Synchronous conversion of HTML to PDF

You can convert a string of HTML or a URL to a PDF. The config.setDocument(String) method can be either a String of HTML or a URL to a page that you want converted. If you are converted a page that requires Basic authentication, you can set the authentication headers for the request with setAuthenticationCredentials().

java

import com.realobjects.pdfreactor.webservice.client.Configuration;
import com.realobjects.pdfreactor.webservice.client.PDFreactor;
import com.realobjects.pdfreactor.webservice.client.Result;

private static byte[] convertHtml() throws IOException {
    //Your HTML to be converted
    String html = "<html><head><title>My document</title></head><body><h1>Foo bar</h1><p>Lorem Ipsum!</p></body></html>";

    //Create the PDFreactor instance
    PDFreactor pdfReactor = new PDFreactor("https://pdf.ais.its.uiowa.edu/service/rest");
    pdfReactor.setApiKey("my-super-secure-api-key");

    //Network settings for timeouts, etc.
    Configuration.NetworkSettings networkSettings = new Configuration.NetworkSettings();
    networkSettings.setConnectTimeout(2000); //timeout waiting for css/js/images to download

    //Basic configuration
    Configuration config = new Configuration();
    config.setDocument(html);
    config.setDocumentDefaultLanguage("en-US"); //The document language improves accessibility
    config.setNetworkSettings(networkSettings);
    config.setTitle("The University of Iowa"); //A title is required for accessibility
    config.setConformance(Configuration.Conformance.PDFUA1); //This sets the conformance to be accessible 

    //Do the conversion
    try {
        Result result = pdfReactor.convert(config);
        if (result != null) {
            return result.getDocument();
        }
    } catch (Exception e) {
        log.error("PDF service returned error: " + e.getMessage(), e);
        throw new IOException("PDF Service returned a failure.");
    }
}

Converting HTML to an image

PDFreactor is also capable of converting HTML to an image. This might be useful if you need to automatically generate a screenshot of a page. You can output to a PNG (optional transparent background) GIF, JPEG, TIFF, or BMP. The Image Output documentation contains more details and options.

java

import com.realobjects.pdfreactor.webservice.client.Configuration;
import com.realobjects.pdfreactor.webservice.client.PDFreactor;
import com.realobjects.pdfreactor.webservice.client.Result;

private static byte[] convertHtml() throws IOException {
    //Your HTML to be converted
    String html = "<html><head><title>My document</title></head><body><h1>Foo bar</h1><p>Lorem Ipsum!</p></body></html>";

    //Create the PDFreactor instance
    PDFreactor pdfReactor = new PDFreactor("https://pdf.ais.its.uiowa.edu/service/rest");
    pdfReactor.setApiKey("my-super-secure-api-key");

    //Network settings for timeouts, etc.
    Configuration.NetworkSettings networkSettings = new Configuration.NetworkSettings();
    networkSettings.setConnectTimeout(2000); //timeout waiting for css/js/images to download

    //Basic configuration
    Configuration config = new Configuration();
    config.setDocument(html);
    config.setNetworkSettings(networkSettings);
    config.setOutputFormat(new OutputFormat()
            .setType(OutputType.PNG)
            .setWidth(512) //Give it a width
            .setHeight(-1)); //-1 means use proportional scaling

    //Do the conversion
    try {
        Result result = pdfReactor.convert(config);
        if (result != null) {
            return result.getDocument();
        }
    } catch (Exception e) {
        log.error("PDF service returned error: " + e.getMessage(), e);
        throw new IOException("PDF Service returned a failure.");
    }
}
