Type

Property name

Description

long

BitsPerPixel

Gets or sets the bits per pixel for the current file type. Changing this property will also change the FileTypeIndex, IsQFactorSupported, IsMultipageSupported and FileSubTypeIndex properties.

BSTR

FileName

Gets or sets the output file name. If the filter is loaded without specifying an output file name, a temporary file name is generated and the user is asked whether to use the temporary filename or not. If the user chooses not to use the temporary file name, the graph will not run.

The user is responsible for freeing the allocated string.

long

FileSubTypeIndex

Gets or sets the current file subtype index. If the current file type has no subtypes, then trying to get or set this property will result in an E_INVALIDARG error.

FileTypeConstants

FileTypeFormat

Gets or sets the current file type format. Changing this value will also change the FileSubTypeIndex property. Generally, any change to this property will affect the following properties: FileTypeIndex, BitsPerPixel, IsQFactorSupported, IsMultipageSupported and FileSubTypeIndex. This property takes one of the enumerated "x-text-underline: normal; /*begin!kadov{{*/ text-decoration: underline; /*}}end!kadov*/ ">FileTypeConstants. The file formats are the same as in the LEADTOOLS Raster Imaging documentation. For a complete list of format types, see "Formats of Output Files" in either the Ltcomn.hlp file or the Ltdlln.hlp file. These files are located in the LEAD/HELP directory, where LEAD represents the directory in which you installed the toolkit.

long

FileTypeIndex

Gets or sets the file type index. Any change in this value will affect the following properties: FileTypeFormat, BitsPerPixel, IsQFactorSupported, IsMultipageSupported, and FileSubTypeIndex.

SaveFileOptions

HandleExistingFile

Gets or sets the option for handling existing files (overwriting options) when saving. For a list of possible values, refer to File Save Options.

SAVE_OPTION_APPLYTOALL can be ORed with the chosen option to apply it to all subsequent cases.

long

InfoFileSubTypeFlags(long lFileTypeIndex);

Read only. Gets the subtype flags for the file type and file subtype at the specified index. For a list of possible values, refer to File Flags. Please note that these values may be combined using OR.

long

InfoFileSubTypeFormat(long lFileTypeIndex);

Read only. Gets the subtype format for the file type and file subtype at the specified index.

long

InfoFileSubTypesCount(long lFileTypeIndex);

Read only. Gets the number of subtypes for the file type at the specified index.

BSTR

InfoFileSubTypeString(long lFileSubTypeIndex)

Read only. Gets the subtype string for the file type and file subtype at the specified index.

The user is responsible for freeing the allocated string.

long

InfoFileTypeBpp(long lIndex)

Read only. Gets the bits per pixel for the file type at the specified index.

BSTR

InfoFileTypeExt(long lIndex)

Read only. Gets the extension string for the file type at the specified index.

The user is responsible for freeing the allocated string.

long

InfoFileTypeFlags(long lIndex)

Read only. Gets the flags for the file type at the specified index. For a list of possible values, refer to File Flags. Please note that these values may be combined using OR.

long

InfoFileTypeFormat(long lIndex)

Read only. Gets the file type format for the specified file type index. The file formats are the same as in the LEADTOOLS Raster Imaging documentation. For a complete list of format types, see "Formats of Output Files" in either the Ltcomn.hlp file or the Ltdlln.hlp file. These files are located in the LEAD/HELP directory, where LEAD represents the directory in which you installed the toolkit.

BSTR

InfoFileTypeString(long lIndex)

Read only. Gets the file type string for the specified file type index.

The user is responsible for freeing the allocated string.

VARIANT_BOOL

InputPinStreamingState

Read only. Retrieves the streaming state of the input pin; VARIANT_TRUE if running and VARIANT_FALSE otherwise.

VARIANT_BOOL

IsMultipageSupported

(Read only) Indicates whether the current file type supports multi-page files.

VARIANT_BOOL

IsQFactorSupported

(Read only) Indicates whether the current file type supports the QFactor for controlling the file compression.

Enables or disables prompting for the file overwrite options. If this property is set to VARIANT_TRUE, a dialog will be shown if the next file name to be used already exists. The dialog will offer the overwrite, skip, and use next available name options in addition to an apply for all option. If this property is set to VARIANT_FALSE, the option in the HandleExistingFile property will be used without asking.

long

QFactor

Gets or sets the QFactor for the current file type format.

VARIANT_BOOL

SaveMultipage

Enables or disables saving to a multi-page file. This will only affect formats that support multi-page files. See also the IsMultipageSupported property.

SaveOptionsCallback

Sets the callback object pointer. For more information, refer to the ILTStlImgWrtUserCallback interface.

long

SupportedFileTypesCount

Read only. Retrieves the number of file types that the filter can save. This can be used to loop through all the supported types getting information such as the string, the bits per pixel, the extension, etc. This can help you build your own user interface.

VARIANT_BOOL

UseTempFileName

Gets or sets a flag that indicates whether to use the temp file name if the user did not set the output file name in the FileName property. If the value is VARIANT_TRUE the filter will create a temp file name and use it. If the value is VARIANT_FALSE the filter will create a temp file and ask the user if he wants to save the frame using the temp file name.

Long
