wPDF includes a device to create PDF files from ReportBuilder(tm) - (www.digital-metaphors.com)
It supports text, shape, barcode, line, bitmap, metafile, richtext (richedit) and also WPTools*) drawing commands. Metafiles are exported as vector graphics so there is no loss of resolution and the created PDF file will be as small as possible.
*) You need the latest version if the WPTools RB support units.
