_ColorConvertValue UDF

[MrCreatoR]

Hi there,

This function was initialy created as a helper function in my other recent UDF (_GUICtrlCreateTFLabel), but after searching on the forum for such function and not finding anything like this (i was surprised actualy, i thought this kind of function could be posted long time ago), i think that i should post it here.

The colors table i got from here.

In the archive with _ColorConvertValue there is also a parser script that i used to generate the table for UDF usage.

Function Header:

; #FUNCTION# ========================================================================================
; Name...........:  _ColorConvertValue
; Description....:  Converts string color value to hex and back.
; Syntax.........:  _ColorConvertValue($sColor, $iConvertMode=-1, $aColors_Table=0)
; Parameters.....:  $sColor       - Color name or color hex value, depending on $iConvertMode.
;                    $iConvertMode  - [Optional] If this parameter <> -1, then the function will convert hex color to string value
;                                       (default is -1 - convert from string to hex).
;                    $aDefColorsTable - [Optional] If this parameter will contain an array with colors table (default is 0),
;                                       then this colors table will be used to convert the color.
;                   
; Return values..:  Success - Returns converted color value.
;                    Failure - Returns original $sColor value (if the color can not be converted).

Oh, thats pretty sweet. It doens't support ALL colors. Dont think thats necessary though.

This could be very useful!

As I saw the topic, I was wondering how this would be done. Pretty nifty!

Nicely done, and useful too.

Thanks for sharing

It's a good idea and well done, MrCreatoR, but it would be nice to be able to pass their own (arbitrary) color palette. Or make that something like _SetDefaultPalette(ByRef $aPalatte).

Thanks to all for the feedbacks.

I am not sure that i follow you. What it should do exactly? (example could help).

Dim $aDefColorsTable[140][2] = [[0xFFFFFF, 'White'],[0xFFFFF0, 'Ivory'], ...]

Func _SetColorsTable(ByRef $aColorsTable)

    ; Checks for $aColorsTable array
    
    ...

    $aDefColorsTable = $aColorsTable
    Return 1
EndFunc   ;==>_SetColorsTable

In this case _ColorConvertValue() should work with a $aDefColorsTable array.

[MrCreatoR]

; Checks for $aColorsTable array

What it should do inside the array? Switch the values?

Or you mean pass the array to use instead of the strings inside the UDF?

Your _ColorConvertValue() function works with local variables $aStrColors_Table and $aHexColors_Table. I think that would be more useful when the user can assign its value for these variables. For example, with an additional function _SetColorsTable(). In my example I used an array for simplicity. I think it is more convenient when the names of colors and their values are stored in the array. That's all.

Thank You ...
