The framebuffer organization may be chunky (packed pixel) or planar.

As this illustrates, packed pixel organization can be directly contrasted with planar organization.

In packed pixel or chunky framebuffer organization, the bits defining each pixel are grouped together.

And more densely packed pixels on a sensor chip means more heat, which can introduce speckles into low-light shots.

Planar graphics are now also obsolete for general purpose computing, since modern graphics hardware has enough memory bandwidth to used packed pixels.

Linda also decompresses two new packed pixels (PACKLUT,PACKHY) on the fly.

You're spared the hassle of reformatting tiny type in the documents that people send you - a frequent occurrence in this era of flat-screen monitors (whose tightly packed pixels tend to shrink text).
