PDF, or portable document format, opens in the Adobe Reader. The PDF export filter has a number of useful properties that allow you to control your output. You can set the properties either in code using the PDFExport object after adding reference to the following assembly in your project, or by selecting the object in the toolbox and adding it to the component tray below the Form which automatically adds this assembly to the project:
GrapeCity.ActiveReports.Export.Pdf.v8.dll
With the PDF export filter, you can use such features as Font Linking, Custom Font Factory and end-user defined characters (EUDC).

Note: These features are only available in the Professional Edition of ActiveReports. |
PDF Export Properties
Property |
Valid Values |
Description |
ConvertMetaToPng |
True or False (default) |
Set to True to change any Windows metafile images to PNG format to keep the file size down. If the report has no metafiles, this setting is ignored. |
ExportBookmarks |
True (default) or False |
Set to True to generate bookmarks from the bookmarks in the report. If the report has no bookmarks, this setting is ignored. To control how the exported bookmarks are displayed, use Options.DisplayMode detailed below. |
FontFallback |
String of font families |
Set a comma-delimited string of font families to be used to lookup glyphs missing in the original font. |
ImageQuality |
Lowest, Medium (default), or Highest |
Set to Highest in combination with a high value in the ImageResolution property to yield the best printing results when converting Windows metafiles (.wmf and .emf). Set to Lowest to keep the file size down. If the report has no metafiles, this setting is ignored. |
ImageResolution |
75 - 2400 dpi |
Set to 75 dpi to save space, 150 dpi for normal screen viewing, and 300 dpi or higher for print quality. Use this property in combination with ImageQuality (highest) to yield the best results when the report contains metafiles or the Page.DrawPicture API is used. Neither property has any effect on other image types. |
