Class PDFParser

java.lang.Object

org.apache.tika.parser.AbstractParser

org.apache.tika.parser.pdf.PDFParser

All Implemented Interfaces:

Serializable, org.apache.tika.parser.Parser

public class PDFParser
extends org.apache.tika.parser.AbstractParser

PDF parser.

This parser can process also encrypted PDF documents if the required password is given as a part of the input metadata associated with a document. If no password is given, then this parser will try decrypting the document using the empty password that's often used with PDFs. If the PDF contains any embedded documents (for example as part of a PDF package) then this parser will use the EmbeddedDocumentExtractor to handle them.

As of Tika 1.6, it is possible to extract inline images with the EmbeddedDocumentExtractor as if they were regular attachments. By default, this feature is turned off because of the potentially enormous number and size of inline images. To turn this feature on, see PDFParserConfig.setExtractInlineImages(boolean).

getSupportedTypes

public Set<org.apache.tika.mime.MediaType> getSupportedTypes(org.apache.tika.parser.ParseContext context)

getPDFParserConfig

public PDFParserConfig getPDFParserConfig()

setPDFParserConfig

public void setPDFParserConfig(PDFParserConfig config)

getEnableAutoSpace

public boolean getEnableAutoSpace()

Deprecated. use getPDFParserConfig()

See Also:

setEnableAutoSpace(boolean)

setEnableAutoSpace

public void setEnableAutoSpace(boolean v)

Deprecated. use setPDFParserConfig(PDFParserConfig)

If true (the default), the parser should estimate where spaces should be inserted between words. For many PDFs this is necessary as they do not include explicit whitespace characters.

getExtractAnnotationText

public boolean getExtractAnnotationText()

Deprecated. use getPDFParserConfig()

If true, text in annotations will be extracted.

setExtractAnnotationText

public void setExtractAnnotationText(boolean v)

Deprecated. use setPDFParserConfig(PDFParserConfig)

If true (the default), text in annotations will be extracted.

getSuppressDuplicateOverlappingText

public boolean getSuppressDuplicateOverlappingText()

Deprecated. use getPDFParserConfig()

See Also:

setSuppressDuplicateOverlappingText(boolean)

setSuppressDuplicateOverlappingText

public void setSuppressDuplicateOverlappingText(boolean v)

Deprecated. use setPDFParserConfig(PDFParserConfig)

If true, the parser should try to remove duplicated text over the same region. This is needed for some PDFs that achieve bolding by re-writing the same text in the same area. Note that this can slow down extraction substantially (PDFBOX-956) and sometimes remove characters that were not in fact duplicated (PDFBOX-1155). By default this is disabled.

getSortByPosition

public boolean getSortByPosition()

Deprecated. use getPDFParserConfig()

See Also:

setSortByPosition(boolean)

setSortByPosition

@Field
public void setSortByPosition(boolean v)

Deprecated. use setPDFParserConfig(PDFParserConfig)

If true, sort text tokens by their x/y position before extracting text. This may be necessary for some PDFs (if the text tokens are not rendered "in order"), while for other PDFs it can produce the wrong result (for example if there are 2 columns, the text will be interleaved). Default is false.

setOcrStrategy

@Field
public void setOcrStrategy(String ocrStrategyString)

setOcrImageType

@Field
public void setOcrImageType(String imageType)
