Wumpus - (W)riter (M)onad (P)ost (S)cript. . Wumpus is a kernel library for generating 2D vector pictures, its salient feature is portability due to no FFI dependencies. It can generate PostScript (EPS) files and SVG files. The generated PostScript code is plain [1] and reasonably efficient as the use of stack operations, i.e @gsave@ and @grestore@, is minimized. . Pictures in Wumpus are made from /paths/ and text /labels/. Paths themselves are made from points. The usual affine transformations (rotations, scaling, translations) can be applied to geometric objects. Unlike PostScript there is no notion of a current point, Wumpus builds pictures in a coordinate-free style. . GENERAL DRAWBACKS... . For actually drawing pictures, diagrams, etc. Wumpus is very low level. There is a supplemantary package @wumpus-basic@ available that helps create certain types of diagram, but even this lacks the higher-level stuff (polygons, arrows etc.) that would make creating general drawings easy. . Some of the design decisions made for wumpus-core are not sophisticated (e.g. how attributes like colour are handled, and how the bounding boxes of text labels are calculated), so Wumpus might be limited compared to other systems. However, the design permits a fairly simple implementation - which is a priority. Text encoding an exception - I\'m not sure how reasonable the design is. The current implementation appears okay for Latin 1 but may be inadequate for other character sets, so I may have to revise it significantly. . WARNING... . The module @Core.BoundingBox@ is likely to be reworked significantly in the future. It has too many functions that do not offer distinct functionality. Some functions were removed in revision 0.17.0 and some more are likely to follow. . The module @Extra.PictureLanguage@ is deprecated. At some point it will be superceded by @wumpus-basic@ but this will not be soon. . . \[1\] Because the output is simple, straight-line PostScript code, it is possible to use GraphicsMagick or a similar tool to convert Wumpus'\s EPS files to many other formats (bitmaps). . Changelog: . 0.19.0 to 0.20.0: . * Removed the modules - Wumpus.Extra.SafeFonts, Wumpus.Extra.SVGColours, Wumpus.Extra.X11Colours - they are now in the package @wumpus-basic@. . * Removed the example FontPic.hs to @wumpus-basic@. . * Renamed two functions in Core.BoundingBox - @trace@ changed to @traceBoundary@; @retrace@ changed to @retraceBoundary@. . * Fixed bug with @picOver@, previously the zorder was wrong and the function was actually working as /picUnder/. . * Added @capHeight@ to FontSize - get the size of an upper case letter without ascenders of descenders. . * Guide updated regarding the new package @wumpus-basic@. . . build-type: Simple stability: unstable cabal-version: >= 1.2 extra-source-files: CHANGES, LICENSE, demo/AffineTest01.hs, demo/AffineTest02.hs, demo/AffineTest03.hs, demo/AffineTest04.hs, demo/AffineTestBase.hs, demo/LabelPic.hs, demo/MultiPic.hs demo/Picture.hs, doc/Guide.pdf, doc-src/Guide.lhs, doc-src/Makefile, doc-src/WorldFrame.hs library hs-source-dirs: src build-depends: base < 5, containers, time >= 1.1.3 && < 1.2, wl-pprint, vector-space, monadLib, xml, algebra < 0.1 exposed-modules: Wumpus.Core, Wumpus.Core.AffineTrans, Wumpus.Core.BoundingBox, Wumpus.Core.Colour, Wumpus.Core.FontSize, Wumpus.Core.Geometry, Wumpus.Core.GraphicsState, Wumpus.Core.OutputPostScript, Wumpus.Core.OutputSVG, Wumpus.Core.Picture, Wumpus.Core.TextEncoder, Wumpus.Core.TextLatin1, Wumpus.Core.VersionNumber, Wumpus.Core.WumpusTypes, Wumpus.Extra.PictureLanguage other-modules: Wumpus.Core.PictureInternal, Wumpus.Core.PostScript, Wumpus.Core.SVG, Wumpus.Core.OneList, Wumpus.Core.TextEncodingInternal, Wumpus.Core.Utils extensions: ghc-options: includes:
