The SAVEDLGPARAMS structure provides information used to initialize the dialog box created by the L_DlgSave function. After the user closes the dialog box, this structure is updated with information about the user's selections.
| Member | 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 | Pointer to the bitmap handle that references the bitmap used for processing. | |
| 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 Formats of Output Files. | |
| 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 | |
| > 1 | Save the file as a progressive file with the specified number of passes. | |
| 1 |
Save a regular JPEG file with dynamically optimized Huffman tables (ie the Huffman tables are optimized for the image you are saving). Use this for smaller file size (at the expense of speed). |
|
| 0 | Save a regular JPEG file with static Huffman tables (ie the Huffman tables are the same for all images). | |
| < 0 | 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 the DLG_SAVE_AUTOPROCESS flag was set 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 L_DlgSave 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 L_DlgSave 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: | |
| Value | ||
| DLG_SAVE_AUTOPROCESS | ||
| DLG_SAVE_SHOW_CONTEXTHELP | ||
| DLG_SAVE_SHOW_FILEOPTIONS_PROGRESSIVE | ||
| DLG_SAVE_SHOW_FILEOPTIONS_MULTIPAGE | ||
| DLG_SAVE_SHOW_FILEOPTIONS_STAMP | ||
| DLG_SAVE_SHOW_FILEOPTIONS_QFACTOR | ||
| DLG_SAVE_SHOW_FILEOPTIONS_J2KOPTIONS | ||
| DLG_SAVE_SHOW_FILEOPTIONS_BASICJ2KOPTIONS | ||
| DLG_SAVE_ENABLESIZING | ||
| DLG_SAVE_SHOW_FILEOPTIONS_JBIG2OPTIONS | ||
| DLG_SAVE_SHOW_FILEOPTIONS_PDFPROFILES ( FOR V16 only) | ||
| pfnHelpCallback | Pointer to an optional help callback function. If you do not wish to provide help to this dialog, use NULL as the value of this parameter. To provide help to this dialog, use the function pointer as the value of this parameter. The callback function must adhere to the prototype described in LTCOMMDLGHELPCB. | |
| pHelpCallBackUserData | Void pointer that you can use to pass one or more additional parameters that the callback function needs. To use this feature, assign a value to a variable or create a structure that contains as many fields as you need. Then, in this parameter, pass the address of the variable or structure, casting it to L_VOID *. The callback function, which receives the address in its own pHelpCallBackUserData parameter, can cast it to a pointer of the appropriate data type to access your variable or structure. If the additional parameters are not needed, you can pass NULL in this parameter. | |
| FileJBIG2Options | A structure that contains the options to use when saving JBIG2 files. | |
| InitialView | Specifies how OpenFileDialog displays the items in the ListView control. For a list of possible values, refer to INITIALVIEWENUM. | |
| PDFProfiles | Specifies the Specifies the PDF profile to be used when saving. For a list of possible values, refer to PDFPROFILESENUM (For V16 only). | |
