Renumber images

Renumber images command renumbers all or a given range of images in the tie points file. It adds a constant number to the existing image numbers or converts 32-bit image numbers into 64-bit numbers.

TerraPhoto requires a unique number for images in the active image list which is derived from the image file names. These image numbers are stored in the tie point file. If it is necessary to rename the image files, the numbers in the image list change. Therefore, it might be necessary to change the image numbers in the tie point file as well in order to ensure that tie points still work for the renamed images.

The update of image numbers is also required if an old tie point file with image numbers stored as 32-bit values is used for a new image list file with image numbers stored as 64-bit values (TerraPhoto version 010.014 or later).

To renumber images:

1. Select Renumber images command from the File pulldown menu.

This opens the Renumber tie point images dialog:

renumber_tie_point_images

2. Define settings and click OK.

The new numbering is applied for the tie points. An information dialog shows the amount of images that have been renumbered.

3. Save the tie points using Save or Save As commands from the File pulldown menu in order to save the tie points with renumbered images into a file.
