#Imageoptim vs optipng mac#

It’s the best for publishing images on the web (easily compress pictures “Saved for Web” in Photoshop) and also helpful for making Mac and iPhone/iPad applications smaller. ImageOptim seamlessly integrates with tons of the best optimisation tools: PNGOUT, Zopfli, Pngcrush, AdvPNG, extended OptiPNG, JpegOptim, jpegrescan, jpegtran, and Gifsicle. See LICENSE.txt for details.ImageOptim optimises images – so they take up less disk space and load faster – by finding best compression parameters and by detaching pointless comments and colour profiles. :interlace - Turn interlacing on (defaults to false)Ĭopyright (c) 2012-2014 Ivan Kuchin.:jpegrescan - Use jpegtran through jpegrescan, ignore progressive option (defaults to false).:progressive - Create progressive JPEG file (defaults to true).:copy_chunks - Copy all chunks (defaults to false).

:max_quality - Maximum image quality factor 0.:strip - List of extra markers to strip: :comments, :exif, :iptc, :icc or :all (defaults to :all).:level - Compression level: 0 - don't compress, 1 - fast, 2 - normal, 3 - extra, 4 - extreme (defaults to 4).:interlace - Interlace, true - interlace on, false - interlace off, nil - as is in original image (defaults to false).:level - Optimization level preset: 0 is least, 7 is best (defaults to 6).:strategy - Strategy: 0 - xtreme, 1 - intense, 2 - longest Match, 3 - huffman Only, 4 - uncompressed (defaults to 0).:copy_chunks - Copy optional chunks (defaults to false).:brute - Brute force try all methods, very time-consuming and generally not worthwhile (defaults to false).:fix - Fix otherwise fatal conditions such as bad CRCs (defaults to false).:chunks - List of chunks to remove or :alla - all except tRNS/transparency or :allb - all except tRNS and gAMA/gamma (defaults to :alla).Worker can be disabled by passing false instead of options hash. :verbose - Verbose output (defaults to false).:threads - Number of threads or disable (defaults to number of processors).image_optim.yml in current working directory $XDG_CONFIG_HOME/image_optim.yml (by default ~/.config/image_optim.yml).ConfigurationĬonfiguration in YAML format will be read and prepanded to options from two paths: Image optimization can be time consuming, so depending on your deployment process you may prefer to optimize original asset files.

If you cannot install to common location, then install to custom one and add it to PATH. Simplest way for image_optim to locate binaries is to install them in common location present in PATH (see Binaries installation). If you want to check latest changes: gem ' image_optim ', :git => ' git:///toy/image_optim.git ' Binaries location With version: gem ' image_optim ', ' ~> 0.11 '
