Creators | |
TiffIfdMakernote (uint16_t tag, uint16_t group, uint16_t mnGroup, MnHeader *pHeader, bool hasNext=true) | |
Default constructor. | |
virtual | ~TiffIfdMakernote () |
Virtual destructor. | |
Manipulators | |
bool | readHeader (const byte *pData, uint32_t size, ByteOrder byteOrder) |
Read the header from a data buffer, return true if successful. | |
void | setByteOrder (ByteOrder byteOrder) |
Set the byte order for the makernote. | |
void | setImageByteOrder (ByteOrder byteOrder) |
Set the byte order used for the image. | |
Accessors | |
uint32_t | sizeHeader () const |
Return the size of the header in bytes. | |
uint32_t | writeHeader (IoWrapper &ioWrapper, ByteOrder byteOrder) const |
Write the header to a data buffer, return the number of bytes written. | |
uint32_t | mnOffset () const |
Return the offset to the makernote from the start of the TIFF header. | |
uint32_t | ifdOffset () const |
Return the offset to the start of the Makernote IFD from the start of the Makernote. Returns 0 if there is no header. | |
ByteOrder | byteOrder () const |
Return the byte order for the makernote. Requires the image byte order to be set (setImageByteOrder()). Returns the byte order for the image if there is no header or the byte order for the header is invalidByteOrder . | |
ByteOrder | imageByteOrder () const |
Return the byte order used for the image. | |
uint32_t | baseOffset () const |
Return the base offset for use with the makernote IFD entries relative to the start of the TIFF header. Returns 0 if there is no header. | |
Protected Member Functions | |
Protected Manipulators | |
virtual TiffComponent * | doAddPath (uint16_t tag, TiffPath &tiffPath, TiffComponent *const pRoot) |
Implements addPath(). The default implementation does nothing. | |
virtual TiffComponent * | doAddChild (TiffComponent::AutoPtr tiffComponent) |
virtual TiffComponent * | doAddNext (TiffComponent::AutoPtr tiffComponent) |
virtual void | doAccept (TiffVisitor &visitor) |
Implements accept(). | |
virtual uint32_t | doWrite (IoWrapper &ioWrapper, ByteOrder byteOrder, int32_t offset, uint32_t valueIdx, uint32_t dataIdx, uint32_t &imageIdx) |
Implements write(). Write the Makernote header, TIFF directory, values and additional data to the ioWrapper, return the number of bytes written. | |
Protected Accessors | |
virtual uint32_t | doWriteData (IoWrapper &ioWrapper, ByteOrder byteOrder, int32_t offset, uint32_t dataIdx, uint32_t &imageIdx) const |
This class does not really implement writeData(), it only has write(). This method must not be called; it commits suicide. | |
virtual uint32_t | doWriteImage (IoWrapper &ioWrapper, ByteOrder byteOrder) const |
Implements writeImage(). Write the image data of the IFD of the Makernote. Return the number of bytes written. | |
virtual uint32_t | doSize () const |
Implements size(). Return the size of the Makernote header, TIFF directory, values and additional data. | |
virtual uint32_t | doCount () const |
Implements count(). Return the number of entries in the IFD of the Makernote. Does not count entries which are marked as deleted. | |
virtual uint32_t | doSizeData () const |
This class does not really implement sizeData(), it only has size(). This method must not be called; it commits suicide. | |
virtual uint32_t | doSizeImage () const |
Implements sizeImage(). Return the total image data size of the makernote IFD. | |
Friends | |
class | TiffReader |
Contains a makernote header (which can be 0) and an IFD and implements child mgmt functions to deal with the IFD entries. The various makernote weirdnesses are taken care of in the makernote header (and possibly in special purpose IFD entries).
|
Read the header from a data buffer, return true if successful. The default implementation simply returns true. |
