|
// The icon decoder is a decoder specifically tailored for loading icons
|
|
// from the OS. We've defined our own little format to represent these icons
|
|
// and this decoder takes that format and converts it into 24-bit RGB with
|
|
// alpha channel support. It was modeled a bit off the PPM decoder.
|
|
//
|
|
// Assumptions about the decoder:
|
|
// (1) We receive ALL of the data from the icon channel in one OnDataAvailable
|
|
// call. We don't support multiple ODA calls yet.
|
|
// (2) the format of the incoming data is as follows:
|
|
// The first two bytes contain the width and the height of the icon.
|
|
// The remaining bytes contain the icon data, 4 bytes per pixel, in
|
|
// ARGB order (platform endianness, A in highest bits, B in lowest
|
|
// bits), row-primary, top-to-bottom, left-to-right, with
|
|
// premultiplied alpha.
