Interlacing (bitmaps)

Interlacing (also known as interleaving) is a method of encoding a bitmap image such that a person who has partially received it sees a degraded copy of the entire image. When communicating over a slow communications link, this is often preferable to seeing a perfectly clear copy of one part of the image, as it helps the viewer decide more quickly whether to abort or continue the transmission.

Interlacing is supported by the following formats, where it is optional:

  • GIF interlacing stores the lines in the order 0, 8, 16, ...(8n), 4, 12, ...(8n+4), 2, 6, 10, 14, ...(4n+2), 1, 3, 5, 7, 9, ...(2n+1).
  • PNG uses the Adam7 algorithm, which interlaces in both the vertical and horizontal direction.
  • TGA uses two optional interlacing algorithms, two-way: 0, 2, 4, ...(2n), 1, 3, ...(2n+1) and four-way: 0, 4, 8, ...(4n), 1, 5, ...(4n+1), 2, 6, ...(4n+2), 3, 7, ...(4n+3).
  • JPEG, JPEG 2000, and JPEG XR (actually using a frequency decomposition hierarchy rather than interlacing of pixel values)
  • PGF (also using a frequency decomposition)

Interlacing is a form of incremental decoding, because the image can be loaded incrementally. Another form of incremental decoding is progressive scan. In progressive scan the loaded image is decoded line for line, so instead of becoming incrementally clearer it becomes incrementally larger. The main difference between the interlace concept in bitmaps and in video is that even progressive bitmaps can be loaded over multiple frames.

For example: Interlaced GIF is a GIF image that seems to arrive on your display like an image coming through a slowly opening Venetian blind. A fuzzy outline of an image is gradually replaced by seven successive waves of bit streams that fill in the missing lines until the image arrives at its full resolution.

Interlaced graphics were once widely used in web design and before that in the distribution of graphics files over bulletin board systems and other low-speed communications methods. The practice is much less common today, as common broadband internet connections allow most images to be downloaded to the user's screen nearly instantaneously, and interlacing is usually an inefficient method of encoding images.

Interlacing has been criticized because it may not be clear to viewers when the image has finished rendering, unlike non-interlaced rendering, where progress is apparent (remaining data appears as blank).

Usage examples of "interlacing".

And lower down the great forest trees arch over it, and the sunbeams trickle through them, and dance in many a quiet pool, turning the far-down sands to gold, brightening majestic tree-ferns, and shining on the fragile polypodium tamariscinum which clings tremblingly to the branches of the graceful waringhan, on a beautiful lygodium which adorns the uncouth trunk of an artocarpus, on glossy ginger-worts and trailing yams, on climbers and epiphytes, and on gigantic lianas which, climbing to the tops of the tallest trees, descend in vast festoons, many of them with orange and scarlet flowers and fruitage, passing from tree to tree, and interlacing the forest with a living network, while selaginellas and lindsayas, and film ferns, and trichomanes radicans drape the rocks in feathery green, along with mosses scarcely distinguishable from ferns.

Hark ye, lad--fleet interlacings of the limbs-- lithe swayings--coyings--flutterings!

The whole front of it was covered by a large scarlet bignonia and a native multiflora rose, which, entwisting and interlacing, left scarce a vestige of the rough logs to be seen.

There seemed, however, a steady attempt to isolate antagonists, to cut them off from their fellows and bear them down, causing a perpetual sailing back and interlacing of these shoaling bulks.

The narrow valley, with its steep and close adjoining sides draperied with vines, and arched overhead with a fret-work of interlacing boughs, nearly hidden from view by masses of leafy verdure, seemed from where I stood like an immense arbour disclosing its vista to the eye, whilst as I advanced it insensibly widened into the loveliest vale eye ever beheld.

Up either column ran the same intricate interlacing patterns as on all other columns in that place, patterns he had seen in weaving or pottery all his life, now graved deep in polished stone.

On a round hill between spires of rock flourished the wild garden of Saara: a meadow of heavy grass, cut by interlacing streams, dotted with the early blue aster, and wound about with the sprawling late red rose.

Hark ye, lad — fleet interlacings of the limbs — lithe swayings — coyings — flutterings!

It was on the coast of Tehama, for there not only did this display of zoöphytes flourish beneath the level of the sea, but they also formed picturesque interlacings which unfolded themselves about sixty feet above the surface, more capricious but less highly colored than those whose freshness was kept up by the vital power of the waters.
