Along with a lot of other juicy information about the Macintosh LaserWriter driver, there is a section called, "QuickDraw Comments for Text Rotation/Justification and Polygons." This section containts a complete description of how to rotate text using the LaserWriter. Here is some of what is described there: Using the PicComment routine to add comments to a picture, an application can take advantage of features that a printer might have which are not directly available in QuickDraw, such as rotated text. CommentType # data size data description TextBegin 150 6 bytes TTxtPicRec Begin special text TextEnd 151 none none End special text TextCenter 154 8 bytes TTxtCenter Offset for rotation where TTxtPicRec and TTxtCenter are Pascal records as follows: TTxtPicRec = PACKED RECORD tJus: Byte; {0,1,2,3,4:none,left,center,right,fill) tFlip: Byte; {0,1,2:none,horizontal,vertical} tRot: Integer; {0..360:degrees of rotation} tRes: Integer; {"reserved"} END; TTxtCenter = PACKED RECORD yInt: Integer; {Integer part of y offset to center} yFract: Integer; {Fractional part of y offset to center} xInt: Integer; {Integer part of x offset to center} xFract: Integer; {Fractional part of x offset to center} END; Then you can call like this to justify and/or flip text: PicComment(150,6,@TxtPicRec); {set justifying} DrawString('This text will be justified and flipped.'); PicComment(151,0,NIL); {end the special effects} To rotate text, try something like this: PicComment(150,6,@TxtPicRec); {set rotating} PicCommment(154,8,@TxtCenter); {specify center of rotation} DrawString('This text will be rotated.'); PicComment(151,0,NIL); {end the special effects} If you want to do any more than these few minimum things, try reading the Apple document, it is very useful for anyone using the LaserWriter.
