I can't create a Photoshop Script that saves a High Quality Gif :(

I'm struggling for a long time trying to make a Photoshop Script that needs to save my GIF with the best settings. I've a preset I use that save my GIFs with the best quality I can get. These are the settings I'm using for high quality:

But, when I'm trying to run my script, even if I set the same settings it doens't save my gif as the same quality as my preset.

Like in these two images:

Saving with the preset in Photoshop

Saving with the script

This is my script:

#target photoshop
app.bringToFront();

var doc = activeDocument;

function saveGIF (fileName){
        
        var myFile = new File(doc.path + "/" + fileName + ".gif")
                
        var gifOptions = new ExportOptionsSaveForWeb(); 
        
        gifOptions.format = SaveDocumentType.COMPUSERVEGIF; 
        gifOptions.ColorReductionType = ColorReductionType.SELECTIVE;
        gifOptions.dither = Dither.DIFFUSION;
        gifOptions.ditherAmout = 100;
        gifOptions.colors = 256;
        gifOptions.interlaced = true;
        gifOptions.transparency = true;
        gifOptions.transparencyAmount = 100;
        gifOptions.transparencyDither = Dither.NONE;
        gifOptions.webSnap = 0;
        gifOptions.quality = 100;
        gifOptions.lossy = 0;       
                
        doc.exportDocument(myFile, ExportType.SAVEFORWEB, gifOptions);
    
}


var fileName = doc.name.replace(/.\w+$/,"");

saveGIF(fileName);

Does someone knows what am I doing wrong? Or how can I solve this problem?

Thanks! 🙂

Thanks!

Looks like I could solve by using the "GIFSaveOptions" instead of using the "ExportOptionsSaveForWeb" method.

I hope it will work in all files, I've made a few tests here and it worked.

The way it worked is like this:

#target photoshop
app.bringToFront();

var doc = activeDocument;

function saveGIF (fileName){
        
        var myFile = new File(doc.path + "/" + fileName + ".gif")
                
        var gifOptions = new GIFSaveOptions(); 
        
        gifOptions.palette = Palette.LOCALSELECTIVE;
        gifOptions.colors = 256;
        gifOptions.dither = Dither.DIFFUSION;
        gifOptions.ditherAmout = 100;
        gifOptions.forced = ForcedColors.WEB;
        gifOptions.interlaced = true;
        gifOptions.matte = MatteType.WHITE;
        gifOptions.preserveExactColors = true;
        gifOptions.transparency = true;       
        
        doc.saveAs(myFile, gifOptions, true);
    
};

var fileName = doc.name.replace(/.\w+$/,"");

saveGIF(fileName);

Proofreading is important. Your script has both logic and spelling errors in it, fix those first.

Have you tried generating you code with scriptListener to get Action Manager code?

var fileName = "/" + doc.name.replace(/.\w+$/,"") + ".gif";

saveGIF(fileName);

But it didn't work as expected. It didn't save my image. 😞

And to be honest, I'm really bad into handling action manager code.

I'm just trying to create this script that save my image as a high quality gif in the same folder as the .psd file and with the same name as the original file.
