Geglcreate_chain_argv

Declaration [src] 

void
gegl_create_chain_argv (
  char** ops,
  GeglNode* op_start,
  GeglNode* op_end,
  double time,
  int rel_dim,
  const char* path_root,
  GError** error
)

Description [src]

Create a node chain from argv style list of op data.

Parameters

ops

Type: char**

An argv style, NULL terminated array of arguments.

The data is owned by the caller of the function.
The value is a NUL terminated UTF-8 string.
op_start

Type: GeglNode

Node to pass in as input of chain.

The data is owned by the caller of the function.
op_end

Type: GeglNode

Node to get processed data.

The data is owned by the caller of the function.
time

Type: double

The time to use for interpolatino of keyframed values.

rel_dim

Type: int

Relative dimension to scale rel suffixed values by.

path_root

Type: const char*

The value is a NUL terminated UTF-8 string.
error

Type: GError **

The return location for a recoverable error.

The argument can be NULL.
If the return location is not NULL, then you must initialize it to a NULL GError*.
The argument will left initialized to NULL by the function if there are no errors.
In case of error, the argument will be set to a newly allocated GError; the caller will take ownership of the data, and be responsible for freeing it.
