Added the IBCSO scheme for
Southern Ocean bathymetry.
05/04/2013
Added the lookup tables from the ImageJ
astronomical visualisation program.
25/02/2013
Added the colour maps included with the
Fractint fractal generation
program.
19/02/2013
Added two wikipedia cartographic schemes: subtle elevation for
Pakistan
and a topographic/bathymetric scheme for
Colombia.
01/10/2012
Experimental tagging removed.
17/08/2012
All SVG files now include a preview.
New metadata files DESC.xml are included in the
zipfiles, this information can be used by software (in particular,
QGIS) to aid the browsing a downloaded copy of the archive.
All COPYING.xml files now include a distribute
field, used by 3rd party distributors of subpackages. Currently
only QGIS uses this field, other projects are welcome to use
the same mechanism.
08/08/2012
Added an experimental tagging feature. The tags will
be used to improve existing selections (views) and
generate new ones.
04/07/2012
Added new cartographic from wikipedia users
TUBS and
Lilleskut.
Added new wikipedia schemes, wkp/ice
for ice-thickness, and another for the elevation and bathymetry of the
Celtic Sea.
20/11/2011
Added pd/astro, a set of gradients
taken from astronomical images, by Piecrust Design.
16/11/2011
Completed the transition to full alpha channel (transparency,
opacity) support. Gradients which have an alpha channel now
have an extra field in their description stating the colour
which replaces alpha in formats which do not support it (cpt,
soa, gpf). The form is αB for black,
αW for white and so on.
28/10/2011
All gradients now available in the SOA/DS9 colour map (soa)
format.
16/10/2011
Updated all of the
COLOURLovers palettes and their
continuous versions using
the variable widths now available in the COLOURLovers
web API.
Due to a typo in a build script all of the version
1.57 zip files contained only cpt files, now fixed.
12/01/2010
Added copyright information for all files. The information
applies to all of the gradients in a directory, and so some
directory reorganisation was required for
J.J. Green's gradients and the
Wikipedia schemes.
All gradients now also available in version 3 of the grd format
(supported by PaintShop Pro and Photoshop) converted with an
experimental code; these have only been lightly tested, please
report any problems.
29/08/2006
Added 4 sets of subtle gradients by Meghan
Miller of Crumblingwalls.
28/08/2006
All POV-Ray headers regenerated with version 1.25 of cptutils, the
colour-map name is now coerced to contain only alphanumerics
and underscores (fixing some POV-Ray parse errors).
27/06/2006
More from Michele Albert with gradients inspired by
icecream and a striking
selection of red-greys.
Sorted out the mime-types, I think, having set all gradients to be
of type "text/other". Text, so that line-ending conversion should
be done for people on weird platforms. Other, as I don’t want to view
a gradient as text (in the way you would with a README.txt), and on
firefox "text/other" forces a download dialogue. Nice. If you know
a better type please let me know.
24/08/2005
On the move; cpt-city now has a new home. Many thanks to the
University of Sheffield for hosting the site for the last 2
years.
09/07/2005
Download stats now exclude multiple downloads of a file to the
same IP.
26/06/2005
New versions of the cpt and ggr files translated from the Open Clipart
Library SVG gradients. The ggr files now have a correct alpha channel.
04/06/2005
All svg gradients updated following some enhancements to the cpt to svg
translation code.
31/05/2005
Gradients are now also available in the svg format using an experimental
conversion from cpt. A few cpt files (those with HSV colour model, and
those with hatchures) do not yet translate.
23/04/2005
Gradients are now also available in the ggr (GIMP gradient) format.
Added new palette
pseudogrey with 1785 levels of near grey,
from an idea by Rich Franzen.
08/02/2005
Added the gradients by
Ingerlise, again converted from the
PaintShop Pro gradient format.
28/01/2005
Added a fine set of subtle gradients by
onecoldcanadian. These were converted
from the PaintShop Pro gradient format with an experimental
code; they may be subject to change.
28/12/2004
Modified the way that the png files are generated, hatchures are
now much clearer.
28/11/2004
Added new palette
gebco-shelf
for continental shelf bathymetry. This is the GMT gebco palette
but with a maximal depth of 700m rather than 7000m.
Corrected definition list errors in news, and gave it a bit of
a tidy up.
26/08/2004
The 6,000th cpt download. Everybody wants to live in cpt-city, and
who can blame them?
26/08/2004
The site notes are now generated with the perl template
toolkit: this is for future extension and should not affect
the site’s appearance.
26/08/2004
Added some internal links.
22/08/2004
A superficial reorganisation of the front-page
dividing peripheral material into notes, stats and
views categories, the directory structure of the site
being change to reflect this.
18/08/2004
Links to gimpcpt redirected to cptutils.
10/08/2004
Fixed a few broken links.
18/06/2004
Neota has kindly contributed his most recent
colour work, a panorama of 136 continuous toning gradients for pixel art.
This really is a fabulous collection.
