Member Enumeration Documentation

enum Celartem::TIFF6::FieldType

This enumeration defines the field types defined in TIFF 6.0 specification.
All types enumerated here is defined in TIFF 6.0 except IFD type. IFD type is defined in the following document:
"Adobe PageMaker(R) 6.0 TIFF Technical Notes"
1995, Adobe Systems Incorporated.
http://partners.adobe.com/asn/developer/pdfs/tn/TIFFPM6.pdf

Enumerator:
BYTE  8-bit unsigned integer.
ASCII  8-bit byte that contains a 7-bit ASCII code; the last byte must be NUL (binary zero).
SHORT  16-bit (2-byte) unsigned integer.
LONG  32-bit (4-byte) unsigned integer.
RATIONAL  Two LONGs: the first represents the numerator of a fraction; the second, the denominator.
SBYTE  An 8-bit signed (twos-complement) integer.
UNDEFINED  An 8-bit byte that may contain anything, depending on the definition of the field.
SSHORT  A 16-bit (2-byte) signed (twos-complement) integer.
SLONG  A 32-bit (4-byte) signed (twos-complement) integer.
SRATIONAL  Two SLONGfs: the first represents the numerator of a fraction, the second the denominator.
FLOAT  Single precision (4-byte) IEEE format.
DOUBLE  Double precision (8-byte) IEEE format.
IFD  IFD is otherwise identical to LONG, but is only used to point to other valid IFDs.

static const u32* Celartem::TIFF6::getAsLONG ( const DataStore *  inDataStore,
const String &  inTag,
size_t *  outCount = NULL 
) [static]

This function returns the specified TIFF tag data as a u32 array from the DataStore instance if the array type is TIFF6::LONG. You can assume that the function does not throw any exceptions.

Parameters:
inDataStore The DataStore instance.
inTag The tag to search.
outCount Pointer to a size_t variable that receives the count of the data. It can be NULL if you don't need the count.
Returns:
The data of the tag. If any errors (the value is not found, the type mismatchs, ...), this function returns NULL.
