Inheritance diagram for Exiv2::Internal::TiffEntryBase:
Public Member Functions | |
Creators | |
TiffEntryBase (uint16_t tag, uint16_t group, TiffType tiffType=ttUndefined) | |
Default constructor. | |
virtual | ~TiffEntryBase () |
Virtual destructor. | |
Manipulators | |
void | encode (TiffEncoder &encoder, const Exifdatum *datum) |
Encode a TIFF component from the metadatum provided and information from the encoder as needed. | |
void | setOffset (int32_t offset) |
Set the offset. | |
void | setData (byte *pData, int32_t size) |
Set pointer and size of the entry's data (not taking ownership of the data). | |
void | setData (DataBuf buf) |
Set the entry's data buffer, taking ownership of the data buffer passed in. | |
void | updateValue (Value::AutoPtr value, ByteOrder byteOrder) |
Update the value. Takes ownership of the pointer passed in. | |
void | setValue (Value::AutoPtr value) |
Set tag value. Takes ownership of the pointer passed in. | |
Accessors | |
TiffType | tiffType () const |
Return the TIFF type. | |
int32_t | offset () const |
Return the offset to the data area relative to the base for the component (usually the start of the TIFF header). | |
virtual int | idx () const |
Return the unique id of the entry in the image. | |
const byte * | pData () const |
Return a pointer to the binary representation of the value of this component. | |
const Value * | pValue () const |
Return a const pointer to the converted value of this component. | |
Protected Member Functions | |
Protected Manipulators | |
virtual void | doEncode (TiffEncoder &encoder, const Exifdatum *datum)=0 |
Implements encode(). | |
void | setCount (uint32_t count) |
Set the number of components in this entry. | |
void | setIdx (int idx) |
Set the unique id of the entry in the image. | |
virtual uint32_t | doWrite (IoWrapper &ioWrapper, ByteOrder byteOrder, int32_t offset, uint32_t valueIdx, uint32_t dataIdx, uint32_t &imageIdx) |
Implements write(). Write the value of a standard TIFF entry to the ioWrapper, return the number of bytes written. Only the ioWrapper and byteOrder arguments are used. | |
Protected Accessors | |
virtual uint32_t | doCount () const |
Implements count(). | |
virtual uint32_t | doWriteData (IoWrapper &ioWrapper, ByteOrder byteOrder, int32_t offset, uint32_t dataIdx, uint32_t &imageIdx) const |
Implements writeData(). Standard TIFF entries have no data: write nothing and return 0. | |
virtual uint32_t | doWriteImage (IoWrapper &ioWrapper, ByteOrder byteOrder) const |
Implements writeImage(). Standard TIFF entries have no image data: write nothing and return 0. | |
virtual uint32_t | doSize () const |
Implements size(). Return the size of a standard TIFF entry. | |
virtual uint32_t | doSizeData () const |
Implements sizeData(). Return 0. | |
virtual uint32_t | doSizeImage () const |
Implements sizeImage(). Return 0. | |
Static Protected Member Functions | |
uint32_t | writeOffset (byte *buf, int32_t offset, TiffType tiffType, ByteOrder byteOrder) |
Helper function to write an offset to a preallocated binary buffer. | |
Friends | |
class | TiffReader |
class | TiffEncoder |
int | selectNikonLd (TiffBinaryArray *const, TiffComponent *const) |
|
Encode a TIFF component from the metadatum provided and information from the encoder as needed. Implemented as double-dispatch calls back to one of the specific encoding functions at the encoder. |
|
Set tag value. Takes ownership of the pointer passed in. Update type, count and the pointer to the value. |
|
Update the value. Takes ownership of the pointer passed in. Update binary value data and call setValue(). |
