Solve the problem that WorldWind cannot correctly browse map slices.

Development Environment: worldwind.net 1.4.1

Cut the image data into graphs, but only cut 8-11 layers, 0-7 layers do not cut the image. Layer 0-7 is the administrative domain, so do not cut the graph.

The configuration file has 12 layers. The format is PNG.

Run ww and the image cannot be displayed.

Trace and debug WW, and find 318th rows in quadtile. CSCode:

If (newtexture = NULL)
{
// At least one texture missing, wait for download
Waitingfordownload = true;

}

If no image texture data is found, set waitingfordownload to true,ProgramThe data is waiting for download. Instead of skipping tile files of this level.

The solution is simple. Set waitingfordownload to false. In this way.

Re-run ww and the image tiles are out. Everything is normal.

Summary:

You do not have to cut an image or vector image from layer 0. You can cut it from any layer. You only need to ignore the failure to find the tile file in WW.
