Property item descriptions
The following list gives descriptions of the property items supported by Windows GDI+. The descriptions are brief and general so that they apply to a variety of image file formats. For a detailed description of how a property item is used by a particular file format, see the specification for that file format. For links to several file specifications and other documents that describe metadata in detail, see Image File Format Specifications.
The Exchangeable Image File (EXIF) format is a Japan Electronic Industry Development Association (JEIDA) standard, revised June 1998 as version 2.1. Portions of the EXIF specification are used with permission of JEIDA.
The types in the Type column are described in Image property tag type constants.

PropertyTagSRGBRenderingIntent
How the image should be displayed as defined by the International Color Consortium (ICC). If a GDI+ Image object is constructed with the useEmbeddedColorManagement parameter set to TRUE, then GDI+ renders the image according to the specified rendering intent. The intent can be set to perceptual, relative colorimetric, saturation, or absolute colorimetric.
- Perceptual intent, which is suitable for photographs, gives good adaptation to the display device gamut at the expense of colorimetric accuracy.
- Relative colorimetric intent is suitable for images (for example, logos) that require color appearance matching that is relative to the display device white point.
- Saturation intent, which is suitable for charts and graphs, preserves saturation at the expense of hue and lightness.
- Absolute colorimetric intent is suitable for proofs (previews of images destined for a different display device) that require preservation of absolute colorimetry.

PropertyTagExifFPXVer
FlashPix format version supported by an FPXR file. If the FPXR function supports FlashPix format version 1.0, this is indicated similarly to PropertyTagExifVer by recording 0100 as a 4-byte ASCII string. Because the type is PropertyTagTypeUndefined, there is no NULL terminator.

PropertyTagExifColorSpace
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 (=0xFFFF) is set. Image data recorded as Uncalibrated can be treated as sRGB when it is converted to FlashPix.

PropertyTagExifPixXDim
Information specific to compressed data. When a compressed file is recorded, the valid width of the meaningful image must be recorded in this tag, whether or not there is padding data or a restart marker. This tag should not exist in an uncompressed file.

|---|---|
| Tag | 0xA002 |
| Type | PropertyTagTypeShort or PropertyTagTypeLong |

PropertyTagExifPixYDim
Information specific to compressed data. When a compressed file is recorded, the valid height of the meaningful image must be recorded in this tag whether or not there is padding data or a restart marker. This tag should not exist in an uncompressed file. Because data padding is unnecessary in the vertical direction, the number of lines recorded in this valid image height tag will be the same as that recorded in the SOF.

PropertyTagExifRelatedWav
The name of an audio file related to the image data. The only relational information recorded is the EXIF audio file name and extension (an ASCII string that consists of 8 characters plus a period (.), plus 3 characters). The path is not recorded. When you use this tag, audio files must be recorded in conformance with the EXIF audio format. Writers can also store audio data within APP2 as FlashPix extension stream data.
