- Managing the PDF/A format
iParameterPDF (Function) In french: iParamètrePDF Defines the options for the generated PDF file. You can define: - the password used to open the file.
- the options for compressing images.
- the options for the presence of bookmarks.
- the options for protecting the PDF file. You also have the ability to define the password used to modify these protection options.
- the file format (Unicode, PDF/A).
From version 27, you can define all the PDF file generation options using pdfParameter variables. These settings are applied when printing a PDF file (file generated from the report viewer, or directly with iDestination).
Params is pdfParameter
Params.Quality = iHighQuality
Params.Zoom = zoomFullWidth
Params.PageDisplayMode = dispTwoPage + dispEnableScrolling + dispWithCoverPage
iParameterPDF(Params)
iDestination(iGenericPDF)
iPrintReport(MyReport)
ShellExecute(iLastFile())
iParameterPDF(iProtectionPrinting + iProtectionSelection, "", "Protection")
iDestination(iPDF, "C:\Temp\MyPDF.PDF")
iCreateFont(1, 16, iBold, iRoman)
PrintTitle()
PrintText()
iEndPrinting()
// No protection on the generated document
// Maximum image quality
iParameterPDF("", "", iMaximumQuality)
Â
// Create the PDF file
iDestination(iPDF, "C:\Temp\MyPDF.PDF")
// Print code
iCreateFont(1, 16, iBold, iRoman)
PrintTitle()
PrintText()
PrintImage()
// End of print and close the created PDF file
iEndPrinting()
Syntax
Configuring the PDF file via a pdfParameter variable Hide the details
iParameterPDF(<Parameters>)
<Parameters>: pdfParameter variable Name of the pdfParameter variable that describes all the options of the PDF file to be generated. This variable can be used to specify the format of the generated PDF file.
Protecting the PDF file by a password Hide the details
iParameterPDF(<Password> [, <Protection password>] [, <Quality and bookmark>])
<Password>: Character string - Password used to open the PDF file,
- Empty string if no password must be used.
<Protection password>: Optional character string Password used to change the protection options of the PDF file.Note: The PDF standard only supports passwords containing characters from the unaccented Latin character set. This means that accents, Chinese and Russian characters are not supported. <Quality and bookmark>: Optional Integer constant (or combination of constants) Configures:- Compression level of colors and grayscale.
- Management of bookmarks.
- Management of Unicode format.
| | | iAutomaticQuality | Compression level automatically calculated to generate a better-quality PDF file (especially for images). | | iAverageQuality | Average compression level. | | iBookmarkNone | No bookmark is taken into account by the PDF file. | | iBookmarkPage | The bookmarks are taken into account by the PDF file. A bookmark is automatically defined for each page in the PDF file. Each bookmark has a name in the following format "Page <page number>" (e.g. "Page 1"). | | iHighQuality | Low compression level used to get a high quality for the generated PDF. | | iLowQuality | High compression level. | | iMaximumQuality | Minimum compression level to get a maximum quality. This constant is recommended when creating a PDF file intended to be printed. | | iMinimumQuality | Maximum compression level. The quality will be minimum. This constant can be used to create a PDF file intended to be viewed on the screen. | | iPDFGrayscale | PDF file generated in black and white. | | iPDFUnicode | PDF in Unicode format.
Remarks:- The use of this constant is recommended if the characters found in the PDF file are wrongly encoded.
- If this constant is used, the size of the generated PDF file will increase significantly.

Selecting the protection options Hide the details
iParameterPDF(<Protection options> [, <Password> , <Protection password>] [, <Quality and bookmark>])
<Protection options>: Integer constant (or combination of constants) Format and requested protection: | | | iPDFA3b | PDF in PDF/A-3b format: - All the elements required to display or print the PDF file are included in the generated file. Therefore, the generated file is bigger.
- You can add files in various formats (XML, CSV, spreadsheets, word processing, etc.) to the PDF file. This can be done via iAddAttachment.
Note: This option is only taken into account for the current print job. Note: This format has certain limitations: - Transparency of images not supported.
- OpenType fonts not supported.
- Use of embedded fonts.
| iPDFA
or
iPDFA1b | PDF in PDF/A-1b format. All the elements required to display or print the PDF file are included in the generated file. Therefore, the generated file is bigger. Note: This option is only taken into account for the current print job. Note: This format has certain limitations: - Transparency of images not supported.
- OpenType fonts not supported.
- Use of embedded fonts.
| | iPDFGrayscale | PDF file generated in black and white. | | iPDFUnicode | PDF in Unicode format | | iProtectionComment | Restricts adding or editing comments. | | iProtectionModification | The content of the PDF file cannot be modified. | | iProtectionNone | No protection for the PDF file. | | iProtectionPrinting | The PDF file cannot be printed. | | iProtectionSelection | The content of the PDF file cannot be copied or extracted from the file. |
<Password>: Optional character string - Password used to open the PDF file,
- Empty string if no password must be used.
<Protection password>: Optional character string Password used to change the protection options of the PDF file. If this password corresponds to an empty string (""), a password is automatically generated. <Quality and bookmark>: Optional Integer constant (or combination of constants) Configures:- Color and grayscale compression quality.
- Management of bookmarks.
- Management of Unicode format.
| | | iAverageQuality | Average compression quality | | iBookmarkNone | No bookmark is taken into account by the PDF file | | iBookmarkPage | The bookmarks are taken into account by the PDF file. A bookmark is automatically defined for each page in the PDF file. Each bookmark has a name in the following format "Page <page number>" (e.g. "Page 1"). | | iHighQuality | High compression quality | | iLowQuality | Low compression quality | | iMaximumQuality | Maximum compression quality | | iMinimumQuality | Minimum compression quality | | iPDFUnicode | PDF in Unicode format. Note: Starting with version 21, this constant can be used in the <Protection options> parameter. |
Remarks - iParameterPDF is ignored in the middle of a print.
- The configuration defined with iParameterPDF is enabled:
- until the application or site is closed,
- until the next call to iParameterPDF,
- until the next call to iReset.
- If PDF/A-1b is enabled via iParameterPDF before displaying the print preview:
- The PDF export option changes from "PDF" to "PDF/A".
- For all print jobs sent from the preview (direct printing, etc.), there will be the same limitations as for the export to PDF/A format: Image transparency, font substitution, etc.
- By default, the generated PDF uses version 1.4. To generate the PDF file with a specific version, use a variable of type pdfParameter. You can use the Version property to set the version used for the generation.
Managing the PDF/A format Limitations:
- The transparency of images is not supported:
- If the image contains a transparent background in its format, the image will be drawn on a white background.
- If the "Transparent magenta" color is used, the image rendering may differ in the generated PDF.
- The "Opentype" fonts are not supported because the "Opentype" fonts cannot be incorporated in the generated PDF.
- All fonts use must be incorporated in the generated PDF and they must contain all displayed characters.
- In Windows, if characters are missing, the substitution font used is "Arial Unicode ms".
- In Linux, if characters are missing, an error is displayed.
Tip: How do I know if the printout in PDF/1-1b format will be correct? - If the print is performed from a report, you have the ability to enable the GUI errors specific to this format ("Options" tab in the description window of the report, "Enable the errors specific to the PDF/A-1b export" option).
- During a dynamic audit, the errors specific to the PDF/A-1b management are detected and displayed.
