Constructor Detail

PixelRectangle.GenericPixelRect

public PixelRectangle.GenericPixelRect(PixelFormat pixelformat,
                               DimensionImmutable size,
                               int strideInBytes,
                               boolean isGLOriented,
                               ByteBuffer pixels)
                                throws IllegalArgumentException,
                                       IndexOutOfBoundsException

Parameters:

pixelformat -

size -

strideInBytes - stride in byte-size, i.e. byte count from one line to the next. If not zero, value must be >= width * bytes-per-pixel. If zero, stride is set to width * bytes-per-pixel.

isGLOriented -

pixels -

Throws:

IllegalArgumentException - if strideInBytes is invalid.

IndexOutOfBoundsException - if pixels has insufficient bytes left

PixelRectangle.GenericPixelRect

public PixelRectangle.GenericPixelRect(PixelRectangle src)
                                throws IllegalArgumentException,
                                       IndexOutOfBoundsException

Copy ctor validating src.

Parameters:

src -

Throws:

IllegalArgumentException - if strideInBytes is invalid.

IndexOutOfBoundsException - if pixels has insufficient bytes left

Method Detail

hashCode

public int hashCode()

Description copied from interface: PixelRectangle

Computes a hash code over:

• pixelformat
• size
• stride
• isGLOriented
• pixels

The hashCode shall be computed only once with first call and stored for later retrieval to enhance performance.

Specified by:

hashCode in interface PixelRectangle

Overrides:

hashCode in class Object

getPixelformat

public PixelFormat getPixelformat()

Description copied from interface: PixelRectangle

Returns the PixelFormat.

Specified by:

getPixelformat in interface PixelRectangle

getSize

public DimensionImmutable getSize()

Description copied from interface: PixelRectangle

Returns the size, i.e. width and height.

Specified by:

getSize in interface PixelRectangle

getStride

public int getStride()

Description copied from interface: PixelRectangle

Returns stride in byte-size, i.e. byte count from one line to the next.

Must be >= PixelRectangle.getPixelformat().bytesPerPixel() * PixelRectangle.getSize().getWidth().

Specified by:

getStride in interface PixelRectangle

isGLOriented

public boolean isGLOriented()

Description copied from interface: PixelRectangle

Returns true if the memory is laid out in OpenGL's coordinate system, origin at bottom left. Otherwise returns false, i.e. origin at top left.

Specified by:

isGLOriented in interface PixelRectangle

getPixels

public ByteBuffer getPixels()

Description copied from interface: PixelRectangle

Returns the pixels.

Specified by:

getPixels in interface PixelRectangle

toString

public final String toString()

Specified by:

toString in interface PixelRectangle

Overrides:

toString in class Object
