An HTML to PDF library for the JVM. Based on Flying Saucer and Apache PDF-BOX 2. With SVG image support. Now also with accessible PDF support (WCAG, Section 508, PDF/UA)!

Last update: Dec 29, 2022

Overview

OPEN HTML TO PDF

OVERVIEW

Open HTML to PDF is a pure-Java library for rendering arbitrary well-formed XML/XHTML (and even HTML5) using CSS 2.1 for layout and formatting, outputting to PDF or images.

Use this library to generated nice looking PDF documents. But be aware that you can not throw modern HTML5+ at this engine and expect a great result. You must special craft the HTML document for this library and use it's extended CSS feature like #31 or #32 to get good results. Avoid floats near page breaks and use table layouts.

0.0.1-RC20 (2019-April-26)

IMPORTANT: This release was brought forward due to a CVE in PDFBOX. While not directly affecting this project (it affects parsing of untrusted PDFs), it is better not to have a vulnerable library on your classpath.

0.0.1-RC19 (2019-March-18)

#336 Fix for broken image links causing an NPE. Thanks @svenfrauen.
#334 Allow the user to supply PDPage objects via page supplier. Thanks @DSW-PS.

0.0.1-RC18 (2019-March-10)

Please start using the fast renderer (builder.useFastMode()) as the old renderer will be removed in a future version.
#180 Fast renderer is finally ready for production. The fast renderer comes with:
- Nearly 150 automated end-to-end regression tests. This is about 150 more than the old renderer.
- Improved performance. This renderer scales linearly with the number of pages, compared to the old renderer which scaled with the page count squared.
- Far better support for transforms, including nested transforms, multiple transforms and transforms interacting with hidden overflow, etc.
- Better support for hidden overflow, with boxes now not escaping except with accordance to the standard.
- Support for inserted cut off overflow pages. See Cut-off page support on the wiki.
- Link areas and their hash link targets now repect transforms.
- Bookmark targets now respect transforms.
- Improved page placement for boxes. Now respects overflow and tranform properties.
- Greater understanding which should make fixes and feature improvements easier.
Visual testing API is now available to use in the PDFBOX module. Please see testing your PDF on the wiki. Thanks @red6.
#333 Upgraded PDFBox to 2.0.14 and PDFBox-Graphics2D to 0.21.
#315, #79 Accessible and tagged PDF support. See PDF Accessibility (PDF UA, WCAG, Section 508) Support on the wiki.
#326 Proper support for PDF/A standards with automatic regression testing. See PDF/A Standards Compliance on the wiki.
#328 SVG with page rule was crashing in certain circumstances.
#324 Better logging with invalid or missing fonts.
#320 NPE prevention in case of incorrect font configuration.
a145329 Were using incorrect font-metrics in certain situations.
#303 Fixed: Table borders are partly transparent.
#297 Fixed: Border not printed with "overflow: hidden".
#304 Fix warnings for icon font without space inside PDF/A, add tests.
#301 Make loading resources from classpath work when openhtmltopdf is a named module.
#232 Were using JRE internal APIs.
#289 System.out.println("Getting image") in NaiveUserAgent.

Base 64 encoded Image does not load in pdf

Hi,

I have a Base 64 encoded image in my html file. The image I need to have in the pdf. But I get error like

com.openhtmltopdf.exception WARNING:: When trying to load uri(data:image/png .....) com.openhtmltopdf.load INFO:: URI resolver rejected loading image at (data:image/png ....)

If Base 64 image is not supported yet, can you please let me know how an image can be converted from html to pdf.

Large HTML File conversion to PDF hangs.

Hi,

I am trying to convert large HTML File approximately 600 pages which is not passing the conversion and hangs.

Following is my observation after debugging the core. PdfRendererBuilder.class file has following method call.

renderer.layout(); // This action takes significant time but completes the process. 2. renderer.createPDF(); // This action is not completing its execution and hangs the process.

when I looked into it renderer.createPDF() is trying to create entire PDF in memory (document) and after completion it starts writing to OutputStream.

Can we write it directly to OutputStream page by page? I think this might solve the problem.

Following is my code snippet please check the same if I am doing anything wrong here.

public void exportToPdf(List<Map<String, Object>> data, String template, Map<String, Object> exportData,
            Configuration cfg, String pdfURL) throws Exception   {

            }
        }
    }

In above code snippet it is not completing builder.run(); process and hangs.

Please help me with the solution.

Thanks in advance.

Thread is stuck during HTML to PDF conversion with nested tables for fairly large HTML

Update 9/23/20: The first two HTML files I attached are misleading and work as expected. I found that the problem is actually occurring only when the height/max-height of the div enclosing the table is set to "auto":

@syjer Try this new HTML file attached, it should reproduce the issue for you as well. Sorry about the confusion with the previous test cases. FYI running this in my minimal test application using this HTML file was 90,087ms which is consistent with the results I see inside of my program. smaller_test_auto_height.txt

Original Issue/info below, the stack trace thread dump info applies to the "smaller_test_auto_height.txt" test case since my proram was using this "auto" height all along (which I wasn't aware of ?? ):

Currently our HTML target is email, so we are using a lot of HTML table elements, nested and everything is inline styles. I suspect that I have a thread hanging due to the nested tables. Unfortunately I'm not sure what I can do to work around this issue. I've tried "table-layout: fixed" and assigning column widths as well.

Update: made sure that it is valid XHTML as well using https://validator.w3.org/: problem_html1.txt

Here is also a smaller test html that is still painfully slow (~1.5-2 minutes). It is the same content, just reduced the number of table rows to 71 for easier visibility: smaller_test.txt

If I enable logging I see infinite messages as follow:

com.openhtmltopdf.cascade FINEST:: min-height, relative= 0.0 (0), absolute= 0.0 using base=460.0

...

Question is -- what exactly is the issue and what can I do to work around this if I am pretty much stuck with the current layout? It may not be feasible to get rid of the table nesting.

Probably this Exception#printStackTrace call should be removed, although I don't understand how can font be null:

public void close() {
		for (FontDescription fontDescription : _fontCache.values()) {
			/*
			 * If the font is not yet subset, we must subset it, otherwise we may leak a
			 * file handle because the PDType0Font may still have the font file open.
			 */
			if (fontDescription._font != null && fontDescription._font.willBeSubset()) {
				try {
					fontDescription._font.subset();
				} catch (IOException e) {
					e.printStackTrace();
				}
			}
		}
		_fontCache.clear();

		// Close all still open TrueTypeCollections
		for (TrueTypeCollection collection : _collectionsToClose) {
			try {
				collection.close();
			} catch (IOException e) {
				e.printStackTrace();
			}
		}
		_collectionsToClose.clear();

Object Renderer link placement

As outcome of #475 I am now rendering a tree graph using a custom object renderer based on Graphics2D. but I am now having extreme difficulties to getting the hyperlink boxes for the nodes in my graph correctly, which link to description pages in my document. By seeing where the mouspointer turns into a finger icon in Acrobat Reader I can see, that all link shapes seem to cover almost the whole region covered by the object. It does not matter, where I klick, it opens the same link, so this single link covers the whole region.

The display itself works fine and I am able to scale the graph to fit it in the page width. The graph consists of nodes connected by arrows. Each node is built from a Swing JPanel that lays out JLabels for Node ID, title, node information and outgoing edge ports using GridBagLayout. The nodes themselves are organized in a large JPanel using two nested GridBagLayouts. Again positioning works great and using SwingUtilities.convertRectangle I am able to determine the exact position relative to the main panel of each Title and NodeID label that is supposed to carry a link.

To collect the link shapes, I have extended the JLabel Component with an Interface that provides the url. So during rendering in the custom object drawer, I am able to collect all linked components after layout completes, calculate their bounding shapes relative to the Graphics 2D and create the link map, with shapes as keys and urls as values.

I have verified that the positions of the collected shapes match the drawn Ids and titles by drawing them as red boxes at the end of graph drawing. The cover exactly the areas that are supposed to be the hotspots of the links. But if I return the shape-to-url map and let opengtmltopdf even render just the firdt link, its hotspot covers almost the whole page, instead of the title it is supposed to cover.

I have tried several corrective transformations, even transforms I would expect to result in an extremely small region in the upper left corner on the page, but it does not change anything. It is still the whole region reacting to the click.

Since it does not seem to matter, how large or small I transform the collected link shapes, I think this is a bug and I do not have a clue, how to get it right.

Cache + URL resolver doesn't work as expected

            builder.useUriResolver(new NaiveUserAgent.DefaultUriResolver() {
                @Override
                public String resolveURI(String baseUri, String uri) {

                    String inClassPath = FsPdfGenerator.localResource(uri);
                    if (null != inClassPath) {
                        logger.info("Loading from classpath: "+uri);
                        java.net.URL url = FsPdfGenerator.class.getResource('/' + inClassPath);
                        if (url != null)
                            return url.toExternalForm();
                    }

                    return super.resolveURI(baseUri, uri);
                }

            });

a very simple test cache implementation

@Singleton
public class SimpleCache implements FSCache {

    private static final Logger logger = LoggerFactory.getLogger(SimpleCache.class);

    public static final int MAX_SIZE = 512;

    private final Map<FSCacheKey, Object> cache = lruCache(MAX_SIZE);

    private static <K,V> Map<K,V> lruCache(final int maxSize) {
        return new LinkedHashMap<K,V>(maxSize*4/3, 0.75f, true) {
            @Override
            protected boolean removeEldestEntry(Map.Entry<K,V> eldest) {
                return size() > maxSize;
            }
        };
    }

    private ReentrantReadWriteLock rwl = new ReentrantReadWriteLock();

    public Object get(FSCacheKey cacheKey) {

        try {
            rwl.readLock().lock();
            Object obj = cache.get(cacheKey);
            if (logger.isDebugEnabled()) {
                logger.debug("Requesting: {} of type: {}, got it: {}", cacheKey.getUri(), cacheKey.getClazz().getName(), (obj != null));
            }
            return obj;
        } finally {
            rwl.readLock().unlock();
        }
    }

    public void put(FSCacheKey cacheKey, Object obj)  {
        try {
            rwl.writeLock().lock();
            if (logger.isDebugEnabled()) {
                logger.debug("Putting: {} of type: {}", cacheKey.getUri(), cacheKey.getClazz().getName());
            }
            cache.put(cacheKey, obj);
        } finally {
            rwl.writeLock().unlock();
        }

    }
}

Another Chinese character issue
Hi there,

I was using the Flying Saucer library before and it all went ok until I upgrade my Spring framework to v5 so that I have to look for a newer library to generate PDF with Chinese in it.

I had read quite a few posts and tried many ways, but still seeing ###. Not sure what is going on. Do I miss any step? Please help.

My css file: @CHARSET "UTF-8"; @font-face { font-family: "Arial Unicode MS"; src: url('arialuni.ttf'); }

{ font-family: "Arial Unicode MS",sans-serif; }

HTML file:
Testing
每星期三
Every Wednesday

Java: public static void main(String[] args) throws Exception { try (OutputStream os = new FileOutputStream("E:/Temp/out.pdf")) { PdfRendererBuilder builder = new PdfRendererBuilder(); // builder.useFont(new File("E:/Temp/arialuni.ttf"),"Arial Unicode MS"); builder.useFastMode(); builder.withUri("file:///E:/Temp/index.html"); builder.toStream(os); builder.run(); } }

Result:

myCode

Seems that the incredibly long line is the problem. After reformatting / pretty printing it, everything is fine. Is this fixable / preventable? An OutOfMemoryError is never nice.

Greetings and thank you for looking into it Joe

Add support for fillable form elements (basic features)
This issues is extended with "basic features", as more advanced features and elements (like drop-downs or definition of text content types) are covered in a separate issue

As in the current flying saucer version, input elements should not only be rendered, but also be created as AcroForm elements in the resulting PDF (note that the implementation in flying saucer has some limitations though - e.g. radioboxes are not yet implemented, and css styles are a bit quirky still). In a first implementation, the following elements should be considered:

HTML <input type="text" name="..." value="..."> : a text form field should be rendered, one line only. If a value is provided in the value attribute, it should be pre-filled with that value. The name attribute should be taken as value for the "name" property of the form field.

HTML <textarea name="..." value="..."> : a multi-line text form field should be rendered. The hight of the form field should be created based on the css style. If no "height" style can be determined from the css, then it should be calculated based on the rows attribute value, multiplied by the line hight and paddings / line spacings. If the <textarea> element has a node child, the form field should be pre-filled with the text content of that child node. The name attribute should be taken as value for the "name" property of the form field.

HTML <input type="radio" name="..." value="..." checked="true"> : a radio form field should be rendered. The value from the _id attribute should be taken as group-id for the radio boxes. The "name" property of the form field should be composed out of the name attribute, extended by a "." and the running number of the element within the group (e.g. if the name is "mysection.myoptions" then the form element name of the first radio button with this name will be "mysection.myoptions.1"). The "option" value of the form element is to be taken directly from the value attribute of the <input> element. The option should be selected by default, if the checked attribute in the <input> element is set respectively.

HTML <input type="checkbox" name="..." value="..."> : a checkbox form field should be created. The name attribute should be taken as value for the "name" property of the form field. The form field value should be taken over from the value property of the <input> element. The checkbox should be checked by default, if the checked attribute in the <input> element is set respectively.

For all the above elements, basic styling for borders (width, color), background-color, inner padding to content and font settings should be applied (for checkboxes and radio buttons, the dot/check sign is rendered in the font-color - so even there it does count)

Border-radius on background-color is ignored

Hey!

issue: Have a element with a background-color and a border-radius, but the radius is not applied. It only works for a border property.

Is this a limitation, is there a work around?

Large document can not pass PDF/A-1A conformance

We are having issues with large documents. It seems that these large documents keep failing PDF/A-1A conformance even after being tagged as PDF/A-1A. We are getting this error -> syntax problem : real value out of range (too high).

Has anyone ever had this type issue before ?

Support for additional structure types for PDF tagging

When checking a document with <code> tags, I noticed that they are just represented as span. There seems to be a matching structure type – I'm not aware whether it might have been a later addition – but I don't see it used in the PdfBoxAccessibilityHelper. Is this the correct place to look? Browsing a bit through the code I don't see how to customize or subclass this. Is there a way to do this?

Ability to ignore HTML attributes

Hello,

I'm using openhtmltopdf to generate PDF pages from a received email. Outlook emails generate an @page CSS selector by default, which breaks PDF formatting. Could there be support for ignoring certain attributes when rendering PDFs?

Many thanks, Josh
