00011 // You can use QImageIO::setParameters() to request a specific
00012 // Icon out of an .ico file:
00013 //
00014 // Options consist of a name=value pair and are separated by a semicolon.
00015 // Available options are:
00016 //     size=<size>   select the icon that most closely matches <size> (pixels)
00017 //                   default: 32
00018 //     colors=<num>  select the icon that has <num> colors (or comes closest)
00019 //                   default: 1 << display depth or 0 (RGB) if display depth > 8
00020 //     index=<index> select the indexth icon from the file. If this option
00021 //                   is present, the size and colors options will be ignored.
00022 //                   default: none
00023 // If both size and colors are given, size takes precedence.
00024 // 
00025 // The old format is still supported:
00026 //     the parameters consist of a single string in the form
00027 //     "<size>[:<colors>]" which correspond to the options above
00028 //
00029 // If an icon was returned (i.e. the file is valid and the index option
00030 // if present was not out of range), the icon's index within the .ico
00031 // file is returned in the text tag "X-Index" of the image.
00032 // If the icon is in fact a cursor, its hotspot coordinates are returned
00033 // in the text tags "X-HotspotX" and "X-HotspotY".
