### Question:
PDFParser extends AbstractParser implements Initializable { @Field void setExtractInlineImages(boolean extractInlineImages) { defaultConfig.setExtractInlineImages(extractInlineImages); }  Set<MediaType> getSupportedTypes(ParseContext context); void parse(
            InputStream stream, ContentHandler handler,
            Metadata metadata, ParseContext context); PDFParserConfig getPDFParserConfig(); void setPDFParserConfig(PDFParserConfig config); boolean getEnableAutoSpace(); @Field void setEnableAutoSpace(boolean v); boolean getExtractAnnotationText(); void setExtractAnnotationText(boolean v); boolean getSuppressDuplicateOverlappingText(); @Field void setSuppressDuplicateOverlappingText(boolean v); boolean getSortByPosition(); @Field void setSortByPosition(boolean v); @Field void setOcrStrategy(String ocrStrategyString); @Field void setOcrImageType(String imageType); void setInitializableProblemHandler(InitializableProblemHandler initializableProblemHandler); @Field void setDropThreshold(float dropThreshold); @Field void setMaxMainMemoryBytes(long maxMainMemoryBytes); @Override void initialize(Map<String, Param> params); @Override void checkInitialization(InitializableProblemHandler handler); static final String PASSWORD; }### Answer:
@Test public void testEmbeddedJPEG() throws Exception { PDFParserConfig config = new PDFParserConfig(); config.setExtractInlineImages(true); ParseContext context = new ParseContext(); context.set(PDFParserConfig.class, config); List<Metadata> metadataList = getRecursiveMetadata("testPDF_childAttachments.pdf", context); assertEquals(5, metadataList.size()); Metadata jpegMetadata = metadataList.get(1); assertEquals("image/jpeg", jpegMetadata.get(Metadata.CONTENT_TYPE)); assertEquals("1425", jpegMetadata.get(Metadata.IMAGE_LENGTH)); }
