.\" 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-ico \- Img, Windows Icon Format (ico)
.SH SYNOPSIS
package require \fBTk \fR
.sp
package require \fBimg::ico  ?1\&.4?\fR
.sp
\fBimage\fR \fBcreate photo\fR ?\fIname\fR? ?\fIoptions\fR?
.sp
.BE
.SH DESCRIPTION
\fBpackage require img::ico\fR\&.
.PP
Like all packages of \fBImg\fR it does \fInot\fR provide new
commands, but extends the existing \fBTk\fR command \fBimage\fR so
that it supports files containing raster images in the
Windows Icon Format (ico)\&. More specifically
\fBimg::ico\fR extends \fBTk\fR's \fBphoto\fR
image type\&.
.PP
The name of the new format handler is \fBico\fR\&.
.PP
The package \fBimg::ico\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::ico\fR\&.
.PP
This handler provides new additional configuration options\&. See
section \fBICO OPTIONS\fR for more detailed explanations\&.
.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 ico format (options \fB-data\fR and \fB-file\fR) is
detected automatically\&.
.IP [2]
The format name \fBico\fR is recognized by the option \fB-format\fR\&.
In addition the value for the option is treated as list and may
contain any of the special options listed in section
\fBICO OPTIONS\fR\&.
.PP
.SH "SUPPORTED ICO TYPES"
