Advanced Decoding API:
|
||||
=========================
|
||||
|
||||
WebP decoding supports Advanced API to provide ability to have on-the-fly
|
||||
cropping and rescaling, something of great usefulness on memory-constraint
|
||||
environments like mobile phones. Basically, the memory usage will scale with
|
||||
the output's size, not the input's when one only need a quick preview or a
|
||||
zoomed in portion of an otherwise too-large picture. Some CPU can be saved
|
||||
too, incidentally.
|
||||
|
||||
-------------------------------------- BEGIN PSEUDO EXAMPLE

||||
// A) Init a configuration object
|
||||
WebPDecoderConfig config;
|
||||
CHECK(WebPInitDecoderConfig(&config));

|
||||
// B) optional: retrieve the bitstream's features.

||||

// D) Specify 'config' output options for specifying output colorspace.
|
||||
// Optionally the external image decode buffer can also be specified.
|
||||
config.output.colorspace = MODE_BGRA;
|
||||
// Optionally, the config.output can be pointed to an external buffer as
|

// well for decoding the image. This externally supplied memory buffer
