All Implemented Interfaces:

java.io.Serializable

public class AimsMap

extends java.lang.Object

implements java.io.Serializable

The AimsMap class contains the complete instance of an ArcIMS map service, and modifications to the map layers, etc. that have been done during an application session. If the current state of the map is needed in subsequent pages, this object should be stored in the session object.

                         double y2)

Sets the map extent to user coordinates.

Parameters:

x1 - The minimum X coordinate (mapunits)

y1 - The minimum Y coordinate (mapunits)

x2 - The maximum X coordinate (mapunits)

y2 - The maximum Y coordinate (mapunits)

zoomToPreviousExtent

public void zoomToPreviousExtent()

Sets the map extent to an extent from the previous extent stack, and removes the extent from the stack.

zoomToMapsheet

public void zoomToMapsheet(java.lang.String mapsheet)

Sets the map extent to the extent of a mapsheet.

Parameters:

mapsheet - The mapsheet to zoom to

getScale

public double getScale(double scaleFactor)

Gets the map scale of a given scaleFactor if the mapunits are metres. The scaleFactor is the pixels per metre for metric sources. The ESRI threshold routines use a fixed resolution value of approximately 97.6925 pixels per inch to calculate scale when doing the thresholding.

Parameters:

scaleFactor - The scale factor to calculate map scale for.

Returns:

The map scale

getScaleFactor

public double getScaleFactor(double scale)

Gets the mapunits per pixel map scale factor for a given map scale. This value is used internally in the minscale and maxscale routines used by the server. The ESRI routines use a fixed resolution value of approximately 97.6925 pixels per inch to calculate scale when doing the thresholding.

Returns:

The mapunits per pixel scale factor.

getScale

public double getScale()

Gets the map scale if the mapunits are metres. The ESRI threshold routines use a fixed resolution value of approximately 97.6925 pixels per inch to calculate scale when doing the thresholding, so this routine uses the same values.

Returns:

The map scale

getScaleFactor

public double getScaleFactor()

The mapunits per pixel map scale factor. This value is used internally in the minscale and maxscale routines used by the server.

Returns:

The mapunits per pixel scale factor.

setScale

public void setScale(double scale)

Sets the map to the specified scale

Parameters:

scale - The scale. For example 20000 indicates that the scale should be set to 1:20000.

doZoom

public void doZoom(double mapX,
                   double mapY,
                   double zoomFactor)

Changes the extent of the map, leaving the centre point the same. If the zoomFactor is less than 1.0, the map will zoom in, otherwise it will zoom out. For example, a zoomFactor of 2.0 will zoom out 2 times, a zoom factor of 0.5 will zoom in 2 times, and a zoomFactor of 1.0 will not zoom at all.

Parameters:

mapX - The map centre x coordinate.

zoomFactor - A number that determines the relative scale for the map.

centerAt

public void centerAt(double mapX,
                     double mapY)

re-centre the map at the (x,y) in map units

Parameters:

mapX - centre point x coordinate, in mapunits

mapY - centre point y coordinate, in mapunits

setAxlAttribute

public void setAxlAttribute(java.lang.String tag,
                            java.lang.String name,
                            java.lang.String value,
                            java.lang.String server)

Sets one of the attributes of this object using a string value. This method can only be called from the SAX event handler.

Parameters:

tag - The AXL element tag containing this attribute.

name - The AXL attribute name.

value - The AXL attribute value.

toString

public java.lang.String toString()

Returns a text representation of of this class.

Returns:

A string describing the class

setMaximumScale

public void setMaximumScale(double scale)

setMinimumScale

public void setMinimumScale(double scale)

getMapTransform

public java.awt.geom.AffineTransform getMapTransform()

Returns an AffineTransform for use to convert page units to map units.

Returns:

An AffineTransform for use to convert page units to map units.

getPageTransform

public java.awt.geom.AffineTransform getPageTransform()

Returns an AffineTransform for use to convert map units to page units.

Returns:

An AffineTransform for use to convert map units to page units.

getImageUrl

public java.lang.String getImageUrl()

getImage

public java.awt.image.BufferedImage getImage()
