n is not defined

[wyz]

function getStringFromDB(buffer, start, length) {
        var outstr = "";
        for (var n = start; n < start+length; n++) {
            outstr += String.fromCharCode(buffer.getUint8(n));
        }
        return outstr;
    }

why in node_modules its changeTo

function getStringFromDB(buffer, start, length) {
        var outstr = "";
        for (n = start; n < start+length; n++) {
            outstr += String.fromCharCode(buffer.getUint8(n));
        }
        return outstr;
    }

and in strict mode error。。。 can fix this ???

Hi,
same issue with angular 8 only when I try to resize a picture made by screenshot with MAC OS.

packages
"exif-js": "^2.3.0",
"@digitalascetic/ngx-pica": "^8.0.1",
"blueimp-canvas-to-blob": "^3.14.0",
"pica": "^5.1.0",

code

this.subscriptions
        .add(
          this._ngxPicaService
            .resizeImages(files, 400, 300, options)
            .pipe(
              take(1)
            ).subscribe((imageResized: File) => {
              this.filePicture = imageResized;
              this.getImagePreview(imageResized);
            }, (err: NgxPicaErrorInterface) => {
              throw err.err;
            }));

Error

用这个 npm install https://github.com/exif-js/exif-js.git

For the benefit of anyone searching for the "n is not defined" message, it has been fixed but not published to npm. Some forks have been published, or you can just install directly from GitHub with the following command.

npm install https://github.com/exif-js/exif-js.git
