image_resize_dimensions filter-hook . WP 3.4.0

Filters whether to preempt calculating the image resize dimensions.

Returning a non-null value from the filter will effectively short-circuit image_resize_dimensions(), returning that value instead.

Usage

add_filter( 'image_resize_dimensions', 'filter_function_name_6145', 10, 6 );
function filter_function_name_6145( $null, $orig_w, $orig_h, $dest_w, $dest_h, $crop ){
	// filter...

	return $null;
}

$null(null/mixed)

Whether to preempt output of the resize dimensions.

$orig_w(int)

Original width in pixels.

$orig_h(int)

Original height in pixels.

$dest_w(int)

New width in pixels.

$dest_h(int)

New height in pixels.

$crop(true/false/array)

Whether to crop image to specified width and height or resize. An array can specify positioning of the crop area.
