Get the data associated with an array of signed or unsigned 32-bit integers EXIF/DCF tag/IFD. If being used to get unsigned integers, it is up to the caller to typecast them as appropriate.

Note: aParam will be resized to fit the number of data elements read.

error code KErrArgument if the requested data type does not match with the tag. KErrNotSupported if called on an encoding module. KErrNotFound if the tag cannot be found.

Get the data associated with a signed or unsigned 32-bit integer EXIF/DCF tag/IFD. If used to get unsigned data, it is up to the caller to do the appropriate typecast of aParam.

error code KErrArgument if the requested data type does not match with the tag. KErrNotSupported if called on an encoding module. KErrNotFound if the tag cannot be found.

Get the data associated with a 16-bit EXIF/DCF tag/IFD.

Ownership of the buffer pointed to by aParam transfers to the client, which is therefore responsible for deleting the buffer when required.

Note: The client should always initialise aParam to NULL, and the plugin should only assign to this parameter when ready to transfer ownership.

Note: This method is not recommended. To get 16-bit data from a tag of undefined type, it is recommended that GetParam8() be used instead. The HBufC8* returned by GetParam8() can then be converted into an HBufC16* as needed.

error code KErrArgument if the requested data type does not match with the tag. KErrNotSupported if called on an encoding module. KErrNotFound if the tag cannot be found.

Get the data associated with an 8-bit (e.g. ASCII, Undefined or Byte) EXIF/DCF tag/IFD.

Ownership of the buffer pointed to by aParam transfers to the client, which is therefore responsible for deleting the buffer when required.

Note: The client should always initialise aParam to NULL, and the plugin should only assign to this parameter when ready to transfer ownership.

Note: If using this method to retrieve ASCII data, the returned data will not be NULL terminated.

Note: If using this method to retrieve Undefined data, the raw data will be returned, exactly as it appears in the tag value. Thus if the tag is one that includes a character code prefix, then this prefix will be included in the returned data. See table 6 of the Exif 2.2 specification for a list of character code prefixes.

error code KErrArgument if the requested data type does not match with the tag. KErrNotSupported if called on an encoding module. KErrNotFound if the tag cannot be found.

Get the data associated with an array of signed or unsigned rationals EXIF/DCF tag/IFD. If used to get unsigned rational data, it is up to the client to typecast the components as appropriate.

Note: aParam will be resized to fit the number of data elements read.

error code KErrArgument if the requested data type does not match with the tag. KErrNotSupported if called on an encoding module. KErrNotFound if the tag cannot be found.

Get the data associated with a signed or unsigned rational EXIF/DCF tag/IFD. If used to get an unsigned rational, it is up to the caller to typecast aNumer & aDenom as appropriate.

error code KErrArgument if the requested data type does not match with the tag. KErrNotSupported if called on an encoding module. KErrNotFound if the tag cannot be found.

Get the data associated with an array of unsigned short (16-bit) integers EXIF/DCF tag/IFD.

Note: aParam will be resized to fit the number of data elements read.

error code KErrArgument if the requested data type does not match with the tag. KErrNotSupported if called on an encoding module. KErrNotFound if the tag cannot be found.

Get the data associated with an unsigned short (16-bit) integer EXIF/DCF tag/IFD.

error code KErrArgument if the requested data type does not match with the tag. KErrNotSupported if called on an encoding module. KErrNotFound if the tag cannot be found.
