Member Function Documentation

int lti::ioLTI::header::length

(

)

const [inline]

size of the header (in bytes)

bool lti::ioLTI::header::read

(

std::ifstream &

in

)

Member Data Documentation

union { ... }

Contents type:

• 0 : undefined
• 'b': ubyte channel
• 'i': int channel
• 'f': float channel
• 'c': rgbPixel image.

uint32 lti::ioLTI::header::columns

number of columns

ubyte lti::ioLTI::header::compression

Compression type:

• 0 : no compression
• 1 : runlength compression
• 2 : flate compression (only with zlib).

ubyte lti::ioLTI::header::contents

Contents type:

• 0 : undefined
• 'b': ubyte channel
• 'i': int channel
• 'f': float channel
• 'c': rgbPixel image.

const uint32 lti::ioLTI::header::reserved1

Must be 0 This can be used in the future to define some compressed formats.

const uint32 lti::ioLTI::header::reserved2

Must be 0 This can be used in the future to define some compressed formats.

uint32 lti::ioLTI::header::rows

number of rows

uint32 lti::ioLTI::header::size

file size in byte (excluding the header, so only the data section is counted).

const uint16 lti::ioLTI::header::type

file type.

For LTI-Types this must be 'LT'
