# This class allows the creation of a RgImage object. The parameters that need to be set are
|
|
#\verbatim
|
|
#WIDTH: width of the image in units of the DATA_TYPE. Mandatory.
|
|
#FILE_NAME: name of the file containing the image. Mandatory.
|
|
#DATA_TYPE: data type used to store the image. The naming convention is the one adopted by numpy (see LineAccessor class). Optional. Default value 'BYTE'.
|
|
#ACCESS_MODE: access mode of the file such as 'read', 'write' etc. See LineAccessor class for all possible values. Mandatory.
|
|
#SCHEME: the interleaving scheme adopted for the image. Could be BIL (band interleaved by line), BIP (band intereleaved by pixel) and BSQ (band sequential). Optional. BIP set by default.
|
|
#CASTER: define the type of caster. For example DoubleToFloat reads the image data as double but puts it into a buffer that is of float type. Optional. If not provided casting is not performed.
|
|
#\endverbatim
|
|
#Since the RgImage class inherits the Image.Image, the methods of initialization described in the Component package can be used.
|
|
#Moreover each parameter can be set with the corresponding accessor method setParameter() (see the class member methods).
|
|
#@see DataAccessor.Image.
|
|
#@see Component.Component.
