color sampler in the foreground

[Geppetto Luis]

I would like the color selected by color sample

be put in the foreground window.

// 2017, use it at your own risk;

#target photoshop

if (app.documents.length > 0) {

var myDocument = app.activeDocument;

app.foregroundColor = myDocument.colorSamplers[0].color

};

It works perfectly

because you wrote it use it at your own risk?

sorry if you take advantage of your help

and if I wanted to pick the color of a selection

be put in the foreground window.

I just like to make sure that I make no guarantees about Scripts I post.

What do you mean exactly? A Selection may cover any number of pixels of different colors, do you mean the average?

Maybe posting a screenshot or mock-up might help me understand what you are trying to achieve.

A selection can cover any number of pixels of different colors, do you mean the average?

I meant the average.

You have to test whether this gives you the intended results:

// set foregtound color to selection average;

// 2017, use it at your own risk;

#target photoshop

if (app.documents.length > 0) {

var myDocument = app.activeDocument;

if (myDocument.mode == DocumentMode.RGB) {

var theR = histogramMean (myDocument.channels[0].histogram);

var theG = histogramMean (myDocument.channels[1].histogram);

var theB = histogramMean (myDocument.channels[2].histogram);

// make forground color;

var theColor = new SolidColor();

theColor.rgb.red = theR;

theColor.rgb.green = theG;

theColor.rgb.blue = theB;

app.foregroundColor = theColor;

};

};

//////

function histogramMean (histo) {

var mean = 0;

var total = 0;

for (var n = 0; n < histo.length; n++) {

total = total + histo;

};

for (var m = 0; m < histo.length; m++) {

var thisValue = histo;

mean = mean + (m * thisValue / total);

};

return mean

};

Perfect

The code would only work for RGB images, if you need to precess others (CMYK, Grayscale …) you need to adapt it accordingly.

thanks for your time.
