Hello dear sir,
I have a problem to consult you. I make a TMS demo, restrict the map to a
specific bound, and use a maxResolution. My codes are as follows. But it
display "lack of image"(some 256*256 red box with a cross) in the region where
there are out of the bound. How to control it, and do not let it display "lack
of image"? Using the parameter "maxResolution"? How to calculate the value of
the "maxResolution" of a TMS layer? Thank you very much!
var bounds = new
OpenLayers.Bounds(103.944322120274,30.633607944233,104.154306379013,30.8435922029719);
......
var map_options={
controls:[new OpenLayers.Control.MouseDefaults()]
,'maxExtent': bounds
,'projection': 'EPSG:4326'
,numZoomLevels: 3
,maxResolution:0.00082025101069921875
,units: "degrees"
};
map = new OpenLayers.Map( 'map' , map_options );
var tms_options={
layername: 'basic'
, type:'jpg'
,'maxExtent': bounds
,displayOutsideMaxExtent: false
};
layer = new OpenLayers.Layer.TMS( "TMS",
"http://localhost:8080/functions/";, tms_options );
