After the last time a Shanghai map format to transfer from the wor gst then into wms, that can be used, but every time you click on the map, we need 5-6 seconds generation time, it became a in efficiency problem. Mainly caused by too many layers display, the picture generated more than 100 K.
To a large picture, in many cases pictures layers:
Finally a little empty, and I will start thinking about how to reduce the display layer.
After morning found under MapInfo after the installation of the Workspace Manage there have control of the display layer. First on a map:
When click on the layer: below Display the Within the Range , the check mark, the layer can be set in the range of visible scaling of 0.00 to> of 4.00 m.
As confirmed layer: through the front of the layers "hook" (or not displayed) changes in viewing the map, to confirm which layer.
For when the layer is controlled by its own coding scheme:
= To true by Layer.VisibleRangeEnabled;
. Layer.VisibleRange property or method
Control.
