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