Saving to the buffer does not involve selecting a destination directory or specifying a file name. All the images processed in, e.g., the View module can be saved to the Buffer and then loaded in a different module with Load from Buffer option. Additionally, a new module can be opened during the loading from buffer procedure as shown below:
When Load from Buffer is activated a dialog window as above appers. In the uppermost part the images saved to buffer are displayed. More then one image can be selected with CTRL + click. On the right side of the image preview display, an Open with button allows choosing the module where the selected images are going to be loaded. Finally, click Open to load the images.
