Hello all,

Thank you for your help and the [tabset] object _is_ in zexy!

Cheers,

Stephanie and Alexandre

Hello all,

We are working on getting values from an image to a pd
array. We are using maxlib's [tabset] to write the

values

to an array but the values are ints ranging from 0-255

and

we'd like to get floats from -1 to 1. Since gridflow

deals

only with ints currently, are operations on lists

possible

in pd?

not in the core pd.

but there are libraries like Gem, providing [v+] [v*]

(for

adding/multiplication vectors and scalars), zexy [.] (in

product of

either 2 vectors or 1 vector and 1 scalar; note: zexy

also provides a

[tabset] so you might get a name-clash)

furthermore there should be johannes taelman's SMlib,

which provides a

lot of objects for dealing with vectors (and very

complex operations too)

if you don't want to use any other lib, you could copy

the content of

one table to another table (with [tabread] & [tabwrite]

and doing the

math on scalars)
