.\" The -*- nroff -*- definitions below are for supplemental macros used
.\" in Tcl/Tk manual entries.
.\"
.\" .AP type name in/out ?indent?
.\"	Start paragraph describing an argument to a library procedure.
.\"	type is type of argument (int, etc.), in/out is either "in", "out",
.\"	or "in/out" to describe whether procedure reads or modifies arg,
.\"	and indent is equivalent to second arg of .IP (shouldn't ever be
.\"	needed;  use .AS below instead)
.\"
.\" .AS ?type? ?name?
.\"	Give maximum sizes of arguments for setting tab stops.  Type and
.\"	name are examples of largest possible arguments that will be passed
.\"	to .AP later.  If args are omitted, default tab stops are used.
.\"
.\" .BS
.\"	Start box enclosure.  From here until next .BE, everything will be
.\"	enclosed in one large box.
.\"
.\" .BE
.\"	End of box enclosure.
.\"
.\" .CS
.\"	Begin code excerpt.
.\"
.\" .CE
.\"	End code excerpt.
.\"
.\" .VS ?version? ?br?
.\"	Begin vertical sidebar, for use in marking newly-changed parts
.\"	of man pages.  The first argument is ignored and used for recording
.\"	the version when the .VS was added, so that the sidebars can be
.\"	found and removed when they reach a certain age.  If another argument
.\"	is present, then a line break is forced before starting the sidebar.
.\"
.\" .VE
.\"	End of vertical sidebar.
.\"
.\" .DS
.\"	Begin an indented unfilled display.
.\"
.\" .DE
.\"	End of indented unfilled display.
.\"
.\" .SO ?manpage?
.\"	Start of list of standard options for a Tk widget. The manpage
.\"	argument defines where to look up the standard options; if
.\"	omitted, defaults to "options". The options follow on successive
.\"	lines, in three columns separated by tabs.
.\"
.\" .SE
.\"	End of list of standard options for a Tk widget.
.\"
.\" .OP cmdName dbName dbClass
.\"	Start of description of a specific option.  cmdName gives the
.\"	option's name as specified in the class command, dbName gives
.\"	the option's name in the option database, and dbClass gives
.\"	the option's class in the option database.
.\"
.\" .UL arg1 arg2
.\"	Print arg1 underlined, then print arg2 normally.
.\"
.\" .QW arg1 ?arg2?
.\"	Print arg1 in quotes, then arg2 normally (for trailing punctuation).
.\"
.\" .PQ arg1 ?arg2?
.\"	Print an open parenthesis, arg1 in quotes, then arg2 normally
.\"	(for trailing punctuation) and then a closing parenthesis.

.SH NAME
img-window \- Img, Tk Windows (window)
.SH SYNOPSIS
package require \fBTk \fR
.sp
package require \fBimg::window  ?1\&.4?\fR
.sp
\fBimage\fR \fBcreate photo\fR ?\fIname\fR? ?\fIoptions\fR?
.sp
.BE
.SH DESCRIPTION
The package \fBimg::window\fR is a sub-package of
\fBImg\fR\&. It can be loaded as a part of the complete Img support,
via \fBpackage require Img\fR, or on its own, via
\fBpackage require img::window\fR\&.
.PP
Like all packages of \fBImg\fR it does \fInot\fR provide new
commands, but extends the existing \fBTk\fR command \fBimage\fR\&.
More specifically
\fBimg::window\fR extends \fBTk\fR's \fBphoto\fR
image type\&.
.PP
The name of the new format handler is \fBwindow\fR\&.
.PP
This handler does not provide additional configuration options\&.
This handler is special\&. Instead of reading or writing image data from
a file or string it allows the embedding of a Tk widget into the photo
image\&. In other words, it takes a snapshot of the contents of a Tk
window\&.
.PP
All of the above means that in a call like
.TP
\fBimage\fR \fBcreate photo\fR ?\fIname\fR? ?\fIoptions\fR?
.PP
.IP [1]
Image data in window format (option \fB-data\fR) is
detected automatically\&. Image data is considered to be in the
\fBwindow\fR format if the value given to option
\fB-data\fR is the name of an existing Tk window\&.
.sp
Note that the standard option \fB-file\fR is not supported by this
handler\&.
.IP [2]
The format name \fBwindow\fR is recognized by the option \fB-format\fR\&.
.PP
