[Bug 2081896] Re: enblend and enfuse ignore the -f option and set the image position to the position of the first image in the list

 

so i got a bit too zealous cleaning up the code before submitting the
patch and didn't check again. the enblend-extra,diff patch needs to be
applied on top of the previous patch. sorry

Title:
  enblend and enfuse ignore the -f option and set the image position to
  the position of the first image in the list

Status in Enblend:
  New

Bug description:
  enblend/enfuse set the position of the image to the upper left corner
  of the the combined images. this is wrong. it should be set the x/y
  offsets passed to the -f argument. because of a bug in the blacklisted
  exif keys the program would write the x/y position of the first image.
  even after fixing the regular expression and setting the position to
  what was given in the output file, the programs would still ignore the
  offsets because then it would filter out the x/y position from the
  data read from the file list and overwrite the already existing
  position when writing out the new metadata. the fix is to sanitize the
  data read from the files to be blended, read back the old metadata
  from the blended file, merge it with the sanitized metadata and then
  write it back to the file. i'm attaching the patch to fix this.
