Filter Forge - x and y coordinates

Active Topics Search

jhantares Posts: 305 Filters: 272	As we know, the x and y coordinates should be in range 0-1. I tried this. Create a new filter, add script map component and ins ert error(x) or ...(y) after get_sample() as first entry. After starting the filter a negative value for x or y is shown. What's that?

If you were to start the image exactly at 0, any interpolations that would call for edge pixels might end up calling for pixels outside the bounds and create an artifact (line) at the seamless tiling edge if it wasn't done this way. Some such reason, I believe.
