反转颜色代码 [英] Reversing a COlour Code
问题描述
我使用的是Terry Kreft的& Stephen Lebans为用户设置颜色对话框程序
为某些应用程序中的各种控件属性选择颜色。
有没有办法获取显示的颜色代码在
backcolor / forecolor / etc属性中并计算反色？用
换句话说，如果用户为控件背景选择255（红色），我希望
能够计算出该颜色的相反或负数并且
为控件的forecolor属性赋予新的颜色。
vbWhWite和其他颜色常数不是一个选项，我不认为，
因为颜色对话框允许用户混合自己的自定义颜色...
TIA可以提供任何帮助。

I use Terry Kreft''s & Stephen Lebans colour dialog procedures for users
to pick colours for various control properties in certain apps.
Is there a way to take the colour code that is displayed in a
backcolor/forecolor/etc property and calculate the "reverse colour"? In
other words, If a user picks 255 (red) for a control backcolor, I''d like
to be able to calculate the opposite or negative of that colour and
assign the control''s forecolor property the new colour.
vbWhite and other colour constants are not an option, I don''t think,
since the colour dialog allows a user to blend their own custom colour...
TIA for any help.

推荐答案
使用整数除法将颜色分解为红色，绿色和蓝色的字节
和Mod。
通过注意它们来翻转位
将它们与RGB（）函数结合使用。
假设RGB值在名为txtCombined的文本框：
Dim btRed As Byte，btGreen As Byte，btBlue As Byte
Dim lngColor as Long
btRed = Me.txtCombined Mod 256
lngColor = Me.txtCombined \ 256
btGreen = lngColor Mod 256
btRed =不是btRed
''等等

Parse the color into bytes for red, green, and blue, using integer division
and Mod.
Flip the bits by NOTing them
Combine them with the RGB() function.
Assuming the RGB value is in a text box named txtCombined:
Dim btRed As Byte, btGreen As Byte, btBlue As Byte
Dim lngColor as Long
btRed = Me.txtCombined Mod 256
lngColor = Me.txtCombined \ 256
btGreen = lngColor Mod 256
btBlue = lngColor \ 256
btRed = Not btRed
''etc.

很早就没有咖啡，我的逻辑感说：
不是ColorCode和vbWhite
应该反转任何RGB类型的颜色。
---
或
不是ColorCode和16777215如果常量vbWhite不可用？
---
[不是ColorCode ]应该反转所有位。
[和vbWhite]应该将第四个字节中的位返回到零。
Very early in the morning and without coffee my sense of logic says:
Not ColorCode And vbWhite
should reverse any RGB type color.
---
or
Not ColorCode And 16777215 if the constant vbWhite isn''t available?
---
[Not ColorCode] should reverse all the bits.
[And vbWhite] should return the bits in the fourth byte to zero.

HI Allen - 感谢你和Lyle的回复。对于子孙后代，
这里是基于你的提交的功能（Lyle'似乎有效，
但是对于我做的非常有限的测试它，我一直得到
黑色）。
我尝试将颜色解析成整数，因为RGB（）函数
需要整数参数，但我最终看到了大致不同的颜色，大部分都是黑色的。我不明白为什么使用字节
工作得更好，但是<耸肩>

HI Allen - thanks to you and Lyle for your responses. For posterity,
here''s the function I based on your submission (Lyle''s seemed to work,
but for the very limited amount of testing I did with it, I kept getting
black colours).
I tried parsing the colour into integers since the RGB() function
requires integer arguments, but I ended up with vastly different looking
colours which were mostly black. I don''t understand why using bytes
worked better, but <shrug>
Public Function fReverseColour(lngColour As Long) As Long
''Takes an RGB colour spec and reverses it.
''Thanks to Allen Browne & Lyle Fairfield''s responses on cdma
''
''Argument LngColour is the colour code fed from a colour
''property of a control''s BackColor (the usual one used
''in TCM), foreColor, etc.
Dim bytRed As Byte, bytGreen As Byte, bytBlue As Byte
Dim bytTemp As Byte
''Before using the above bytRed, etc bytes,
''use bytTemp for a calculation because for some
''lngColour codes such as the standard Access default
''form BG colour, the results of some of the division and
''mod functions is greater than 255. See error handling
Dim lngC As Long
On Error GoTo Err_Proc
bytTemp = lngColour Mod 256
bytRed = bytTemp
lngC = lngColour \ 256
bytTemp = lngC Mod 256
bytGreen = bytTemp
bytTemp = lngC \ 256
bytBlue = bytTemp
bytRed = Not bytRed
bytGreen = Not bytGreen
bytBlue = Not bytBlue
fReverseColour = RGB(bytRed, bytGreen, bytBlue)
Debug.Print "Original Colour Fed: " & lngColour & _
" Reverse: " & fReverseColour
