Returns true if all components are of same bit-size, e.g. RGBA8888, otherwise false, e.g. RGBA5551

isInterleaved

boolean isInterleaved()

Returns true if all components are packed, i.e. interleaved, e.g. RGBA8888, otherwise false.

componentCount

int componentCount()

Number of components per pixel, e.g. 3 for RGBx8888.

bitsPerPixel

int bitsPerPixel()

Number of bits per pixel, e.g. 24 bits for RGBx8888.

bitStride

int bitStride()

Bit distance between pixels.

For packed pixels e.g. 32 bits for RGBx8888.

bytesPerPixel

int bytesPerPixel()
