The visual dimension of the view area is fixed for both the cases that is, 300px by 300 px. The, view point in this example. (240 260), is also same in both the cases. However because we, have viewed the normal screen in 1.3 and zoomed it to X4. In case of 1.6 the real, coordinate (img.ext) in this case show two different values.When we zoom on, the map sever generates new map for shown. We can observe in. Tmp folder. Although img.x img.y of,, step 1.3 and 1.6 is 240 260 too,,, But attributes is different. Moreover imgext, changes. Summing, it up img.x img.y of, step 1.3 and 1.6 is different position. On the map because zoom get new image that get new imgext. New Imgext of new image is calculated new img. X and img.y.Because scale have an effect on define position on map. When the scale change the object on map then.Change and when query old location with new scale. The object on map will show new position.1.3 and 1.6 covers and different area.1.3 cover areas more than 1.6 and when zoom in 2 steps sever generates new map for show.The position of the details shown on the map and imgext, to change.
