SkColor4f Reference

Color4f

Struct SkColor4f

Member

SkColor4f members may be read and written directly without using a member function.

Each component is stored as a 32-bit single precision floating point float value. All values are allowed, but only the range from zero to one is meaningful.

Each component is independent of the others; fA Alpha is not Premultiplied with fG green, fB blue, or fR red.

Values smaller than zero or larger than one are allowed. Values out of range may be used with Blend Mode so that the final component is in range.

Overview

Operator

SkColor4f operators inline class member functions with arithmetic equivalents.

Member Function

SkColor4f member functions read and modify the structure properties.

Members

operator==

Compares Color4f with other, and returns true if all components are equivalent.

Parameters

Return Value

true if Color4f equals other

Example

Example Output

colorRed == colorNamedRed

See Also

operator!=(const SkColor4f& other) const

---

operator!=

Compares Color4f with other, and returns true if all components are not equivalent.

Parameters

Return Value

true if Color4f is not equal to other

Example

Example Output

colorGray != colorNamedGray

See Also

operator==(const SkColor4f& other) const

---

vec

Returns Color4f components as a read-only array.

Return Value

components as read-only array

Example

Example Output

red=0.266667 green=0.533333 blue=0.8 alpha=0.533333
[0]=0.266667 [1]=0.533333 [2]=0.8 [3]=0.533333

---

Returns Color4f components as a writable array.

Return Value

components as writable array

Example

Example Output
