generic accessor to write the tags from exif metadata.
When writing to an IFD 0 tag that is not a GPS tag, use KExifIfdZero.
When writing to a tag related to thumbnail, use KExifIfdOne.
When writing to a GPS tag, use KExifGpsIfd.
The TExifWriterUtility class offers a friendlier interface to access these tags.

Sets the data associated with an array of signed or unsigned 32-bit integers EXIF/DCF tag/IFD.
| Parameter | Description |
|---|---|
| aTag | the tag id where the data is stored |
| aIfd | the ifd section in which the tag is stored. |
| aParam | the list of values value for the tag |
Returns: error code KErrNotSupported if called on a decoding module. KErrNotSupported if the plugin does not support the specified tag. KErrArgument if the requested data type does not match with the tag.
Sets the data associated with a signed or unsigned 32-bit integer EXIF/DCF tag/IFD.
| Parameter | Description |
|---|---|
| aTag | the tag id where the data is stored |
| aIfd | the ifd section in which the tag is stored. |
| aParam | the value of the tag |
Returns: error code KErrNotSupported if called on a decoding module. KErrNotSupported if the plugin does not support the specified tag. KErrArgument if the requested data type does not match with the tag.
Set 16-bit Unicode data into EXIF/DCF tag/IFDs that support it (e.g.0x9286 (UserComment), 0x001B (GpsProcessingMethod) or 0x001C (GpsAreaInformation) ).
Note: This method will add the 8-byte prefix "UNICODE/0" to aParam before setting the tag value in the metadata. It may only be used to set Unicode data.
| Parameter | Description |
|---|---|
| aTag | the tag id where the data is stored |
| aIfd | the ifd section in which the tag is stored. |
| aParam | the value of the tag |
Returns: error code KErrNotSupported if called on a decoding module. KErrNotSupported if the plugin does not support the specified tag. KErrArgument if the requested data type does not match with the tag.
Set the data associated with an 8-bit (e.g. ASCII, Undefined or Byte) EXIF/DCF tag/IFD.
Note: If setting non-NULL terminated ASCII data, this method will add a NULL terminator to it provided that doing so will not cause the length of the tag value to be exceeded. If the length would be exceeded KErrArgument will be returned.
Note: This method will set other (non-ASCII) 8-bit data exactly as-is.
| Parameter | Description |
|---|---|
| aTag | the tag id where the data is stored |
| aIfd | the ifd section in which the tag is stored. |
| aParam | the value of the tag |
Returns: error code KErrNotSupported if called on a decoding module. KErrNotSupported if the plugin does not support the specified tag. KErrArgument if the requested data type does not match with the tag.
Sets the data associated with an array of signed or unsigned rationals EXIF/DCF tag/IFD.
| Parameter | Description |
|---|---|
| aTag | the tag id where the data is stored |
| aIfd | the ifd section in which the tag is stored. |
| aParam | the list of values value for the tag |
Returns: error code KErrNotSupported if called on a decoding module. KErrNotSupported if the plugin does not support the specified tag. KErrArgument if the requested data type does not match with the tag.
Sets the data associated with a signed or unsigned rational EXIF/DCF tag/IFD.
| Parameter | Description |
|---|---|
| aTag | the tag id where the data is stored |
| aIfd | the ifd section in which the tag is stored. |
| aNumerator | the numerator value of the rational tag |
| aDenominator | the denominator value of the rational tag |
Returns: error code KErrNotSupported if called on a decoding module. KErrNotSupported if the plugin does not support the specified tag. KErrArgument if the requested data type does not match with the tag.
Sets the data associated with an array of unsigned short (16-bit) EXIF/DCF tag/IFD.
| Parameter | Description |
|---|---|
| aTag | the tag id where the data is stored |
| aIfd | the ifd section in which the tag is stored. |
| aParam | the list of values value for the tag |
Returns: error code KErrNotSupported if called on a decoding module. KErrNotSupported if the plugin does not support the specified tag. KErrArgument if the requested data type does not match with the tag.
Sets the data associated with an unsigned short (16-bit) EXIF/DCF tag/IFD.
| Parameter | Description |
|---|---|
| aTag | the tag id where the data is stored |
| aIfd | the ifd section in which the tag is stored. |
| aParam | the value of the tag |
Returns: error code KErrNotSupported if called on a decoding module. KErrNotSupported if the plugin does not support the specified tag. KErrArgument if the requested data type does not match with the tag.
