+This is the interface unit for the gd library, version 1.8.4.
+The gd library is a library to produce graphics files (jpeg,png and wbmp)
+
+The gd unit is a straight translation of the library headers.
+It has some additional calls which make it more pascal like:
+
+{overloaded pascal functions}
+function fopen(a,b:string):pFile;
+procedure gdImageChar(im:gdImagePtr; f:gdFontPtr; x:longint; y:longint; c:char; color:longint);
+procedure gdImageCharUp(im:gdImagePtr; f:gdFontPtr; x:longint; y:longint; c:char; color:longint); 
+procedure gdImageString(im:gdImagePtr; f:gdFontPtr; x:longint; y:longint; s:string;  color:longint); 
+procedure gdImageStringUp(im:gdImagePtr; f:gdFontPtr; x:longint; y:longint; s:string; color:longint); 
+procedure gdImageString16(im:gdImagePtr; f:gdFontPtr; x:longint; y:longint; s:string; color:longint); 
+procedure gdImageStringUp16(im:gdImagePtr; f:gdFontPtr; x:longint; y:longint; s:string; color:longint); 
+{$ifdef hasttf}
+function  gdImageStringTTF(im:PgdImage; brect:Plongint; fg:longint; fontlist:string; ptsize:double; angle:double; x:longint; y:longint; astring:string): string;
+function  gdImageStringFT(im:PgdImage; brect:Plongint; fg:longint; fontlist:string; ptsize:double; angle:double; x:longint; y:longint; astring:string):string;
+{$endif}
+
+These functions will work with both ansistrings and shortstrings; The unit
+can be compiled in both the {$H+} as the {$H-} state.
+
+The hasttf define should be defined for libraries which have TTF2 lib 
+support compiled in.
+
+The example is adapted from the example of the gd unit by Mike Bradbery.
+It shows how to use the pascal-like functions in the gd unit instead of the
+raw C like functions which use pchars.
+
+Michael.
