# STP : Semi-Transparency usage
This example shows the effect of activating Semi-Transparency on a textured primitive.
Use the `SELECT` button to switch primitive semi-transparency on and off.
Use the `START` button to cycle throught the 4 transparency rates.
It also features a few C struct to facilitate access to the TIM file / pixel data.
See [here](https://github.com/ABelliqueux/nolibgs_hello_worlds/tree/main/hello_poly_stp) for more information on how to convert your images to TIM while preserving transparency.
