#X text 1 1 _______________________________;
#X text 47 25 The svg specification has some handy attributes which
can be used to animate the transition between values for other attributes.
Unfortunately the new [draw] commands don't currently support those
attributes.;
#X text 47 82 However \, if you can do the same thing using some of
Pd's core objects. For example \, with [line] you can create a ramp
between values.;
#X obj 47 158 tgl 23 0 empty empty empty 17 7 0 10 -4034 -1 -1 0 1
;
#X msg 47 210 \$1 500;
#X text 47 371 This is less efficient than svg's animation interface.
Here \, Pd must send a message for each change in value during the
ramp. However \, you can use the 2nd argument to [line] to tell it
how many milliseconds it should wait before outputting a ramp value.
Use the objects below to convert between "grain" rate and frames-per-second.

#X text 112 458 <-- If you want to convert grain-rate to fps \, type
the grain-rate in the box and read out the answer in the bottom box.
On the other hand if you want to convert fps to grain-rate simply think
your desire at the patch and Pd will automatically do the conversion
in the other direction!;
