CTAN update: xcolor 2.01

Date: March 15, 2005 11:18:32 PM CET
On Tue, 15 Mar 2005 Uwe Kern submitted version 2.01 of his xcolor package to CTAN. Location on CTAN: macros/latex/contrib/xcolor/ Summary description: Driver-independent color extensions for LaTeX and pdfLaTeX License type: lppl Announcement text:
2005/03/15 v2.01 * New features: - `prologue' option for comprehensive `named' color support in conjunction with `dvips': on-the-fly generation of PostScript prologue files with all color definitions, ready for dvips inclusion and/or post-processing with device-specific parameters (e.g., spot colors); - dvips prologue file xcolor.pro to support additional `named' colors; - \colorlet may now also be used to create named colors from arbitrary color expressions; - enhanced color definition syntax to allow for target-model specific color parameters, e.g. \definecolor{red}{rgb/cmyk}{1,0,0/0,1,1,0}, facilitating the usage of tailor-made colors both for displays and printers; - `deferred definition' of colors: \preparecolor and \definecolors enable decoupling of color specification and control sequence generation, especially useful (= memory saving) for large lists of colors, of which only a few names are actually used; - `dvipsnames*' and `svgnames*' options to support deferred definition. * Changes: - higher accuracy: most complement calculations are now exact for all 5-digit decimals; - \rangeRGB and similar variables may now be changed at any point in a document; - \aftergroupdef now performs only a first-level expansion of its code argument; - \XCfileversion and similar internal constants removed from .sty and .def files; - improved memory management (reduced generation of `multiletter control sequences' by \@ifundefined tests); - several internal macros improved and/or renamed. * Bugfixes: - \XC at getcolor could cause unwanted spaces when \psset was used inside |pspicture| environments (`pstricks'); - arithmetic overflow could happen when too many decimal digits were used within color parameters, e.g. as a result of `fp' calculations.
Thanks for the update. For the CTAN Team Rainer Schöpf

xcolor – Driver-independent color extensions for and pdf

The package starts from the basic facilities of the color package, and provides easy driver-independent access to several kinds of color tints, shades, tones, and mixes of arbitrary colors. It allows a user to select a document-wide target color model and offers complete tools for conversion between eight color models. Additionally, there is a command for alternating row colors plus repeated non-aligned material (like horizontal lines) in tables. Colors can be mixed like \color{red!30!green!40!blue}.
