Class IJImage

java.lang.Object
  org.shapelogic.imageutil.IJImage

All Implemented Interfaces:

PixelHandler, SLImage

public class IJImage
extends java.lang.Object
implements SLImage

Abstraction of ImageJ ImageProcessor.
The other main implementation should probably be build on top of BufferedImage.

Method Summary

int	get(int index)
int	get(int x, int y) This is a faster version of getPixel() that does not do bounds checking.
java.awt.Rectangle	getActiveRectangle() This mean that the whole images is available in the pixels array.
int	getHeight() Returns the height of this image in pixels.
ij.process.ImageProcessor	getImageProcessor()
int	getLineStride()
int	getNChannels() Returns the number of color channels in the image.
int	getPixelCount()

int	getWidth() Returns the width of this image in pixels.
boolean	isEmpty()
boolean	isGray()
boolean	isGray16()
boolean	isGray8()
boolean	isInvertedLut() Returns true if this image uses an inverting LUT that displays zero as white and 255 as black.
boolean	isRgb()
void	putPixel(int x, int y, int value) Stores the specified value at (x,y).
void	set(int index, int value)
void	set(int x, int y, int value) This is a faster version of putPixel() that does not clip out of range values and does not do bounds checking.
void	setPixels(java.lang.Object pixels) Sets a new pixel array for the image.

Method Detail

get

public int get(int x,
               int y)

Description copied from interface: SLImage

This is a faster version of getPixel() that does not do bounds checking.

Specified by:

get in interface SLImage

get

public int get(int index)

Specified by:

get in interface SLImage

getHeight

public int getHeight()

Description copied from interface: SLImage

Returns the height of this image in pixels.

Specified by:

getHeight in interface SLImage

getNChannels

public int getNChannels()

Description copied from interface: SLImage

Returns the number of color channels in the image. The color channels can be accessed by toFloat(channelNumber, fp) and written by setPixels(channelNumber, fp).

Specified by:

getNChannels in interface SLImage

Returns:

1 for grayscale images, 3 for RGB images

getPixelCount

public int getPixelCount()

Specified by:

getPixelCount in interface SLImage

getPixels

public java.lang.Object getPixels()

Description copied from interface: SLImage

Returns a reference to this image's pixel array. The array type (byte[], short[], float[] or int[]) varies depending on the image type.

Specified by:

getPixels in interface SLImage

getRoi

public java.awt.Rectangle getRoi()

Specified by:

getRoi in interface SLImage

getWidth

public int getWidth()

Description copied from interface: SLImage

Returns the width of this image in pixels.

Specified by:

getWidth in interface SLImage

isInvertedLut

public boolean isInvertedLut()

Description copied from interface: SLImage

Returns true if this image uses an inverting LUT that displays zero as white and 255 as black.

Specified by:

isInvertedLut in interface SLImage

putPixel

public void putPixel(int x,
                     int y,
                     int value)

Description copied from interface: SLImage

Stores the specified value at (x,y). Does nothing if (x,y) is outside the image boundary. For 8-bit and 16-bit images, out of range values are clipped. For RGB images, the argb values are packed in 'value'. For float images, 'value' is expected to be a float converted to an int using Float.floatToIntBits().

Specified by:

putPixel in interface PixelHandler

Specified by:

putPixel in interface SLImage

set

public void set(int x,
                int y,
                int value)

Description copied from interface: SLImage

This is a faster version of putPixel() that does not clip out of range values and does not do bounds checking.

Specified by:

set in interface SLImage

set

public void set(int index,
                int value)

Specified by:

set in interface SLImage

setPixels

public void setPixels(java.lang.Object pixels)

Description copied from interface: SLImage

Sets a new pixel array for the image. The length of the array must be equal to width*height. Use setSnapshotPixels(null) to clear the snapshot buffer.

Specified by:

setPixels in interface SLImage

setRoi

public void setRoi(java.awt.Rectangle roi)

Specified by:

setRoi in interface SLImage

setRoi

public void setRoi(int x,
