Macro Definition Documentation

◆ MPIX_OP_INPUT_BYTES

#define MPIX_OP_INPUT_BYTES ( ... ) { int e = mpix_op_input_bytes(__VA_ARGS__); if (e) return e; }

Call mpix_op_input_bytes() and return the error if any

◆ MPIX_OP_INPUT_DONE

Call mpix_op_input_done() and return the error if any

◆ MPIX_OP_INPUT_FLUSH

#define MPIX_OP_INPUT_FLUSH ( ... ) { int e = mpix_op_input_flush(__VA_ARGS__); if (e) return e; }

Call mpix_op_input_flush() and return the error if any

◆ MPIX_OP_INPUT_LINES

#define MPIX_OP_INPUT_LINES ( ... ) { int e = mpix_op_input_lines(__VA_ARGS__); if (e) return e; }

Call mpix_op_input_lines() and return the error if any

◆ MPIX_OP_INPUT_PEEK

#define MPIX_OP_INPUT_PEEK ( ... ) { int e = mpix_op_input_peek(__VA_ARGS__); if (e) return e; }

Call mpix_op_input_peek() and return the error if any

◆ MPIX_OP_OUTPUT_DONE

#define MPIX_OP_OUTPUT_DONE ( ... ) { int e = mpix_op_output_done(__VA_ARGS__); if (e) return e; }

Call mpix_op_output_done() and return the error if any

◆ MPIX_OP_OUTPUT_FLUSH

#define MPIX_OP_OUTPUT_FLUSH ( ... ) { int e = mpix_op_output_flush(__VA_ARGS__); if (e) return e; }

Call mpix_op_output_flush() and return the error if any

◆ MPIX_OP_OUTPUT_LINE

#define MPIX_OP_OUTPUT_LINE ( ... ) { int e = mpix_op_output_line(__VA_ARGS__); if (e) return e; }

Call mpix_op_output_line() and return the error if any

◆ MPIX_OP_OUTPUT_PEEK

#define MPIX_OP_OUTPUT_PEEK ( ... ) { int e = mpix_op_output_peek(__VA_ARGS__); if (e) return e; }

Call mpix_op_output_peek() and return the error if any

◆ MPIX_REGISTER_OP

#define MPIX_REGISTER_OP	(	name,
		...
	)	MPIX_REGISTER_NB(name, ## __VA_ARGS__, P_NB)

Register an operation globally in the library.

The declaration is collected by generated.py which adds it to the MPIX_FOR_EACH_OP() macro used to generate code.

Parameters

name	The identifier assigned to the operation
...	A list of parameter names in their correct order.

Function Documentation

◆ mpix_op_append()

static void * mpix_op_append	(	struct mpix_image *	img,
		enum mpix_op_type	op_type,
		size_t	op_sz,
		size_t	buf_sz
	)

inlinestatic

Allocate a new operation and add it to an image pipeline.
