What’s new in Aspose.PDF 24.8
Since 24.8, support for the PDF/A-4 format:
Document document = new Document(inputPdf);
// Only PDF-2.x documents can be converted to PDF/A-4
document.convert(new ByteArrayOutputStream(), PdfFormat.v_2_0, ConvertErrorAction.Delete);
boolean converted = document.convert(logFile, PdfFormat.PDF_A_4, ConvertErrorAction.Delete);
document.save(outputFile);
Also, is it possible to add alternative text for the Image Stamp:
The AlternativeText property has been added to ImageStamp - if a value is assigned to it, then when adding an ImageStamp to a document it has Alternative Text.
String p1_Alt1 = "*** page 1, Alt text 1 ***",
p1_Alt2 = "*** page 1, Alt text 2 ***",
p2_Alt1 = "--- page 1, Alt text 1 ---",
p2_Alt2 = "--- page 1, Alt text 2 ---";
StructTreeRootElement structTreeRoot = document.getTaggedContent().getStructTreeRootElement();
ImageStamp imageStamp = new ImageStamp(dataDir + "test.jpg");
imageStamp.setXIndent(100);
imageStamp.setYIndent(700);
imageStamp.setWidth(50);
imageStamp.setHeight(50);
imageStamp.setQuality(100);
imageStamp.setAlternativeText(p1_Alt1);
// To page 1
document.getPages().get_Item(1).addStamp(imageStamp);
imageStamp.setYIndent(500);
imageStamp.setAlternativeText(p1_Alt2);
document.getPages().get_Item(1).addStamp(imageStamp);
// To page 2
document.getPages().add();
imageStamp.setXIndent(400);
imageStamp.setYIndent(700);
imageStamp.setWidth(50);
imageStamp.setHeight(50);
imageStamp.setAlternativeText(p2_Alt1);
document.getPages().get_Item(2).addStamp(imageStamp);
imageStamp.setYIndent(500);
imageStamp.setAlternativeText(p2_Alt2);
document.getPages().get_Item(2).addStamp(imageStamp);
// Save document
document.save(outFile);
Also, the following code shows how to add AlternativeText in the existing images in FigureElements.
String inFile = dataDir + "46040.pdf";
String outFile = dataDir + "46040_1_out.pdf";
Document document = new Document(inFile);
ITaggedContent taggedContent = document.getTaggedContent();
StructureElement rootElement = taggedContent.getRootElement();
Iterator tmp0 = (rootElement.getChildElements()).iterator();
while (tmp0.hasNext())
{
com.aspose.pdf.tagged.logicalstructure.elements.Element element = (com.aspose.pdf.tagged.logicalstructure.elements.Element)tmp0.next();
if (element instanceof com.aspose.pdf.tagged.logicalstructure.elements.FigureElement)
{
com.aspose.pdf.tagged.logicalstructure.elements.FigureElement figureElement = (com.aspose.pdf.tagged.logicalstructure.elements.FigureElement)element;
// Set Alternative Text
figureElement.setAlternativeText("Figure alternative text (technique 1)");
}
}
// Save document
document.save(outFile);
What’s new in Aspose.PDF 24.7
Since the 24.7 release, as part of the editing tagged PDF, were added methods on Aspose.Pdf.LogicalStructure.Element:
- Tag (add tags to specific operators like images, text, and links)
- InsertChild
- RemoveChild
- ClearChilds
These methods allow you to edit PDF file tags, for example:
Document document = new Document(dataDir + "test.pdf");
// Retrieve the first page of the document.
Page page = document.getPages().get_Item(1);
// Initialize variables to hold BDC (Begin Dictionary Context) elements for different purposes.
BDC imageBdc = null;
BDC pBdc = null;
BDC link1Bdc = null;
BDC link2Bdc = null;
BDC helloBdc = null;
// Iterate through the contents of the page.
for (int i = 1; i <= page.getContents().size(); i++)
{
// Get the current operator from the page contents.
Operator op = page.getContents().get_Item(i);
// Check if the operator is an instance of BDC.
if (op instanceof BDC) {
BDC bdc = (BDC)op; // Cast the operator to BDC type.
if (bdc != null)
{
// Check if the MCID (Mark Content Identifier) of the BDC is 0.
if (bdc.getProperties().getMCID()[0] != null && bdc.getProperties().getMCID()[0] == 0)
{
helloBdc = bdc; // Store the BDC for later use.
}
}
}
// Check if the operator is an instance of Do (Draw Object).
if (op instanceof Do) {
Do doXobj = (Do)op; // Cast the operator to Do type.
if (doXobj != null)
{
// Create a new BDC for an image and insert it into the page contents.
imageBdc = new BDC("Figure");
page.getContents().insert(i - 2, imageBdc); // Insert before the current operator.
i++; // Increment the index to account for the inserted BDC.
page.getContents().insert(i + 1, new EMC()); // Insert an EMC (End Mark Content).
i++; // Increment the index again.
}
}
// Check if the operator is an instance of TextShowOperator (for text display).
if (op instanceof TextShowOperator) {
TextShowOperator tx = (TextShowOperator)op; // Cast the operator to TextShowOperator type.
if (tx != null)
{
// Check for specific text content and insert corresponding BDCs.
if (tx.getText().contains("efter Ukendt forfatter er licenseret under"))
{
pBdc = new BDC("P");
page.getContents().insert(i - 1, pBdc); // Insert before the current operator.
i++; // Increment the index.
page.getContents().insert(i + 1, new EMC()); // Insert an EMC.
i++; // Increment the index.
}
if (tx.getText().contains("CC"))
{
link1Bdc = new BDC("Link");
page.getContents().insert(i - 1, link1Bdc); // Insert before the current operator.
i++; // Increment the index.

What’s new in Aspose.PDF 24.6
Since 24.6 Aspose.PDF for Java allows to sign PDF with java.security.cert.X509Certificate, java.security.PrivateKey:
This code retrieves a certificate and private key from the certificate store and then uses them to apply a digital signature to the first page of a PDF document.
KeyStore trustStore = KeyStore.getInstance("Windows");
trustStore.load(null, null);
java.security.cert.X509Certificate certificate = (java.security.cert.X509Certificate) trustStore.getCertificate("ProfMoriarty");
PrivateKey key = (PrivateKey) trustStore.getKey("ProfMoriarty", null);
PdfFileSignature pdfSign = new PdfFileSignature(getInputPdf());
Signature signature = new ExternalSignature(certificate, key);
pdfSign.sign(1, "reasonTest", "contactTest", "locationTest", true, new java.awt.Rectangle(1, 691, 100, 100), signature);
pdfSign.save("PDFJAVA.pdf");
pdfSign.close();
What’s new in Aspose.PDF 24.5
Since the 24.5 release, the Form Editor Plugins implemented.
How to Edit Forms in PDF using Form Editor
- Set your license keys
- Create an instance of the FormEditor class, which provides methods for manipulating PDF forms
- Create an instance of the FormEditorAddOptions class, which specifies the options for adding form fields to a PDF document
- Add an input file source and an output file source to the FormEditorAddOptions object, using the FileDataSource class which represents a file path or stream
- Call the Process method of the FormEditor object, passing the FormEditorAddOptions object as a parameter
- Access the result using ResultContainer.resultCollection
// Specify the input and output paths for the PDF files.
String inputPath = "sample.pdf";
String outputPath = "out.pdf";
// Create an instance of the FormEditor plugin.
FormEditor pdfFormPlugin = new FormEditor();
// Create options for adding form fields.
ArrayList<FormFieldCreateOptions> options = new ArrayList<FormFieldCreateOptions>();
// Create a textbox form field.
FormTextBoxFieldCreateOptions tmp1 = new FormTextBoxFieldCreateOptions(1, new Rectangle(10, 600, 90, 610));
tmp1.setValue("TextBoxField");
tmp1.setColor(Color.getChocolate());
tmp1.setPartialName("TexBoxField");
options.add(tmp1);
// Create a combo box form field.
FormComboBoxFieldCreateOptions tmp2 = new FormComboBoxFieldCreateOptions(1, new Rectangle(310, 800, 350, 815));
tmp2.setColor(com.aspose.pdf.Color.getRed());
tmp2.setEditable(new Boolean[]{true});
tmp2.setDefaultAppearance(new DefaultAppearance("Arial Bold", 12, java.awt.Color.GREEN));
ArrayList<String> list1 = new ArrayList<String>();
list1.add("p1");
list1.add("p2");
list1.add("p3");
tmp2.setOptions(list1);
tmp2.setSelected(new Integer[]{2});
tmp2.setPartialName("ComboBoxField");
options.add(tmp2);
// Create a checkbox form field.
FormCheckBoxFieldCreateOptions tmp3 = new FormCheckBoxFieldCreateOptions(1, new Rectangle(10, 700, 90, 715));
tmp3.setValue("CheckBoxField 1");
tmp3.setPartialName("CheckBoxField_1");
tmp3.setColor(Color.getBlue());
options.add(tmp3);
// Create a checkbox form field.
FormCheckBoxFieldCreateOptions tmp4 = new FormCheckBoxFieldCreateOptions(1, new Rectangle(100, 700, 190, 715));
tmp4.setChecked(new Boolean[]{true});
tmp4.setValue("CheckBoxField 2");
tmp4.setDefaultAppearance(new DefaultAppearance("Arial Bold", 12, java.awt.Color.GREEN));
tmp4.setStyle(new Integer[]{BoxStyle.Cross});
options.add(tmp4);
// Create a checkbox form field.
FormCheckBoxFieldCreateOptions tmp5 = new FormCheckBoxFieldCreateOptions(1, new Rectangle(200, 700, 390, 715));
tmp5.setPartialName("CheckBoxField_3");
tmp5.setValue("CheckBoxField 3");
tmp5.setStyle(new Integer[]{BoxStyle.Star});
tmp5.setChecked(new Boolean[]{true});
tmp5.setTextHorizontalAlignment(new HorizontalAlignment[]{HorizontalAlignment.Center});
options.add(tmp5);
FormEditorAddOptions opt = new FormEditorAddOptions(options);
// Add input and output files to the options.
opt.addInput(new FileDataSource(inputPath));
opt.addOutput(new FileDataSource(outputPath));
// Process the form fields using the plugin.
ResultContainer results = pdfFormPlugin.process(opt);
This release allows us to work with PDF layers. For example:
- lock a PDF layer
- extract PDF layer elements
- flatten a layered PDF
- merge All Layers inside the PDF into one
Lock a PDF layer
Since the 24.5 release, you can open a PDF, lock a specific layer on the first page, and save the document with the changes. There are two new methods and one property was added:
Layer.Lock(); - Locks the layer. Layer.Unlock(); - Unlocks the layer. Layer.Locked; - Property, indicating the layer locked state.
Document document = new Document(input);
Page page = document.getPages().get_Item(1);
Layer layer = page.getLayers().get(0);
layer.lock();
document.save(output);
Extract PDF layer elements
The Aspose.PDF for Java library allows extracts of each layer from the first page and saves each layer to a separate file.
To create a new PDF from a layer, the following code snippet can be used:
Document document = new Document(inputPath);
java.util.List<Layer> layers = document.getPages().get_Item(1).getLayers();
for (Layer layer : layers)
{
layer.save(outputPath);
}
Flatten a layered PDF
Aspose.PDF for Java library opens a PDF, iterates through each layer on the first page, and flattens each layer, making it permanent on the page.
Document document = new Document(input);
Page page = document.getPages().get_Item(1);
for (Layer layer : page.getLayers())
{
layer.flatten(true);
}
document.save(output);
The Layer.flatten(boolean cleanupContentStream) method accepts the boolean parameter that specifies whether to remove optional content group markers from the content stream. Setting the cleanupContentStream parameter to false speeds up the process of flattening.
Merge All Layers inside the PDF into one
The Aspose.PDF for Java library allows merges either all PDF layers or a specific layer on the first page into a new layer and saves the updated document.
Two methods were added to merge all layers on the page:
- void mergeLayers(String newLayerName);
- void mergeLayers(String newLayerName, String newOptionalContentGroupId);
The second parameter allows renaming the optional content group marker. The default value is “oc1” (/OC /oc1 BDC).
Document document = new Document(input);
Page page = document.getPages().get_Item(1);
page.mergeLayers("NewLayerName");
// Or page.mergeLayers("NewLayerName", "OC1");
document.save(output);
What’s new in Aspose.PDF 24.4
This release introduced Java plugins for PDF:
- Form Flattener Plugin
FormFlattener pdfFormPlugin = new FormFlattener();
FormFlattenAllFieldsOptions opt = new FormFlattenAllFieldsOptions();
opt.addInput(new FileDataSource("sample.pdf"));
opt.addOutput(new FileDataSource("sample-flat.pdf"));
ResultContainer result = pdfFormPlugin.process(opt);
// Check result.
java.util.List < IOperationResult > resultCollectionInternal = result.getResultCollection();
- Form Exporter
Rectangle rect = new com.aspose.pdf.Rectangle(0, 220, 600, 330);
// Plugin use.
FormExporter pdfFormPlugin = new FormExporter();
SelectField selectField = new SelectField() {
public boolean invoke(Field field) {
return field instanceof TextBoxField && field.getPageIndex() == 2 && rect.isInclude(field.getRect(), 0);
}
};
FormExporterValuesToCsvOptions opt = new FormExporterValuesToCsvOptions(selectField, ';');
opt.addInput(new FileDataSource(inputFileNameWithFields));
opt.addInput(new FileDataSource(getInputPath("document-1.pdf")));
opt.addInput(new FileDataSource(getInputPath("document-2.pdf")));
opt.addInput(new FileDataSource(getInputPath("document-3.pdf")));
opt.addOutput(new FileDataSource(getOutputPath("out.csv")));
ResultContainer result = pdfFormPlugin.process(opt);
// Check result.
System.out.println(result.getResultCollectionInternal().size() > 0);
System.out.println(result.getResultCollectionInternal().get_Item(0).isFile());
System.out.println(result.getResultCollectionInternal().get_Item(0).getData().toString());
- Merger Plugin
String input1 = "sample.pdf";
String input2 = "sample.pdf";
String output = "TestMergeFileAndStream_ResultAsFile.pdf";
Merger merger = new Merger();
MergeOptions opt = new MergeOptions();
opt.addInput(new FileDataSource(input1));

What’s new in Aspose.PDF 24.3
From 24.3 implement a search through a list of phrases in a TextFragmentAbsorber.
String[] expressions = new String[] {
//detect phone number
"\\b\\d{3}-\\d{3}-\\d{4}\\b",
//detect card number
"\\b(?:\\d[ -]*?){13,16}\\b"
};
Document document = new Document(input);
TextFragmentCollection newTextFragmentCollection = new TextFragmentCollection();
Pattern[] regexes = new Pattern[6];
for (int i = 0; i < expressions.length; i++) {
regexes[i] = Pattern.compile(expressions[i], Pattern.CASE_INSENSITIVE);
}
TextFragmentAbsorber newAbsorber = new TextFragmentAbsorber(regexes, new TextSearchOptions(true));
document.getPages().accept(newAbsorber);
HashMap < Pattern, TextFragmentCollection > map = newAbsorber.getRegexResults();
Next feature is adding the ability to convert tables for the PDF to Markdown converter
Document doc = new Document(dataDir + "56201.pdf");
MarkdownSaveOptions saveOptions = new MarkdownSaveOptions();
doc.save(dataDir + "56201.md", saveOptions);
What’s new in Aspose.PDF 24.2
From 24.2 possible to add the Watermark in PDF with AcroForms. TextStamp is suitable for use with AcroForm files. If you use TextStamp for XFA files, the text is drawn on the page as in a usual PDF file (it can be seen in those PDF viewers that cannot read XFA files, for example, in a Chrome browser). To add text to the XFA file, it must be changed in the XFA file’s internal XML.
String sourceName = dataDir + "551.3xfa.pdf";
String targetName = dataDir + "output_2_" + BuildVersionInfo.AssemblyVersion + ".pdf";
Document pdfDocument = new Document(sourceName);
XFA xfa = pdfDocument.getForm().getXFA();
String watermark =
"<subform>" +
"<draw rotate=\"90\" x=\"100px\" y=\"100px\">" +
"<value>" +
"<text>Sample Stamp</text>\n" +
"</value>" +
"<font typeface=\"Arial\" size=\"14px\" weight=\"bold\" posture=\"italic\">" +
"<fill>" +
"<color value=\"0,128,0\"/>" +
"</fill>" +
"</font>" +
"</draw>" +
"</subform>";
xfa.appendToTemplate("//tpl:pageArea", watermark);
pdfDocument.save(targetName);
pdfDocument.close();
Set StateModel for Annotation We can use setReviewState and setMarkedState from MarkupAnnotation class to set needed state. All markup annotations have a Set State option available.
// Open the source PDF document
Document pdfDocument = new Document();
pdfDocument.getPages().add();
// Create annotation
TextAnnotation textAnnotation = new TextAnnotation(pdfDocument.getPages().get_Item(1), new Rectangle(200,
400, 400, 600));
//Set annotation title
textAnnotation.setTitle("Sample Annotation Title");
//Set annotation subject
textAnnotation.setSubject("Sample Subject");
//Specify the annotation contents
textAnnotation.setContents("Sample contents for the annotation");
textAnnotation.setOpen(true);
textAnnotation.setIcon(TextIcon.Key);
com.aspose.pdf.Border border = new com.aspose.pdf.Border(textAnnotation);
border.setWidth(5);
border.setDash(new Dash(1, 1));
textAnnotation.setBorder(border);
String userName1 = "Aspose1";
textAnnotation.setReviewState(AnnotationState.Rejected, userName1);
textAnnotation.setRect(new Rectangle(200, 400, 400, 600));
//Add annotation in the annotations collection of the page
pdfDocument.getPages().get_Item(1).getAnnotations().add(textAnnotation);
pdfDocument.processParagraphs();
//Save the output file
pdfDocument.save(dataDir + "output_24_2_Rejected.pdf");
pdfDocument = new Document(dataDir + "output" + version + "3.pdf");
TextAnnotation textAnnotation2 = (TextAnnotation) pdfDocument.getPages().get_Item(1).getAnnotations().get_Item(1);
String userName2 = "Aspose2";
textAnnotation2.setReviewState(AnnotationState.Accepted, userName2);
pdfDocument.save(dataDir + "output_24_2_Rejected_and_Accepted.pdf");
From 24.2 implement OFD to PDF conversion:
Document document = new Document(inputPath, new OfdLoadOptions());

What’s new in Aspose.PDF 23.12
The form can be found and the text can be replaced using the following code snippet:
Document document = new Document(input);
String expectedText = "This is a text added while creating new PDF in Kofx Power PDF Standard.";
XFormCollection forms = document.getPages().get_Item(1).getResources().getForms();
Iterator tmp0 = (forms).iterator();
while (tmp0.hasNext()) {
XForm form = (XForm) tmp0.next();
if ("Typewriter".equals(form.getIT()) && "Form".equals(form.getSubtype())) {
TextFragmentAbsorber absorber = new TextFragmentAbsorber();
absorber.visit(form);
Iterator tmp1 = (absorber.getTextFragments()).iterator();
while (tmp1.hasNext()) {
TextFragment fragment = (TextFragment) tmp1.next();
fragment.setText("");
}
}
}
document.save(output);
Or, the form can be completely removed:
Document document = new Document(input);
XFormCollection forms = document.getPages().get_Item(1).getResources().getForms();
//foreach to while statements conversion
Iterator tmp0 = (forms).iterator();
while (tmp0.hasNext()) {
XForm form = (XForm) tmp0.next();
if ("Typewriter".equals(form.getIT()) && "Form".equals(form.getSubtype())) {
String name = forms.getFormName(form);
forms.delete(name);
}
}
document.save(output);
Another variant of removing the form:
Document document = new Document(input);
XFormCollection forms = document.getPages().get_Item(1).getResources().getForms();
for (int i = 1; i <= forms.size(); i++) {
if ("Typewriter".equals(forms.get_Item(i).getIT()) && "Form".equals(forms.get_Item(i).getSubtype())) {
forms.delete(forms.get_Item(i).getName());
}
}
document.save(output);
- All forms can be deleted using the following code snippet:
Document document = new Document(input);
XFormCollection forms = document.getPages().get_Item(1).getResources().getForms();
forms.clear();
document.save(output);
What’s new in Aspose.PDF 23.11
From this release possible to remove hidden text from PDF file:

}
}
document.save(outputFile);
What’s new in Aspose.PDF 23.10
The current update presents three versions of Removing tags from tagged PDFs.
- Remove some node element from a documentElement (root tree element):
Document document = new Document(inputPath);
RootElement structure = document.getLogicalStructure();
Element documentElement = structure.getChildren().get_Item(0);
Element structElement = (documentElement.getChildren().getCount() > 1) ? documentElement.getChildren().get_Item(1) : null;
documentElement.getChildren().remove(structElement);
// You can also delete the structElement itself
//if (structElement != null)
//{
// structElement.remove();
//}
document.save(outputPath);
- Remove all marked elements tags from the document, but keep the structure elements:
Document document = new Document(inputPath);
RootElement structure = document.getLogicalStructure();
Element root= structure.getChildren().get_Item(0);
Queue<Element> queue = new ArrayDeque<Element>();
queue.add(root);
for (Element element : structure.getChildren() ) {
queue.add(element);
for (Element child : element.getChildren())
{
queue.add(child);
}
}
for (Element element:queue ) {
if (element instanceof TextElement || element instanceof FigureElement)
element.remove();
}
document.save(outputPath);
- Remove tags at all:
Document document = new Document(inputPath);
RootElement structure = document.getLogicalStructure();
Element root = structure.getChildren().get_Item(0);
root.remove();
document.save(outputPath);
We’ve implemented a new feature to measure character height. Use the following code to measure the height of a character:
Document doc = new Document("input.pdf");
TextFragmentAbsorber absorber = new TextFragmentAbsorber();
absorber.visit(doc.getPages().get_Item(1));
double height = absorber.getTextFragments().get_Item(1).getTextState().measureHeight('h')
Note that the measurement is based on the font embedded in the document. If any information for a dimension is missing, this method returns 0.
What’s new in Aspose.PDF 23.9
From 23.9 support to remove a child annotation from a fillable field.
example 1:
String input = "55343_1.pdf";
Document doc = new Document(input);
final String fieldName = "1 Vehicle Identification Number";
Field field = (Field) doc.getForm().get_Item(fieldName);
System.out.println(0 == field.size());
Rectangle rect = field.getRect();
doc.getForm().addFieldAppearance(field, 2, rect);
System.out.println(2 == field.size());
field = (Field) doc.getForm().get_Item(fieldName);
System.out.println(2 == field.size());
doc.getForm().removeFieldAppearance(field, 1);
System.out.println(0 == field.size());
field = (Field) doc.getForm().get_Item(fieldName);
System.out.println(0 == field.size());
example 2:

document.save(getOutputPath("55157.pdf"));
stream.close();
What’s new in Aspose.PDF 23.8
The function for detecting Incremental Updates in a PDF document has been added in 23.8. This function returns ’true’ where document was saved with incremental updates, otherwise, it returns ‘false’.
Document doc = new Document(dataDir+"PDF_Support_Tech_Note.pdf");
boolean not_updatedIncrementally = doc.hasIncrementalUpdate();
System.out.println(not_updatedIncrementally);
doc.getPages().add();
doc.saveIncrementally(dataDir+"PDF_updatedIncrementally.pdf");
doc = new Document(dataDir+"PDF_updatedIncrementally.pdf");
boolean updatedIncrementally = doc.hasIncrementalUpdate();
System.out.println(updatedIncrementally);
doc.close();
One more feature is Copy OutputIntents from input PDF to destination PDF
We add a new public property Document.getOutputIntents() to allow access to output intents in a document. For a time being only the usage of already existing in some document output intents is supported, user can’t create OutputIntent from scratch.
Document document1 = new Document(dataDir+"pdfa.pdf");
Document resultDocument = new Document();
resultDocument.getPages().add(document1.getPages());
for (OutputIntent intent : document1.getOutputIntents())
{
resultDocument.getOutputIntents().addItem(intent);

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();
