Color:
Grayscale: Equivalent to de-color
brighter and darker: This feeling is not easy to use unless it is a very complex color. Otherwise you can copy the original graphic, and set a gray mask with high transparency is more convenient.
Negative: negative negative effect,
Randomize: Random, optional hue hue. Saturation of the saturation. Lightness brightness. Sometimes it can be used as a lazy way to avoid color. Or you can use it when you're making a psychedelic/cyberpunk style, and you might have a surprise.
Replace: replaces the color. (The name can be right-click the same color Ah, this a bit six)
Extrude deformation
Extension→generate from Path→extrude
3d objects can be created for two paths (the graphic requires CTRL + Shift +C to be converted to a path).
Strictly speaking, the two paths are rectangular and very useful. But when the path is circular, it essentially constructs 3D as a rectangular polygon of two faces of a circle. As a result, only four lines are obtained for two circular path operations (such as line). It's not the same as the original idea of Balabala.
Interpolate interpolation
This function must be learned well. Because the AI also has a corresponding function, and a lot of cool effects can be achieved through this.
Extension→generate from Path→interpolate
Select two objects (paths) to perform the above actions.
Covert dash to dash of path converts style of stroke to path
Extension→generate from Path→convert to dashes
Anything in the real sense can be "moved".
Envelope and Perspective nested perspective
1 This is only valid for paths.
2 The Pivot object that is used for nesting must be made up of Four Corners + four straight lines.
3 Select the object to deform the perspective and provide a nested perspective object (template).
4 extension→modify Path
Barcode Generating Barcodes
Extension→render→barcode
There are three kinds, classic (barcode) Datamatrix (a matrix code commonly used for anti-counterfeiting) QR code (this is used widely, can be used to open a website)
(from this point of view, Inkscape as an open-source design tool to adapt to the needs of the warm, under the deeply moved)
