彩色像素线
在组件中，我必须显示几行彩色像素。线条的每个像素都被赋予一种颜色。什么样的元件适合构建线路或者什么样的元件适合容纳像素？
In a component I must display several lines of colored pixels. Each pixel of the line is given a color. What kind of component is suitable to build the line or what kind of component is suitable to hold pixels?

只需扩展
JComponent并在paintComponent()方法中绘制线条/像素即可。Just extend
JComponentand paint the lines/pixels in thepaintComponent()method.对我来说，最好的（但可能不是最简单的）方法是实现一个自定义的 Paint 类，它允许设置颜色区域 - 有点像 GradientPaint 类，但更灵活。
然后，您将在绘制线条之前调用
Graphics2D.setPaint(myPaint)。Paint实现可以提供一个带有start和end的方法setColorForRegion(double start, double end, Color color)取 0.0 到 1.0 之间的值来标记线上的区域。实现 Paint 类可能有点复杂，但好处是，您可以调整线条大小并在任何方向上绘制它们，同时保留颜色图案。
To me the best (but maybe not easiest) way would be implementing a custom
Paintclass that allows for setting colour regions - a bit like theGradientPaintclasses but more flexible.Then you would call
Graphics2D.setPaint(myPaint)just before you draw the line.The
Paintimplementation could offer a methodsetColorForRegion(double start, double end, Color color)withstartandendtaking values between 0.0 and 1.0 to mark a region on the line.Might be a bit complicated to implement the
Paintclass, but the benefit is, that you can resize the lines and draw them in any direction while preserving the color pattern.
