Effortlessly convert latitude/longitude coordinates into a graphical heatmap
of the geographical region relative the number of points outlined.
This is primarily a library for reading portable bitmap (PBM),
portable graymap (PGM), and portable pixmap (PPM) files. These image
formats are only the barest step up from raw data, and have a very
simple format which is the key to be "portable". Writing out images in
these formats is very easy.
This Perl extension aims to cut down the size of PNGs. Users pass a PNG to
various functions (though only one presently exists -
Image::Pngslimmer::discard_noncritical($blob)) and a slimmer version is
returned. Image::Pngslimmer is designed for use where PNGs are being
generated on the fly and where size matters - eg for J2ME use. There are
other options - probably better ones - for handling static PNGs.
and more image types.
Image::Imlib2 is a Perl port of Imlib2, a graphics library
that does image file loading and saving as well as manipulation,
arbitrary polygon support, etc. It does ALL of these operations
FAST. It allows you to create colour images using a large number
of graphics primitives, and output the images in a range of formats.
This Perl extension allows you to extract meta information from
various types of image files. It currently supports JPEG, GIF, PNG
and more image types.
Very simple and very fast (about 30 times faster than Image::ExifTool) EXIF
extractor, based on libexif.
Image::ObjectDetect is a simple module to detect objects
from picture using opencv.
This module implements several resizing algorithms with a focus on low
overhead, speed and minimal features. Algorithms available are:
GD's copyResampled (floating-point)
GD's copyResampled fixed-point (useful on embedded devices/NAS devices)
GraphicsMagick's assortment of resize filters (floating-point)
GraphicsMagick's Triangle filter in fixed-point
Supported image formats include JPEG, GIF, PNG, and BMP for input, and
JPEG and PNG for output.
This module provides access to most of the OpenGL 1.0, 1.1, and 1.2 APIs.
Some amount of GLU is supported (I'm not quite sure what version it works
out to), and GLUT should be completely supported up to API version 3. A
small portion of GLX and X11 is supported, as an alternative to GLUT.
This uses the Imager to find the average gray value
for a image.
