readRasterData
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 classImageDataReader
- 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.IOException
- in the event of I/O error.
