Martin (1992: 521-3):
Some examples of linguistically and pictorially projected texts across three modes are outlined in Table 7.8.
Table 7.8. Projection across modes field-structured:accompanying (re-)constructing genre-structured linguistic simultaneous narrative quotations translation dialogue pictorial comic strip comic strip figures, tables dialogue headers
 In terms of first-order experience, the dialogue and headers of comic strips are verbal projections of the author; that is, they are linguistic, not pictorial. In terms, of second-order experience, the dialogues of comic strips are projections of the characters; again, they are linguistic, not pictorial. It is the drawing that accompanies these wordings that is pictorial.
Language and pictures are distinct semiotic modes; that is, distinct semiotic systems. Pictorial semiosis differs from language, both in terms of its expression plane and in not having a stratified content plane (meaning without wording).
 The projection relation between speaker/writer and text is ideational, not textual, and so is not a feature of mode.
 Again, the use of the word 'texts' here betrays the ongoing confusion between text types (registers) and context (mode). The confusion is thus along two theoretical dimensions simultaneously: stratification (context vs language) and instantiation (system vs instance type).
 In terms of Hasan's (1985/9: 58) mode opposition of constitutive vs ancillary, the rôle of the language of comic strips is constitutive, not ancillary to something else.
