Direct Known Subclasses:

OMBitmap, OMRaster

public abstract class OMRasterObject
extends OMGraphicAdapter
implements OMGraphic, java.awt.image.ImageObserver

The OMRasterObject is the parent class for OMRaster and OMBitmap objects. It manages some of the same functions that both classes require in order to create image pixel data from bytes or integers.

An ImageFilter may be applied to OMRasterObjects. These can be scale filters, color filters, or maybe (?hopefully?) projection filters. These filters won't change the original image data, and the original can be reconstructed by resetting the filter to null, and generating the object.

For all classes in the OMRasterObject family, a java.awt.Shape object is created for the border of the image. This Shape object is used for distance calculations. If the OMRasterObject is selected(), however, this Shape will be rendered with the OMGraphic parameters that are set in the OMGraphic.

Constant Field Values

colorModel

protected int colorModel

colorModel helps figure out what kind of updates are necessary, by knowing what kind of image we're dealing with. For the images created with a ImageIcon, the attribute updates that don't relate to position will not take affect.

pixels

protected int[] pixels

The pixels are used for the image that is drawn on the window. The pixels are either passed in as an int[] in some constructors of the OMRaster, or it is constructed in the OMBitmap and in OMRasters that have a colortable.

x

protected int x

Horizontal location of the upper left corner of the image, or the x offset from the lon for that corner, in pixels.

y

protected int y

Vertical location of the upper left corner of the image, or the y offset from the lat for that corner, in pixels.

lat

protected double lat

The latitude of the upper left corner for the image, in decimal degrees.

lon

protected double lon

width

protected int width

height

protected int height

The height of the image, in pixels. This always reflects the height of the original image, even if a filter is applied to the image.

bits

protected byte[] bits

The byte info for the image. OMBitmaps use each bit as an indication to use the lineColor or the fillColor for each pixel (like a XBitmap). OMRasters only use the bits when the image being created follows the indexed colormodel. Then, the bits hold the colortable indexes that each pixel needs to have a color substituted in later.

bitmap

protected transient java.awt.Image bitmap

The bitmap is drawn to the graphics.

point1

protected transient java.awt.Point point1

Projected window pixel location of the upper left corner of the image.

filteredHeight

protected int filteredHeight

The height of the image after scaling, if you want the image to be a different size than the source.

imageFilter

protected java.awt.image.ImageFilter imageFilter

The image filter to use on the constructed image.

needToReposition

protected boolean needToReposition

Set if the projection has had attributes change that require a repositioning of the image, not a regeneration.

rotationAngle

protected double rotationAngle

the angle by which the image is to be rotated, in radians

renderRotationAngle

protected java.lang.Double renderRotationAngle

The angle, perhaps taking into account NO_ROTATE, that the image is rotated at render-time.

anchorY - the y coordinate of the rotation point.
