Description copied from class: ImageDataReader

Defines a method for accessing the floating-point raster data in a TIFF image. These implementations of this method in DataReaderStrips and DataReaderTiled assume that this instance is of a compatible data type (floating-point) and that all access checks have already been performed.

Specified by:

readRasterData in class ImageDataReader

Parameters:

subImage - if non-null, instructs the access method to retrieve only a sub-section of the image data.

Returns:

a valid instance

Throws:

ImageReadException - in the event of an incompatible data form.

java.io.IOException - in the event of I/O error.
