nsIDocumentEncoder Interface

 
 Output only the selection (as opposed to the whole document).

const unsigned long OutputSelectionOnly = 1

 Plaintext output: Convert html to plaintext that looks like the html.
 Implies wrap (except inside <pre>), since html wraps.
 HTML, XHTML and XML output: do prettyprinting, ignoring existing formatting.
 XML output : it doesn't implicitly wrap

const unsigned long OutputFormatted = 2

 Don't do prettyprinting. Don't do any wrapping that's not in the existing
 HTML/XML source. This option overrides OutputFormatted if both are set.
 HTML/XHTML output: If neither are set, there won't be prettyprinting too, but
 long lines will be wrapped.
 Supported also in XML and Plaintext output.
 @note This option does not affect entity conversion.

const unsigned long OutputRaw = 4

 
 Do not print html head tags.
 XHTML/HTML output only.

const unsigned long OutputBodyOnly = 8

 Output as though the content is preformatted
 (e.g. maybe it's wrapped in a PRE or PRE_WRAP style tag)
 Plaintext output only.
 XXXbz How does this interact with
 OutputFormatted/OutputRaw/OutputPreformatted/OutputFormatFlowed?

const unsigned long OutputPreformatted = 16

 Wrap even if we're not doing formatted output (e.g. for text fields).
 Supported in XML, XHTML, HTML and Plaintext output.
 Set implicitly in HTML/XHTML output when no OutputRaw.
 Ignored when OutputRaw.
 XXXLJ: set implicitly in HTML/XHTML output, to keep compatible behaviors
        for old callers of this interface
 XXXbz How does this interact with OutputFormatFlowed?

const unsigned long OutputWrap = 32

 Output for format flowed (RFC 2646). This is used when converting
 to text for mail sending. This differs just slightly
 but in an important way from normal formatted, and that is that
 lines are space stuffed. This can't (correctly) be done later.
 PlainText output only.
 XXXbz How does this interact with
 OutputFormatted/OutputRaw/OutputPreformatted/OutputWrap?

const unsigned long OutputFormatFlowed = 64

 Convert links, image src, and script src to absolute URLs when possible.
 XHTML/HTML output only.

const unsigned long OutputAbsoluteLinks = 128

 Attempt to encode entities standardized at W3C (HTML, MathML, etc).
 This is a catch-all flag for documents with mixed contents. Beware of
 interoperability issues. See below for other flags which might likely
 do what you want.
 XHTML/HTML output only.

const unsigned long OutputEncodeW3CEntities = 256

 
 LineBreak processing: if this flag is set than CR line breaks will
 be written. If neither this nor OutputLFLineBreak is set, then we
 will use platform line breaks. The combination of the two flags will
 cause CRLF line breaks to be written.

const unsigned long OutputCRLineBreak = 512

 
 LineBreak processing: if this flag is set than LF line breaks will
 be written. If neither this nor OutputCRLineBreak is set, then we
 will use platform line breaks. The combination of the two flags will
 cause CRLF line breaks to be written.

const unsigned long OutputLFLineBreak = 1024

 Output the content of noscript elements (only for serializing
 to plaintext).

const unsigned long OutputNoScriptContent = 2048

 Output the content of noframes elements (only for serializing
 to plaintext).

const unsigned long OutputNoFramesContent = 4096

 Don't allow any formatting nodes (e.g. <br>, <b>) inside a <pre>.
 This is used primarily by mail. XHTML/HTML output only.

const unsigned long OutputNoFormattingInPre = 8192

 Encode entities when outputting to a string.
 E.g. If set, we'll output   if clear, we'll output 0xa0.
 The basic set is just   & < > " for interoperability
 with older products that don't support α and friends.
 XHTML/HTML output only.

const unsigned long OutputEncodeBasicEntities = 16384

 Encode entities when outputting to a string.
 The Latin1 entity set additionally includes 8bit accented letters
 between 128 and 255.
 XHTML/HTML output only.

const unsigned long OutputEncodeLatin1Entities = 32768

 Encode entities when outputting to a string.
 The HTML entity set additionally includes accented letters, greek
 letters, and other special markup symbols as defined in HTML4.
 XHTML/HTML output only.

const unsigned long OutputEncodeHTMLEntities = 65536

 Normally   is replaced with a space character when
 encoding data as plain text, set this flag if that's
 not desired.
 Plaintext output only.

const unsigned long OutputPersistNBSP = 131072
