I am working on a GIS API that uses OpenLayers 2. I want to make snapshots of a selected region. For example. I draw a rectangle, and the MapFish Printing Module would print only the selected region.
I have been trying to use the bbox property, but I get the wrong image, i.e., instead of a rectangle near Lisbon, I get a rectangle with south Europe and North/Center Africa.
Here are my print options:
var printOptions = { units: 'm', srs: 'EPSG:900913', layout: options.layout, dpi: '300', mapTitle: options.mapTitle, comment: options.comment, layers: [ { baseURL: 'http://a.tile.openstreetmap.org/', opacity: 1, singleTile: false, type: 'OSM', maxExtent: [-20037508.3392, -20037508.3392, 20037508.3392, 20037508.3392], tileSize: [256, 256], extension: 'png', resolutions: [156543.03390625, 78271.516953125, 39135.7584765625, 19567.87923828125, 9783.939619140625, 4891.9698095703125, 2445.9849047851562, 1222.9924523925781, 611.4962261962891, 305.74811309814453, 152.87405654907226, 76.43702827453613, 38.218514137268066, 19.109257068634033, 9.554628534317017, 4.777314267158508, 2.388657133579254, 1.194328566789627, 0.5971642833948135] } ], pages: [ { bbox: [-1050091.8944356, -990623.88643799, 4675576.582525099, 4733515.8499572] } ]};I am assuming that the bbox array is defined like this: [minX, maxX, minY, maxY]. Is this correct?
Would you please help me solve this?
