Description

Expected Behavior

Jim.read() to read the file lenna.write('lena-small-bw.jpg') to write a file to the local folder.

Current Behavior

Jim.read() works fine. lenna.write('lena-small-bw.jpg') throws an error

Failure Information (for bugs)

index.js:139 Error: Cant access the filesystem. You can use the getBase64 method. at Jimp.write (jimp.js:33813) at index.js:132

Steps to Reproduce

the codes: Jimp.read('static/images/beach.jpg') .then(lenna => { console.log('lenna', lenna)
return lenna .resize(120, 120) // resize .quality(60) // set JPEG quality .greyscale() // set greyscale .write('lena-small-bw.jpg'); .catch(err => { console.error(err); });

Research direction
Investigate the write method implementation in jimp.js around line 33813. The error 'Cant access the filesystem' suggests the code incorrectly detects a browser environment. Check the environment detection logic and verify if the write method should allow filesystem access in Node. Look at recent commits or related issues for potential fixes. If confirmed, a fix might involve adjusting the condition to allow write in Node.
