MyPaint Brush Engine

../../../_images/mypaintbrush.svg

MyPaint is a free painting program that comes with a lot of specific brushes. Krita can use those brushes for painting using the MyPaint brush engine.

Opozorilo

You can create new brush presets using the MyPaint brush engine in Krita, but the presets are saved in Krita’s .kpp file format, not mypaints .myb format, so you cannot reuse those presets in MyPaint.

Dinamični vhodi

Dynamic Inputs are a way for MyPaint to get information of the external devices as a drawing tablet; for instance the pressure over the drawing tablet, the speed of pencil movement, the pencil tilt .. etc. They are equivalent to Tipala in Krita.

MyPaint ima 9 vhodov:

  • Pritisk

    The pressure handled by a tablet. Typically in the range 0.0 to 1.0.

  • Fina hitrost

    How quickly the stylus is moving. This can vary quite a lot.

  • Groba hitrost

    Podobno kot pri fini hitrosti, vendar se spreminja zelo počasi.

  • Naključno

    Hiter in naključen šum, spreminja se z vsako potezo čopiča.

  • Poteza

    This input goes slowly from 0.0 to 1.0 while the stroke is being applied. This is related to „stroke duration“ and „stroke holdtime“ settings.

  • Smer

    This input defines the angle of a stroke, in degrees.

  • Spust

    This input defines the declination of the stylus tilt. This is the same as tilt-elevation in Krita.

  • Dvig

    Straight pen ascension. When the active tip points to it, it is 0. When the pen turns 90 degrees clockwise is +90. When it turns 90 degrees counterclockwise is -90. This is the same as tilt-direction in Krita.

  • Po meri

    This is a user-defined input. It is related to the „customized input“ setting.

Parametri

Ima naslednje parametre:

Osnovno

Polmer

This is to set the radius of the brush. Please note that all of the mypaint radii are logarithmic. For instance, if you are setting the radius of a preset to say, 2.0 then the actual radius of the preset is going to be e^(2.0) which is equal to 7.389. This makes the size of the brush equal to 14.78. So, we can say that mypaint_radius = log(actual_radius).

Trdota

Hardness defines the sharpness of the brushes.

Radirka

If this option is checked the brush will act as an eraser.

Naključni polmer

This option is used to generate a brush preset whose radii and opacity change randomly during the stroke. This should not be confused with the random dynamic option in the radius setting.

Glajenje robov

This option is used to smoothen the edges of the brush and remove the jagging effect. Most useful for very small presets.

Elliptical Dab: Angle

Sets the angle of the brush dabs. Gives the best results for brushes with a low ratio and a direction filter, and allows for strokes akin to a calligraphic pen.

Elliptical Dab: Ratio

This option is used to change the aspect ratio of dab.

Filter smeri

This option is used to make the dabs adhere to a specific vector direction. In simple words, at times you might find the dabs not following the vector path of your strokes, this setting helps us rectify that.

Barva

Change color Hue

This option is used to shift the hue in a clockwise or anti-clockwise direction.

Change color Lightness

This option is used to change color luminance using the HSL color model.

Change color Value

This option is used to change color value (brightness, intensity) in HSV color model.

Change color Saturation HSL

This option is used to change color saturation using HSL color model.

Change color Saturation HSV

This option is used to change color saturation using HSV color model.

Hitrost

Gama fine hitrosti

This option is used to change the reaction of the fine speed input to extreme physical speed.

Gama grobe hitrosti

This option is used to change the reaction of gross speed to extreme physical speed.

Fine Speed Slowness / Fine Speed Filter

This option describes how slow the input fine speed is following the real speed.

Gross Speed Slowness / Gross Speed Filter

This option describes how slow the input gross speed is following the real speed.

Odmik s hitrostjo

This option is used to change the position of dabs based on stroke speed.

Offset By Random [Jitter]

This option adds a random offset to the position where each dab is drawn.

Pivnanja

Pivnanj na dejanski polmer

This option describes how many dabs to draw when the pointer moves the distance of the brush radius.

Pivnanj na sekundo

This option describes how many dabs to draw per second irrespective of any other parameter.

Prekrivnost

Neprozorno

Opaque describe the translucency or transparency of mypaint brushes.

Neprosojno lineariziraj

This option lets you correct the nonlinearity introduced by blending multiple dabs on top of each other.

Množena prekrivnost

This makes opacity depend on pressure.

Sledenje

Počasno sledenje

Slow pointer tracking speed. Higher values remove jitter in cursor movements. Useful for drawing smooth outlines.

Počasno sledenje na pivnanje

Similar to above but at a brushdab level.

Sledilni šum

Add randomness to the mouse pointer. This usually generates many small lines in random directions.

Razmaži

Razmaži

This option lets you smudge, by picking a color from the canvas and mixing this with the brush color. The color slowly changes to the color you are painting on.

Dolžina razmaza

This option controls how much the painting color is mixed with the colors from the canvas.

Smudge Radius logarithmic

This option modifies the radius of the circle where the color is picked up for smudging.

Poteza

Stroke Duration logarithmic

This option describes how far you have to move until the stroke input becomes 1.0

Čas zadržanja poteze

This option defines how long the stroke input stays at 1.0. After that it will go back towards 0.0 and then start increasing again.

Prag poteze

This option defines how much pressure is needed to start the stroke. This affects stroke input only. The MyPaint brush engine does not need any minimum pressure level to start drawing.

Vnos po meri

Vnos po meri

The idea of this input is that you make this input depend on a mixture of pressure/speed/whatever, and then make other settings depend on this ‚custom input‘ instead of repeating this combination everywhere you need.

Počasnost vnosa po meri

This option defines how slow the custom input setting actually follows the desired value.
