imggetfdata

imggetfdata is a software function used in image processing to retrieve comprehensive data from image files or in‑memory images. The exact implementation and naming can vary by language and library, but the function typically aims to provide both pixel data and associated metadata for downstream analysis or processing.

Inputs to imggetfdata usually include an image source, such as a file path or binary buffer, along with optional parameters that can specify color space, data type, and whether to include metadata. The function returns a structured object or record containing image dimensions (width and height), the number of channels, bit depth, and color space. It may also return a matrix or array of pixel values, a reference to a memory buffer, and, if requested, metadata blocks such as EXIF, IPTC, and XMP, plus basic statistics like histogram or min/max values.

Usage generally involves invoking the function with the chosen source and options, then accessing the resulting fields for further processing. Some implementations support synchronous operation, while others offer asynchronous or streaming interfaces to handle large images or real-time workflows.

Performance considerations include memory usage, which scales with image size and channel depth, and the need for optimized formats or chunked reads for very large images. Format support varies by library; common formats like JPEG, PNG, and TIFF are widely supported, whereas RAW, multi-page, or animated formats depend on the underlying toolkit.

,imggetfdata is part of broader image I/O and metadata tooling. It is often used in conjunction with libraries that handle encoding/decoding, color management, and feature extraction, such as OpenCV, PIL/Pillow, or libjpeg/libpng ecosystems.
