LUT browser?

[Rodrigo Gonçalves-4]

I want to test different lookup tables for my images, and I find it a bit tedious to select a different LUT every time using the menu Image-->Lookup tables. Maybe there is a more time-effective way?

I was wondering if there's something like a "LUT browser" where we can go through a list of the available LUTs using just one click or key (eg. a drop down list of available LUTs) and the LUTs is applied in real time
Alternatively, it could just be a dialog with the list of available LUTs and a 'preview' option before applying the chosen LUT.

But maybe there is already a plugin with something like a LUT manager?

Cheers,
Rodrigo

Hi,
This is not exactly a LUT manager, but the following macro creates an image
with all availble LUTs.

You might find this useful:

I rarely use the above, because I added to my StartupMacros the following
lines, so I can click on a LUT button to go forward (click) and backwards
(shift-click) in the LUTs stored in the /luts folder.
Alt-click takes you to the first LUT.
To have a preferred order,  just add a number preceeding the LUT names (i.e.
000-grey.lut, 001-fire.lut) as otherwise they will be in alphabetic order.

The mailers most likely add line breaks, so beware!

var GLlut=0;
var lutdir=getDirectory("startup")+"luts"+File.separator;
var list = getFileList(lutdir);

    if (!File.exists(lutdir) || list.length<1){
       showMessage("No LUTs in the \'\/Image\/luts\' folder.\nThe LUT Tool
will not work.");
       return;
    }
    if (isKeyDown("alt"))
     GLlut=0;
    else if (isKeyDown("shift"))
     GLlut-=1;
    else
     GLlut+=1;

    if (GLlut<0) GLlut=list.length-1;
    if (GLlut>list.length-1) GLlut=0;

    if (bitDepth()!=24)
       run("LUT... ", "open=["+lutdir+list[GLlut]+"]");

    wait(20);
    restorePreviousTool();
    showStatus(list[GLlut]);
