HDR Tools is a set of command-line tools for creating and manipulating High
Dynamic Range (HDR) images. It consists of six programs: hdr_create,
hdr_fix_ca, hdr_denoise, hdr_squish, hdr_adjust, and hdr_convert.
Together, they can convert a set of bracketed photographs to HDR image (in
EXR format), fix chromatic aberrations and CCD noise, perform tone mapping
and some simple color manipulations, apply gamma correction and optionally
adjust the exposure, crop, and finally convert the result into a "normal"
image (a JPG, for example).
hiptext is command line tool for rendering images and videos inside terminals.
hsetroot is a tool which allows you to compose wallpapers ("root pixmaps")
for X11. It has a lot of options like rendering gradients, solids, images
but it also allows you to perform manipulations on those things, or chain
them together. You could use one standard background image for instance,
and using tint to make it fit your current theme. And yes, of course it is
compatible with semi-translucent applications like aterm and xchat.
At this time, hsetroot can render: gradients (multi-color with variable
distance), solids (rectangles) and images (centered, tiled, fullscreen, or
maximum aspect). It supports the following manipulations: tinting
(overlaying a color mask), blurring, sharpening, flipping (horizontally,
diagonally, vertically) it also allows you to adjust brightness, contrast
and gamma-level. hsetroot also supports alpha-channels when rendering
things.
Displays an image in a 256-color enabled terminal with UTF-8 locale, such as
gnome-terminal, konsole, uxterm or rxvt-unicode (urxvt).
ICC Examin is a small utility (Unix name: iccexamin) for the purpose
of watching the internals of ICC profiles, measurement data (CGATS),
colour samples (named colour profiles), gamut visualisations (vrml),
video card gamma tables (Xorg/XFree86/osX).
The IccXML project acts as an extension of SampleICC's IccProfLib
that provides additional I/O capabilities for reading and writing
the ICC profile contents as XML files. Command line tools and an
XML schema are provided.
icon-slicer is a utility for generating icon themes and libXcursor cursor
themes.
The inputs to icon-slicer are conceptually:
A) a set of multi-layer images, one for each size
B) a XML theme description file
Each image contains all the cursors arranged in a grid; for cursors the
layers are:
- a layer with a dot for the hotspot of each cursor
- the main image or first animation frame for multi-frame animated cursors
- the second animation frame for multi-frame animated cursors
For icons, the layers are:
- a layer with the images
- an optional layer with attachment points for emblems
- an optional layer with boxes for embedding text into icons
In practice, since loading of multilayer images is not supported by standard
image libraries, each layer is input as a separate image file.
Icontact joins multiple image files together to create a single image.
It supports many different images formats and is extremely
customisable.
