v0.9.3 2018-10-23 Zagreb

  • Add Color.to_srgbi (inverse of Color.v_srgbi). Thanks to Christophe Troestler for the patch.
  • Add missing constraints on Float.{is_nan,equal,compare}. Polymorphic equality was being used. Thanks to Christophe Troestler for the report (#17).
  • Fix bug in Gg.M3.rot2 ?pt:(Some _) (#18).

v0.9.2 2017-01-24 La Forclaz (VS)

  • Add Box{1,2,3}.add_pt. Thanks to Christophe Troestler for the suggestion.
  • V{2,3,4}.norm avoid {under,over}flows. Thanks to Christophe Troestler for the report and guidance.
  • Fix Size.of_w. Thanks to @rand00 for the report and the fix.
  • Safe-string support.
  • Build depend on topkg.
  • Relicense from BSD3 to ISC.

v0.9.1 2015-08-14 Cambridge (UK)

  • Fix Box1.pp and add to toplevel support.
  • Fix broken Box{1,2,3}.subset functions. Thanks to Armaël Guéneau for the report.
  • Change toplevel support scheme, #require "gg" no longer automatically opens Gg and installs printers. You now have to #require "gg.top" for this to happen.

v0.9.0 2014-08-23 Cambridge (UK)

  • Fix toplevel printer installation.
  • Use package builder topkg for distribution.
  • Add Gg.Ba (experimental). Convenience module for linear 1D bigarrays. The library now depends on Bigarrays.
  • Many changes and fixes to the experimental Gg.Raster module.
  • Removed to_string functions, they were not thread safe and we now have Format.asprintf which can be used with the pretty printers.
  • Add an optional argument to M3.rot2 to specify a center for the rotation.
  • Optimize M{2,3,4}.mul on M{2,3,4}.id arguments.
  • Add M4.{move2,rot2,scale2,rigid2}
  • Rename M4.{ortho,persp}, replace ~bottom by ~bot.
  • Add Size1 module for sizes in 1D space.
  • Add Box1 module for 1D axis-aligned boxes (closed intervals).
  • Add Size2.{aspect,of_h,of_w} functions.
  • Add Box2.{bm_pt,ml_pt,mm_pt,mr_pt,tm_pt} for accessing middle points on the sides.
  • Rename Box2.{bottom,top}_{left,right} to Box2.{b,t}{l,r}_pt.
  • Add Box3.{fbl,fbr,ftl,ftr,nbl,nbr,ntl,ntr} corner accessors.
  • Fix a bug in Box3.inset, new size was incorrectly computed.

The following functions were renamed so that each module uses the same name for the same transform. Previously we had e.g. M3.scale and M4.scale3 (3D) and M4.scale (4D) which is confusing and inconvenient when one wants to switch from one matrix to the other.

  • Rename M2.{rot,scale} to M2.{rot2,scale2}.
  • Rename M3.{move,rot,rigid,srigid} to M3.{move2,rot2,rigid2,srigid2}.
  • Rename M3.{rot_{map,axis,zyx},scale} to M3.{rot3_{map,axis,zyx},scale3}.
  • Rename M4.{move,rot_{map,axis,zyx},scale,rigid,rigidq,srigid,srigidq} to M3.{move3,rot3_{map,axis,zyx},scale,rigid3,rigid3q,srigid3,srigid3q}
  • Rename M4.scale to M4.scale4
  • Rename M4.{rot_{map,axis,zyx},to_rot_{axis,zyx} to M4.{rot3_{map,axis,zyx},to_rot3_{axis,zyx}.

v0.8.0 2013-09-24 Lausanne
