Describes the layout of a section of IDTF.

Fields

ilda: [u8; 4]

The ASCII letters ILDA, identifying an ILDA format header.

reserved: [u8; 3]

Reserved for future use. Must be zeroed.

format: Format

One of the format codes defined in the Format Codes section.

data_name: Name

Eight ASCII characters with the name of this frame or color palette. If abinary zero is encountered, than any characters following the zero SHALL be ignored.

company_name: Name

Eight ASCII characters with the name of the company who created theframe. If a binary zero is encountered, than any characters following the zero SHALL beignored.

num_records: U16<Endianness>

Total number of data records (points or colors) that will follow this headerexpressed as an unsigned integer (0 – 65535). If the number of records is 0, then this is to be taken as the end of file header and nomore data will follow this header. For color palettes, the number of records SHALL be between 2 and 256.

data_number: U16<Endianness>

Frame or color palette number. If the frame is part of a group such as an animation sequence, thisrepresents the frame number. Counting begins with frame 0. Range is 0 – 65534.

color_or_total_frames: U16<Endianness>

Total frames in this group or sequence. Range is 1 – 65535.

For colorpalettes this SHALL be 0.

projector_number: u8

The projector number that this frame is to be displayed on. Range is 0 – 255. For single projector files this SHOULD be set 0.

reserved2: u8

Reserved for future use. Must be zeroed.
