Hi,
Could you please try using actions
var dest = Folder(Folder.desktop);
function main() {
String.prototype.hexEncode = function () {
var hex = '';
for (var i = 0; i < this.length; i++) {
hex += '' + this.charCodeAt(i).toString(16);
}
return hex;
};
function writeFile(fileDestStr, contents) {
var newFile = File(fileDestStr);
newFile.open('w');
newFile.write(contents);
newFile.close();
};
var

That might be technically true but the issue still stands that you export JPG via scripting by default in 72 ppi but I need to export in 300, and this is an available setting within File > Export As that I can't find a scripting solution for other than what Charu shows for loading an action:
Thanks for the reply Carlos, also in the other thread.
I have already tried that method and i bump into a limit. I find this weird, because with the Export for screens dialog it does work. I think the width in that panel is the same as SCALEBYWIDTH right? see screengrab
The "issue" i have is that im making a logo packer panel, at least ive been doing upgrades to an existing one, adding more features and customizing it. The original exported the files at the original docs size, which was horrible. In my test file, the logo mark is around 27x27 pixels. When i used my script to get it to 1000px or testing it with hard-coded values, the max goes up to 500 something. When i open a doc its 500x500px that is using SCALEBYRESOLUTION. When i try to use SCALEBYWIDTH the max is around 777 or so. When i use hard-coded 1000 is throws this error again it cant export. Yet the other formats, png, ai and pdf work just fine using that same approach. Though AI and PDF use the saveas function.
This is the panel im updating. For me as a graphic design this is so handy, takes a 1-2 hour job and does it with seconds. It exports all files to there own folder with proper naming like digital, print, cmyk or rgb, also adds logo, logomark, logotype or slogan. Users can each use the current selection or drag and drop the active selection onto the panel. I also added easy open export folder and clean eport folder functions. Also added the github page and issue page so users can easily report bugs or other issues they find. 
This is how the oroginal panel looks. Hope the dev doesnt mind me adjust it a bit. Ive posted on his github, but no response yet.
I noticed the bigger formats of the logo do export. Also the SCALEBYWIDTH does exactly do what i need, i wasnt using it properly. I used a scale method calculated from the basewidth and did some math to get a scale value. I just need to hardcode say 1000px.
What i now see is that the minimal input it takes is a logo of 70pt wide. everything below that will fail. This is weird because if i use the dialog, the scale width method does work?!?
Though i need to think of a clean method to do this. I think i would need to make a function which only upscale the actual shapes/objects for the JPG version. Then after the export it deletes all of these. I do this because normally a logo i setup in a scale so it can be used easy for designing items. So i set a scale usefull for print items like business cards and letterheads. That way its easier when they are placed inside Indesign. You wont get a HUGE logo there.
I think i would need to clean those items because perhaps users would like to save this sheet with all logo versions. I need to think about it. Perhaps ill make it an options or so.
