Bildedatafil

Bildedatafil is a generic term used in some languages (for example Swedish and German) for a file that contains image data. It refers to any digital file that stores pixel information for an image, rather than primarily descriptive text or metadata alone. The exact meaning of the term can vary by context and software.

In most cases a bildedatafil is a binary file. It may include a header that records image attributes such as width, height, color depth, and color space, followed by the pixel data. Some formats use compression, while others store uncompressed data. The internal layout depends on the specific format used.

The label bildedatafil does not specify a single format. Common image data formats include JPEG, PNG, GIF, TIFF, BMP, and RAW; these formats encode pixel values in different ways and may apply lossy or lossless compression. File identification is typically by extension or by magic numbers embedded in the file.

Metadata may accompany image data, either embedded inside the file (for example Exif, IPTC, or XMP) or stored in separate sidecar files. Some workflows separate the image data from its metadata, while others keep them together.

In software and workflows, bildedatafil is created by exporting or saving an image. It can be read by image-processing libraries and applications. In databases, image data may be stored as BLOBs, and applications may consolidate multiple images into a single data file for efficiency.

The term is context-dependent and should be understood from the surrounding documentation or usage.
