Properties
- AlphaMode
Specifies the alpha mode for the input, and for the output. The default value is Premultiplied.
- Angle
Specifies the angle of the screen, in degrees. The default value is 0. In Cmyk the four inks sit at the traditional 15, 75, 0 and 45 degrees, and this turns all of them together: it rotates the whole rosette while leaving the relationships between the screens intact. In Monochrome it turns the single screen, which sits on black's 45.
- BlackGeneration
Specifies how much of the ink that could go into black actually does. At 1 every bit of neutral ink is carried by the black screen; at 0 it is built out of cyan, magenta and yellow together. The range is [0, 1], the default is 0.75. Ignored when ColorMode is set to Monochrome. Tone-neutral by construction, but it decides whether the result reads as a rosette - at 1 the chromatic screens carry nothing neutral and there is none - and it costs accuracy in the deep shadows, where near-closed shapes leave a sliver at each cell corner whose rendered area depends on the screen's angle.
- CellSize
Specifies the screen ruling, in pixels: the distance from one cell to the next. The range is [2, 200], the default is 8.
- ColorMode
Specifies whether the image is separated into four process-color inks on four grids, or screened with a single black ink on one. The default value is Cmyk.
- GridOrigin
Specifies the point, in the input's own coordinate space, that every screen puts a cell centre exactly on. The default value is { 0, 0 }, but usually this is set to the center point of the image or selected area.
- InputColorContext
Specifies the color context of the Input image, which is used to optimize the quality of this effect's rendering.
- Pattern
Specifies the shape that is laid down in each cell of the screen. The default value is Dots.
- Quality
Specifies how many jittered samples of the screen each output pixel averages: the square of this value. The range is [1, 8], the default is 2. The shapes are rendered with hard edges, so this controls antialiasing. A value of 1 produces aliased output.
- Softness
Specifies how soft the edge of each shape is. At 0 there is no transition beyond what Quality antialiases; at 1 it grows with CellSize, dissolving the shapes into soft blobs at any ruling. The range is [0, 1], the default is 0.
