Detailed Description

Base class to functors which load and save images in LTI format.

The LTI format is a raw data file, in which only size of the image and the data, without any compression type (yet), are stored.

It is necessary because standard file formats do not provide functionaly to save floating-point or integer (32 bit) channels.

See also:

lti::ioLTI::parameters

lti::ioLTI::header

This functor is at a very primitive development stage. The format will change in the future, mainly because at this time, it depends on the implemented platform, i.e. maybe a file stored on Linux won't be readable on Windows and vice-versa. Endianness and floating point number format still need to be formally specified.

It is although provided for those applications which need to store imatrices or channels, for which no other alternative is provided.

Member Enumeration Documentation

enum lti::ioLTI::eCompressionType

The compression methods usable for compressing the data.

You should be aware that runlength compression makes only sense with matrices of bytes. RunLength tries to find runs of equal bytes, which basically never happens in matrices of elements that occupy more than one byte.

Enumerator:

None	use no compression
RunLength	uses runlength compression
Flate	uses zLib deflate compression

Member Function Documentation

const parameters& lti::ioLTI::getParameters

(

)

const

returns current parameters.

Reimplemented from lti::ioFunctor.

virtual const char* lti::ioLTI::getTypeName

(

)

const [virtual]

returns the name of this type

Reimplemented from lti::ioFunctor.

Reimplemented in lti::loadLTI, and lti::saveLTI.

virtual bool lti::ioLTI::updateParameters

(

)

[virtual]

set functor's parameters.

This member makes a copy of theParam: the functor will keep its own copy of the parameters. Furthermore, the method will create the appropriate compression codec from the parameters compression value.

Returns:

true if successful, false otherwise

Reimplemented from lti::functor.
