Boolean Operation

The Boolean Operation in Incari provides similar functionality as its equivalent in Figma. It acts as parent to its child Objects. Any visual aspects are controlled completely by the Boolean Operation; the visual properties of the children do not have any precendent, such as a child's Fill.
There are several Attributes which allow the user heightened customizability and control.
The Transformation Attributes deal with placement, rotation, and size in XY space. More information can be found here.
This Attribute lets the user set a Blend Mode as a base property of the Ellipse. These are established on common formulas, examples of each can be accessed here. An Object's Blend Mode can also be set with the Set Blend Mode Node.
The Fill Attributes consist of different items called Elements. Each Element contains a Type. This can be either Solid or Image and changes some of the available Attributes under this category.
If there is more than one Fill Element, the most recent one will take precedent over the others (unless some Blend Mode is applied).
When Solid is selected, Color is visible.
Color is a color selector that lets the user pick the Fill's color.
Similar to the base property described previously, Blend Mode here affects the Fill Elements only. These are established on common formulas, examples of each can be accessed here. It can also be set with the Set Blend Mode Node.
Opacity refers to how opaque or transparent the Fill appears. This is represented by an integer between 0 and 1.
When Image is selected, Image and Fit Mode are visible.
Image is the desired Texture file.
Fit Mode determines how the Texture is displayed. These can be Fill, Fit, Crop, and Tile. Tile has the additional Attribute of Scale Factor, which augments the tesselation.

The Stroke Attributes consist of different items called Elements. Each Element contains a Type. This can be either Solid or Image and changes some of the available Attributes under this category. There are also two fixed Attributes outside of the Elements. These are:
Width, which is how wide (in pixels) each Stroke will appear. This applies to each Stroke Element.
Position, which determines what part of the outline identifies the outside of the Object. For example, if Inner is selected, then the outside of the Stroke is the outside of the Object. If Center is selected, then the Stroke's center is the outside of the Object. If Outer is selected, then the inside of the Stroke is the outside of the Object.
When Solid is selected, Color is visible.
Color is a color selector that lets the user pick the Stroke's color.

Image is the desired Texture file.

A Mask is an Object that shows a certain area of another Object while concealing the rest. Any Object (e.g., an Ellipse, Rectangle, Frame, Group, or Text) can be used as a Mask.
For easier visualization, think of the Mask as a cookie cutter while the masked Object is the dough: the cookie cutter shows only a part and discards the rest.
The Type Attribute has three options:
None - nothing is applied.
Alpha - the Mask has an opacity level (alpha channel) determining with which level of opacity (or transparency) the masked Object is revealed: 0% opacity reveals nothing, 100% opacity is equivalent to a Mask with Vector type.
Vector - only modifies the shape outline of the masked Object
Luminance - allows the user to utilize brightness to determine the effect of the Mask; the brighter the area of a Mask, the more that is revealed and the darker the area, the less that is revealed.
Object allows the user to select what should be the masked Object.
Apply Mask is a toggle that applies the Mask when set to on, and disables the Mask when set to off.
The Operation Attribute implements the four functions:
Thie child Objects form the shape that will be the core of what is displayed throught the different operations. The base Object is always the last child Object in the Scene Outliner. In the image below, the base Object is the Rectangle.
Exclude displays all child Objects but removes any overlapping parts of other children from the base Object. Since the Rectangle is the base Object in the example above, the overlapping section of the Ellipse (the other child Object) is removed.
Intersect displays only the parts of the other children Objects which overlap with the base Object. Here, the top-left quadrant of the Ellipse (which is represented by the right bounding box) overlaps with the Rectangle (which is represented by the left bounding box). Their intersection remains visible.
Subtract removes the base Object completely, even the parts which overlap with the other children. Since the Rectangle is the base Object in the example above and it's bottom-right quarter overlaps the Ellipse, this is removed as well.
Union combines all children as a single Object. In this example, there are only two Objects: an Ellipse and a Rectangle. There are no separating lines anymore and both take the color given to the Boolean Operation (in this case, red).
This Attribute manages the tags for the Button. See more on tags here.
