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. - -WWW: http://enlightenment.sourceforge.net/Libraries/Epeg/ +epeg is a convenient, fast library that uses libjpeg to: load JPEG +images destined to be turned into thumbnails; save and retrieve +thumbnail information; and manage loading of the image, ready for +scaling, with the minimum of overhead. + +epeg loads and scales large JPEG images very quickly, with a speed-up +proportional to the difference in the number of pixels in the source +image and the thumbnail.
