+Screentone
+    .. versionadded:: 4.3.1
+
+    Fills the layer with simple regular patterns like dots and lines like the ones used in traditional `screentone <https://en.wikipedia.org/wiki/Screentone>`_ or `halftone <https://en.wikipedia.org/wiki/Halftone>`_ techniques.
+
+    Screentone Type
+        Pattern
+            Select the global appearance (dots, lines).
+        Shape
+            Select the specific appearance of the pattern (for example: round dots, diamond dots, straight lines, sine wave lines).
+        Interpolation
+            Select how the pattern transitions from the foreground to the background.
+
+            In most cases but the dot pattern with round shape combination, the effect of the interpolation mode is not very noticeable.
+
+        .. figure:: /images/layers/fill_layer_screentone_type.png
+
+            From left to right, top to bottom: 
+            dot pattern with round shape, dot pattern with ellipse shape, 
+            dot pattern with diamond shape, dot pattern with square shape, 
+            line pattern with straight shape, line pattern with sine wave shape, line pattern with triangular wave shape, 
+            line pattern with sawtooth wave shape and line pattern with curtain shape.
+
+    Transformation
+        Select how the pattern is arranged geometrically in the image (position, size, rotation, shear).  
+        Some patterns benefit from the capability of choosing horizontal and vertical sizes separatelly. For example, the sin wave lines pattern has a small period by default and by choosing a large horizontal size the period will look also larger.

+        .. figure:: /images/layers/fill_layer_screentone_transformation.png
+
+            From left to right: 
+            dot pattern with round shape without rotation, dot pattern with round shape and rotated 45 degrees, 
+            line pattern with sine wave shape and a size of 20px horizontally and vertically, 
+            line pattern with sine wave shape and a size of 50px horizontally and 20px vertically.
+
+    Postprocessing
+        Background & Foreground
+            Allows you to choose the color and opacity of the foreground (dots, lines) and the background.
+        Invert
+            This flips what is treated as foreground and background.
+        Brightness & Contrast
+            The brightness controls how close to the foreground or background color the pattern apperars (how *dark* or *light* in the case of black foreground and white background). 
+            So if you want to simulate small dots, for example, set the brightness to a high value and to obtain big dots set it to a low value.
+            
+            The contrast controls how smooth or sharp is the transition between the foreground and background colors. By default the contrast is set to 50% (smooth). 
+            To achieve the typical sharp borders the contrast must be set to a higher value.
