NTI specification

NTI (Enhanced TI.Image) is an extremely simple array-based image format supported by nSDL. An image converter is available in nSDL's tools folder or by direct download here (requires .NET Framework 4).

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; should be 42) and version (low byte).
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.
