Method Detail

hashCode

int hashCode()

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.

Overrides:

hashCode in class Object

getPixelformat

PixelFormat getPixelformat()

Returns the PixelFormat.

getSize

DimensionImmutable getSize()

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

getStride

int getStride()

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

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

isGLOriented

boolean isGLOriented()

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.

getPixels

ByteBuffer getPixels()

Returns the pixels.

toString

String toString()

Overrides:

toString in class Object
