image mosaic menu
You can move the tiles around by clicking on them with button 1, dragging them around, and then clicking again. You can change a tile's size by clicking on it with button 2 and then clicking again when you like the size. You can remove a tile by clicking on it with button 3.
The system will do automatic alignment of the tiles if you enter a non-zero value in the Fixup tolerance menu field. If you enter 100, for example, then each time you move or rescale a tile, the system checks whether any of its corners are within 100 pixels of the corner of any other tile. If a corner matches closely enough, the system moves the tile into alignment, or changes its size to make it line up (if resizing is what you were doing).
You can force spacing between tiles both vertically and horizontally by entering distances in pixels in the Horizontal spacing and Vertical spacing menu fields.
When you are satisfied with the layout of your mosaic, enter a name for the mosaic image in the Mosaic image menu field, and click on SAVE MOSAIC IMAGE. The system will create the large image and paste all the smaller images into it, in the order that you added them.
