If you are writing a language binding, you won't need these. Instead, make
|
|
a new operation with vips_operation_new() (all it does is look up the
|
|
operation by name with vips_type_find(), then call g_object_new() for you),
|
|
then use vips_argument_map() and friends to loop over the operation's
|
|
arguments setting them. Once you have set all arguments, use
|
|
vips_cache_operation_build() to look up the operation in the cache and
|
|
either build or dup it. If something goes wrong, you'll need to use
|
|
vips_object_unref_outputs() and g_object_unref() to free the
|
|
partially-built object.
