get swatches in dropdown list with color preview...

[dhishok]

Hi experts,

I am creating one gui for swatches related automation task in CS4 using javascript. Is it possible to get swatches in dropdown list with its color preview? Same like colors in Swatches palette.

Your help will be much appreciated. Thanks in advance.

Hi @Marc Autret,

This code is not working, can you fix this?

[brian_p_dts]

Sumit, code was broken when forums were transferred. Look through the code for missing iterators in for loops. For instance I saw that colors.name should be colors[n].name

[SumitKumar]

Hi @brian_p_dts,

Thank you for your response.

Yes code are broken and I have fixed at 4 places.

Regards,

[Mathias Moehl]

Could you please share the fixed solution? I would be very interested, too 🙂

Hi  Mathias,

see Marc's original code at his own website:

Amazing, thank you!

This does not work for me. I tried several times. But couldn't work on CC 2019 windows.

Here is an improved version of my original draft.

This one should support most of the Swatch types including Spot colors (Mixed Inks and Gradients remain in the todo list).

Also, it offers a localisation feature for special color names (None, Paper, Black, Registration).

Marc, this is an awesome find. If you can find Javascript implementations of Freetype and zlib, you can even add font previews to dialogs!

Some more fun, using 3 different images -- for CMYK, RGB, and "other":

Now I think I could make that Space Invaders script I was dreamin' about ...

[_Jongware_-9BC6tI]

.. Here is a slightly easier to change PNG class. It adds one parameter to pngSwatch: the size of the new image.

Hi Jongware, Harbs & Tomaxii

Thanks to everyone who are all supported for this task.

Great support.

Hi Jongware,

How is it possible? two icons in DropDownList?

Did you join two png strings?

Hi @SumitKumar 
in CC 2022 and CC2023 does not work
Mistake -
ColorSpace is not defined.
n = swatches.length,
Well dry element

[JeamCJ]

Hi @SumitKumar 

Do you know how I can change the size, that is, instead of 13 x 13 it should be 50 x 50 px, thanks

[Colin Flashman]

Love the way this works. Please excuse my ignorance, but if I want to apply the value selected from the dropdown field to a task at hand (e.g. changing the color of a QR code), how do I call this value in?

A typical QR code line looks like this:

myPageItem.createHyperlinkQRCode("http://www.adobe.com", "Magenta");

I've swapped out the web address for a variable I'm calling in, but I can't seem to get the syntax right to replace the color:

myPageItem.createHyperlinkQRCode(myURL, ddl.selection);

Can anyone please let me know where my syntax is going wrong? Thank you.

[Kasyan Servetsky]

Hi Colin,

Recently I wrote a script using this feature.

It’s not as simple as it seems at the start: some swatches may produce an error. For example, this one:

On this line

color.space = RGB; 

it produces an error: Cannot edit this color property.

 To work around this issue, I enclosed Marc’s function into a try-catch block and my function which returns either the colors array if everything is ok, or null.

function GetColors() {
	try { 
// Marc's code here
	}
	catch(err) {
		$.writeln(err.message + ", line: " + err.line);
		colors = null;
	}
 
	return colors;
}

Then in the dialog box, in an error occurred (colors == null), the swatches are not displayed: only their names instead. Otherwise, they are processed like so:

w.g1.pl.ddl = w.g1.pl.add("dropdownlist", undefined, ((colors == null) ? allSwatchNames : undefined));
if (colors != null) {
	var n = colors.length;
	for (i = 0 ; i < n ; ++i) {
		 (w.g1.pl.ddl.add("item", "\xa0"+colors[i].name)).image = colors[i].png; 
	}
}
w.g1.pl.ddl.selection = set.oddSwatchColor[0];

In the beginning, I get the array of swatches like this:

for (var s = 0; s < doc.swatches.length; s++) {
	allSwatches.push(doc.swatches[s]);
	allSwatchNames.push(doc.swatches[s].name);
}

And apply the selected swatch to a paragraph like so:

par.paragraphShadingColor = allSwatches[set.oddSwatchColor[0]];

where set.oddSwatchColor[0] is drop down list's selection.index.

Hope it helps!

If it's not clear, let me know and I'll share the whole script.
