Description #description

To get an optimal display for the signature in our PDFs we decrease the size of the image by about 66%. This creates a signature at a good size and resolution in your PDF. However, you can use this filter to make a signature smaller or larger.

Parameters #parameters

$optimised_width | mixed
The optimal width of the signature for quality. Reduced by 66% of the original size.
$original_width | string
The original width of the signature in pixels.

Usage #usage

This snippet shows you how you increase the signature size and instead only reduce the width by 50%:

add_action( 'gfpdf_signature_width', function( $optimised_width, $original_width ) {
    return $original_width / 2;
}, 10, 2 );

Source Code #source-code

This filter is located in the Field_Signature::value() method of /src/helper/fields/Field_Signature.php.
