Is there any library for ePub

I want to write a converter that gives me full control over converting PDF to ePUB? I watch the converter

• - Do not cut out the words at the end of the line. If the text is a single paragraph, then epub should be a single paragraph without any additional space for characters and cut-off words.
• - recognize bookmarks in a pdf document and create a table of contents (TOC) in the epub version.
• must resize images.
• must be in UTF8, its a must be compatible for Turkish characters.

Please offer me any library for this?
