Pad Image Names

The tool allows to pad the numbers of a series of images with leading zeros. If you have for example a time series with the images img1.tif, img5.tif, img10.tif and img15.tif you can pad the numbers to 3 digits which resluts in img001.tif, img005.tif, img010.tif and img015.tif. The advantage of the padded numbering is that the alphanumerical ordering will be the same as the numerical ordering for the numbers and the images will therefore always be treated in the right order.

Getting started

To install the tool, drag the link Pad_Image_Names_Tool.ijm to the ImageJ launcher window. Save it under /plugins/tools in the ImageJ installation and restart ImageJ.

Select the "Pad_Image_Names_Tool" from the >> button of the ImageJ launcher. This will add a button with the label "p" to the current toolset.
