Set width size of exportPNG24 with scripting

I'm exporting a png 24 image but I'd like to set hte width size.  In the documentation it only specifies scale but not an actual size in example 1400.

 

      fileTypeSmart = ExportType.PNG24;
      exportOptionsSmart = new ExportOptionsPNG24();
      exportOptionsSmart.transparency = isTrue(settings.png_transparent);
app.activeDocument.exportFile(new File(imgPath.replace('.jpg', '-smartObj.png')), fileTypeSmart, exportOptionsSmart);

 

Is there away for me to add a width?

I attempting this: 

exportOptionsSmart.width = 1800;
But it does not function.

    Since it appears that it's not an option I ended up doing it by calculating the artboard width and then calculating the scale percentage for the desired image size.

    var scaleToSmart = Math.round( (templateSize / app.activeDocument.width) * 100 )

    Thank you for sharing your nice solution, OhmsG.

     

    That is exactly the same way we can get Illy (job description Adobe Illustrator) to calculate the percentage for us in a normal scaling; and she does it accurately.

     

     

     

    Without my having any scripting knowledge, with the Math.round it seems to round to an integer value of the percentage?

     

    If that is the case, I believe it must be better to use whichever non integer value gives the accurate width.

    Export for screens and Asset Export panel lets you specify a width and save a preset.

    But that is not a script

    OhmsG,

     

    Maybe far too far out, but how about something based upon the legacy Save for Web, which works in Image Size?
