How to detect the image resolution (dpi)?

[brunolemos]

Is there a way to take an image uploaded by the user and get their dpi value in client side (without any server call)?

There isn't an exported function but i can be easily added.
Instead of setting the bytes we should return the values from them.
This would work only for PNG and JPEG/JFIF not exif and i m not sure for WEB/P
