getFlags
Arguments
| :: (HasCallStack, MonadIO m, IsOperation a) | |
| => a |
|
| -> m [OperationFlags] | Returns: 0 on success, or -1 on error. |
Returns the set of flags for this operation.
invalidate
operationInvalidate :: (HasCallStack, MonadIO m, IsOperation a) => a -> m () Source #
No description available in the introspection data.
new
Arguments
| :: (HasCallStack, MonadIO m) | |
| => Text |
|
| -> m Operation | Returns: the new operation. |
Return a new Operation with the specified nickname. Useful for
language bindings.
You'll need to set
any arguments and build the operation before you can use it. See
vips_call() for a higher-level way to make new operations.
Signals
invalidate
type C_OperationInvalidateCallback = Ptr () -> Ptr () -> IO () Source #
Type for the callback on the (unwrapped) C side.
type OperationInvalidateCallback = IO () Source #
No description available in the introspection data.
afterOperationInvalidate :: (IsOperation a, MonadIO m) => a -> OperationInvalidateCallback -> m SignalHandlerId Source #
Connect a signal handler for the invalidate signal, to be run after the default handler. When overloading is enabled, this is equivalent to
after operation #invalidate callback
genClosure_OperationInvalidate :: MonadIO m => OperationInvalidateCallback -> m (GClosure C_OperationInvalidateCallback) Source #
Wrap the callback into a GClosure.
mk_OperationInvalidateCallback :: C_OperationInvalidateCallback -> IO (FunPtr C_OperationInvalidateCallback) Source #
Generate a function pointer callable from C code, from a C_OperationInvalidateCallback.
noOperationInvalidateCallback :: Maybe OperationInvalidateCallback Source #
A convenience synonym for Nothing :: Maybe OperationInvalidateCallback
onOperationInvalidate :: (IsOperation a, MonadIO m) => a -> OperationInvalidateCallback -> m SignalHandlerId Source #
Connect a signal handler for the invalidate signal, to be run before the default handler. When overloading is enabled, this is equivalent to
on operation #invalidate callback
