Constructors

constructor

public override new Latexprops: LatexProps: Latex

Parameters

Overwrites Img.constructor

Properties

absolutePosition

A helper signal for operating on the position in world space.

Retrieving the position using this signal returns the position in world space. Similarly, setting the position using this signal transforms the new value to local space.

If the new value is a function, the position of this node will be continuously updated to always match the position returned by the function. This can be useful to "pin" the node in a specific place or to make it follow another node's position.

Unlike position, this signal is not compound - it doesn't contain separate signals for the x and y components.

Inherited from Img.absolutePosition

absoluteRotation

readonly public absoluteRotation: SimpleSignalnumberLatex

A helper signal for operating on the rotation in world space.

Retrieving the rotation using this signal returns the rotation in world space. Similarly, setting the rotation using this signal transforms the new value to local space.

If the new value is a function, the rotation of this node will be continuously updated to always match the rotation returned by the function.

Inherited from Img.absoluteRotation

absoluteScale

A helper signal for operating on the scale in world space.

Retrieving the scale using this signal returns the scale in world space. Similarly, setting the scale using this signal transforms the new value to local space.

If the new value is a function, the scale of this node will be continuously updated to always match the position returned by the function.

Unlike scale, this signal is not compound - it doesn't contain separate signals for the x and y components.

Inherited from Img.absoluteScale

alignContent

Inherited from Img.alignContent

alignItems

Inherited from Img.alignItems

alignSelf

cachePadding

Controls the padding of the cached canvas used by this node.

readonly public compositeOperation: SimpleSignalGlobalCompositeOperationLatex
Inherited from Img.compositeOperation

cornerSharpness

readonly public cornerSharpness: SimpleSignalnumberLatex

Controls the sharpness of smoothCorners.

This property only affects the way rounded corners are drawn. To control the corner radius use the radius property.

end

readonly public end: SimpleSignalnumberLatex

A percentage from the start after which the curve should be clipped.

The portion of the curve that comes after the given percentage will be made invisible.

This property is usefully for animating the curve appearing on the screen. The value of 0 means the very start of the curve (accounting for the startOffset) while 1 means the very end (accounting for the endOffset).

This property lets you specify where along the defined curve the actual visible portion ends. For example, setting it to 20 will make the last 20 pixels of the curve invisible.

This property is useful for trimming the curve using a fixed distance. If you want to animate the curve appearing on the screen, use end instead.

Inherited from Img.middle

minHeight

Inherited from Img.minHeight

minWidth

Inherited from Img.minWidth

offset

readonly public offset: Vector2SignalLatex

Represents the offset of this node's origin.

By default, the origin of a node is located at its center. The origin serves as the pivot point when rotating and scaling a node, but it doesn't affect the placement of its children.

The value is relative to the size of this node. A value of 1 means as far to the right/bottom as possible. Here are a few examples of offsets:

  • [-1, -1] - top left corner
  • [1, -1] - top right corner
  • [0, 1] - bottom edge
  • [-1, 1] - bottom left corner

The value represents the radius of the quarter circle that is used to round the corners. If the value is a number, the same radius is used for all corners. Passing an array of two to four numbers will set individual radii for each corner. Individual radii correspond to different corners depending on the number of values passed:

// top-left-and-bottom-right | top-right-and-bottom-left
[10, 30]
// top-left | top-right-and-bottom-left | bottom-right
[10, 20, 30]
// top-left | top-right | bottom-right | bottom-left
[10, 20, 30, 40]

shrink

readonly public shrink: SimpleSignalnumberLatex
Inherited from Img.shrink

size

Represents the size of this node.

A size is a two-dimensional vector, where x represents the width, and y represents the height.

The value of both x and y is of type Length which is either:

  • number - the desired length in pixels
  • ${number}% - a string with the desired length in percents, for example '50%'
  • null - an automatic length

When retrieving the size, all units are converted to pixels, using the current state of the layout. For example, retrieving the width set to '50%', while the parent has a width of 200px will result in the number 100 being returned.

When the node is not part of the layout, setting its size using percents refers to the size of the entire scene.

Examples

Inherited from Img.size

skew

readonly public skew: Vector2SignalLatex

Represents the skew of this node in local space of its parent.

Examples

Inherited from Img.skew

smoothCorners

readonly public smoothCorners: SimpleSignalbooleanLatex

Inherited from Img.start

startArrow

readonly public startArrow: SimpleSignalbooleanLatex

Whether to display an arrow at the start of the visible curve.

This property lets you specify where along the defined curve the actual visible portion starts. For example, setting it to 20 will make the first 20 pixels of the curve invisible.

This property is useful for trimming the curve using a fixed distance. If you want to animate the curve appearing on the screen, use start instead.
