Package webpconv-0.0.5-2

WebP is a method of lossy compression that can be used on photographic images. The degree of compression is adjustable so a user can choose the trade-off between file size and image quality. A WebP file consists of VP8 image data, and a container based on RIFF. Webmasters, web developers and browser developers can use the WebP format to create smaller, better looking images that can help make the web faster.

This package is obsolete. Use the 'cwebp' and 'dwebp' utilities from 'libwebp0-bin' instead to convert to/from WebP files. Using webpconv to convert images Use webpconv on the command line to convert files to WebP or another format. The webpconv command has the following syntax: webpconv [-output_dir dir] [-format format] [-quality quality] input_file(s) Arguments -output_dir Path to directory where files are placed. If no path is specified, files are created in the input directory. -format Output image format. Valid formats are: BMP, JPEG, PNG, WEBP. -quality Integer. Parameter that specifies the trade off between the file size and the quality of the output image. The range is from 0 to 100; 100 is the best image quality with the largest file size. If no value is specified, the default quality value corresponds to a target peak signal-to-noise ratio (PSNR) value of 42. A PSNR value of 42 is usually regarded as a good quality image. Examples You can convert a PNG image in /home/user/images/ to a WebP image with a quality range of 80 with the command: webpconv -quality 80 /home/user/images/img.png You can convert a group of WebP images in /home/user/images/ to PNG and place them in the /tmp folder with the command: webpconv -output_dir /tmp -format PNG /home/user/images/*.webp
