# Usage
|| *parameter* || *value* || *description* ||
|| opacity || 0.0 - 1.0 || 1 is fully opaque while zero is fully transparent and .5 would be 50% transparent ||
|| mode || grain_merge, grain_merge2, multiply, multiply2, divide, divide2, screen, hard_light || Compositing/Merging effects with image below raster level (?). The formulas for combinding foreground (raster) and background are: grain_merge: bg + fg - 0.5, grain_merge2: bg + 2*fg - 1.0, multiply: fg * bg, multiply2: 2 * fg * bg, divide: bg / fg, divide2: 2*bg / fg, screen: (1-fg)*(1-bg), hardlight: see [[http://docs.gimp.org/en/gimp-concepts-layer-modes.html#id2834930]] ||
|| scaling || fast, bilinear, bilinear8 || fast: nearest neighbour, bilinear: bilinear interpolation for all 4 channels (RGBA), bilinear8 like bilinear, but only one channel assumed ||
