Solid Noise cloud in an automatically created new layer, and sets the layer mode to Difference, then merges this layer over the specified image.
command changes colors partially in cloud-like areas: The filter rendersIf the image is in indexed colors, this menu entry is disabled.
This option controls the randomness of the filter. The Random seed box lets you manually enter a seed for the randomization algorithm used. A different random seed produces different results.
This controls the level of detail in the noise texture. Higher values give a higher level of detail, and the noise seems to be made of spray or small particles, which makes it feel hard. A low value makes it more soft and cloudy.
If you check Tileable, you'll get a noise that can be tiled seamlessly in a grid. The left edge will align seamlessly with the right edge, and the top edge will align seamlessly with the bottom edge. Only the generated noise is tileable. The underlying image is not modified to be tileable.
If you check this, you'll get very interesting effects, often something that looks much like oil on water, or clouds of smoke, or living tissue, or a Rorschach blot.
These control the size and proportion of the noise shapes in X (horizontal) and Y (vertical) directions (range 0.1 to 16.0).
