A small miscellany of macro code files for ImageJ, for various tasks.

Some are simply demo files.

• Find_All_Pixel_Groups.ijm Finds all groups of connected pixels in a binary image; demonstrates two methods.

• Line_to_Scalebar_Equal_Ticks.jnm Divides a line into N equal parts with N-1 ticks.

• Draw_Spheres_and_Merge_Stacks.ijm Creates two stacks with binary spheres, then overlays them in RGB colour

  

• Point-to-Line Distance Distribution.ijm Draws a scatterplot showing pixel values and distances relative to a line selection.

  

  Output scatter plot, with distance on the horizontal axis and value on the vertical axis (decreasing downward).

  

• Square_Grid_Crop.ijm Crops out squares from a grid that are separated by dark lines using particle analysis.

  Input image of a grid:

  

  Output images from grid:

  

• PixelShuffle2.ijm is a replacement for PixelShuffle.ijm. The original was very slow due to an inefficient shuffling algorithm. The replacement uses the Fisher–Yates shuffle algorithm:
