public struct ImageTag

Remarks

A wrapper around an image meta data tag. (Tiff, Exif and others)

IIQ files contain meta data tags following multiple paradigms. Some tags are defined by the Tiff format standard, some by Exif and yet some are Phase One proprietary tags.

This class represents data contained in all such types of tags. See the class TagId, that identify all 3 kind of tags.

Each tag has a type and a count, and some raw data. The count is used only to represent vector data types or fractions. (A vector of 2: numerator & denominator.)

Properties

Data	Get the raw data value of this tag
StringValue	Get a string with the value of this meta data tag. (only for ASCII and BYTE types)
DoubleValue	Return the value for tag types: double, float and rationals - as a double
TagId	The tag ID, as defined by either Tiff, Exif or Phase One stardard
Type	The data-type of this meta data tag.
Count	If this tag represents a vector, this is the number of elements in the vector.
ByteSize	The size of the meta data tag in bytes
IntValue	Get the signed integer value of this tag
UIntValue	Get the unsigned integer value of this tag
RationalValue	Get the signed rational (fraction representation) value of this meta data tag
URationalValue	Get the unsigned rational (fraction representation) value of this meta data tag

Methods

ToString()
operator byte(ImageTag tag)	Explicit operator converting a ImageTag to a byte. Requires that the ImageTag is type byte. If not, an SdkException is thrown with the error-code kErrorPropertyTypeInvalid.
operator Int32(ImageTag p)
operator UInt32(ImageTag p)
operator double(ImageTag p)
operator string(ImageTag p)
