Options are set using the DASetOption call. It is recommended that developers familiarize themselves with all of the options available.
Options may be Local, in which case they only affect the handle for which they are set, or Global, in which case they automatically affect all handles associated with the hDoc and must be set before the call to DAOpenDocument.
While default values are provided, users are encouraged to set all options for a number of reasons. In some cases, the default values were chosen to provide backwards compatibility. In other cases, the default values were chosen arbitrarily from a range of possibilities.
This chapter covers the following types of options:
This section discusses character mapping options.
This option is used in cases where Oracle Outside In cannot determine the character set used to encode the text of an input file. When all other means of determining the file's character set are exhausted, Oracle Outside In will assume that an input document is encoded in the character set specified by this option. This is most often used when reading plain-text files, but may also be used when reading HTML or PDF files. The possible character sets are listed in charsets.h.
When "extended test for text" is enabled (see SCCOPT_FIFLAGS), this option will still apply to plain-text input files that are not identified as EBCDIC or Unicode.
This option supersedes the SCCOPT_FALLBACKFORMAT option for selecting the character set assumed for plain-text files. For backwards compatibility, use of deprecated character-set -related values is still currently supported for SCCOPT_FALLBACKFORMAT, though internally such values will be translated into equivalent values for the SCCOPT_DEFAULTINPUTCHARSET. As a result, if an application were to set both options, the last such value set for either option will be the value that takes effect.

This section discusses input handling options.
This option controls how files are handled when their specific application type cannot be determined. This normally affects all plain-text files, because plain-text files are generally identified by process of elimination, for example, when a file isn't identified as having been created by a known application, it is treated as a plain-text file.
It is recommended that FI_NONE be set to prevent PDF Export from exporting unidentified binary files as though they were text, which could generate many pages of "garbage" output.
This option must be set for an hDoc before any subhandle has been created for that hDoc.
A number of values that were formerly allowed for this option have been deprecated. Specifically, the values that selected specific plain-text character sets are no longer to be used. Instead, applications should use the SCCOPT_DEFAULTINPUTCHARSET option for such functionality.

This option affects how an input file's internal format (application type) is identified when the file is first opened by the Oracle Outside In technology. When the extended test flag is in effect, and an input file is identified as being either 7-bit ASCII, EBCDIC, or Unicode, the file's contents will be interpreted as such by the export process.
The extended test is optional because it requires extra processing and cannot guarantee complete accuracy (which would require the inspection of every single byte in a file to eliminate false positives.)

This option controls the spacing threshold in PDF input documents. Most PDF documents do not have an explicit character denoting a word break. The PDF filter calculates the distance between two characters to determine if they are part of the same word or if there should be a word break inserted. The space between characters is compared to the length of the space character in the current font multiplied by this fraction. If the space between characters is larger, then a word break character is inserted into the text stream. Otherwise, the characters are considered to be part of the same word and no word break is inserted.

This section discusses graphics options.
This option allows the user to specify the output graphics device's resolution in DPI and only applies to images embedded in a PDF whose size is specified in physical units (in/cm). For example, consider a 1" square, 100 DPI graphic that is to be rendered on a 50 DPI device (SCCOPT_GRAPHIC_OUTPUTDPI is set to 50). In this case, the size of the resulting PDF will be 50 x 50 pixels.
In addition, the special #define of SCCGRAPHIC_MAINTAIN_IMAGE_DPI, which is defined as 0, can be used to suppress any dimensional changes to an image. In other words, a 1" square, 100 DPI graphic will be converted to an image that is 100 x 100 pixels in size. This value indicates that the DPI of the output device is not important. It extracts the maximum resolution from the input image with the smallest exported image size.
Setting this option to SCCGRAPHIC_MAINTAIN_IMAGE_DPI may result in the creation of extremely large images. Be aware that there may be limitations in the system running this technology that could result in undesirably large bandwidth consumption or an error message. Additionally, an out of memory error message will be generated if system memory is insufficient to handle a particularly large image.
Also note that the SCCGRAPHIC_MAINTAIN_IMAGE_DPI setting will force the technology to use the DPI settings already present in raster images, but for all other content the resolution used internally by PDF Export will be in effect.
For some output graphic types, there may be a discrepancy between the value set by this option and the DPI value reported by some graphics applications. The discrepancy occurs when the output format uses metric units (DPM, or dots per meter) instead of English units (DPI, or dots per inch). Depending on how the graphics application performs rounding on meters to inches conversions, the DPI value reported may be 1 unit more than expected.

This option determines the method used to size graphics. The developer can choose among three methods, each of which involves some degree of trade off between the quality of the resulting image and speed of conversion.
Using the quick sizing option results in the fastest conversion of color graphics, though the quality of the converted graphic will be somewhat degraded. The smooth sizing option results in a more accurate representation of the original graphic, as it uses anti-aliasing. Antialiased images may appear smoother and can be easier to read, but rendering when this option is set will require additional processing time. The grayscale only option also uses antialiasing, but only for grayscale graphics, and the quick sizing option for any color graphics.
The smooth sizing option does not work on images which have a width or height of more than 4096 pixels.

Normally, the size of pages generated from spreadsheet worksheets and database tables is limited to the size of the page defined by the input document's page size information and how the SCCOPT_USEDOCPAGESETTINGS option is set. If, after scaling is factored in, the resulting image is too large to fit on a single page, it is split up into multiple pages.
The SCCOPT_MAXSSDBPAGEWIDTH and SCCOPT_MAXSSDBPAGEHEIGHT options are used to change the size of a page to match the scaled size of the page being rendered - within limits. The key reason for those limits is that rendering very large pages can easily overwhelm the memory available on the system. When using this feature, a calculation should be made to be sure that the values passed in work within said memory limits. The values for these two options will override the current page dimensions if necessary.
The memory needed may be calculated based on the following:
memory = [max. worksheet/table height (in inches)] x [max. worksheet/table width (in inches)] x [dpi setting]2 x 3 bytes/pixel + a bit extra for the needs of the rest of the conversion
By default, these options are set to the current page dimensions. Users may choose to set only one of the two options if desired. If, for example, only the SCCOPT_MAXSSDBPAGEWIDTH is set, then the height of the page will be based on the normal page height.
When a worksheet or table is larger than the maximum values specified by these options, then the file is rendered on multiple pages, with the requested (larger) page dimensions.
These new options grow the page size (if needed) to match the size of the worksheet or table.
Please see Figure 10-1 for a diagram which clarifies the interactions of all of the options mentioned in this discussion.

This option is used to select the document's page layout information when rendering.
If TRUE, the document's native (or author selected) page margins, paper size, page scaling and page orientation are used when available from the filter.
The values of the SCCOPT_DEFAULTPAGESIZE, SCCOPT_DEFAULTPRINTMARGINS, SCCOPT_SSPRINTGRIDLINES,SCCOPT_SSPRINTHEADINGS, SCCOPT_SSPRINTHEADINGS, SCCOPT_SSPRINTDIRECTION, and SCCOPT_SSPRINTFITTOPAGE options are overridden if this option is set to TRUE and the properties associated with those options are specified in the input document. Additionally, print area and page breaks in spreadsheet documents are ignored unless this option is set to TRUE.
If FALSE, the page margins, size, orientation and scaling are set to specific values rather than those in the native document. The page size is forced to 8 1/2" x 11" in portrait orientation, but this may be changed by setting the SCCOPT_DEFAULTPAGESIZE option. The margins are forced 1" all around, but may be changed by setting the SCCOPT_DEFAULTPRINTMARGINS option. The scaling for the document will be set to 100%, although this may be changed by setting any of the various scaling options.
It should be noted that this option also affects page orientation for both input spreadsheets and word processing documents.

SCCVWNUMBERFORMAT and SCCVWNUMBERFORMAT775 structures
These structures are used to set the SCCID_NUMBERFORMAT option. The fields of the structures allow the developer to control variables related to international support. Please note that the SCCVWNUMBERFORMAT775 structure always assumes 2-digit year data, whereas the SCCVWNUMBERFORMAT structure allows for both 2- and 4-digit year data.
These are C data structures defined in sccvw.h as follows:
typedef struct SCCVWNUMBERFORMAT775tag { VTTCHAR cDecimalSep; VTTCHAR cThousandSep; VTTCHAR cDateSep; VTTCHAR cTimeSep; VTTCHAR szCurrencySymbol[8]; VTTCHAR szAM[8]; VTTCHAR szPM[8]; VTDWORD dwNumBytesAM; VTDWORD dwNumBytesPM; VTWORD wCurrencyPosition; VTWORD wShortDateOrder; } SCCVWNUMBERFORMAT775, * PSCCVWNUMBERFORMAT775; typedef struct SCCVWNUMBERFORMATtag { VTTCHAR cDecimalSep; VTTCHAR cThousandSep; VTTCHAR cDateSep; VTTCHAR cTimeSep; VTTCHAR szCurrencySymbol[8]; VTTCHAR szAM[8]; VTTCHAR szPM[8]; VTDWORD dwNumBytesAM VTDWORD dwNumBytesPM; VTWORD wCurrencyPosition VTWORD wShortDateOrder; VTWORD wShortDateYearDigits; VTWORD wShortDateMonthDigits; VTWORD wShortDateDayDigits; VTWORD wShortDateFlags; } SCCVWNUMBERFORMAT, * PSCCVWNUMBERFORMAT;
Parameters
cDecimalSep: The character used for the decimal separator when formatting currency.
cThousandSep: The character used for the thousands separator when formatting currency.
cDateSep: The character used to separate years, months, and days when formatting dates. This option only works on variable formats. For example, only one of the several date formats in Microsoft Excel is variable.
cTimeSep: The character used to separate hours, minutes, and seconds when formatting times. This option only works on variable formats. For example, only one of the several time formats in Microsoft Excel is variable.
szCurrencySymbol: The string used for the currency symbol when formatting currency.
szAM: The string used to indicate "AM" when formatting times.
szPM: The string used to indicate "PM" when formatting times.
dwNumBytesAM: Number of bytes of the string stored in szAM.
dwNumBytesPM: Number of bytes of the string stored in szPM.
wCurrencyPosition: Flags that indicate the positioning of the currency symbol when formatting currency. Only six specific filters are supported: SOC6, WG2, WK4, WK6, WPW, and VISO.
SCCVW_CURRENCY_LEADS: The currency symbol is placed before the amount.
SCCVW_CURRENCY_TRAILS: The currency symbol is placed after the amount.
SCCVW_CURRENCY_SPACE: A space is placed between the currency and the amount.
SCCVW_CURRENCY_NOSPACE: A space is not placed between the currency and the amount.
wShortDateOrder: Indicates the order used when formatting short dates (numeric dates). This option only works on variable formats. For example, only one of the several date formats in Microsoft Excel is variable. One of the following:
SCCVW_DATEORDER_MDY: Month, Day, Year
SCCVW_DATEORDER_DMY: Day, Month, Year
SCCVW_DATEORDER_YMD: Year, Month, Date
wShortDateYearDigits: This parameter is specific to the SCCVWNUMBERFORMAT structure. This is the number of digits in the year as specified by the Windows registry entry sShortDate. This option only works on variable formats. For example, only one of the several date formats in Microsoft Excel is variable.
wShortDateMonthDigits: This parameter is specific to the SCCVWNUMBERFORMAT structure. This is the number of digits in the month as specified by the Windows registry entry sShortDate.
wShortDateDayDigits: This parameter is specific to the SCCVWNUMBERFORMAT structure. This is the number of digits in the day as specified by the Windows registry entry sShortDate.
wShortDateFlags: This parameter is specific to the SCCVWNUMBERFORMAT structure. It is reserved for internal use.
Linearization is a method by which PDF renderers are able to render pages of the PDF file before the entire document is loaded. Linearized output is both larger and takes longer to produce; this option allows you to produce non-linearized PDF so that the export process will be quicker and result in a smaller output file.

One of these values:
SCCUT_WP_EMAILHEADERSTANDARD: Displays "To," "From," "Subject," "CC," "BCC," "Date Sent," and "Attachments" header fields only. The filter outputs any fields not listed above as hidden fields, so they will not display.
SCCUT_WP_EMAILHEADERNONE: Displays no email header fields.
SCCUT_WP_EMAILHEADERALL: Displays all available email headers.
Default
SCCUT_WP_EMAILHEADERSTANDARD
Along with SCCOPT_MAILHEADERHIDDEN, these options exist to allow the developer fine-grained control over what email headers are rendered. These options modify which email headers are displayed, and are based on the most recent setting of SCCOPT_WPEMAILHEADEROUTPUT. To implement a fully customized set of email headers for display, your code should first set the SCCOPT_WPEMAILHEADEROUTPUT option to select a baseline set of headers, then use these options to selectively add or remove headers from that set.
Setting a header to be visible means that it will be rendered when that header is found in a document of the appropriate type. Selected headers that are not present in the input file will not have any corresponding output created for them (no 'empty' headers will be created). Setting a header to be hidden means that it will not be rendered for the document types specified.

Parameters:
dwHeaderID
Either the ID of a predefined email header field, found in sccca.h (for example SCCCA_MAIL_TO), or an identifer between NONSTANDARD_HEADER_ID_BASE and NONSTANDARD_HEADER_ID_TOP for tracking a user-defined header.
dwSubTypeID
The type(s) of documents in which to either show or hide this header. These can be joined with a bitwise OR operator. Available subtypes are:
SCCUT_MAILTYPE_EMAIL
SCCUT_MAILTYPE_JOURNAL
SCCUT_MAILTYPE_CONTACT
SCCUT_MAILTYPE_NOTE
SCCUT_MAILTYPE_APPOINTMENT
SCCUT_MAILTYPE_TASK
SCCUT_MAILTYPE_POST
SCCUT_MAILTYPE_DISTROLIST
wsMimeHeaderName
A Unicode string containing the value of a user-specified MIME header name. This value is only used when the dwHeaderId field contains a user-defined ID value between NONSTANDARD_HEADER_ID_BASE and NONSTANDARD_HEADER_ID_TOP.
wsMimeHeaderLabel
Unicode string that will be used as the label for a user-defined MIME header. This value is only used for user-defined headers.
Note:
Support for user-defined MIME headers is intended to allow Outside In to selectively display MIME headers that are not included in the predefined set of email headers known to Outside In. It is likely that most developers using Outside In will not need to specify user-defined MIME headers. Knowledge of the particular MIME headers present in the input email files is necessary in order to take advantage of this capability.

Parameters
dwSize: Must be set by the developer to sizeof(SCCVWFONTALIAS).
dwAliasID: ID of the aliasing in the current list of aliases. In PDF Export, the default is that no alias is applied.
dwFlags: The usage of these flags depends on whether this structure is being used with the DASetOption or DAGetOption message. It should be set to one of the following:
SCCVW_FONTALIAS_COUNT (DAGetOption): dwAliasID will be filled with the count of current font aliases for that device.
SCCVW_FONTALIAS_ALIASNAME (DASetOption): The alias of szwAlias for szwOriginal will be used when szwOriginal is not available on the device. When a font alias is added to the list, this can affect the alias count. If an alias already exists for szwOriginal, the new szwAlias will replace it.
SCCVW_FONTALIAS_ALIASNAME (DAGetOption): szwAlias will be filled if there is an alias in the alias list for the font in szwOriginal on that device.
SCCVW_FONTALIAS_GETALIASBYID (DAGetOption): szwAlias and szwOriginal will be filled by the technology for the alias in the numbered slot identified by the ID.
SCCVW_FONTALIAS_GETALIASID (DAGetOption): dwAliasID will be set for the font in szwOriginal. If none exists, the dwAliasID will be 0xFFFFFFF.
SCCVW_FONTALIAS_REMOVEALIASBYID (DASetOption): The alias in that slot will be removed if one exists. When a font alias is removed from the list, this can affect the other alias IDs.
SCCVW_FONTALIAS_REMOVEALIASBYNAME (DASetOption): The alias for the font szwOriginal will be removed from the alias list if one exists. When a font alias is removed from the list, this can affect the other alias IDs.
SCCVW_FONTALIAS_REMOVEALL (DASetOption): The alias list will be cleared out and the count will be zero.
SCCVW_FONTALIAS_USEDEFAULTS (DASetOption): This clears the existing alias list and sets it to a list of default aliases that is variable by platform.
szwOriginal: This represents the original name of a font that will be mapped when this font is not available. This name should be a Unicode string.
szwAlias: This represents the new name of a font that will be used as a replacement for the unmapped font named in szwOriginal. This name should be a Unicode string.

This option is used to stroke out (display as graphical primitives) text in an AutoCAD file. Setting this option to FALSE would improve performance, but the visual fidelity may be compromised.
If the export for the conversion is text only, text is never stroked out.
If the export is not text only, and the drawing is perspective, text will always be stroked out (regardless of this option). This is due to the fact that in non-text only situations visual fidelity is of importance, and handling of textual objects in perspective drawings is more accurate with stroked out text. If the conversion is non-text only and the drawing is not perspective, this option determines if text should be stroked.
Note that when this option is TRUE, some special characters appear as asterisks or question marks due to limited support of characters for stroking out text.

This section discusses callback options.
This is an advanced option that casual users of PDF Export may ignore.
This option is used to disable callbacks being made from PDF Export. Callbacks that are disabled will behave as if they were made and the developer had returned SCCERR_NOTHANDLED.
The option takes a VTDWORD field of flags. When the flag is set, the callback is enabled. By default, all callbacks are enabled. You can activate multiple callbacks by bitwise OR-ing them together. You can also disable multiple callbacks by bitwise &-ing the SCCEX_CALLBACKFLAG_ALLENABLED value with the one's complement of the corresponding callback flags. The following #defines are to be used for enabling the various callbacks:
In addition, the following two special values are available:
SCCEX_CALLBACKFLAG_ALLDISABLED: Disables the receipt of all callbacks. Additionally, bitwise OR-ing this value with one or more flags enables the corresponding callbacks. For example, SCCEX_CALLBACKFLAG_ALTLINK | SCCEX_CALLBACKFLAG_CREATENEWFILE enables the ALTLINK and CREATENEWFILE callbacks, but disables all others.
SCCEX_CALLBACKFLAG_ALLENABLED: Enables the receipt of all callbacks. Additionally, bitwise &-ing this value with the one's complement of one or more flags disables the corresponding callbacks. For example, SCCEX_CALLBACKFLAG_ALLENABLED& (~SCCEX_CALLBACKALTLINK & ~SCCEX_CALLBACKFLAG_CREATENEWFILE) disables the ALTLINK and CREATENEWFILE callbacks, but enables all others.

This option determines the format of strings used in the callback functions. For those structures that contain a field of type BYTE or LPBYTE, a comparable structure has been added which has a similar field of type WORD or LPWORD. These structures will have the same name as the original structure, with the addition of a "W" at the end.
When this option is set to TRUE, any time a callback uses a structure with a string, it will use the new structure. Also, any strings that the callback function returns will be expected to follow the same guidelines. If the option is set to FALSE, all callbacks will use single-byte character strings.
For example, if this option is set to TRUE, and the EX_CALLBACK_ID_CREATENEWFILE callback is called, the pExportData parameter to the callback will point to an EXURLFILEIOCALLBACKDATAW structure. If the option is set to FALSE, the pCommandOrInfoData parameter will point to an EXURLFILEIOCALLBACKDATA structure.

Parameters
dwReadBufferSize: Used to define the number of bytes that will read from disk into memory at any given time. Once the buffer has data, further file reads will proceed within the buffer until the end of the buffer is reached, at which point the buffer will again be filled from the disk. This can lead to performance improvements in many file formats, regardless of the size of the document.
dwMMapBufferSize: Used to define a maximum size that a document can be and use a memory-mapped I/O model. In this situation, the entire file is read from disk into memory and all further I/O is performed on the data in memory. This can lead to significantly improved performance, but note that either the entire file can be read into memory, or it cannot. If both of these buffers are set, then if the file is smaller than the dwMMapBufferSize, the entire file will be read into memory; if not, it will be read in blocks defined by the dwReadBufferSize.
dwTempBufferSize: The maximum size that a temporary file can occupy in memory before being written to disk as a physical file. Storing temporary files in memory can boost performance on archives, files that have embedded objects or attachments. If set to 0, all temporary files will be written to disk.
dwFlags
SCCBUFOPT_SET_READBUFSIZE 1
SCCBUFOPT_SET_MMAPBUFSIZE 2
SCCBUFOPT_SET_TEMPBUFSIZE 4
To set any of the three buffer sizes, set the corresponding flag while calling dwSetOption.
Default
The default settings for these options are:
#define SCCBUFOPT_DEFAULT_READBUFSIZE 2: A 2KB read buffer.
#define SCCBUFOPT_DEFAULT_MMAPBUFSIZE 8192: An 8MB memory-map size.
#define SCCBUFOPT_DEFAULT_TEMPBUFSIZE 2048: A 2MB temp-file limit.
Minimum and maximum sizes for each are:
SCCBUFOPT_MIN_READBUFSIZE 1: Read one Kbyte at a time.
SCCBUFOPT_MIN_MMAPBUFSIZE 0: Don't use memory-mapped input.
SCCBUFOPT_MIN_TEMPBUFSIZE 0: Don't use memory temp files
SCCBUFOPT_MAX_READBUFSIZE 0x003fffff: SCCBUFOPT_MAX_MMAPBUFSIZE 0x003fffff
SCCBUFOPT_MAX_TEMPBUFSIZE 0x003fffff: These maximums correspond to the largest file size possible under the 4GB DWORD limit.
From time to time, the technology needs to create one or more temporary files. This option sets the directory to be used for those files.
It is recommended that this option be set as part of a system to clean up temporary files left behind in the event of abnormal program termination. By using this option with code to delete files older than a predefined time limit, the OEM can help to ensure that the number of temporary files does not grow without limit.

typedef struct SCCUTTEMPDIRSPEC { VTDWORD dwSize; VTDWORD dwSpecType; VTBYTE szTempDirName[SCCUT_FILENAMEMAX]; } SCCUTTEMPDIRSPEC, * LPSCCUTTEMPDIRSPEC;
There is currently a limitation. dwSpecType describes the contents of szTempDirName. Together, dwSpecType and szTempDirName describe the location of the source file. The only dwSpecType values supported at this time are:
IOTYPE_ANSIPATH: Windows only. szTempDirName points to a NULL-terminated full path name using the ANSI character set and FAT 8.3 (Win16) or NTFS (Win32 and Win64) file name conventions.
IOTYPE_UNICODEPATH: Windows only. szTempDirName points to a NULL-terminated full path name using the Unicode character set and NTFS file name conventions. Note that the length of the path name is limited to SCCUT_FILENAMEMAX bytes, or (SCCUT_FILENAMEMAX / 2) double-byte Unicode characters.
IOTYPE_UNIXPATH: UNIX platforms only. szTempDirName points to a NULL-terminated full path name using the system default character set and UNIX path conventions.
Specifically not supported at this time is IOTYPE_REDIRECT.
Users should also note that temporary files created by the technology are not subject to callbacks (such as EX_CALLBACK_ID_CREATENEWFILE) normally made when files are created.
Parameters
dwSize: Set to sizeof(SCCUTTEMPDIRSPEC).
dwSpecType: IOTYPE_ANSIPATH, IOTYPE_UNICODEPATH, or IOTYPE_UNIXPATH
szTempDirName: The path to the directory to use for the temporary files. Note that if all SCCUT_FILENAMEMAX bytes in the buffer are filled, there will not be space left for file names.
Default
The system default directory for temporary files. On UNIX systems, this is the value of environment variable $TMP. On Windows systems, it is the value of environment variable %TMP%.
This option determines the maximum amount of memory that the chunker may use to store the document's data, from 4 MB to 1 GB. The more memory the chunker has available to it, the less often it needs to re-read data from the document.

This option is set when the developer wants to use redirected IO to completely take over responsibility for the low level IO calls of the temp file.
Handle Types
NULL, VTHDOC
Scope
Global (not persistent)
Data Type
VTLPVOID: pCallbackFunc
Function pointer of the redirect IO callback.
Redirect call back function:
typedef { VTDWORD (* REDIRECTTEMPFILECALLBACKPROC) (HIOFILE *phFile, VTVOID *pSpec, VTDWORD dwFileFlags);
There is another option to handle the temp directory, SCCOPT_TEMPDIR. Only one of these two can be set by the developer. The SCCOPT_TEMPDIR option will be ignored if SCCOPT_REDIRECTTEMPFILE is set. These files may be safely deleted when the Close function is called.
