Halftone -------- .. image:: /images/filters/Krita_halftone_filter.png The halftone filter is a filter that converts the colors to a halftone dot pattern. Colors The colors used to paint the pattern. The first is the color of the dots, the second the color of the background. Size The size of the cell in pixels. The maximum dot size will be using the diagonal as the cell size to make sure you can have pure black. Angle The angle of the dot pattern. Invert This inverts the intensity calculated per dot. Thus, dark colors will give tiny dots, and light colors big dots. This is useful in combination with inverting the colors, and give a better pattern on glowy-effects. Anti-aliasing This makes the dots smooth, which is good for webgraphics. Sometimes, for print graphics, we want there to be no grays, so we turn off the anti-aliasing. Index Color ----------- The index color filter maps specific user selected colors to the grayscale value of the artwork. You can see the example below, the strip below the black and white gradient has index color applied to it so that the black and white gradient gets the color selected to different values. .. image:: /images/common-workflows/Gradient-pixelart.png You can choose the required colors and ramps in the index color filter dialog as shown below .. image:: /images/filters/Index-color-filter.png You can create index painting such as one shown below with the help of this filter .. image:: /images/common-workflows/Kiki-pixel-art.png Pixelize -------- Makes the input-image pixely by creating small cells and inputting an average color. .. image:: /images/filters/Pixelize-filter.png Raindrops --------- Adds random raindrop-deformations to the input-image. Oilpaint -------- Does semi-posterisation to the input-image, with the 'brush-size' determining the size of the fields. .. image:: /images/filters/Oilpaint-filter.png Brush-size Determines how large the individual patches are. The lower, the more detailed. Smoothness Determines how much each patch's outline is smoothed out. Posterize --------- This filter decreases the amount of colors in an image. It does this per component (channel). .. image:: /images/filters/Posterize-filter.png The :guilabel:`Steps` parameter determines how many colors are allowed per component.
