turbojpeg

问题 The instructions for libjpeg-turbo here describes the TurboJPEG API thus: "This API wraps libjpeg-turbo and provides an easy-to-use interface for compressing and decompressing JPEG images in memory". Great, but are there some solid examples of using this API available? Just looking to decompress a fairly vanilla jpeg in memory. I've found a few bits such as https://github.com/erlyvideo/jpeg/blob/master/c_src/jpeg.c, which appears to be using the TurboJPEG API, but are there any more solid

问题 First, what I (want to) do: compress and scale down an batch of pictures (jpg). Lets assume the original picture has this 1600w x 1200h dimensions. Now, i want to have one compressed copy of 1600x1200 and another 800x600 and 400x300. What I use: I'm using the libJpegTurob to achieve this. If the LibJpegTurob has some problem I try to use the android given methods. Already tried: First, I used the Java Wrapper ported from Tom Gall (https://github.com/jberkel/libjpeg-turbo). It went pretty fine
