What is MIME type "image/vicar"?

A MIME type is a string that tells browsers and other tools how to handle a particular kind of file.

The image/vicar MIME type indicates a file in the VICAR format. This format was developed for storing and transmitting complex image data, especially from space missions. It is named after Video Image Communication And Retrieval and is designed to preserve detailed metadata alongside image data.

Programs use the image/vicar MIME type to identify files that might contain multiple image channels, scientific measurements, or imaging parameters. This helps software correctly process and display the image.

Files such as IMG, VIC, and VICAR use this MIME type.

This format is key in scientific environments where detailed information about the image is critical.

FAQ

What is a MIME type?

A MIME (Multipurpose Internet Mail Extensions) type is a standard that indicates the nature and format of a document, file, or assortment of bytes. MIME types are defined and standardized in IETF's RFC 6838.

MIME types are important because they help browsers and servers understand how to process a file. When a browser receives a file from a server, it uses the MIME type to determine how to display or handle the content, whether it's an image to display, a PDF to open in a viewer, or a video to play.

MIME types consist of a type and a subtype, separated by a slash (e.g., text/html, image/jpeg, application/pdf). Some MIME types also include optional parameters.

How do I find the MIME type for a file?

You can check the file extension or use a file identification tool such as file --mime-type on the command line. Many programming languages also provide libraries to detect MIME types.

Why are multiple MIME types listed for one extension?

Different applications and historical conventions may use alternative MIME identifiers for the same kind of file. Showing them all helps ensure compatibility across systems.
