Description

uStructSize

Size of this structure, in bytes. Use the sizeof operator to calculate this value.

szFileName

Character string containing the name of the file to save.

pBitmap

Ignored.

nBitsPerPixel

Value that indicates the number of bits per pixel to be used to save the image.

nFormat

Output file format. For valid values, refer to Summary of Supported File Formats.

nQFactor

This parameter is used when saving an image file as FILE_LEAD, FILE_CMP, FILE_PNG, FILE_JPEG, FILE_JPEG_422, FILE_JPEG_411, FILE_EXIF_JPEG_411, FILE_EXIF_JPEG, FILE_FPX_JPEG_QFACTOR, FILE_TIF_JPEG, FILE_TIF_JPEG_422, FILE_TIF_JPEG_411, FILE_JPEG_LAB, FILE_JPEG_LAB_422, FILE_JPEG_LAB_411, FILE_DICOM_JPEG_GRAY, FILE_DICOM_JPEG_COLOR, FILE_DICOM_J2K_GRAY, FILE_TIF_CMP, FILE_TIF_J2K, FILE_TIF_CMW, FILE_RAS_PDF_JPEG, FILE_RAS_PDF_JPEG_422, FILE_RAS_PDF_JPEG_411, FILE_J2K, FILE_JP2, FILE_CMW. Qfactor is a number that determines the degree of loss in the compression process. For possible values, refer to Compression Quality Factors.

uSaveMulti

Data value indicating how to save a page to a multipage file. You can save multipage images in PCX, GIF, FlashPix, and most TIFF file formats (including JTIF, but excluding EXIF). Possible values are:

Value

Meaning

MULTIPAGE_OPERATION_OVERWRITE

[1] Overwrite the file.

MULTIPAGE_OPERATION_APPEND

[2] Append page to the end of the file.

MULTIPAGE_OPERATION_REPLACE

[3] Replace page. Refer to SAVEFILEOPTION.Flags.

MULTIPAGE_OPERATION_INSERT

[4] Insert page. Refer to SAVEFILEOPTION.Flags.

bSaveInterlaced

Flag that indicates whether to save GIF files as interlaced. GIF files may be saved interlaced or non-interlaced. Selecting GIF as the format of the file to be saved, the user is given the option in the dialog of selecting interlaced or non-interlaced. Selecting interlaced will set this flag to TRUE. For more information, see Implementing GIF Features. Possible values are:

Value

Meaning

TRUE

Save GIF files as interlaced.

FALSE

Save GIF files as non-interlaced.

nPasses

Value that indicates the number of passes (scans through the image) when loading or saving a progressive JPEG, LEAD CMP or PNG files. (This value is also used when loading, but not when saving, interlaced PNG files.)

Possible values when saving (whether progressive or not):

Value

Meaning

Any positive number

Save the file as a progressive file with the specified number of passes.

0

Save the file as an ordinary JPEG or LEAD CMP file (not a progressive file).

Any negative number

Save the file as a progressive file with the LEADTOOLS default number of passes.

bSaveWithStamp

Value that indicates the status of the SaveStamp Box. If checked, a stamp of the image will be saved if you called the LDialogBase::EnableAutoProcess and the format supports stamps. Possible values are:

Value

Meaning

TRUE

Save the image with a stamp.

FALSE

Save the image without a stamp.

nStampBits

Value that indicates the bits per pixel of the stamp image to save. A stamp is saved only if the ESO_SAVEWITHSTAMP flag is set in the SAVEFILEOPTION.Flags field, for formats that support stamps. Possible values are 8 or 24.

nStampWidth

Width, in pixels, of the stamp image to save. A stamp is saved only if the ESO_SAVEWITHSTAMP flag is set in the SAVEFILEOPTION.Flags field, in formats that support stamps. Possible values range from 1 to 255.

nStampHeight

Height, in pixels, of the stamp image to save. A stamp is saved only if the ESO_SAVEWITHSTAMP flag is set in the SAVEFILEOPTION.Flags field, in formats that support stamps. Possible values range from 1 to 255.

nPageNumber

Value that indicates the number of the page to replace or the number of the page in front of which to insert the page.

uFileTypeIndex

Value that indicates the file type. When the LDialogFile::DoModalSave function returns, this member will be updated with the file type entered by the user through the dialog. Set this member before calling L_DlgSave to initialize the dialog. For example, to set the initial selection on "LEAD (*.cmp)" format set this member to DLG_FF_SAVE_LEAD. For a list of possible values, refer to Customizing File Format Lists.

uSubTypeIndex

Value that indicates the file sub-type, if one exists. When the LDialogFile::DoModalSave function returns, this member will be updated with the file sub-type entered by the user through the dialog, if one exists. Set this member before calling L_DlgSave to initialize the dialog. For example, to set the initial selection to the "Progressive" subtype of the "LEAD (*.cmp)" file type, set this member to DLG_FF_SAVE_SUB_CMP_PROGRESSIVE. For a list of possible values, refer to Customizing File Format Lists.

FileJ2KOptions

A structure that contains the options to use when saving J2K or JP2 files.

pFileFormats

Pointer to an array of FILESAVEFORMAT structures that will indicate which formats, BPP, and subformats to include in the File Save Dialog. The order of the elements in the array indicates the order the items will appear in the FileType drop-down list box. Pass NULL to have LEADTOOLS add all supported formats, BPP, and subformats to the File Save Dialog. For more information on available file types, refer to Customizing File Format Lists.

uFileFormatsCount

The number of the items in pFileFormats. This member is ignored if pFileFormats is NULL. For more information on available file types, refer to Customizing File Format Lists.

uDlgFlags

User interface flags for this dialog, which determine the layout and action of the dialog. Possible values are:
