I'm currently using the JPGEncoder from the AS3 core lib to encode a bitmap to JPEG
var enc:JPGEncoder = new JPGEncoder(90);
var jpg:ByteArray = enc.encode(bitmap);
Because the bitmap is rather large (3000 x 2000) the encoding takes a long while (about 20 seconds), causing the application to seemingly freeze while encoding. To solve this, I need either:
- An asynchronous encoder so I can keep updating the screen (with a progress bar or something) while encoding
- An alternative encoder which is simply faster
Is either possible?
