透明度百分比和十六进制对应关系计算方法
@Test
public void rgba() throws Exception {
System.out.println("透明度 | 十六进制");
System.out.println("---- | ----");
for (double i = 1; i >= 0; i -= 0.01) {
i = Math.round(i * 100) / 100.0d;
int alpha = (int) Math.round(i * 255);
String hex = Integer.toHexString(alpha).toUpperCase();
if (hex.length() == 1) hex = "0" + hex;
int percent = (int) (i * 100);
System.out.println(String.format("%d%% | %s", percent, hex));
}
}运行结果如下所示：
