iText embedding Color space (ICC Profile) in PDF Images

Question

I am using iText-7 java library to generate pdf using below code. (I am adding image to pdf doc)

 pdf = new PdfDocument(writer);
 Document document = new Docume         


        

Answer 1

It seems that if the image is manipulated, the ICC profile is lost.

I used the PdfCanvas api to add an image taken from iPhone to the PDF, it looks good to me.

    @Test
    public void testImageColorSpace() throws Exception {

        String imageWithIcc = resourceFile("image-ios-profile.jpg");
        String destination = targetFile("image-colorspace-itext-pdfcanvas.pdf");
        
        PdfDocument pdfDocument = new PdfDocument(new PdfWriter(destination));
        PdfPage page = pdfDocument.addNewPage(new PageSize(mm2pt(400f), mm2pt(400f)));

        PdfCanvas pdfCanvas = new PdfCanvas(page);
        
        ImageData imageData = ImageDataFactory.create(imageWithIcc);

        AffineTransform at = AffineTransform.getTranslateInstance(mm2pt(100f), mm2pt(100f));
        at.concatenate(AffineTransform.getScaleInstance(mm2pt(200f), mm2pt(200f)));
        float[] matrix = new float[6];
        at.getMatrix(matrix);

        pdfCanvas.addImage(imageData, matrix[0], matrix[1], matrix[2], matrix[3], matrix[4], matrix[5]);
        pdfDocument.close();
    }
