All images made on Windows have size 0

I use this snippets

        return jimp.read(srcFileName)
            .then( img => {
                img
                .resize(width, jimp.AUTO)
                .quality(75)                 // set JPEG quality
                .write(destFileName);

                returnObj.fname = destFileName;
                console.log("Created new image:", srcFileName);

                return resolve(returnObj);
            })
            .catch (err => reject(err) );

the files are being created but have size 0 bytes in Win 10. All working on Ubuntu though. What could be wrong?

Can’t reproduce on Windows 7 using the following test script:

var Jimp = require("jimp");

Jimp.read("lenna.png").then( img => {
    img
    .resize(100, Jimp.AUTO)
    .quality(75)
    .write("lenna-100px.png");
})
.catch (err => reject(err) );

Does it still present on Windows 10?

I found an interesting situation. If I use image.write(“filename.jpg”) from within an async function which is called from a Promise, then it doesn’t complete until the top-level Promise is completed, even if I use await.

The fix is to use the Async version every time it is being called from within any async process: image.writeAsync(“filename.jpg”); I think I’ll probably only use writeAsync going forward. The other one was creating strange problems, when used within async and Promises.
