An IMMENSELY FAST JPEG thumbnailer library API.
|
|
|
|
Why write this? It's a convenience library API to using libjpeg to load JPEG
|
|
images destined to be turned into thumbnails of the original, saving
|
|
information with these thumbnails, retreiving it and managing to load the image
|
|
ready for scaling with the minimum of fuss and CPU overhead.
|
|
|
|
This means it's insanely fast at loading large JPEG images and scaling them
|
|
down to tiny thumbnails. It's speedup will be proportional to the size
|
|
difference between the source image and the output thumbnail size as a
|
|
count of their pixels.
|
|
|
|
It makes use of libjpeg features of being able to load an image by only
|
|
decoding the DCT coefficients needed to reconstruct an image of the size
|
|
desired. This gives a massive speedup. If you do not try and access the pixels
|
|
in a format other than YUV (or GRAY8 if the source is grascale) then it also
|
|
avoids colorspace conversions as well.
