本文整理了Java中org.eclipse.swt.graphics.RGB类的一些代码示例，展示了RGB类的具体用法。这些代码示例主要来源于Github/Stackoverflow/Maven等平台，是从一些精选项目中提取出来的代码，具有较强的参考意义，能在一定程度帮忙到你。RGB类的具体详情如下：
包路径：org.eclipse.swt.graphics.RGB
类名称：RGB

RGB介绍

[英]Instances of this class are descriptions of colors in terms of the primary additive color model (red, green and blue). A color may be described in terms of the relative intensities of these three primary colors. The brightness of each color is specified by a value in the range 0 to 255, where 0 indicates no color (blackness) and 255 indicates maximum intensity.

The hashCode() method in this class uses the values of the public fields to compute the hash value. When storing instances of the class in hashed collections, do not modify these fields after the object has been inserted.

Application code does not need to explicitly release the resources managed by each instance when those instances are no longer required, and thus no dispose() method is provided.
[中]此类的实例是根据主添加颜色模型（红色、绿色和蓝色）对颜色的描述。颜色可以用这三种原色的相对强度来描述。每种颜色的亮度由0到255之间的值指定，其中0表示无颜色（黑色），255表示最大强度。
此类中的hashCode（）方法使用公共字段的值来计算哈希值。在散列集合中存储类的实例时，不要在插入对象后修改这些字段。
当不再需要每个实例时，应用程序代码不需要显式释放这些实例管理的资源，因此不提供dispose()方法。
