MDM_EXIF_MAIN Properties

Gets or sets the name of the camera owner, photographer or image creator.

Gets or sets number of bits per image component. In this standard each component of the image is 8 bits, so the value for this tag is 8. Constant length of 3.

Gets or sets compression scheme used for the image data. When a primary image is JPEG compressed, this designation is not necessary and is omitted. When thumbnails use JPEG compression, this tag value is set to 6.

Gets or sets the photographer and editor copyrights. Constant length of 1-2.

Returns the number of metadata tags this instance represents.

Gets or sets the date and time of image creation.

Gets or sets the model name or model number of the equipment.

Returns whether this model exists in the bitmaps metadata structure.

Gets or sets a string giving the title of the image.

Gets or sets number of rows of image data. In JPEG compressed data a JPEG marker is used instead of this tag.

Gets or sets the number of columns of image data, equal to the number of pixels per row. In JPEG compressed data a JPEG marker is used instead of this tag.

Returns the metadata tag at the given index. This operation is slow when accessing all tags.

Gets or sets the offset to the start byte (SOI) of JPEG compressed thumbnail data. This is not used for primary image JPEG data.

Gets or sets the number of bytes of JPEG compressed thumbnail data.

Returns a list of all metadata tags this instance represents.

Gets or sets the manufacturer of the recording equipment.

Retrieves the datamodel that this instance represents.

Gets or sets the image orientation viewed in terms of rows and columns.

Gets or sets pixel composition. In JPEG compressed data a JPEG marker is used instead of this tag. See remarks for further information.

Gets or sets a value that indicates whether pixel components are recorded in chunky or planar format. In JPEG compressed files a JPEG marker is used instead of this tag. If this field does not exist, the TIFF default of 1 (chunky) is assumed. See remarks for further information.

Gets or sets the chromaticity of the three primary colors of the image. Constant length of 6.

Gets or sets the reference black point value and reference white point value. Constant length of 6.

Gets or sets the unit for measuring XResolution and YResolution. The same unit is used for both XResolution and YResolution. If the image resolution in unknown, 2 (inches) is designated. See remarks for further information.

Gets or sets number of rows per strip. This is the number of rows in the image of one strip when an image is divided into strips. With JPEG compressed data this designation is not needed and is omitted.

Gets or sets the number of components per pixel. Since this standard applies to RGB and YCbCr images, the value set for this tag is 3. In JPEG compressed data a JPEG marker is used instead of this tag.

Gets or sets the name and version of the software or firmware of the camera or image input device used to generate the image.

Gets or sets the total number of bytes in each strip. With JPEG compressed data this designation is not needed and is omitted. Constant length of SamplesPerPixel * StripsPerImage.

Gets or sets the byte offset of that strip. It is recommended that this be selected so the number of strip bytes does not exceed 64 Kbytes. With JPEG compressed data this designation is not needed and is omitted. Constant length of SamplesPerPixel * StripsPerImage.

Gets or sets a transfer function for the image, described in tabular style. Constant length of 3 * 256.

Gets or sets the chromaticity of the white point of the image. Constant length of 2.

Gets or sets the number of pixels per ResolutionUnit in the ImageWidth direction. When the image resolution is unknown, 72 [dpi] is designated.

Gets or sets the matrix coefficients for transformation from RGB to YCbCr image data. Constant length of 3.

Gets or sets position of chrominance components in relation to the luminance component. See remarks for further information.

Gets or sets the sampling ratio of chrominance components in relation to the luminance component. In JPEG compressed dat a JPEG marker is used instead of this tag. See remarks for further information.

Gets or sets the number of pixels per ResolutionUnit in the ImageHeight direction. When the image resolution is unknown, 72 [dpi] is designated.
