vipsheader(1) General Commands Manual vipsheader(1)
NAME
vipsheader - prints information about an image file
SYNOPSIS
vipsheader [OPTIONS ...] files ...
DESCRIPTION
vipsheader(1) prints image header fields to stdout.
OPTIONS
-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 printed.
-f FIELD, --field=FIELD
Print the value of FIELD from the 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).
You can use multiple "-f" arguments to print the values of many
fields.
EXAMPLES
$ vipsheader -f width ~/pics/*.v
