settings

Examples

Conversion example 1

The RTF for this example has been created from the original RTF specification using LibreOffice.

Input (RTF document) - as shown in MS Wordpad
example 1 RTF
Notes
  • Wordpad auto-detects URLs and renders them as hyperlinks, even if they do not use a HYPERLINK field. With ScroogeXHTML, this auto-detection can be emulated in a post-processing step.
  • Wordpad renders table borders with a light grey line, even if it has no border style. This may be achieved with CSS in ScroogeXHTML.
Output (HTML document) - as shown in Mozilla Firefox
example 1 HTML
Notes
  • To create similar grey borders around table cells as in Wordpad, the custom CSS for the conversion includes a custom border format: 
td {
  vertical-align: top;
  border: 1px solid silver;
}

Conversion example 2

The RTF for this example has been created using LibreOffice 6.1.6.3, then opened in MS Wordpad.

Input (RTF document) - as shown in MS Wordpad
example 2 RTF
Notes
  • The first picture uses the JPG format, the second uses PNG
Output (HTML document) - as shown in Mozilla Firefox
example 2 HTML
Notes
