Works with Regional Maps: Download only the countries you need. HH-Routing seamlessly calculates routes across the borders of your downloaded map files (as long as they are compatible, see limitations). Clusters that overlap a region's boundary are included within that region's data.
If the number of candidates for each pixel grows too large (as is common in algorithms such as Knoll and Yliluoma) then sorting the candidate list for every pixel can have a significant impact on performance. A solution is to instead sort the palette in advance and keep a separate tally of weights for every palette colour. The weights can then be accumulated by iterating linearly through the tally of sorted colours.，更多细节参见快连下载安装
