The poster plug-in

The poster plug-in is a Gimp plug-in that combines image layers by attaching them in rows and columns. This is useful especially for films.

The plug-in attaches the layers of a RGB or grayscale image row by row from the left to the right. The frames are separated by lines of selectable width in the current foreground color. If the row/column matrix is too small for all layers, the last layers are skipped. If the row/column matrix is too huge for the layers, additional slots are filled with the current background color.

Now, how does this look like???

Lets take the well-known high-speed film of an oscillating cavitation bubble... For a better visibility we choose a red foreground and a blue background color and select "< Image >/Filters/Animation/Poster" afterwards.
