我试图逐渐将单元格的背景颜色更改为黑色,我发现Range.Interior.Color方法返回一个看似随意的Long。查看MSDN上的文档,几乎没有关于此数字代表什么的信息。有没有办法从这个长度返回RGB值。我实际上需要RGB(红色,绿色,蓝色)功能的反面。
答案 0 :(得分:38)
“任意”数字是RGB值(B * 256 ^ 2 + G * 256 + R)的数学组合和十六进制颜色值到十进制数(基数16到基数10)的转换,具体取决于你想以哪种方式看待它。只是不同的基础。下面是我在为Excel编写的XLAM addin文件中使用的方法。这种方法已经多次派上用场了。我已将文档包含在我的addin文件中。

简答:
此功能没有内置功能。你必须编写自己的函数。
长答案:
从Interior.Color属性返回的long是我们习惯在html中查看颜色的典型十六进制数的十进制转换,例如“66FF66”。此外,常量xlNone(-4142)可以传递给设置单元格,在背景中没有颜色,但是这些单元格从RGB(255, 255, 255)
属性标记为白色Get
。知道了这一点,我们就可以编写一个返回一个或所有相应RGB值的函数。

R = C Mod 256
G = C \ 256 Mod 256
B = C \ 65536 Mod 256
比使用左右中间的六角形str快几倍 一些人建议
答案 3 :(得分:2)
另一个答案对我不起作用。我发现:
R = C And 255
G = C \ 256 And 255
B = C \ 256 ^ 2 And 255
它运作正常。

Mark Balhoff的VBA脚本运行正常。所有的功劳归他所有。
如果您还想获取条件格式的单元格的颜色代码/索引,则可以这样修改代码:

应该注意,对于十六进制值,如果要导出到HTML,也会有一些古怪之处。
理想情况下,您将根据各个颜色创建一个十六进制字符串,而不是从ColorVal数字返回一个十六进制。
原因是,如果单元格是“纯”颜色(如绿色/蓝色),则可能会得到无效的十六进制数字
红色-RGB(255,0,0)返回'FF'-应该返回'FF0000'
蓝色-RGB(0,0,255)返回'FF00000'-应该返回'0000FF'
如果使用它们创建HTML / CSS颜色输出,则任何蓝色单元格都将变成红色。
我修改了脚本,以基于RGB值来组装每两个字符的十六进制“块”,而UDF仅填充了前导0并返回了一个字符的输出(希望如果您正在阅读,可以做出类似的东西)
Color = ZeroPad(Hex((colorVal Mod 256)), 2) & ZeroPad(Hex(((colorVal \ 256) Mod 256)), 2) & ZeroPad(Hex((colorVal \ 65536)), 2)
-编辑:忘记包含UDF的代码...
Function ZeroPad(text As String, Cnt As Integer) As String
'Text is the string to pad
'Cnt is the length to pad to, for example ZeroPad(12,3) would return a string '012' , Zeropad(12,8) would return '00000012' etc..
Dim StrLen As Integer, StrtString As String, Padded As String, LP As Integer
StrLen = Len(Trim(text))
If StrLen < Cnt Then
For LP = 1 To Cnt - StrLen
Padded = Padded & "0"
Next LP
End If
ZeroPad = Padded & Trim(text)
ENDOF:
End Function
顺便说一句-如果您希望在表单编辑器中显示十六进制代码(除了普通的HTML十六进制颜色外,它具有自己的标准)

Color = "&H00" & ZeroPad(Hex((colorVal \ 65536)), 2) & ZeroPad(Hex(((colorVal \ 256) Mod 256)), 2) & ZeroPad(Hex((colorVal Mod 256)), 2) & "&"
