JPEG (Joint Photographic Experts Group) Feature Type Format Attributes

In addition to the generic FME feature attributes that FME Workbench adds to all features (see About Feature Type Attributes), this format also adds format-specific attributes (Format Attributes).

Attribute	Description
jpeg_exif_aperturevalue	Represents the lens aperture. The unit is the APEX value. This is a reader attribute.
jpeg_exif_cfapattern	The color filter array (CFA) geometric pattern of the image sensor when a one-chip color area sensor is used. It does not apply to all sensing methods. This is a reader attribute.
jpeg_exif_colorspace	Represents the color space information tag is always recorded as the color space specifier. Normally sRGB (=1) is used to define the color space based on the PC monitor conditions and environment. If a color space other than sRGB is used, uncalibrated (=FFFF) is set. Image data recorded as uncalibrated can be treated as sRGB when it is converted to Flashpix. The value can be: 1 - sRGB FFFF - uncalibrated Other - reserved This is a reader attribute.
jpeg_exif_componentsconfiguration	Represents information specific to compressed data. The channels of each component are arranged in order from the 1st component to the 4th. For uncompressed data the data arrangement is given in the photometric interpretation tag. However, since photometric interpretation can only express the order of Y, Cb, and Cr, this tag is provided for cases when compressed data uses components other than Y, Cb, and Cr and to enable support of other sequences. The value can be: 0 - does not exist 1 - Y 2 - Cb 3 - Cr 4 - R 5 - G 6 - B Other - reserved The default is 4 5 6 0 (if RGB uncompressed) or 1 2 3 0 (other cases). This is a reader attribute.

When the date and time are unknown, all the character spaces except colons (“:”) may be filled with blank characters, or else the interoperability field may be filled with blank characters. The characters string length is 20 bytes including a null character for termination. When the field is left blank, it is treated as unknown. This is a reader attribute.
