What's new in Gwyddion 2.44

Jan 12, 2016
  • Application:
  • Translations updated: Czech, French, Russian.
  • Libraries:
  • libgwyapp: Potential corruption of recent file list by Save As introduced in 2.43 was fixed.
  • libgwydgets: Gwy3DView no longer downsamples data during changes, all operations are done with full-resolution surfaces. Its "reduced-size" property was deprecated and it has no effect.
  • libgwydgets: Gwy3DView light source distance from the surface no longer scales with Value scale, improving views with small Value scale a lot.
  • libgwyddion: gwy_debug() adds timestamp to the messages (where available).
  • libprocess: Rare incorrect memory reallocation in Delaunay triangulation was fixed.
  • libgwyapp: gwy_app_channel_remove_bad_data() now ensures the mask field has the same lateral dimensions and units as the data field.
  • libgwyprocess: Bogus value returned by gwy_data_field_area_get_entropy() with mask exclusion mode was fixed.
  • libgwyprocess: Functions for estimation of the entropy of two-dimensional point cloud, and for entropy-from-histogram-at-scale curves were added.
  • libgwydgets: Graph labels respond to "label-property" changes. The property is also meaningfully updated when user moves the label around.
  • libgwyprocess: An iterative cancellable version of function gwy_triangulation_triangulate() was added.
  • libgwyprocess: Functions for filling area under mask with a value and simple data-average correction using unmasked data were added.
  • libgwydgets: GwyGraphModel and GwyGraphCurveModel clone() methods were implemented.
  • libgwyprocess: Euclidean distance transform with from_border=FALSE actually work for all cases, previously the border-influenced ares had to be limited.
  • libgwyprocess: New function for simple regularisation of XYZ data to a data field was added.
  • libgwyapp: Data windows hidden and re-shown from the data browser no longer lose the window icon showing a data thumbnail.
  • Modules:
  • Entropy (new): Visualises entropy calculation for distributions of values and slopes.
  • Leica (new): Imports Leica LIF CLSM images.
  • Nano Measuring Machine (new): Imports NMM profile sets and regularises them to raster data.
  • DM3: Support for Digital Micrograph DM4 files was added.
  • Image export: The number of digits in false colour axis ticks can be controlled explicitly. Very small negative values are displayed as ‘0.0’, never the odd ‘-0.0’.
  • Magellan: RGB images are accepted and the channels are averaged upon import.
  • APE file: Crash when loading files with fewer actual data than reported by the channels bit mask was fixed.
  • Limit Range: Setting range from fixed colour mapping range was fixed.
  • NanoScanTech: Loading from raw binary data blocks was implemented.

  • Spectral synthesis: Possible critical message when re-running the function after deleting a channel was fixed.
  • Rawfile: Replacement value for missing data can be given as text for text formats, e.g. ‘BAD’ or ‘NODATA’.
  • Raw XYZ: A bug in point merging was fixed that sometimes caused infinities to appear in the data. Triangulation is remembered and not recomputed when not necessary. A progress bar is shown for the trianguation process and it is possible to cancel it. New interpolation type ‘Average’ was added, which is always fast and produces a result similar to a bit fuzzier ‘Round’ interpolation. Button ‘Reset Ranges’ permits resetting the data ranges to the initial values obtained from the file data ranges. Point density can be plotted as another field.
  • GWYXYZF: The regularisation method was improved to ‘Average’ from Raw XYZ.
  • Nanoscope: Support for 32bit raw data format used since 9.2 was added.

  • GWYXYZF: Incorrect memory freeing, possibly causing leaks or crashes, was fixed.
  • Other:
  • Gwyddion can use either minizip or libzip for opening of ZIP-compressed file formats. The former is used if both are found.
  • Configure checks for gtk-doc at least 1.10, required to build the documentation (older versions were actually insufficient even before).
  • RPM requires rubypick only on RedHat-based distros.
