ImageFX Plugin

ImageFX allows you to add filters to your WordPress images uploaded through the normal media uploader.

For more information:
http://ottopress.com/2011/customizing-wordpress-images-with-a-plugin-imagefx/

Example:

Default filters:

• Greyscale with except Blue, Red, Green
• Sepia tone with 6 alternatives
• Colorize with red, yellow, green, blue, purple
• Photonegative
• Emboss & Emboss Edge
• Brighten (50, 100)
• Gaussian Blur & Selective Blur
• Mean Removal
• Smooth
• Negative
• Contrast Negative and Positive
• Rounded Corners

ImageFX is expandable and retractable, so removing and adding other filters using your own customized image manipulation functions is easy.
Register new filters with:

• Individually: imagefx_register_filter( ‘filter_name’, ‘cb_function’); //Note: cb_function defaults to imagefx_filter_{filter_name}
• Bulk: imagefx_register_filters( array( ‘filter_name’, ‘filter_name’ ) );

Unregister existing filters with:

• Individually: imagefx_unregister_filter( ‘filter_name’ );
• Collectively: imagefx_unregister_filters( array( ‘filter_name’, ‘filter_name’) );
• Specifically: imagefx_unregister_colorize_filters(); & imagefx_unregister_greyscale_filters(); & imagefx_unregister_sepia_filters(); imagefx_unregister_rounded_filters();
