grunt-cwebp's Issues

lossless

Hi,
I tried to use grunt cwebp with "lossless" set with "true", but the task returns an error:
Warning: Command failed: /pat/to/cwebp path/to/img.jpg -o path/to/img.webp -q 92 -lossless true cannot open input file 'true' Error! Could not process file true Error! Cannot read input picture file 'true'

Can you help me to set properly my grunt task, please?

Tnx.

Doesn't work with grunt-newer

Grunt-newer doesn't work with grunt-cwebp. This is my configuration:

cwebp: {
    my_target: {
        options: {
            q: 65
        },
        files: [{ // converting all files in webp formate in "assets/img" folder dynamically to relavant folder
        	expand: true,
            cwd: 'assets/img',
            src: ['**/*.{png,jpg}'],
            dest: 'dist/webp/'
        }]
    }
}

Please help, its working fine with grunt-contrib-imagemin

pictures with gradient

Hi,
by running grunt cwebp, we noticed that images with a gradient are ruined. What parameters can be used to solve the problem?
We tried "alpha_filter" with "best" or "none", but it doesn't solve the issue.

("q" parameter is set to 92)

Tnx a lot.

Add option for extension change to .webp

Hi,

Would be great to have a .webp files on output, to separate them from source files.
