Method Detail

setScaledImage

void setScaledImage(java.awt.image.RenderedImage image)

Sets the image represented by this GraphicScaledImage.

Parameters:

image - the image to be rendered.

getScaledImage

java.awt.image.RenderedImage getScaledImage()

Returns the image represented by this GraphicScaledImage.

Returns:

the image to be rendered.

setUpperCorner

void setUpperCorner(DirectPosition coord)

Convenience menthod to set the DirectPosition for the upper-right position of the image.

Parameters:

coord - the upper-right positon.

getUpperCorner

DirectPosition getUpperCorner()

Convenience menthod to return the DirectPosition for the upper-right position of the image.

Returns:

the upper-right position.

setLowerCorner

void setLowerCorner(DirectPosition coord)

Convenience menthod to set the DirectPosition for the lower-left position of the image.

Parameters:

coord - the lower-left positon.

getLowerCorner

DirectPosition getLowerCorner()

Returns the DirectPosition for the lower-left position of the image.

Returns:

the lower-left position.

setIntensity

void setIntensity(int intensity)

Sets the intensity of the image, as an integer from 0 to 100. The value 0 is as dark as possible and 100 is as bright as possible.

Parameters:

intensity - the intensity (brightness) of the image.

getIntensity

int getIntensity()

Returns the intensity of the image, as an integer from 0 to 100. The value 0 is as dark as possible and 100 is as bright as possible.

Returns:

the intensity (brightness) of the image .

setTransparency

void setTransparency(int transparency)

Sets the transparency of the image, as an integer from 0 to 100. The value 0 is completely opaque and 100 is completely transparent.

Parameters:

transparency - the transparency of the image.

getTransparency

int getTransparency()

Returns the transparency of the image, as an integer from 0 to 100. The value 0 is completely opaque and 100 is completely transparent.

Returns:

the transparency of the image.

setCRS

void setCRS(CoordinateReferenceSystem crs)

This sets the coordinate reference system that was used to create the image that this object represents.

Implementations of the GraphicScaledImage interface are not required to implement any particular projections (there are in fact hundreds of EPSG codes). When the projection of the GeoCanvas differs from that contained in the SRS of this object, the behavior of the image is undefined. An implementation may choose to simply not show the image or to attempt to stretch or warp the image to fit the current projection.

Precision issues may arise when a GeoCanvas needs to determine if a given SRS represents the same projection as it is currently displaying. Implementations are encouraged to store the SRS in an internal format that will allow projections whose center points are less than a meter apart on the earth's surface to be considered the same projection.

getCRS

CoordinateReferenceSystem getCRS()

Returns the coordinate reference system that was used to create the image this object represents.
