Arguments

The following arguments are passed to functions that use this hook:

$size | int

• The image choices size (in pixels)
• The default value is either 150 200 or 300

$form | array

• The raw Gravity Forms form array

$entry | array

• The raw Gravity Forms Entry array.

Usage

Override the image choices size and set to 100px:

add_filter( 'gfpdf_image_choice_width', function( $size, $form, $entry, $pdf_settings ) {
  return 100; // set the image width to 100px
}, 10, 4 ); 

Only override the image choices size on a specific form:

add_filter( 'gfpdf_image_choice_width', function( $size, $form, $entry, $pdf_settings ) {
  if ( (int) $form['id'] !== 20 ) {
    return $size;
  }
   
  return 100; // set the image width to 100px on PDFs generated on form ID 20
}, 10, 4 );
