vipsheader - Man Page

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).
