Tinct is a closed-source proprietary module that is best considered licence-encumbered abandonware. It cannot be updated to work properly on modern RISC OS hardware.
Anyone interested in developing a new efficient open-source sprite rendering module that can render sprites with alpha channels, and supports error diffusion for low bits-per-pixel screen modes should please get in touch.
Tinct provides RISC OS applications with support for high speed rendering of opaque and alpha-blended sprites with optional image enhancement. It was developed to enable NetSurf to plot PNGs with alpha channels and provide on-the-fly error diffusion to display images at their best in screen modes with few colours.

Please report any problems with this module directly to Richard Wilson.
