  • Plot enhancements, thanks to Michael Schmid:
    • Plots saved as tiff or zip include the data, so the plot range can be modified (zooming, etc.) and the data can be listed after loading the plot from a file.
    • Changing the axis or label font size of a plot keeps the image size constant and modifies the plot frame size (previously, the plot frame size was constant).

    • Added Plot.getFrameBounds(x, y, width, height) macro function.
    • The default font for plots is now Arial, not Helvetica (Arial is available on more platforms).
    • When opening a plot on a computer where a given font is not available, try to replace fonts by similar ones. This should make the appearance on different platforms more similar.

  • Thanks to Michael Schmid, the AVI Reader tries to recover data from truncated files.
  • Thanks to Jerome Mutterer, added the setOption("SaveBatchOutput",false) macro function, which can be used in Process>Batch>Virtual Stack macros to prevent slices from being written to the output virtual stack.

  • Added a "Don't set Mac menu bar" option to the Edit>Option>Misc dialog. When this option is set, ImageJ does not set the ImageJ menu bar when image windows are activated. This may prevent ImageJ from becoming unresponsive due to setMenuBar() becoming slower and slower over time. To recover the menu bar, click on the "ImageJ" window or press return, the shortcut for the Window>Main Window command.
  • When running Java 8 on OS X, the "Don't set Mac menu bar" option in Edit>Option>Misc is automatically set when it the setMenuBar() method takes more than two seconds.
