Usage

imagene --help

Syntax:
    imagene <infile> ...<flag>... ...<action>:<value>... <outfile>

Available Actions:
    brightness:<int>             -> Increase brightness by percent
    contrast:<int>               -> Increase contrast by percent
    blur:<float>                 -> Add gaussian blur by sigma (recommended 1-20)
    unsharpen:<float,int>        -> Add unsharpen mask with float being sigma and int being threshold
    invert:<true/false>          -> Invert colors of image
    flip:<v/h>                   -> Flip image v for vertically or h for horizontally
    rotate:<left/right/down>     -> Rotate an image by 90,180,270 degrees
    resize:<int,int>             -> Resize an image, leave one of the ints empty to auto scale it
    crop:<int,int,int,int>       -> Crop an image (x,y,width,height)
    append:<string,left/under>   -> Add another image next to source image
    text:<string,(x:y),(r:g:b:a),(font,scale)>  -> Add text onto an image, where font is a path to .ttf file. All values are float
    format:<string>              -> Specify output image format
    format:<jpg,int>             -> For JPG, also specify quality

Available Flags:
    lanczos3   -> Use a slower but possibly higher quality algorithm

Examples:
     -> Increases the contrast of the original image by 20% and adds an extra image next to it
     imagene in_file.png contrast:20 append:extra_image.png,left out_file.png

     -> Set width to 2000, automatically scales height to keep aspect ratio and output to STDOUT
     imagene in_file.png resize:2000,0 stdout

     -> Overwrites an image with increased contrast
     imagene in_file.png contrast:2 in_file.png

TODO:

• An TODO list
• Write documentation and add examples
• Add more comments to cli.rs
• Improve transparency on text action
• Add color flag that can be used to convert between color modes
• Package for Void and Arch Linux
