        - `color` GoogleTypeColor — Represents a color in the RGBA color space. This representation is designed for simplicity of conversion to and 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 have information about the absolute color space that should be used to interpret the RGB value—for example, sRGB, Adobe RGB, DCI-P3, and BT.2020. 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; Color.Builder resultBuilder = Color .newBuilder() .setRed(red / denominator) .setGreen(green / denominator) .setBlue(blue / denominator); int alpha = color.getAlpha(); if (alpha != 255) { result.setAlpha( FloatValue .newBuilder() .setValue(((float) alpha) / denominator) .build()); } return resultBuilder.build(); } // ... Example (iOS / Obj-C): // ... static UIColor* fromProto(Color* protocolor) { float red = [protocolor red]; float green = [protocolor green]; float blue = [protocolor blue]; FloatValue* alpha_wrapper = [protocolor alpha]; float alpha = 1.0; if (alpha_wrapper != nil) { alpha = [alpha_wrapper value]; } return [UIColor colorWithRed:red green:green blue:blue alpha:alpha]; } static Color* toProto(UIColor* color) { CGFloat red, green, blue, alpha; if (![color getRed:&red green:&green blue:&blue alpha:&alpha]) { return nil; } Color* result = [[Color alloc] init]; [result setRed:red]; [result setGreen:green]; [result setBlue:blue]; if (alpha <= 0.9999) { [result setAlpha:floatWrapperWithValue(alpha)]; } [result autorelease]; return result; } // ... Example (JavaScript): // ... var protoToCssColor = function(rgb_color) { var redFrac = rgb_color.red || 0.0; var greenFrac = rgb_color.green || 0.0; var blueFrac = rgb_color.blue || 0.0; var red = Math.floor(redFrac * 255); var green = Math.floor(greenFrac * 255); var blue = Math.floor(blueFrac * 255); if (!('alpha' in rgb_color)) { return rgbToCssColor(red, green, blue); } var alphaFrac = rgb_color.alpha.value || 0.0; var rgbParams = [red, green, blue].join(','); return ['rgba(', rgbParams, ',', alphaFrac, ')'].join(''); }; var rgbToCssColor = function(red, green, blue) { var rgbNumber = new Number((red << 16) | (green << 8) | blue); var hexString = rgbNumber.toString(16); var missingZeros = 6 - hexString.length; var resultBuilder = ['#']; for (var i = 0; i < missingZeros; i++) { resultBuilder.push('0'); } resultBuilder.push(hexString); return resultBuilder.join(''); }; // ...
          - `green` number, float — The amount of green in the color as a value in the interval [0, 1].
          - `blue` number, float — The amount of blue in the color as a value in the interval [0, 1].
          - `alpha` number, float — The fraction of this color that should be applied to the pixel. That is, the final pixel color is defined by the equation: `pixel color = alpha * (this color) + (1.0 - alpha) * (background color)` This means that a value of 1.0 corresponds to a solid color, whereas a value of 0.0 corresponds to a completely transparent color. This uses a wrapper message rather than a simple float scalar so that it is possible to distinguish between a default value and the value being unset. If omitted, this color object is rendered as a solid color (as if the alpha value had been explicitly given a value of 1.0).
          - `red` number, float — The amount of red in the color as a value in the interval [0, 1].

            - `addressValue` GoogleTypePostalAddress — Represents a postal address, such as for postal delivery or payments addresses. With a postal address, a postal service can deliver items to a premise, P.O. box, or similar. A postal address is not intended to model geographical locations like roads, towns, or mountains. In typical usage, an address would be created by user input or from importing existing data, depending on the type of process. Advice on address input or editing: - Use an internationalization-ready address widget such as https://github.com/google/libaddressinput. - Users should not be presented with UI elements for input or editing of fields outside countries where that field is used.

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, month, or day are 0, the DateTime is considered not to have a specific year, month, or day respectively. 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_offset` oneof is set. Consider using `Timestamp` message 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.

          - `dateValue` GoogleTypeDate — 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, with a zero year (for example, an anniversary). * A year on its own, with a zero month and a zero day. * A year and month, with a zero day (for example, a credit card expiration date). Related types: * google.type.TimeOfDay * google.type.DateTime * google.protobuf.Timestamp

          - `addressValue` GoogleTypePostalAddress — Represents a postal address, such as for postal delivery or payments addresses. With a postal address, a postal service can deliver items to a premise, P.O. box, or similar. A postal address is not intended to model geographical locations like roads, towns, or mountains. In typical usage, an address would be created by user input or from importing existing data, depending on the type of process. Advice on address input or editing: - Use an internationalization-ready address widget such as https://github.com/google/libaddressinput. - Users should not be presented with UI elements for input or editing of fields outside countries where that field is used. For more guidance on how to use this schema, see: https://support.google.com/business/answer/6397478.
            - `recipients` string[] — Optional. The recipient at the address. This field may, under certain circumstances, contain multiline information. For example, it might contain "care of" information.
            - `locality` string — Optional. Generally refers to the city or town portion of the address. Examples: US city, IT comune, UK post town. In regions of the world where localities are not well defined or do not fit into this structure well, leave `locality` empty and use `address_lines`.
            - `sublocality` string — Optional. Sublocality of the address. For example, this can be a neighborhood, borough, or district.
            - `addressLines` string[] — Unstructured address lines describing the lower levels of an address. Because values in `address_lines` do not have type information and may sometimes contain multiple values in a single field (for example, "Austin, TX"), it is important that the line order is clear. The order of address lines should be "envelope order" for the country or region of the address. In places where this can vary (for example, Japan), `address_language` is used to make it explicit (for example, "ja" for large-to-small ordering and "ja-Latn" or "en" for small-to-large). In this way, the most specific line of an address can be selected based on the language. The minimum permitted structural representation of an address consists of a `region_code` with all remaining information placed in the `address_lines`. It would be possible to format such an address very approximately without geocoding, but no semantic reasoning could be made about any of the address components until it was at least partially resolved. Creating an address only containing a `region_code` and `address_lines` and then geocoding is the recommended way to handle completely unstructured addresses (as opposed to guessing which parts of the address should be localities or administrative areas).
            - `sortingCode` string — Optional. Additional, country-specific, sorting code. This is not used in most regions. Where it is used, the value is either a string like "CEDEX", optionally followed by a number (for example, "CEDEX 7"), or just a number alone, representing the "sector code" (Jamaica), "delivery area indicator" (Malawi) or "post office indicator" (Côte d'Ivoire).
            - `regionCode` string — Required. CLDR region code of the country/region of the address. This is never inferred and it is up to the user to ensure the value is correct. See https://cldr.unicode.org/ and https://www.unicode.org/cldr/charts/30/supplemental/territory_information.html for details. Example: "CH" for Switzerland.
            - `administrativeArea` string — Optional. Highest administrative subdivision which is used for postal addresses of a country or region. For example, this can be a state, a province, an oblast, or a prefecture. For Spain, this is the province and not the autonomous community (for example, "Barcelona" and not "Catalonia"). Many countries don't use an administrative area in postal addresses. For example, in Switzerland, this should be left unpopulated.
            - `languageCode` string — Optional. BCP-47 language code of the contents of this address (if known). This is often the UI language of the input form or is expected to match one of the languages used in the address' country/region, or their transliterated equivalents. This can affect formatting in certain countries, but is not critical to the correctness of the data and will never affect any validation or other non-formatting related operations. If this value is not known, it should be omitted (rather than specifying a possibly incorrect default). Examples: "zh-Hant", "ja", "ja-Latn", "en".
            - `postalCode` string — Optional. Postal code of the address. Not all countries use or require postal codes to be present, but where they are used, they may trigger additional validation with other parts of the address (for example, state or zip code validation in the United States).
            - `organization` string — Optional. The name of the organization at the address.
            - `revision` integer — The schema revision of the `PostalAddress`. This must be set to 0, which is the latest revision. All new revisions **must** be backward compatible with old revisions.
          - `booleanValue` boolean — Boolean value. Can be used for entities with binary values, or for checkboxes.
          - `floatValue` number, float — Float value.
          - `datetimeValue` GoogleTypeDateTime — 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, month, or day are 0, the DateTime is considered not to have a specific year, month, or day respectively. 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_offset` oneof is set. Consider using `Timestamp` message for physical time instead. If your use case also would like to store the user's timezone, that can be done in another field.

            - `year` integer — Optional. Year of date. Must be from 1 to 9999, or 0 if specifying a datetime without a year.
            - `seconds` integer — Optional. Seconds of minutes of the time. Must normally be from 0 to 59, defaults to 0. An API may allow the value 60 if it allows leap-seconds.

            - `month` integer — Optional. Month of year. Must be from 1 to 12, or 0 if specifying a datetime without a month.
            - `utcOffset` string, google-duration — UTC offset. Must be whole seconds, between -18 hours and +18 hours. For example, a UTC offset of -4:00 would be represented as { seconds: -14400 }.
            - `day` integer — Optional. Day of month. Must be from 1 to 31 and valid for the year and month, or 0 if specifying a datetime without a day.
          - `text` string — Optional. An optional field to store a normalized string. For some entity types, one of respective `structured_value` fields may also be populated.
