georeferencer seem well turn map and create *-modified.bpw or *-modified.jgw but these files are without effect on *-modified.bmp or *-modified.jpg.

It's OK for *-modified.tif

Testing with .jpg, I can repeat the issue. Renaming the generated jpeg-modified.jgw to jpeg-modified.jpgw or jpeg-modified.wld displays the JPG with world info. Seems to be an issue in gdal library. I'm on Ubuntu 6.10 with gdal-1.3.1. I'm recompiling from source and see if I can find anything.

  • Resolution set to fixed
  • Status changed from Open to Closed

Georef plugin always writes in TIFF-format, so even thoug the ending is .bmp or .jpg of the modified file, it's created as TIFF file and GDAL looks for a world file named .tfw or .wld.
Changed the dialog box to indicate this, and also changed the default edning to always be .tif (and .tfw).
