m a flag with no argument directing srcset.sh to pipe the resulting markup into a file. s specify the sizes attribute found in the tag the default is (min-width: 768px) 50vw, 100vw. Otherwise the files are saved to the directory of the specified input file path. o specify a destination directory for the files converted by srset.sh.
No -srcw file is created if a width is specified. Without, the default creates a copy of the original image with no resizing, appends the suffix -srcw such that the attribute resembles src="-srcw" followed by the extension. The resulting attribute references the specified width filename. l specify the width in pixels set within the src attribute that is utilized by legacy browsers not supporting srcset. q specify the quality from 1 (lowest image quality) to 100 (best quality) of compression used by srset.sh otherwise use the convert best fit for the source image. The prefix is not added to the converted files as a path. The prefix, pixel width and the suffix w is appended to the source filename such that the resulting filenames resembles the format, src="-XXXw." where XXX is the specified pixel width thus, one of -320w, -480w, -640w, -768w, -960w, -1024w, -1280w, -1440w. It is useful for specifying the release web root. p specify the prefix that will appear in front of an image within the src and srcset attributes. t specify the type of image conversion used by srset.sh defaults to the same type as the input based on the file's extension.
The pattern is passed to unix find and is equivalent to its name primary.
n specify the pattern for srset.sh to find when converting multiple images. The type of file path, whether file or file hierarchy is determined by srcset.sh. The directory will be traversed using the unix find command.
The file path may also be specified as the operands immediately following all the options. f specify a file path (single file or file hierarchy) for srcset.sh to convert. The srcset.sh utility generates multiple (eight) scaled versions of an image at particular breakpoints - 320,480,640,768,960,1024,1280,1440 pixels wide - that match common Mobile and widescreen viewports using Imagemagick's convert utility and outputs the needed tag.Ī file path, whether filename or file hierarcy is required. Srcset.sh - generate multiple responsive images for web and mobile.
