For animated gifs: gifsicle sets Photoshops SaveForWeb parameter "lossy" to 60 that cannot be changed.

To batch save animated gifs I am using the great script written by SuperMerlin . Here it is:

#target photoshop; 

try{ 

var Path= activeDocument.path; 

}catch(e){var Path = "~/desktop";} 

var Name = decodeURI(app.activeDocument.name).replace(/\.[^\.]+$/, ''); 

var layerName = app.activeDocument.activeLayer.name.replace(/[:\/\\*\?\"\<\>\|]/g, "_"); 

var saveFile= new File(Path + "/" + Name + "-" + layerName + ".gif"); 

var rex = new RegExp(Name + "-" + layerName + ".gif"); 

var files = decodeURI(saveFile.fsName).replace(rex,"*.gif"); 

var cmd = 'C:/gifsicle.exe --batch --loop=forever --careful '; 

cmd += '\"' + files+ '\"'; 

SaveForWeb(saveFile); 

app.system(cmd); 

function SaveForWeb(saveFile) { 

var sfwOptions = new ExportOptionsSaveForWeb(); 

   sfwOptions.format = SaveDocumentType.COMPUSERVEGIF; 

   sfwOptions.includeProfile = false; 

   sfwOptions.interlaced = 0; 

   sfwOptions.optimized = true; 

   sfwOptions.transparency = 1; 

   sfwOptions.ColorReductionType = ColorReductionType.SELECTIVE; 

   sfwOptions.dither = Dither.NONE;   

   sfwOptions.ditherAmount = 0; 

   sfwOptions.lossy = 8;  

   sfwOptions.webSnap = 0; 

   sfwOptions.colors = 256; 

activeDocument.exportDocument(saveFile, ExportType.SAVEFORWEB, sfwOptions); 

};

And everything was great until I reinstall my computer. It looks like all photoshop and system parameters are as they were before but all my animated Gifs start to apear in a very poor quality after gifsicle. Exactly as poor as if you set in Export Option - SaveForWeb - parameter "lossy" to 60 for your animted gif.

If you open SaveForWeb - lossy is always set to 60 by default after using gifsicle. Otherwise it sets by default to whatever value was previously used.

I cannot fight that. Nothing helps so far. Would be very grateful for any help!

Are you sure that this function worked for you? I doubt her adequacy at all. It in my opinion uses unknown parameters and you just got lucky.

Try to exit Photoshop and delete the files

C: \ Users \ <USERNAME> \ AppData \ Local \ Adobe Save for Web 13.0 Prefs

And also specifically for your version of the photoshop, for example

for CS6

C: \ Users \ <USERNAME> \ AppData \ Roaming \ Adobe \ Adobe Photoshop CS6 \ Adobe Photoshop CS6 \ Recently Used Optimizations.irs

for CC2018

C: \ Users \ <USERNAME> \ AppData \ Roaming \ Adobe \ Adobe Photoshop CC 2018 \ Adobe Photoshop CC 2018 \ Recently Used Optimizations.irs

Start Photoshop, manually call Save For Web and press "Done".

Check how your script works.

In general, try to use another version of the Save For Web call

    Could you please tell me what I do wrong?

    I try to change Dither from NONE to PATTERN

    And I changed it as on the image - but it says "Error: Illegal Argument". Could you please tell how can change it?
