[feranick@…]

A new version of gwyddion (2.26) has been released upstream with several enhancements:

Application

Translations updated: Czech, French, Italian, Russian, Spanish. Keyboard shortucts can be modified by pointing to the menu item and pressing the new shortcut (after enabling this in the Edit menu).

Libraries

libgwydgets: Graph data can be exported to ASCII in a locale-independent way. libgwydgets: Graph window properly disconnects signals from the graph model when destroyed. libgwydgets: Labels on 3D view axes are rotated with the axes. libgwydgets: 3D view supports ‘overlay’ mode with secondary data or mask used for false colour mapping. libgwydgets: 3D view can show false colour scale. libgwydgets: Vertical graph measurement mode was added. libgwyapp: Possible crash due to wrong freeing of GBookmarkFile was fixed. libgwyapp: File chooser can plane- and/or row-level previewed data. libgwyapp: Critical warning/crash in file merging was fixed. libgwyapp: Data browser updates the thumbnail also when the mask changes. libgwyprocess: Kaiser 2.5 FFT window was fixed to avoid returning NaNs at certain transform sizes (due to rounding errors). libgwyddion: New functions for case-insensitive string hashing. libgwyprocess: New function for asymmetrical outlier marking. libgwyprocess: Bug affecting calculation surface areas and volumes of grains on the lower edge of a non-square image was fixed.

Modules

Code V INT (new): Imports Code V INT grid interferograms. Zeiss (new): Imports Carl Zeiss SEM scans (TIFF). Hitachi SEM (new): Import Hitachi S-3700 and S-4800 SEM data. ISO28600 (new): Imports and exports ISO 28600:2011 SPM data transfer format. Alicona (new): Imports Alicona Imaging Al3D files. WITec ASCII (new): Imports WITec ASCII export files. RHK SM4: Support for spectra reading was added (as graphs). 1D FFT filter: Correct X-axis units of Fourier modulus are displayed. Level Grains: The sign of extracted background was corrected. LEXT: Crashing on systems lacking memrchr(), namely MS Windows, was fixed. Graph export ASCII: Can export floating point numbers in POSIX format. Pixmap: Scalebar are drawn (with the default length) even when the module is used non-interactively. Pixmap: Critical warning/crash ‘assertion text!=NULL failed’ was fixed. Nanoscope: Import of files with non-1:1 pixels was improved. Dumb: Builds on big-endian architectures. SDFile: Letter case of header fields is ignored. SDFile: Extra fields after the data are made available in metadata. WIP: Swapped x and y axes were corrected. Statistical functions tool: Height distribution can use masking. Roughness tool: The resulting curves are no longer automatically levelled. Unisoku: Import of files containing NUL characters in the header was fixed. Pattern synthesis: Real values of parameters are displayed immediately after a pattern type switch. Pygwy: Values are stored to GwyContainer as fundamental GObject types so they can be actually serialised. Pygwy: Load and save module functions can take an optional run mode argument.

Other

Compatibility with gcc 4.6 and autoconf 2.68 was improved. The thumbnailer permits specifying the channel used to create the thumbnail (if run manually). Drag'n'drop should work on Win32 again. Bzip2-compressed source code tarballs were replaced with xz-compressed.
