read() [1/2]

QList< QImage > ICOReader::read ( QIODevice * device )

static

Reads all the icons from the given device, and returns them as a list of QImage objects.

Each image has an alpha channel that represents the mask from the corresponding icon.

write() [1/2]

bool ICOReader::write ( QIODevice * device, const QList< QImage > & images )

static

Writes all the QImages in the images list to the given device.

Returns true if the images are written successfully; otherwise returns false.

The first image in the list is stored as the first icon in the device, and is therefore used as the default icon by applications. The alpha channel of each image is converted to a mask for each corresponding icon.
