Debian Imaging Image script packages

Auto Adjust Photo is a tiny command-line image manipulation tool for automatic color correction of photos. It tries to make the picture look better. The program does this by analyzing the input image and then sets the most optimal contrast, gamma, color balance and saturation for it.

A simple (yet useful and free) tool for creating client-side image maps, supporting GIF and JPEG images.

The Vector Graphics package of the FreeHEP Java Library enables any Java program to export to a variety of vector graphics formats as well as bitmap image formats. Among the vector formats are Encapsulated PostScript (EPS), Portable Document Format (PDF), Enhanced Meta Format (EMF), Scalable Vector Graphics (SVG), and Flash (SWF), while the image formats include GIF, PNG, JPG and PPM.

This package contains the FreeHEP GraphicsIO Base Library.

pngquant es una herramienta de conversión para la consola que cuantifica y comprime las imágenes PNG de color verdadero, especialmente con un canal alfa completo, a una paleta RGBA de 8 bits (o menor). Estas imágenes normalmente son entre dos y cuatro veces más pequeñas que las versiones completas de 32 bits, y la transparencia parcial se mantiene bastante bien. Esto hace que pngquant sea útil especialmente para los sitios web y para el desarrollo para PlayStation 2, dónde los formatos de las texturas están basados en paletas RGBA (incluso sin comprimir en PNG). Esta es la misma técnica usada para muchas de las imágenes de la página de los PNG transparentes (http://www.ligpng.org/pub/png/pngs-img.html), y los resultados normalmente son indistinguibles del original, imágenes en PNG de color verdadero.

Los optimizadores (como pngcrush u optipng) sólo mejoran la compresión, normalmente sin pérdidas, mientras que pngquant cuantifica los colores a 256 (o menos) en distintas combinaciones de RGBA, por lo que tiene pérdidas.

GraphicsMagick provides a set of command-line applications to manipulate image files. It is a fork of the ImageMagick project and therefore offers a similar set of features, but puts a larger emphasis on stability.

The tools support a large variety of image formats from the widely used jpeg, tiff, bmp or xpm to special-purpose formats such as fits or image formats found on some photo CDs. They can convert between formats, concatenate several images into one, annotate and distort them, create thumbnails or manipulate the colormap. While all features are available from the command-line, the package also includes an image viewer that allows interactive manipulation.

Note that unlike ImageMagick, the GraphicsMagick tools are accessed through a single executable called 'gm'. Therefore, GraphicsMagick and ImageMagick can be used in parallel. Install package graphicsmagick-imagemagick-compat to obtain a set of several executables that is compatible to ImageMagick's interface.

It includes algorithms implemented in C++ for speed while operating in numpy arrays.
