How to write raw binary file with NumPy array data?

The numpy documentation states “Information on endianness and precision is lost”. tofile only writes the raw binary data of the array, not the metadata of the array. A typical use case is to open a file, write a header appropriate for the file type, and use tofile to fill in the raw data.

What do you mean by RAW file format?

A “raw” file that is intended to be used with a camera-image processing program like Raw Studio and Irfraview is not a raw-binary dump of the image-data with no header. Instead the “raw” moniker refers to the fact that the image has a minimal amount of image-processing applied in-camera.
