public class MinimalHTMLWriter extends AbstractWriter
MinimalHTMLWriter is a fallback writer used by the HTMLEditorKit to write out HTML for a document that is a not produced by the EditorKit. The format for the document is:
<html> <head> <style> <!-- list of named styles p.normal { font-family: SansSerif; margin-height: 0; font-size: 14 } --> </style> </head> <body> <p style=normal> Bold, italic, and underline attributes of the run are emitted as HTML tags. The remaining attributes are emitted as part of the style attribute of a <span> tag. The syntax is similar to inline styles. </p> </body> </html>
