VIPSHEADER(1) FreeBSD General Commands Manual VIPSHEADER(1)

vipsheader - prints information about an image file

vipsheader [OPTIONS ...] files ...

vipsheader(1) prints image header fields to stdout.

-a, --all
Show all fields. Fields are displayed to be convenient for humans to read, so binary data, for example, is summarized rather than simply copied.
-f FIELD, --field=FIELD
Print value of FIELD from image header. Fields are printed in a way suitable for programs to understand, so, for example, binary data is base64-encoded and printed as a stream of characters.
The special field name getext prints the VIPS extension block: the XML defining the image metadata. You can alter this, then reattach with vipsedit(1).
