Filter for contrast parameter | WordPress.org

Hey there!

Love the plugin – integrated it into my project to get a jquery based fade to grayscale. Totally Sweet!

For my purposes, though, your scaler param (of .7?) in the function call “imagegammacorrect” on line 63 was a little too intense. The picture was of people outside and the high contrast made them look too sinister!! 🙂

I upped it to 1.2 and it looks great. Was wondering if you could include an option or WP filter to adjust the effect.

Thanks man!

Hi purcebr

I have updated the plugin to add a grayscale_gamma_correction filter.

Please let me know if this is what you need.

Hi there,
Nice feature.
How can I add my own parameter without hacking the plugin core?

@the_alien_01 : You have to use the add_filter function with the grayscale_gamma_correction to change the default value.

For example :
```
add_filter('grayscale_gamma_correction', 'fab1en_custom_gamma');
function fab1en_custom_gamma($gamma){
    return 0.9;
}
```
