Brightens the color by dividing each RGB channel by 0.9. Channels with a value of 0 remain unaffected. Although brighter and darker are inverse operations, the results of a series of invocations will cause inconstancies due to rounding errors. Use More Light if you want to brighten up black areas as well.
Darkens the color by multiplying each RGB channel with 0.9. Although brighter and darker are inverse operations, the results of a series of invocations will cause inconstancies due to rounding errors. Less Light is usually a better option, because it operates in the HSL color space.
Desaturates the color by dividing the sum of the minimum and maximum channel values by two. Use Grayscale if you want something closer to the human perception of luminance.
Creates a grayscale version of the color(s) via the PAL/NTSC formula (0.299 * RED + 0.587 * GREEN + 0.114 * BLUE).
Converts to HSL color space, subtracts 0.05 from the hue, wraps if necessary, and converts it back to RGB again.
Converts to HSL color space, subtracts 0.05 from the lightness, clamps if necessary, and converts it back to RGB again.

Generate from Path
- Number of steps
Creates translucent copies of the path inside and outside the path.
Iterpolate does a linear interpolation between 2 or more paths. It basically means that it "fills in the gaps" between the paths according to the number of steps given.
To use the interpolation effect, select the paths that you wish to interpolate, and go to Effects > Generate From Path > Interpolate. Choose your options, and Click OK.
View figure 1 below, where there are 2 identical paths.
Here is the result when the interpolation effect is called with a "Steps" value of 6.
One of the great features of the inkscape interpolation is "transform style", which transforms the
It appears that you need to convert an object to a path first (Path > Object to path ; Shift-Ctrl-c). You can alter the number of steps used and choose one of two methods.
Pattern along Path
Star pattern and a line path:
Pattern along path:
- Copies of the pattern
- Deformation type
- Space between copies
- Normal offset
- Tangential offset
- Pattern is vertical
- Duplicate the pattern before deformation
- Deformation type
Color Markers to Match Stroke
- Maximum Displacement
- Shift Nodes
- Shift Node Handles
- Use Normal Distribution
- Font Size
- Dot Size
To use, select one path consisting of only line segments and apply the effect. Kochify will replace the given path with a path that has a copy of the original path in between each two adjacent nodes in the original path. If the original path input has bezier curves, the effect will effectively replace them with lines and then apply the effect. For more information about Kochify from a developers perspective, look here. Requires: python.
