Tool Color Look Up Table (LUT)

I needed to build this look up table so I thought I'd share it. It's based on a 'Standard list' found on the internet that seems to match up fairly closely with the colors in the designer, let me know if you find any glaring omissions.

I have added the control colors that appear in the designer, some of which duplicate standard colors (or themselves). So when looking up from an int, you may get a standard color name as opposed to the control color name you were expecting. And if you can't remember what you were expecting, that's all well and good .

The library contains 6 Methods:

SLColorLUT
Author: Steve Laming
Version: 1

• Methods:
  • GetAllNames As String()
    Returns all color names in an array - Sorted
    
    GetColorAlpha(ColorInt As int) As int
    Returns the alpha value of ColorInt
    
    GetColorInt(ColorName As String) As int
    Returns a color int from a color name
    
    GetColorName(ColorInt As int) As String
    Returns a color name from a color int
    
    GetRGB(color As int) As int()
    Returns the RGB colors in a array (r,g,b)
    
    GetRGBHex(color As int) As String
    Returns the RGB Hex string in a "#rrggbb"
    
    Initialize As String
    Initializes the Object.
    
    IsInitialized As boolean
    Tests whether the object has been initialized.
    
    Depends on:
    javaobject

The B4A Reference App builds a listview showing the color, color name, hex and int for all colors in the table. A handy reference.

It's a B4A only library.

Copy the jar and xml files to your addl libs folder.

I hope you find it useful.

V1.01 attached
Added Reference App.

New version compiled for B4a 3 Beta3. Please download this version if you are using B4a V3 beta 3 or later.

Thanx for sharing this.

I get an error while compiling the Example: "A referenced library is missing: slarrays"

 

[stevel05]

Ah OK, just deselect it in the libs pane, it's not needed. I'll upload a new version. I must have been click happy

 

[DonManfred]

I dont have this Library and therefor i cannot deselect it in the Libs-pane.

There are only two libs marked in the b4a-file:
NumberOfLibraries=2
Library1=core
Library2=slcolorlut

And the second, i think, is needed for the example, right? There is no slarreys referenced. I think it must be a reference from your library.

In your Lib-XML stands:
<dependsOn>slarrays</dependsOn>

Can i remove that line from XML-File or should i wait for a new upload?

 

[stevel05]

Of course, try downloading it again now.

I think I had it selected when I compiled the library. Something to watch out for.

 

[DonManfred]

Did dowload again and example now compiles without error.

Thanx

BTW: Nice lib. Again thanx for sharing it!

You're welcome

Update to V1.01 adds three methods:

getRGB, getRGBHex and GetColorAlpha

getRGB returns the RGB values as an array.

getRGBHex returns the RGB values as a hex string in the form #rrggbb

getColorAlpha returns the alpha content of the color.

 

[stevel05]

Added B4A reference app which shows color, color name, hex and int values for all the colors in the table.
