change background color in product image thumb

-- HikaShop version -- : 2.3.5
-- Joomla version -- : 3.3.6
-- PHP version -- : 5.4
-- Browser(s) name and version -- : Safari 5.1.10

Hi Nicolas, (thank you for Hikashop, it's wonderful!)

I am trying to change the background color in my product image thumbnails. When they are not square, the default color appearing is white and I cannot figure out where to change it in the hikashop options or my css.

Hi Jerome, thank you for the helpful reply.

I have gone to the Hikashop component >Display>Views>Product> listing_img_title

and I have added the background command to the $image_options array. It now appears as follows:

_____

$image_options = array('default' => true,'forcesize'=>$this->config->get('image_force_size',true),'scale'=>$this->config->get('image_scale_mode','inside'),'background' => '#000000');

_____

I have also cleared my cache and reset Safari, but the appearance is the same. This has not changed the background color in my product thumbnails.

I have also gone to my image.php file ("administrator/components/com_hikashop/helpers/image.php") and found the line:
_____

$bgcolor = $this->_getBackgroundColor($thumb, @$options);
_____

is there a modification I must make here to 'background' to set the color to black instead of white?

IT'S FIXED!!!!

At first I thought this didn't work, but then...I learned that 255,255,255 is white and 0,0,0 is black. So I used:

	function _getBackgroundColor($resource, $color) {
		if(!empty($color)) {
			if(is_array($color)) {
				$bgcolor = imagecolorallocatealpha($resource, $color[0], $color[1], $color[2], 0);
				if($bgcolor === false || $bgcolor === -1)
					$bgcolor = imagecolorallocate($resource, $color[0], $color[1], $color[2]);
			} elseif( is_string($color) ) {
				$rgb = str_split(ltrim($color, '#'), 2);
				$bgcolor = imagecolorallocatealpha($resource, hexdec($rgb[0]), hexdec($rgb[1]), hexdec($rgb[2]), 0);
				if($bgcolor === false || $bgcolor === -1)
					$bgcolor = imagecolorallocate($resource, hexdec($rgb[0]), hexdec($rgb[1]), hexdec($rgb[2]));
			}
		}
		if(empty($bgcolor)) {
			$bgcolor = imagecolorallocatealpha($resource, 0, 0, 0, 0);
			if($bgcolor === false || $bgcolor === -1)
				$bgcolor = imagecolorallocate($resource, 0, 0, 0);
		}
		return $bgcolor;
	}
