Class

ImageToolkitGdTestCase

Test the core GD image manipulation functions.

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
    // $image = imagecreatefromgif('modules/simpletest/files/image-test.gif');
    // imagecolortransparent($image, 6);
    // imagegif($image, '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.
    $file = 'image-test-transparent-out-of-range.gif';
