The lower the rate, the quicker the color gets added. .. index:: Mirror .. _option_mirror: Mirror ------ .. image:: /images/en/Krita_Pixel_Brush_Settings_Mirror.png This allows you to mirror the Brush-tip with Sensors. Horizontal Mirrors the mask horizontally. Vertical Mirrors the mask vertically. .. image:: /images/en/Krita_2_9_brushengine_mirror.jpg Some examples of mirroring and using it in combination with :ref:`option_rotation`. .. _option_rotation: Rotation -------- This allows you to affect Angle of your brush-tip with Sensors. .. image:: /images/en/Krita_2_9_brushengine_rotation.png .. image:: /images/en/Krita_Pixel_Brush_Settings_Rotation.png In the above example, several applications of the parameter. #. Drawing Angle -- A common one, usually used in combination with rake-type brushes. Especially effect because it does not rely on tablet-specific sensors. Sometimes, Tilt-Direction or Rotation is used to achieve a similar-more tablet focused effect, where with Tilt the 0° is at 12 o'clock, Drawing angle uses 3 o'clock as 0°. #. Fuzzy -- Also very common, this gives a nice bit of randomness for texture. #. Distance -- With careful editing of the Sensor curve, you can create nice patterns. #. Fade -- This slowly fades the rotation from one into another. #. Pressure -- An interesting one that can create an alternative looking line. .. _option_scatter: Scatter ------- This parameter allows you to set the random placing of a brush-dab. You can affect them with Sensors. X The scattering on the angle you are drawing from. Y The scattering, perpendicular to the drawing angle (has the most effect) .. image:: /images/en/Krita_2_9_brushengine_scatter.png .. _option_sharpness: Sharpness --------- .. image:: /images/en/Krita_Pixel_Brush_Settings_Sharpness.png -Puts a threshold filter over the brush mask. +Puts a threshold filter over the brush mask. This can be used for brush like strokes, but it also makes for good pixel art brushes. + +Strength + Controls the threshold, and can be controled by the sensors below. +Softness + Controls the extra non-fully opaque pixels. This adds a little softness to the stroke. + +.. versionchanged:: 4.2 + + The sensors now control the threshold instead of the subpixel precision, softness slider was added. .. _option_size: Size ---- .. image:: /images/en/Krita_Pixel_Brush_Settings_Size.png This parameter is not the diameter itself, but rather the curve for how it's affected. So, if you want to lock the diameter of the brush, lock the Brush-tip. Locking the size parameter will only lock this curve. Allowing this curve to be affected by the Sensors can be very useful to get the right kind of brush. For example, if you have trouble drawing fine lines, try to use a concave curve set to pressure. That way you'll have to press hard for thick lines. .. image:: /images/en/Krita_2_9_brushengine_size_01.png Also popular is setting the size to the sensor fuzzy or perspective, with the later in combination with a :ref:`assistant_perspective` .. image:: /images/en/Krita_2_9_brushengine_size_02.png .. _option_softness: Softness -------- This allows you to affect Fade with Sensors. .. image:: /images/en/Krita_2_9_brushengine_softness.png Has a slight brush-decreasing effect, especially noticeable with soft-brush, and is overall more noticeable on large brushes. .. _option_source: Source ------ Picks the source-color for the brush-dab. Plain Color Current foreground color. Gradient Picks active gradient Uniform Random Gives a random color to each brush dab. Total Random Random noise pattern is now painted. Pattern Uses active pattern, but alignment is different per stroke. Locked Pattern Locks the pattern to the brushdab .. _option_mix: Mix --- Allows you to affect the mix of the :ref:`option_source` color with Sensors. It will work with Plain Color and Gradient as source. If Plain Color is selected as source, it will mix between foreground and background colors selected in color picker. If Gradient is selected, it chooses a point on the gradient to use as painting color according to the sensors selected. .. image:: /images/en/Krita_2_9_brushengine_mix_01.png Uses ~~~~ .. image:: /images/en/Krita_2_9_brushengine_mix_02.png Flow map The above example uses a :program:`Krita` painted flowmap in the 3D program :program:`Blender`. A brush was set to :menuselection:`Source --> Gradient` and :menuselection:`Mix --> Drawing angle`. The gradient in question contained the 360° for normal map colors. Flow maps are used in several Shaders, such as brushed metal, hair and certain river-shaders. .. _option_gradient: Gradient ~~~~~~~~ Exactly the same as using :menuselection:`Source --> Gradient` with :guilabel:`Mix`, but only available for the Color Smudge Brush. .. index:: Spacing .. _option_spacing: Spacing ------- .. image:: /images/en/Krita_Pixel_Brush_Settings_Spacing.png This allows you to affect :ref:`option_brush_tip` with :ref:`sensors`. .. image:: /images/en/Krita_2_9_brushengine_spacing_02.png Isotropic spacing Instead of the spacing being related to the ratio of the brush, it will be on diameter only. .. image:: /images/en/Krita_2_9_brushengine_spacing_01.png .. index:: Ratio .. _option_ratio: Ratio ----- Allows you to change the ratio of the brush and bind it to parameters. This also works for predefined brushes. .. image:: /images/en/Krita_3_0_1_Brush_engine_ratio.png
