NTI specification

NTI images

NTI (Enhanced TI.Image) is an extremely simple array-based image format supported by nSDL.

Header

An NTI image is stored in a single array of unsigned 16-bit values. It always starts with an 8-byte header containing 4 values:

Index	Description
0	Magic number (high byte) and version (low byte), should be 0x2A01.
1	Image width.
2	Image height.
3	Reserved, should be 0x0000.

All integers are 2 bytes long in big endian order. Their values can never exceed 2¹⁶−1 since they are read as unsigned shorts.

Pixel data

Every pixel is stored in 16-bit high color format from array index 4 onward.
