Page page = pdf.getPages().get_Item(1);
TextFragmentAbsorber textFragmentAbsorber = new com.aspose.pdf.TextFragmentAbsorber();
page.accept(textFragmentAbsorber);

Hiding image using ImagePlacementAbsorber from the document
With Aspose.PDF for Java you can hide images using ImagePlacementAbsorber from the document:
Document doc = new Document("input.pdf");
for (Page page : doc.getPages()) {

What’s new in Aspose.PDF 21.5
Add API for merging images
Aspose.PDF 21.4 allows you to combine Images. Merges list of image streams as one image stream. Png/jpg/tiff outputs formats are supported, in case of using non supported format output stream encoded as Jpeg by default. Follow the next code snippet:
InputStream inputStream;
ArrayList<InputStream> inputImagesStreams = new ArrayList<InputStream>();
InputStream inputFile300dpi = new FileInputStream("image1.jpg");
try {
inputImagesStreams.add(inputFile300dpi);
InputStream inputFile600dpi = new FileInputStream("image2.jpg");
try {
inputImagesStreams.add(inputFile600dpi);
inputStream = PdfConverter.mergeImages(
inputImagesStreams,
com.aspose.pdf.ImageFormat.Jpeg,
ImageMergeMode.Vertical,
new Integer(1),
new Integer(1)
);
} finally {
if (inputFile600dpi != null) (inputFile600dpi).close();
}
} finally {
if (inputFile300dpi != null) (inputFile300dpi).close();
}
Document doc = new Document();
Page p = doc.getPages().add();
Image image = new Image();
image.setImageStream(inputStream);
p.getParagraphs().add(image);
doc.save("out.pdf");
inputStream.close();
Also you may merge you images as Tiff format:
InputStream inputStream;
ArrayList<InputStream> inputImagesStreams = new ArrayList<InputStream>();
InputStream inputFile1 = new FileInputStream("1.tif");
try {
inputImagesStreams.add(inputFile1);
InputStream inputFile2 = new FileInputStream("2.tif");
try {
inputImagesStreams.add(inputFile2);
inputStream = PdfConverter.mergeImagesAsTiff(inputImagesStreams);
} finally {
if (inputFile2 != null) (inputFile2).close();
}
} finally {
if (inputFile1 != null) (inputFile1).close();
}
Document doc = new Document();
Page p = doc.getPages().add();
Image image = new Image();
image.setImageStream(inputStream);
p.getParagraphs().add(image);
doc.save("out2.pdf");
inputStream.close();
What’s new in Aspose.PDF 21.02
Aspose.PDF v21.02 Sign PDF with PAdES LTV Signatures
final Document document = new Document(inputPdf);

PKCS7 pkcs7 = new PKCS7(getInputPath("cert.pfx"), "password");
//Sign PDF with PAdES LTV Signatures
pkcs7.setUseLtv(true);
signature.sign(1, true, new Rectangle(100, 100, 300, 300), pkcs7);
signature.save(outputPdf);
}
finally { if (document != null) (document).dispose(); }
