Interface GImageGray

All Known Implementing Classes:

FactoryGImageGray.Border_F32, FactoryGImageGray.Border_F64, FactoryGImageGray.Border_I32, FactoryGImageGray.GSingle_F32, FactoryGImageGray.GSingle_F64, FactoryGImageGray.GSingle_I64, FactoryGImageGray.GSingle_S16, FactoryGImageGray.GSingle_S32, FactoryGImageGray.GSingle_S8, FactoryGImageGray.GSingle_U16, FactoryGImageGray.GSingle_U8, FactoryGImageGray.GSingleBase, FactoryGImageGray.GSingleBaseInt, FactoryGImageGray.GSingleBorder, GImageGrayDistorted

public interface GImageGray

Generalized interface for single banded images. Setters and getters which use Number will be much slower than direct access, about 12x. Setts and getters which use index have a negligible difference to about 25% performance hit depending if the data types need to be converted or not.

Method Detail

wrap

void wrap(ImageGray image)

getWidth

int getWidth()

getHeight

int getHeight()

isFloatingPoint

boolean isFloatingPoint()

get

java.lang.Number get(int x,
                     int y)

set

void set(int x,
         int y,
         java.lang.Number num)

Set's pixel value using number. If native type of 'num' and image are the same then there is no loss in precision.

Parameters:

x - pixel coordinate x-value

y - pixel coordinate y-value

num - Value of the pixel

unsafe_getD

double unsafe_getD(int x,
                   int y)

get which returns a double, has no bounds checking. Still slow, but faster than the super generic get. Also doesn't create memory on each get

unsafe_getF

float unsafe_getF(int x,
                  int y)

set

void set(int index,
         float value)

Sets pixel based on pixel value in data array

getF

float getF(int index)

getImage

ImageGray getImage()

getImageType

java.lang.Class getImageType()
