[mkgmap-dev] Commit: r1367: Rewrite pickArea() to avoid a problem with unequally sized areas.From svn commit svn at mkgmap.org.uk on Wed Nov 11 11:21:31 GMT 2009
Version 1367 was commited by markb on 2009-11-11 11:21:31 +0000 (Wed, 11 Nov 2009) Rewrite pickArea() to avoid a problem with unequally sized areas. The original pickArea() assumed that all the areas to choose from had the same widths and the same heights. Unfortunately, that is not true and so it was occasionally putting elements in the wrong area. This new version simply iterates through the areas testing to see if the element is contained within one. It may be slower for large numbers of areas but at least it should get the answer right. Mind you, I don't think the number of areas is ever that large because the subdivision process just divides areas by something small like 2 or 4. So probably not really slower at all. Also, it now throws away elements that are outside of the whole area and emits an error message.
