TiffHeaderBase (uint16_t tag, uint32_t size, ByteOrder byteOrder, uint32_t offset) | |
Constructor taking tag, size and default byteOrder and offset. | |
virtual | ~TiffHeaderBase ()=0 |
Virtual destructor. | |
Manipulators | |
virtual bool | read (const byte *pData, uint32_t size) |
Read the image header from a data buffer. Return false if the data buffer does not contain an image header of the expected format, else true. | |
virtual void | setByteOrder (ByteOrder byteOrder) |
Set the byte order. | |
virtual void | setOffset (uint32_t offset) |
Set the offset to the start of the root directory. | |
Accessors | |
virtual uint32_t | write (Blob &blob) const |
Write the image header to the binary image blob. This method appends to the blob. | |
virtual void | print (std::ostream &os, const std::string &prefix="") const |
Print debug info for the image header to os. | |
virtual ByteOrder | byteOrder () const |
Return the byte order (little or big endian). | |
virtual uint32_t | offset () const |
Return the offset to the start of the root directory. | |
virtual uint32_t | size () const |
Return the size (in bytes) of the image header. | |
virtual uint16_t | tag () const |
Return the tag value (magic number) which identifies the buffer as TIFF data. |
void Exiv2::Internal::TiffHeaderBase::print | ( | std::ostream & | os, | |
const std::string & | prefix = "" | |||
) | const [virtual] |
Print debug info for the image header to os.
os | Output stream to write to. | |
prefix | Prefix to be written before each line of output. |
bool Exiv2::Internal::TiffHeaderBase::read | ( | const byte * | pData, | |
uint32_t | size | |||
) | [virtual] |
Read the image header from a data buffer. Return false if the data buffer does not contain an image header of the expected format, else true.
pData | Pointer to the data buffer. | |
size | Number of bytes in the data buffer. |

uint32_t Exiv2::Internal::TiffHeaderBase::write | ( | Blob & | blob | ) | const [virtual] |
Write the image header to the binary image blob. This method appends to the blob.
blob | Binary image to add to. |
