Available: 10 January 2008
This is the first version designed for and tested under Windows Vista (but it also works under XP). It has been produced by a different compiler (the latest available) and thus has inherited some enhancements of modern tools built-in (increased capacity or limits of some functions related to maximum image size).
Note: WinDENDRO 2008a will not read analyses stored in tiff image files made with versions 6.5 and less. Those files can be read only if they are first converted to an earlier version with a previous version of WinDENDRO (such as 2003, 2004, 2005 or 2006).
- You can undo and redo interactive ring and path modifications commands such as moving, reorienting, adding and deleting rings.
- It is now possible to recreate paths which have been deleted (using Path/Delete Active Path or Path/Cancel Analysis).
- Paths can now be continued (prolonged) after they have been closed (terminated).
- The last segment of a path can now be deleted after it has been closed (terminated).
- Brother paths (having a common beginning point such as the centre of a disk) can be added to existing paths (works for single or multi-segments paths).
- Analysed images saved in Tiff files contain more of WinDENDRO’s analysis settings (interactive compression and void areas (Density version), ring features names and interactive markers...).
- You can choose what to do with the analysis when a tiff file previously analysed in WinDENDRO is loaded. WinDENDRO can: 1) load the image without the analysis or 2) load some or all of the analysis settings along with the analysis in the file. The choice of which settings are loaded is done in a new command, Path/Analysis Preferences.
- A batch reanalysis command has been added. Used in conjunction with the preceding feature (selection of which settings are loaded from tiff files) it allows to reanalyse a series of images with different setup parameters (e.g. new calibration, earlywood definition, data file format...) without operator supervision.
- It is now possible to create reference series (master chronologies) from unequal number of ring widths series. Messages are now displayed in more error situations.
- It is possible to create reference data series (master chronologies) by merging existing reference data series (thus creating them with or without analysed images). It also takes into account from how many series they have been averaged from to keep their respective weight.
- The reference data format has been modified (.ref2 format) to hold the information about from how many data series a reference data set come from (so its weight is kept when later averaged with other series).
- The area measurement module is now included in the Density version. It allows to measure the area of regions you outline in the image (such as void, cracked or compression areas).
- When area measurements are done (Density version) with or without paths created, WinDENDRO will write their total area in the Command area. In earlier versions, it was written only if a Log outline analysis had been done.
- The tree (sample) name of files converted to Tucson (decadal) format now have a different digit given by WinDENDRO (as the last character of the name) if the user have turned on Path identification in Path/Identification/Preferences. This allow to have different sample identifications in Tucson's files for multiple radii made on the same sample.
- 10 to 16 bits per pixel grey levels images are saved in 10 to 16 bits (not 8 as before) with or without their analysis.
Modifications to the interface
- The Command Area width is now adjustable.
- Information about the scanner calibration stored in the Scanner.cal file is now visible in Calibration/Method. This comprises its manufacturer, model and serial number. Dual lens scanners are also supported.
- More data about the intensity profile (min, max and average) are displayed in the Command area when density analysis is not active (intensity related data not density data). Also this information is now written with a three digits precision instead of one
- After a click to create a ring, it is highlighted so it can be deleted right away just by clicking again (without having to move the mouse).
- The Channel selection command has been moved from the Image to the Display menu.
- Background light unevenness compensation in the scanning direction can be defined from any vertical or horizontal direction. A rectangle is now drawn around the area used for compensation.
- Background light unevenness compensation in the scanning direction now works with 16 bits per pixels images and works better in 8 bits.
- When you activate Density/Density Analysis and that Light calibration is set to After Image Acquisition (in Density/Light Calibration Parameters), a message indicating to do a light calibration is displayed rather than starting the calibration.
- The graphic of light calibration (in Density/Light Calibration Parameters) now displays in red invalid portion of the curve and will clip it to the graphic boundary.
- Some command names have been simplified (shortened and/or reorganised into hierarchical menus) or their window have been redesigned.
- The WinDENDRO’s welcome (copyright) window displayed at startup fades away after a few seconds.
Bug Fixes / Annoyances Removed
- Alt + click to reorient a ring, did now work for the last ring of a path which had descending paths.
- Earlywood width manually set by the user will remain after modifications to paths.
- The keyboard commands to shift rings (W, Z, Shift+W, Shift+Z) also shifted rings highlighted on inactive paths (a very rare situation since rings are only highlighted on the active path).
- A freeze which occurred sometimes when activating Path/Define Gap Area and zooming the image or scrolling it instead of clicking it right away.
- The double confirmation (Ok or Cancel) after Path/Edit Active Path Identification.
- Ring angle on descending segments was not displayed in the Command Area when the mouse was over a ring.
- Graphic of light calibration will not crash if the same intensity is entered for two consecutive steps.
- Data/Format Preferences. The dot is always used as a decimal separator.
- The 16 bits display range sub-menus items of the Image menu.
- Image/Save Image Selection.
- Light equalization (the method other than in scanning direction).
