Include dependency graph for openexr_context.h:

This graph shows which files directly or indirectly include this file:

Classes
struct	_exr_context_initializer_v3
	Struct used to pass function pointers into the context initialization routines. More...

Macros
#define	EXR_CONTEXT_FLAG_STRICT_HEADER (1 << 0)
	context flag which will enforce strict header validation checks and may prevent reading of files which could otherwise be processed. More...

#define	EXR_CONTEXT_FLAG_SILENT_HEADER_PARSE (1 << 1)
	Disables error messages while parsing headers. More...

#define	EXR_CONTEXT_FLAG_DISABLE_CHUNK_RECONSTRUCTION (1 << 2)
	Disables reconstruction logic upon corrupt / missing data chunks. More...

#define	EXR_CONTEXT_FLAG_WRITE_LEGACY_HEADER (1 << 3)
	Writes an old-style, sorted header with minimal information. More...

#define	EXR_DEFAULT_CONTEXT_INITIALIZER { sizeof (exr_context_initializer_t), 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, -2, -1.f, 0, { 0, 0, 0, 0 } }
	Simple macro to initialize the context initializer with default values. More...

typedef struct _exr_context_initializer_v3	exr_context_initializer_t
	Struct used to pass function pointers into the context initialization routines. More...

typedef enum exr_default_write_mode	exr_default_write_mode_t

Enumerations
enum	exr_default_write_mode { EXR_WRITE_FILE_DIRECTLY, EXR_INTERMEDIATE_TEMP_FILE }
	Enum describing how default files are handled during write. More...

Functions
EXR_EXPORT exr_result_t	exr_test_file_header (const char filename, const exr_context_initializer_t ctxtdata)
	Check the magic number of the file and report `EXR_ERR_SUCCESS` if the file appears to be a valid file (or at least has the correct magic number and can be read). More...

EXR_EXPORT exr_result_t	exr_finish (exr_context_t *ctxt)
	Close and free any internally allocated memory, calling any provided destroy function for custom streams. More...

EXR_EXPORT exr_result_t	exr_start_read (exr_context_t ctxt, const char filename, const exr_context_initializer_t *ctxtdata)
	Create and initialize a read-only exr read context. More...

EXR_EXPORT exr_result_t	exr_start_write (exr_context_t ctxt, const char filename, exr_default_write_mode_t default_mode, const exr_context_initializer_t *ctxtdata)
	Create and initialize a write-only context. More...

EXR_EXPORT exr_result_t	exr_start_inplace_header_update (exr_context_t ctxt, const char filename, const exr_context_initializer_t *ctxtdata)
	Create a new context for updating an exr file in place. More...

EXR_EXPORT exr_result_t	exr_get_file_name (exr_const_context_t ctxt, const char **name)

EXR_EXPORT exr_result_t	exr_get_user_data (exr_const_context_t ctxt, void **userdata)
	Query the user data the context was constructed with. This is perhaps useful in the error handler callback to jump back into an object the user controls. More...
