- output arrays need an extra * in

input int works

input double

input enum works

input image works

output blob
|

|

call( "thing", options->set( "out-array", &out_array ) );
|
||||
- set of overloads
|
||||
|
||||
and call will new() a vector and place the pointer in out_array
|
||||
- something to make an image matched to another image from a vector or a
|
||||
single constant
|
||||
|
||||
alternative:
|
||||
|
||||
std::vector<double> out_array;
|
||||
|
||||
call( "thing", options->set( "out-array", &out_array ) );
|
||||
|
||||
now the caller must pass in an empty vector (or not?) which we fill (or
|
||||
empty?) ... seems odd, but makes lifetime management much simpler
|
||||
- something to make an image from an array of constants, need to set
|
||||
scale/offset too
|
||||
|
||||
- new_from_buffer(), new_from_memory(), write_to_memory() etc etc
