The DOCWRTPDFOPTIONS structure provides information about PDF document files.

Members

Options

DOCWRTOPTIONS structure that contains options for a PDF file.

PdfProfile

Value that indicates the type of PDF file will be created. Possible values are:

FontEmbed

Value that indicates the font embedding mode to use when creating a PDF document. Possible values are:

bImageOverText

Flag that indicates whether to create an image over text PDF file. Possible values are:

bLinearized

Flag that indicates whether to create a PDF document that is optimized for fast web viewing. Possible values are:

A linearized PDF file is a file that has been organized in such a way as to enable efficient, incremental access in a network environment.

Linearized PDF files allow the first page of the PDF file to be displayed in a user Web browser before the entire file is downloaded from the Web server.

pwszTitle

Character string that contains the title of the PDF document.

pwszSubject

Character string that contains the subject of the created PDF document.

pwszKeywords

Character string that contains the keywords for the created PDF document.

pwszAuthor

Character string that contains the author of the created PDF document.

bProtected

Flag to indicate whether to create protected (encrypted) PDF document. Possible values are:

pszUserPassword

Character string that contains the user password to be used for opening/reading PDF file.

pszOwnerPassword

Character string that contains the owners password which is used when changing the rights of the PDF document.

EncryptionMode

Value that indicates the encryption level for the PDF document. Possible values are:

bPrintEnabled

Flag that indicates whether to allow/disallow printing for the created PDF document. Possible values are:

bHighQualityPrintEnabled

Flag that indicates whether to enable or disable external viewers and editors to print the resulting PDF document in high quality. This flag is available only for documents created with RC4 128-bit encryption. Possible values are:

bCopyEnabled

Flag that indicates whether to enable or disable external viewers and editors to copy text from the resulting PDF document. Possible values are:

bEditEnabled

Flag indicate whether to enable or disable external viewers and editors to edit the resulting PDF document. Possible values are:

bAnnotationsEnabled

Flag that indicates whether to enable or disable external viewers and editors to add annotations and comments to the resulting PDF document. Possible values are:

bAssemblyEnabled

Flag that indicates whether to enable or disable external viewers and editors to add or remove pages from the resulting PDF document. Possible values are:

OneBitCompression

Value that indicates the one bit image compression types. Possible values are:

ColorImgCompression

Value that indicates the colored image compression types. Possible values are:

nQualityFactor

Number that determines the degree of loss in the compression process. The higher factor the smaller size, this work for JPEG compression only. The default value is 80.

• 0 - Lossless
• 2 - 255 Lossy (2 - Best Quality, 255 - Best Compression)

PdfBookmark

DOCWRTPDFBOOKMARK structure that contains settings for book marking PDF file.

uFlags

Flag that indicates the extra options for writing PDF files. Possible values are:

PageFitType

The page fit type. For possible values, refer to DOCWRTPAGEFITTYPE enumeration.

PageModeType

The page mode type which is specifying how the document should be displayed when it is opened. For possible values, refer to DOCWRTPAGEMODETYPE enumeration.

PageLayoutType

The page layout mode to be used when the document is opened. For possible values, refer to DOCWRTPAGELAYOUTTYPE enumeration.

nInitialPage

The initial page number to be viewed when the PDF document is opened.

dZoomPercent

The initial page zoom percent; 100 equals no zoom. The default value is 0.

dXCoordinate

The horizontal coordinate in points inside initial page to display page at them. Default value is 0.

dYCoordinate

The vertical coordinate in points inside initial page to display page at them. Default value is 0.

bHideToolbar

Flag that indicates whether to hide/show the viewer application’s toolbar when the document is active. Possible values are:

bHideMenubar

Flag that indicates whether to hide/show the viewer application’s menu bar when the document is active. Possible values are:

Comments

pDOCWRTPDFOPTIONS is a pointer to DOCWRTPDFOPTIONS structure. Generally, where a function parameter type is pDOCWRTPDFOPTIONS, you can declare a DOCWRTPDFOPTIONS variable, update the structure's fields, and then pass the variable's address in the parameter. Declaring a pDOCWRTPDFOPTIONS variable is necessary only if your program requires a pointer.

Portable Document Format (PDF). PDF was developed by the Adobe Corporation to allow the exchange and viewing of electronic documents easily and reliably, independent of the environment in which they were created. This format lets you compress large documents to a size small enough to download very quickly. It is also becoming a powerful format for reproducing documents over the web.

The LEADTOOLS Document Writers support creating PDF and PDF/A documents. The following features are supported:

• Unlimited number of pages
• Fully searchable documents
• PDF and PDF/A standards
• Different options for embedding the fonts used in the PDF file, including "all"
• Raster image overlay over the PDF pages. This is used when creating a searchable PDF document that is required to be the same as original final, an image of the original file will be saved over the whole PDF document as an overlay. When using the result document in a PDF viewer, you can still search the text underneath the overlay image while maintaining the look of the original document
• Ecnryption and view options

The Low Level encryption method (40-bit RC4), allows access for some PDF document areas to be restricted. The user may allow/disallow the following for the created PDF document: print document, modify document content, extract text and graphics, modify comments, etc.

The High Level Encryption method (128-bit RC4), allows you to have more restrictions beside the ones of the low level encryption method, so that the user here may allow/disallow printing high resolution and assemble the document.

User password is for opening/reading the PDF file. If you define the user password the resulting PDF file will be encrypted and you have to enter the user password to open it.

Owner password is used for changing the rights of the PDF document. When an owner password protected PDF document is viewed, the owner password is not requested, but it is requested when trying to change something in the password protected PDF file.

Also note that the pszUserPassword, pszOwnerPassword, DOCWRTPDFENCRYPTIONMODE, and Security permissions such as PrintEnabled, bHighQualityPrintEnabled, bCopyEnabled, bEditEnabled, bAnnotationsEnabled and bAssemblyEnabled only have effect if bProtected is TRUE.

Fast web view (Linearization), Security options, and PDF document description options (author, title, subject and keywords) are available only for PDF and they are not supported for PDF/A.

The Bookmarks feature allows for the creation of bookmarks, which can be used to mark parts of a document for quick access. For more information refer to DOCWRTPDFBOOKMARK structure.

Before using the LEADTOOLS Document Writers SDK, unlock it by using the L_SetLicenseFile function. If you want to use the PDF format you must also unlock PDF support with L_SetLicenseFile.

The structure is used by:

• L_DocWriterConvert
• L_DocWriterInit
