This tutorial explains how to enable the PHP Exif extension, read a JPEG's Exif data, and extract the MeteringMode value to identify the camera's metering mode, providing complete code examples and a brief interpretation of common metering mode values.
This tutorial demonstrates how to install the exifread library, read an image's binary data in Python, extract GPS coordinates and other EXIF metadata, and print the results, while also noting image compression effects and possible extensions such as reverse‑geocoding.
This article demonstrates how to use the Java metadata‑extractor library to read EXIF GPS information from photos, convert the coordinates to a human‑readable address via Baidu's reverse‑geocoding API, and provides a complete runnable example with Maven dependency and utility code.
This article explains how to detect the EXIF Orientation tag on mobile‑captured photos, rotate them correctly with canvas, and compress the result to reduce size, providing a lightweight solution for fixing 90° rotation issues on iPhone and certain Android devices.
