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
