Nip2 spreadsheet-like graphical image manipulation tool front end to the VIPS package.

Nip2 is a graphical front end to the VIPS package.

VIPS is an image processing system designed with efficiency in mind. It is good with large images (images larger than the amount of RAM in your machine), and for working with colour. It can perform many image manipulation tasks much faster than other packages such as ImageMagick and the GIMP and includes some special features such as creating single "mosaic" images from multiple parts.

VIPS consists of two main components: an image processing library with some command-line tools and a spreadsheet-like graphical user interface. This package supplies the graphical interface.

With nip2, rather than directly editing images, you build relationships between objects in a spreadsheet-like fashion. When you make a change somewhere, nip2 recalculates the objects affected by that change. Since it is demand-driven this update is very fast, even for very, very large images. nip2 is very good at creating pipelines of image manipulation operations. It is not very good for image editing tasks like touching up photographs. For that, a tool like the GIMP should be used instead.

VIPS is a free image processing system. It is good with large images (images larger than the amount of RAM you have available), with many CPUs (see Benchmarks for examples of SMP scaling, VIPS is also part of the PARSEC suite), for working with colour and for general research & development.

Compared to most image processing libraries, VIPS needs little RAM and runs quickly, especially on machines with more than one CPU. See the Speed and Memory Use page for a simple benchmark. We have a How it works page with a brief technical explanation of how VIPS calculates pixels.

It comes in two main parts: libvips is the image-processing library and nip2 is the graphical user-interface. The GUI aims to be about half-way between Photoshop and Excel. It is very bad at retouching photographs, but very handy for the many other imaging tasks that programs like Photoshop are used for.

Both work on Unix (with convenient packages for most popular distributions, see links), Windows (NT, 2k, XP, Vista tested) and Macintosh (OS 10.2 and later). The VIPS library is licensed under the LGPL and and the user-interfaces are licensed under the GPL. See http://www.gnu.org.
