[closed] Scrolling from one map to the next, improvement request
Posted: Sat Aug 30, 2014 10:45 am
I'm creating my own set of GB OS maps in AQM format.
In the latest version of AlpineQuest, an adjacent AQM file is automatically loaded when I scroll off one file and into the next. That's great, thank you for adding that.
However, the display past the edge of the 'current' file is still blank on the screen, rather than seamlessly displaying the map/file adjacent to it. When the next file is scrolled into and displayed, the first map area now goes blank. Does that make sense?
If I was working near the border of the two files, I would only ever be able to see one half at a time and the other half of the screen would be blank. Thinking about it, If I go to the very corner of a file, then I will only see a quarter of the potential map area.
Would it be possible to get data from the two to four files to load simultaneousness when the edge is reached, to give a seamless map view in the cross-over area? Even if that had a performance hit, it would be better than only having a partial view of the area.
Of course it's easy to say 'just load the four files' - I've no idea how hard that is from a programming viewpoint. I think it would be a very worthwhile improvement though.
The only workaround I can think of if it's not possible is for me to overlap all of my files' edges but that will dramatically increase the size of the set.
I'm going to pause my map-making in case you say this is possible in the near future...
