- // 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, as well. Here are some examples:
- //
- // 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;
- // }
- // // ...
- //

- //
- // // ...
- //
- // 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);
