java.lang.Objectnet.sourceforge.jiu.data.MemoryByteChannelImage
net.sourceforge.jiu.data.MemoryGray8Image
An implementation of Gray8Image
that keeps the complete image in memory.
This class inherits most of its functionality from its parent class
MemoryByteChannelImage
, using one byte channel.
Constructor Summary | |
MemoryGray8Image(int width,
int height)
Creates a new MemoryGray8Image object with the specified resolution. |
Method Summary | |
PixelImage |
createCompatibleImage(int width,
int height)
Creates an instance of the same class as this one, with width and height given by the arguments. |
Class |
getImageType()
If there is a single interface or class that describes the image data type of this class, the Class object associated with that
interface (or class) is returned (or null otherwise).
|
boolean |
isBlack(int x,
int y)
Returns if the pixel specified by the location in the arguments is black. |
boolean |
isWhite(int x,
int y)
Returns if the pixel specified by the location in the arguments is white. |
void |
putBlack(int x,
int y)
Sets a pixel to black (minimum intensity value). |
void |
putWhite(int x,
int y)
Sets a pixel to white (maximum intensity value). |

This Class
object, if available for two image objects,
can be used to find out if they are compatible.
Example: MemoryGray8Image
