Hi -
When defining a custom Projection using GWT 1.5.2 and gwt-maps-1.0
RC1, I can't seem to get around this:

My projection class:
public class NorthmoorMapProjection extends Projection {
int imageDimension = 65536;
int maxZoom = 5;
int tileSize = 256;
Point[] pixelOrigin = new Point[maxZoom];
int[] pixelsPerLonDegree = new int[maxZoom];
int[] tileBounds = new int[maxZoom];
boolean isWrapped = false;
public NorthmoorMapProjection() {
int currentTileSize = this.tileSize;
int currentTileBounds = 1;
for (int zoomLevel = 0; zoomLevel < this.maxZoom; zoomLevel++) {
int tileCenter = currentTileSize / 2;
this.pixelsPerLonDegree[zoomLevel] = currentTileSize /
360;
this.pixelOrigin[zoomLevel] =
Point.newInstance(tileCenter,
tileCenter);
this.tileBounds[zoomLevel] = currentTileBounds;
currentTileSize *= 2;
currentTileBounds *= 2;
}
}
@Override
public Point fromLatLngToPixel(LatLng latLng, int zoomLevel) {
Point pixelOrigin = this.pixelOrigin[zoomLevel];
int pixelOriginX = pixelOrigin.getX();
int pixelOriginY = pixelOrigin.getY();
int pixelsPerLonDegreeForCurrentZoom =
this.pixelsPerLonDegree[zoomLevel];
double currentLongitude = latLng.getLongitude();
double currentLatitude = latLng.getLatitude();
long newX = Math.round(pixelOriginX + currentLongitude *
pixelsPerLonDegreeForCurrentZoom);
long newY = Math.round(pixelOriginY + (-2 * currentLatitude) *
pixelsPerLonDegreeForCurrentZoom);
int newXint = new Long(newX).intValue();
int newYint = new Long(newY).intValue();
return Point.newInstance(newXint, newYint);
}
@Override
public LatLng fromPixelToLatLng(Point point, int zoomLevel, boolean
unbounded) {
Point pixelOrigin = this.pixelOrigin[zoomLevel];
int pixelOriginX = pixelOrigin.getX();
int pixelOriginY = pixelOrigin.getY();
int pixelsPerLonDegreeForCurrentZoom =
this.pixelsPerLonDegree[zoomLevel];
int currentX = point.getX();
int currentY = point.getY();
double d = currentX - pixelOriginX /
pixelsPerLonDegreeForCurrentZoom;
double e = -0.5 * (currentY - pixelOriginY) /
pixelsPerLonDegreeForCurrentZoom;
return LatLng.newInstance(e, d, unbounded);
}
@Override
public double getWrapWidth(int zoomLevel) {
return this.tileBounds[zoomLevel] * this.tileSize;
}
@Override
public boolean tileCheckRange(TileIndex index, int zoomLevel, int
tileSize) {
int tileBounds = this.tileBounds[zoomLevel];
int newX = index.getX();
if (index.getY() < 0 || index.getY() >= tileBounds) {
return false;
}
if (this.isWrapped) {
if (index.getX() < 0 || index.getX() >= tileBounds) {
newX = index.getX() % tileBounds;
if (index.getX() < 0) {
newX += tileBounds;
}
}
} else {
if (index.getX() < 0 || index.getX() >= tileBounds) {
return false;
}
}
return true;
}
Any thoughts? Thanks!
Tim
