#2814: in georeferencer, filename confusion with multiple georeferencing
--------------------------------+-------------------------------------------
Reporter: fhof | Owner: timlinux
Type: bug | Status: new
Priority: minor: annoyance | Milestone: Version 1.5.0
Component: C++ Plugins | Version: HEAD
Keywords: georefercencer, | Platform_version: Win XP SP3 ; qgis 1.4
Platform: All | Must_fix: No
Status_info: 0 |
--------------------------------+-------------------------------------------
Context:[[BR]]
While georeferencing multiple maps with a simple linear transformation.
How to reproduce:[[BR]]
* Using the plug-in, georeference a first image (for ex. map1.png).[[BR]]
* When completed, open an unrelated image (for ex. map2.png), and answer
"No" when asking if existing points have to be saved. [[BR]]
* Define enough points for the georeferencing. [[BR]]
* Click on "Start georeferencing". A dialog warns that the image already
contains georeferencing data, which is not the case. It is a confusion
with the previously georeferenced image. The warning proposes either to
overwrite the world file or to cancel.
Workaround: [[BR]]
* Go into "Transformation settings". It show you the same parameters as
for the previous georeferencing. [[BR]]
* Just click OK, the parameters will be reapplied, with the current image
path being considered. [[BR]]
Although the workaround is simple, the behavior is a bit strange. When not
paying enough attention on the warning message, some existing data would
be overwritten.
