This package provides an easy and simple way to read, write and
display bitmap images stored in the PNG format. It can read and
write both files and in-memory raw vectors.
Provides bindings to Frank Warmerdam's Geospatial Data Abstraction
Library (GDAL) (>= 1.6.3) and access to projection/transformation
operations from the PROJ.4 library. The GDAL and PROJ.4 libraries
are external to the package, and, when installing the package from
source, must be correctly installed first. Both GDAL raster and OGR
vector map data can be imported into R, and GDAL raster data and
OGR vector data exported. Use is made of classes defined in the sp
package.
GraphicsMagick is the swiss army knife of image processing. Comprised of 267K
physical lines (according to David A. Wheeler's SLOCCount) of source code in the
base package (or 1,225K including 3rd party libraries) it provides a robust and
efficient collection of tools and libraries which support reading, writing, and
manipulating an image in over 88 major formats including important formats like
DPX, GIF, JPEG, JPEG-2000, PNG, PDF, PNM, and TIFF.
GraphicsMagick supports huge images and has been tested with gigapixel-size
images. GraphicsMagick can create new images on the fly, making it suitable for
building dynamic Web applications. GraphicsMagick may be used to resize, rotate,
sharpen, color reduce, or add special effects to an image and save the result in
the same or different image format. Image processing operations are available
from the command line, as well as through C, C++, Lua, Perl, PHP, Python, Tcl,
Ruby, Windows .NET, or Windows COM programming interfaces. With some
modification, language extensions for ImageMagick may be used.
HERMES, named after the messenger of the gods, is a library whose
only purpose is to convert graphic data from one pixel format to another in
the fastest possible way.
HERMES will also do surface clearing. And it will do it FAST (even with
x86 and MMX routines if you're on those platforms).
IPA stands for Image Processing Algorithms and represents the library of
image processing operators and functions. IPA is based on the Prima toolkit,
which in turn is a perl-based graphic library. IPA is designed for solving
image analysis and object recognition tasks with perl.
