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).
