[PD-dev] Canvas and ojb/cnv arguments in .pd

[Dave S]

Hello all,

In regards to my earlier question: "What is the last argument of [cnv] for?"


1. Here's a blurb from the "Unofficial Documentation of PD File Format" at
http://student-kmt.hku.nl/%7Etjeerd/pd/pd_fileformat.html#r369 which is an
excellent paper by Simon Asselbergs and Tjeerd Sietsma:

Syntax: #X obj [x_pos] [y_pos] cnv [size] [width] [height] [send] [receive]
[label] [x_off] [y_off] [font] [font_size] [bg_color] [label_color] [?];
[?] - unknown value, default is zero 
Remarks: We couldn't find the purpose of the final value.


2.  And Miller's description of PD's File Format doesn't appear to give us
any clues (or I haven't yet found a clue).


So, the question stands:
What is the last argument of [cnv] for?

AS IN:
#X obj 0 0 cnv 15 768 22 cnv_heading_S cnv_heading_R All_About_Canvases 12
12 0 14 -233017 -1 0;


Does anybody know?

Regards,
Dave S
