Hotkeys

The following hotkeys are enabled when EMScaleBarTools is selected as a toolset:

[ p ] - Save image as png.

[ s ] - Save image as svg. Requires BioVoxxel Figure Tools.

[ j ] - Save image as jpeg. Prompts for quality/compression factor. Please do not use jpeg in publications.

[ c ] - Copy image to system clipboard.

Will automatically re-scale small images without interpolation (=nearest neighbor interpolation) if "Auto re-scale images" option is enabled in the QuickScaleBar options.

Example: Copying a small 16x8 image from Fiji without and with the "Auto re-scale images" option enabled.
Notice how PowerPoint automatically interpolates the 16x8 image without the re-scaling option.

[ t ] - Switch scale bar and label positions.

Note: The non-default switched position (label above scale bar) requires additional processing steps and is slower than the default position (scale bar above label).
It is faster to use the default position for choosing the size/position/length and only switch the scale bar/label in the final step.

Numpad hotkeys

The numpad gives quick control over the scale-bar appearance.

[*] - Open QuickScaleBar Options menu

[5] - Add/remove scale bar. With ALT key pressed: Switch black/white color.

ALT mode will also switch background colors if present:

[4], [6] - De-/Increase scale-bar length in 1-2-5 series. With ALT key pressed: Specify a custom scale-bar length in measurement units.

The upper limit is given by the image width. The lower limit is given by length = 1 unit.

[2], [8] - De-/Increase scale-bar size via scaling factor. With ALT key pressed: Specify the scaling factor.

[1], [3], [7], [9] - Move scale bar to [1] lower left, [3] lower right, [7] upper left, [9] upper right (i.e., the four corners of the numpad).

[0] - Reset scale bar. Reset to lower right corner. Set scaling factor to 1.
