetadataNode iccp = new IIOMetadataNode("iCCP");
        //ICC_Profile pro = Util.getAdobeRGBICCProfile();
        iccp.setUserObject(parameters.getOriginalICC());
        iccp.setAttribute("profileName", "AdobeRGB1998");
        iccp.setAttribute("compressionMethod", "deflate");

        node.appendChild(phys);
        node.appendChild(iccp);

        try {
            iomd.setFromTree(formatName, node);
        } catch (IIOInvalidTreeException e) {
            System.out.println("IIOInvalidTreeException Occurred setting resolution on PNG EXIF Header.");
            e.printStackTrace(System.out);
        }

        IIOImage iioimage = new IIOImage(bi, null, iomd);
        try {
            imageWriter.setOutput(new FileImageOutputStream(new File(fileName)));
            imageWriter.write(iioimage);
        } catch (IOException e) {
            System.out.println("Error Occurred setting resolution on PNG.");
            e.printStackTrace(System.out);
        }
    }

我之所以这么问，是因为我不认为您的ICC配置文件是压缩的
字节[]
。你说“这不是问题”，但我真的认为它是。：-）

如果我没有对ICC配置文件应用deflate压缩，我会从ExifTool收到与您从identify收到的类似警告

Warning                         : Error inflating iCCP
ICC Profile                     : (Binary data 526 bytes, use -b option to extract)

如果我正确地将deflate压缩应用于ICC配置文件，ICC配置文件将正确标识为“Adobe RGB 1998”

以下代码适用于我：

public class PNGICCProfileIssue {
    public static void main(String[] args) throws IOException {
        File input = new File(args[0]);
        BufferedImage image = ImageIO.read(input);

        Iterator<ImageWriter> writers = ImageIO.getImageWritersByFormatName("PNG");
        if (!writers.hasNext()) {
            return;
        }

        ImageWriter writer = writers.next();
        writer.setOutput(ImageIO.createImageOutputStream(new File(input.getParent(), input.getName().replace('.', '_') + "_icc.png")));

        IIOMetadata imageMetadata = writer.getDefaultImageMetadata(ImageTypeSpecifier.createFromRenderedImage(image), writer.getDefaultWriteParam());

        //add ICC PROFILE
        IIOMetadataNode iccp = new IIOMetadataNode("iCCP");
        ICC_ColorSpace colorSpace = (ICC_ColorSpace) ColorSpaces.getColorSpace(ColorSpaces.CS_ADOBE_RGB_1998);
        iccp.setUserObject(getAsDeflatedBytes(colorSpace));
        iccp.setAttribute("profileName", "AdobeRGB1998");
        iccp.setAttribute("compressionMethod", "deflate");

        Node nativeTree = imageMetadata.getAsTree(imageMetadata.getNativeMetadataFormatName());
        nativeTree.appendChild(iccp);
        imageMetadata.mergeTree(imageMetadata.getNativeMetadataFormatName(), nativeTree);

        writer.write(new IIOImage(image, null, imageMetadata));
    }

    private static byte[] getAsDeflatedBytes(ICC_ColorSpace colorSpace) throws IOException {
        byte[] data = colorSpace.getProfile().getData();

        ByteArrayOutputStream deflated = new ByteArrayOutputStream();
        DeflaterOutputStream deflater = new DeflaterOutputStream(deflated);
        deflater.write(data);
        deflater.flush();
        deflater.close();

        return deflated.toByteArray();
    }

我认为这个要求应该在元数据文档中记录下来，因为我不得不告诉你这有点让人困惑

祝你好运！
什么是
parameters.getOriginalICC（）
？一个
ICC_配置文件
实例，一个
byte[]
或其他什么？你确定它是压缩的吗？这只是一种使用ICC_配置文件从本地文件获取byte[]的方便方法。getInstance（pathToFile）。这不是问题。而deflate compression是默认设置，也是您可以根据设置在标题中设置此字段的唯一方法。您是正确的。我不应该对压缩不屑一顾。谢谢。
