vipsheader1

Usage

Overview

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
