| 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. | |
| 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. More... | |
| 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. | |
| virtual DataBuf | write () const |
| Return the image header in binary format. The caller owns this data and DataBuf ensures that it will be deleted. More... | |
| virtual void | print (std::ostream &os, const std::string &prefix="") const |
| Print debug info for the image header to os. More... | |
| 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. | |

Return true if the Exif tag from group is an image tag.
Certain tags of TIFF and TIFF-like images are required to correctly display the primary image. These image tags contain image data rather than metadata.
| tag | Tag number. |
| group | Group identifier. |
| pPrimaryGroups | Pointer to a list of TIFF groups that contain primary images, empty if none are marked. |
false. Reimplemented from Exiv2::Internal::TiffHeaderBase.
