Package: webp Version: 0.1-1 Severity: important cwebp(1) claims it can compress images into WebP format, and that "Input format can be either PNG, JPEG, or raw Y'CbCr samples". I can't test its handling of Y'CbCr format, since I've never seen any such files, but converting from PNG or JPEG fails:
jbr@xan:~$ cwebp png.png -o png.webp Saving file 'png.webp' PNG support not compiled. Please install the libpng development package before building. Error! Could not process file png.png jbr@xan:~$ cwebp jpg.jpg -o jpg.webp Saving file 'jpg.webp' JPEG support not compiled. Please install the libjpeg development package before building. Error! Could not process file jpg.jpg jbr@xan:~$ Grabbing a sample WebP file and trying the opposite direction: jbr@xan:~$ wget -q http://www.gstatic.com/webp/gallery/1.webp jbr@xan:~$ dwebp 1.webp -o 1.png Decoded 1.webp. Dimensions: 550 x 368. Now saving... PNG support not compiled. Please install the libpng development package before building. You can run with -ppm flag to decode in PPM format. Error writing file out.png !! jbr@xan:~$ At least these are good clear error messages! Although there's no need for a space before exclamation marks in English - and in fact, after you've introduced it as an "Error", even one exclamation mark is redundant, let alone two. However, good news: jbr@xan:~$ dwebp -ppm 1.webp -o 1.ppm Decoded 1.webp. Dimensions: 550 x 368. Now saving... Saved file 1.ppm jbr@xan:~$ That functionality's enough to save the package from being entirely useless, so I'll only rate this as an "important" bug, not "grave". There's also an obvious typo in the package's long description: "for the webp" should be "for the web". -- System Information: Debian Release: wheezy/sid APT prefers testing APT policy: (500, 'testing'), (50, 'unstable') Architecture: i386 (i686) Kernel: Linux 2.6.38-2-686 (SMP w/1 CPU core) Locale: LANG=en_GB.UTF-8, LC_CTYPE=en_GB.UTF-8 (charmap=UTF-8) Shell: /bin/sh linked to /bin/dash Versions of packages webp depends on: ii libc6 2.11.2-11 Embedded GNU C Library: Shared lib ii libwebp0 0.1-1 Lossy compression of digital photo webp recommends no packages. webp suggests no packages. -- debconf-show failed -- JBR Ankh kak!
