Color
Represents a color in the RGBA color space. This representation is designed
for simplicity of conversion to/from color representations in various
languages over compactness. For example, the fields of this representation
can be trivially provided to the constructor of java.awt.Color in Java; it
can also be trivially provided to UIColor's +colorWithRed:green:blue:alpha
method in iOS; and, with just a little work, it can be easily formatted into
a CSS rgba() string in JavaScript.
This reference page doesn't carry information about the absolute color
space
that should be used to interpret the RGB value (e.g. sRGB, Adobe RGB,
DCI-P3, BT.2020, etc.). By default, applications should assume the sRGB color
space.
When color equality needs to be decided, implementations, unless
documented otherwise, treat two colors as equal if all their red,
green, blue, and alpha values each differ by at most 1e-5.
Example (Java):
import com.google.type.Color;
// ...
public static java.awt.Color fromProto(Color protocolor) {
float alpha = protocolor.hasAlpha()
? protocolor.getAlpha().getValue()
: 1.0;
return new java.awt.Color(
protocolor.getRed(),
protocolor.getGreen(),
protocolor.getBlue(),
alpha);
}
public static Color toProto(java.awt.Color color) {
float red = (float) color.getRed();
float green = (float) color.getGreen();
float blue = (float) color.getBlue();
float denominator = 255.0;

if (alpha != 255) {
result.setAlpha(
FloatValue
.newBuilder()
.setValue(((float) alpha) / denominator)
.build());
}
return resultBuilder.build();
}
// ...
Example (iOS / Obj-C):
// ...

Date
Represents a whole or partial calendar date, such as a birthday. The time of day and time zone are either specified elsewhere or are insignificant. The date is relative to the Gregorian Calendar. This can represent one of the following:
- A full date, with non-zero year, month, and day values
- A month and day value, with a zero year, such as an anniversary
- A year on its own, with zero month and day values
- A year and month value, with a zero day, such as a credit card expiration

DateTime
Represents civil time (or occasionally physical time). This type can represent a civil time in one of a few possible ways:
- When utc_offset is set and time_zone is unset: a civil time on a calendar day with a particular offset from UTC.
- When time_zone is set and utc_offset is unset: a civil time on a calendar day in a particular time zone.
- When neither time_zone nor utc_offset is set: a civil time on a calendar
day in local time.
The date is relative to the Proleptic Gregorian Calendar.
If year is 0, the DateTime is considered not to have a specific year. month
and day must have valid, non-zero values.
This type may also be used to represent a physical time if all the date and
time fields are set and either case of the
time_offsetoneof is set. Consider usingTimestampmessage for physical time instead. If your use case also would like to store the user's timezone, that can be done in another field. This type is more flexible than some applications may want. Make sure to document and validate your application's limitations.

PhoneNumber
An object representing a phone number, suitable as an API wire format. This representation:
- should not be used for locale-specific formatting of a phone number, such as "+1 (650) 253-0000 ext. 123"

To do something meaningful with this number, such as format it for various
use-cases, convert it to an
i18n.phonenumbers.PhoneNumberobject first. For instance, in Java this would be: com.google.type.PhoneNumber wireProto = com.google.type.PhoneNumber.newBuilder().build(); com.google.i18n.phonenumbers.Phonenumber.PhoneNumber phoneNumber = PhoneNumberUtil.getInstance().parse(wireProto.getE164Number(), "ZZ"); if (!wireProto.getExtension().isEmpty()) { phoneNumber.setExtension(wireProto.getExtension()); } Reference(s):

An object representing a short code, which is a phone number that is typically much shorter than regular phone numbers and can be used to address messages in MMS and SMS systems, as well as for abbreviated dialing (e.g. "Text 611 to see how many minutes you have remaining on your plan."). Short codes are restricted to a region and are not internationally dialable, which means the same short code can exist in different regions, with different usage and pricing, even if those regions share the same country calling code (e.g. US and CA).

Quaternion
A quaternion is defined as the quotient of two directed lines in a
three-dimensional space or equivalently as the quotient of two Euclidean
vectors (https://en.wikipedia.org/wiki/Quaternion).
Quaternions are often used in calculations involving three-dimensional
rotations (https://en.wikipedia.org/wiki/Quaternions_and_spatial_rotation),
as they provide greater mathematical robustness by avoiding the gimbal lock
problems that can be encountered when using Euler angles
(https://en.wikipedia.org/wiki/Gimbal_lock).
Quaternions are generally represented in this form:
w + xi + yj + zk
where x, y, z, and w are real numbers, and i, j, and k are three imaginary
numbers.
Our naming choice (x, y, z, w) comes from the desire to avoid confusion for
those interested in the geometric properties of the quaternion in the 3D
Cartesian space. Other texts often use alternative names or subscripts, such
as (a, b, c, d), (1, i, j, k), or (0, 1, 2, 3), which are perhaps
better suited for mathematical interpretations.
To avoid any confusion, as well as to maintain compatibility with a large
number of software libraries, the quaternions represented using the protocol
buffer below must follow the Hamilton convention, which defines ij = k
(i.e. a right-handed algebra), and therefore:
i^2 = j^2 = k^2 = ijk = \u22121
ij = \u2212ji = k
jk = \u2212kj = i
ki = \u2212ik = j
Please DO NOT use this to represent quaternions that follow the JPL
convention, or any of the other quaternion flavors out there.
Definitions:
- Quaternion norm (or magnitude):
sqrt(x^2 + y^2 + z^2 + w^2). - Unit (or normalized) quaternion: a quaternion whose norm is 1.
- Pure quaternion: a quaternion whose scalar component (
w) is 0. - Rotation quaternion: a unit quaternion used to represent rotation.
- Orientation quaternion: a unit quaternion used to represent orientation.
A quaternion can be normalized by dividing it by its norm. The resulting
quaternion maintains the same direction, but has a norm of 1, i.e. it moves
on the unit sphere. This is generally necessary for rotation and orientation
quaternions, to avoid rounding errors:
https://en.wikipedia.org/wiki/Rotation_formalisms_in_three_dimensions
Note that
(x, y, z, w)and(-x, -y, -z, -w)represent the same rotation, but normalization would be even more useful, e.g. for comparison purposes, if it would produce a unique representation. It is thus recommended thatwbe kept positive, which can be achieved by changing all the signs whenwis negative.
