Breaking the Output Bitmap into Overlapping Tiles

A single large bitmap (on the order of several GBytes) may not be as useful as having the same data organized into smaller "bands" or "tiles." In many cases manipulations have to be done on the bitmap data and those computations can be subdivided into regions. Often where regions meet there is a need to do additional processing so that when stitched together the "seam" is invisible. Hence the need for overlapping tiles.

The "SVG" version of GDS_RIP incorporates several customized tiling and overlapping output options.

  • Horizontal Banding
  • Vertical Banding
  • Tiles Phase I
  • Tiles Phase II

Horizontal Banding

With this option the image is divided into bands horizontally as shown. A band defaults to be the entire width of the image unless the user specifies a width.

Vertical Banding

With this option the image is divided into bands running vertically as shown. A band defaults to be the entire height of the image unless the user specifies a height.
