A small Idiosyncrasy in Print Composer that must be avoided: If the "world file" option is selected in the composition, it should be impossible to change the image resolution (in dpi's) after save as image dialog. If we alter that resolution using this step, the final image will not be compatible with the generated "world file". Everything will work as expected if the resolution is selected in the composition tab and the value is not altered after the "save as" dialogue box. I suggest that if the "world file option is selected, the image resolution will appear grayed out after the save dialogue box appears.

  • Subject changed from World file in Composer and save as image Idiosyncrasy to [composer] Incorrect world file generated if dpi changed in image export options dialog
  • Priority changed from Normal to High

A better fix would be to ensure that the world file is correct even if the DPI is changed...
