LinearizationParams

Vue de l’ensemble

‘LinearizationParams’ est une classe dans Aspose.PDF FOSS pour Java.

Il représente le dictionnaire des paramètres de la linéarisation (Table F.1, ISO 32000-1:2008).

Cette classe fournit 21 méthodes pour travailler avec les objets de LinearizationParams dans des programmes Java. Les méthodologies disponibles comprennent: ‘detect’, ‘getEndOfFirstPage’, getFileLength', ‘getPirtPagesNumber’, ' getFirePagObjNom', ’getHintStreamLongth’, ‘ghetHentStreemOffset’, getsNutPags’, ‚getNunPays‘, ‘GetVersion, isValid` , ‘parse’ et 9 méthode supplémentaires. Tous les membres publics sont accessibles à toute application Java après l’installation de l’Aspose.PDF FOSS pour le package Java . Propriétés : ‘OffirPayer’, ‘‘Lang’‘first, ‘‘NitPyng’n’Nim’Ling’Sett, plus 3M’Stamper’Stratm, et plus.

Propriétés

Name	Type	Access	Description
`version`	`double`	Read	Returns the linearization version (always 1.0).
`fileLength`	`long`	Read	Returns the total file length (/L).
`hintStreamOffset`	`long`	Read	Returns the primary hint stream byte offset (/H[0]).
`hintStreamLength`	`int`	Read	Returns the primary hint stream length (/H[1]).
`firstPageObjNum`	`int`	Read	Returns the first page’s page object number (/O).
`endOfFirstPage`	`long`	Read	Returns the offset of end of first page section (/E).
`numPages`	`int`	Read	Returns the number of pages (/N).
`mainXRefOffset`	`long`	Read	Returns the offset of the main xref table (/T).
`firstPageNumber`	`int`	Read	Returns the first page number (/P), default 0.

méthodes

Signature	Description
`parse(dict: PdfDictionary)` → `LinearizationParams`	Parses linearization parameters from a PdfDictionary.
`toDictionary()` → `PdfDictionary`	Writes this linearization parameter dictionary as a PDF dictionary.
`detect(reader: RandomAccessReader)` → `LinearizationParams`	Detects whether a PDF is linearized by scanning the first 1024 bytes
for a linearization parameter dictionary.
`getVersion()` → `double`	Returns the linearization version (always 1.0).
`getFileLength()` → `long`	Returns the total file length (/L).
`setFileLength(fileLength: long)`	Sets the file length value.
`getHintStreamOffset()` → `long`	Returns the primary hint stream byte offset (/H[0]).
`setHintStreamOffset(offset: long)`	Sets the hint stream offset value.
`getHintStreamLength()` → `int`	Returns the primary hint stream length (/H[1]).
`setHintStreamLength(length: int)`	Sets the hint stream length value.
`getFirstPageObjNum()` → `int`	Returns the first page’s page object number (/O).
`setFirstPageObjNum(num: int)`	Sets the first page obj num value.
`getEndOfFirstPage()` → `long`	Returns the offset of end of first page section (/E).
`setEndOfFirstPage(offset: long)`	Sets the end of first page value.
`getNumPages()` → `int`	Returns the number of pages (/N).
`setNumPages(n: int)`	Sets the num pages value.
`getMainXRefOffset()` → `long`	Returns the offset of the main xref table (/T).
