I would like to convert emails (*.eml files) to html including css, pictures (despite whether attached or referenced), formatting. Can your library handle this? I could find example of converting html to email, but not the other way around, so Im writing to you.
The Chilkat Email object has an UnpackHtml method that does what you are describing. See the online reference documentation for (depending on your language) Chilkat.Email, CkEmail, CkoEmail, ChilkatEmail2, etc.
For example, the C# email object documentation is located here: http://www.chilkatsoft.com/refdoc/csEmailRef.html
