.TH PNGTOICO 1 "1 January 2002" "pngtoico 1.0"
.SH NAME
.B pngtoico
\- convert png images to M$ ico format
.SH SYNOPSIS
.B pngtoico
.I files.png...
>
.I output.ico
.SH DESCRIPTION
.B pngtoico
converts a set of palettized (indexed) Portable Network Graphics (PNG)
files to a single Micro$oft icon (ICO) file.
.PP
Each input PNG image should be no larger than 255x255 pixels, and use
no more than 256 colours.  Fully transparent pixels are allowed;
partially transparent pixels (alpha blending) are not.
.SH NOTES
Although the ICO format is getting used on the web as a "favourites
icon" format, it is actually very ill-suited for that purpose.  Using
a <LINK> tag, PNG images can usually be specified instead.  The use of
PNG images is recommended.
.SH BUGS
The ICO format is space-consuming and full of limitations.
