Trouble report 565

Abnormal termination when moving edge of overlap region after Swing Lens stitch

Versions affected

4.0 - 4.2

Description

This problem only affects panoramas that were stitched with Swing lens or rotational camera selected for the camera type and with images that have more than 8 bits per color channel.  If you selected another camera type or if you used images with 8 bits per color channel (JPG, BMP. 8-bit PNG or 8-bit TIF), you will not encounter this problem.

After stitching with Swing lens or rotational camera selected, editing or moving the right hand edge of an overlap region causes an abnormal termination.

This happens only when:

  1. Automatically blend overlaps (Image menu) is selected (showing a checkmark alongside the menu item), or
  2. Automatically blend overlaps is not selected but the left hand edge of the overlap has not been edited.

Workaround

This workaround is needed only if you stitched with Swing lens or rotational camera selected for the camera type and with images that have more than 8 bits per color channel.  If you selected another camera type or if you are using images with 8 bits per color channel (JPG, BMP. 8-bit PNG or 8-bit TIF), you will not encounter this problem, so no workaround is required.

To avoid the abnormal termination, you must turn off Automatically blend overlaps and always edit the left hand edge of the overlap whenever you edit the right hand edge:

  1. When you are ready to edit the overlap region, make certain that Automatically blend overlaps (Image menu) is not selected.  If there is a checkmark alongside the menu command, select the command to remove the checkmark.

  2. Perform an edit to the left hand edge of the overlap region.  You may make any edit, however small, but you must change the overlap region.  You will know that the edge has been edited if the overlap region changes from solid line to a dashed line.  The dashed line indicates that the region has been edited with Automatically blend overlaps not selected.

  3. Do the editing of the right hand edge of the overlap region as you require.

  4. Choose the Blend overlaps now command (Image menu) to blend the overlap without receiving an abnormal termination.

Status

Corrected in V4.3.
