Detailed Description

The ThumbnailManager class generates and manages thumbnails for data instances.

For most image data a thumbnail is generated by rendering the image (the middle slice in 3d). For other data, standard icons are returned. Generated thumbnails are cached.

void	removeFromCache (const Data *data)
	Removes any thumbnail for the given dataset from the cache.
void	setClearColor (vec4f c)
	Sets the background color of the thumbnail.
std::unique_ptr< SharedImage >	renderThumbnail (const SharedImageSet *image, const vec2i &size, const vec4f &clearColor={0, 0, 0, 0})
	Renders a thumbnail as SharedImage for the given image without using the cache.
QImage	getThumbnail (const Data *data, QSize size)
	Returns a thumbnail as QImage for the given data instance.
