class  image::cache_type< T >
class  image::locator
struct  image::locator::value
struct  image::manager
 the image manager is responsible for setting up images, and destroying all images when the program exits. More...


 this module manages the cache of images.

  image::UNSCALED, image::SCALED_TO_ZOOM, image::HEXED, image::SCALED_TO_HEX,
 UNSCALED : image will be drawn "as is" without changing size, even in case of redraw SCALED_TO_ZOOM : image will be scaled taking zoom into account HEXED : the hex mask is applied on the image SCALED_TO_HEX : image will be scaled to fit into a hex, taking zoom into account TOD_COLORED : same as SCALED_TO_HEX but ToD coloring is also applied BRIGHTENED : same as TOD_COLORED but also brightened.
