Code

function testTransparentColorOutOfRange() {

  // This image was generated by taking an initial image with a palette size
  // of 6 colors, and setting the transparent color index to 6 (one higher
  // than the largest allowed index), as follows:
  // @code
  // $image = imagecreatefromgif('core/modules/simpletest/files/image-test.gif');
  // imagecolortransparent($image, 6);
  // imagegif($image, 'core/modules/simpletest/files/image-test-transparent-out-of-range.gif');
  // @endcode
  // This allows us to test that an image with an out-of-range color index
  // can be loaded correctly.
