ExtractionOptions (attached to a FileConvertJob) specifies how embedded images and attachments should be handled.

public class ExtractionOptions;

File

ExtractionOptions.java

Remarks

During conversion, embedded images and attachments can be extracted to a folder, with links to the extracted images and attachments inserted in the output.

Example:

        com.dtsearch.engine.FileConverter cj = new com.dtsearch.engine.FileConverter();
    cj.setInputFile(inputFilename);
    cj.setOutputToString(true);
    cj.setOutputFormat(com.dtsearch.engine.OutputFormats.itHTML);

    com.dtsearch.engine.ExtractionOptions exo = new com.dtsearch.engine.ExtractionOptions();
    exo.setOutputLocation("c:\\output");
    exo.setOutputReference("c:\\output");
    // This prevents attachments from being written with executable extensions like .exe or .bat
    exo.setAllowedExtensions("doc docx xls xlsx ppt pptx jpg jpeg png txt zip xml pdf wpd");
    // Attachments with disallowed extensions will have ".data" appended to the filename
    exo.setDefaultExtension("data");
    exo.setFlags(ExtractionOptionsFlags.dtsExoExtractImages |
         ExtractionOptionsFlags.dtsExoExtractAttachments |
         ExtractionOptionsFlags.dtsExoLimitExtensions);
    cj.setExtractionOptions(exo);

    cj.execute();
