Constructor
new LinearGradient(colorStops, direction?)
Parameter | Type | Description |
---|---|---|
colorStops | Array<Color | [Color, Percent]> |
An array with at least one color stop. Defines the position and the offset of the gradient color stop. |
direction | number |
The direction of the gradient line in degrees. Optional. |
Methods
equals(value)
Tests if the given value is a LinearGradient
instance that is deeply equal to this one.
Parameter | Type | Description |
---|---|---|
value | LinearGradient |
Returns: boolean
toString()
Returns a CSS string representation of the linear gradient.
Returns: string
Static Methods
from(linearGradientValue)
Creates a new instance of LinearGradient using any valid linear gradient expression. For any other value, including null
and 'initial'
the method throws.
Parameter | Type | Description |
---|---|---|
linearGradientValue | LinearGradientValue |
The value to create a LinearGradient instance from |
Returns: LinearGradient
isLinearGradientValue(value)
Returns true if value is a LinearGradientValue. This includes null
and 'initial'
. Use this to check if a value will be accepted by a linear gradient property. This is also a valid TypeScript type guard function.
Parameter | Type | Description |
---|---|---|
value | any |
The value to test |
Returns: boolean
isValidLinearGradientValue(value)
Returns true if value is a valid LinearGradientValue. This excludes null
and 'initial'
. Use this to check if a value will be accepted by LinearGradient.from. This is also a valid TypeScript type guard function.
Parameter | Type | Description |
---|---|---|
value | any |
The value to test |
Returns: boolean
