Как
перевести RTF в HTML?
Здесь процедура, которую я использую для конвертации содержимого
RichEdit в код SGML. Она не создает полноценный HTML-файл, но Вы можете
расширить функциональность, указал, какие RTF-коды Вы желаете конвертировать
в какие-либо HTML-тэги.
function rtf2sgml (text : string) : string; {Funktion for att konvertera en RTF-rad till SGML-text.} var temptext : string; start : integer; begin text := stringreplaceall (text,'&','##amp;'); text := stringreplaceall (text,'##amp','&'); text := stringreplaceall (text,'\'+chr(39)+'e5','a'); text := stringreplaceall (text,'\'+chr(39)+'c5','A'); text := stringreplaceall (text,'\'+chr(39)+'e4','a'); text := stringreplaceall (text,'\'+chr(39)+'c4','A'); text := stringreplaceall (text,'\'+chr(39)+'f6','o'); text := stringreplaceall (text,'\'+chr(39)+'d6','O'); text := stringreplaceall (text,'\'+chr(39)+'e9','e'); text := stringreplaceall (text,'\'+chr(39)+'c9','E'); text := stringreplaceall (text,'\'+chr(39)+'e1','a'); text := stringreplaceall (text,'\'+chr(39)+'c1','A'); text := stringreplaceall (text,'\'+chr(39)+'e0','a'); text := stringreplaceall (text,'\'+chr(39)+'c0','A'); text := stringreplaceall (text,'\'+chr(39)+'f2','o'); text := stringreplaceall (text,'\'+chr(39)+'d2','O'); text := stringreplaceall (text,'\'+chr(39)+'fc','u'); text := stringreplaceall (text,'\'+chr(39)+'dc','U'); text := stringreplaceall (text,'\'+chr(39)+'a3','?'); text := stringreplaceall (text,'\}','#]#'); text := stringreplaceall (text,'\{','#[#'); text := stringreplaceall (text,'{\rtf1\ansi\deff0\deftab720','');{Skall alltid tas bort} text := stringreplaceall (text,'{\fonttbl',''); {Skall alltid tas bort} text := stringreplaceall (text,'{\f0\fnil MS Sans Serif;}','');{Skall alltid tas bort} text := stringreplaceall (text,'{\f1\fnil\fcharset2 Symbol;}','');{Skall alltid tas bort} text := stringreplaceall (text,'{\f2\fswiss\fprq2 System;}}','');{Skall alltid tas bort} text := stringreplaceall (text,'{\colortbl\red0\green0\blue0;}','');{Skall alltid tas bort} {I version 2.01 av Delphi finns inte \cf0 med i RTF-rutan.
