.SH SYNOPSIS
|
|
vipsheader [OPTIONS ...] files ...
|
|
.SH DESCRIPTION
|
|

|
|
prints image header fields to stdout.
|
|
|
|
.SH OPTIONS
|
|
|
|
.TP
|
|
.B -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.
|
|
|
|
.TP
|
|
.B -f FIELD, --field=FIELD
|
|
Print value of
|
|
.B 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
|
|
.B getext
|
|
prints the VIPS extension block: the XML defining the image metadata. You can
|
|
alter this, then reattach with
|
|
.B vipsedit(1).
