Chris,

Thanks again for this page. I used the batch process and everything is
working fine now!

I appreciate your time and patience.

Just quickly scanning the plug-in code, it seems that:

This one should be pretty self-explanatory :)
"Color of timestamp" = the timestamp color

These 5 control how aggressively the selection is made and filled in:
"Threshold" = analogous to the threshold level on the fuzzy select and
global color select tools
"Grow selection after color select" = same as Select->Grow from the menu
"Grow selection befor spread" = same as Select->Grow
"Spread count" = number of times to spread (see below)
"Spread value" = same as Filters->Noise->Spread

I'm not clear on these two:
"Offset count"
"Offset value"

I also quickly looked at the batch script, and it looks like you would
need to edit it a bit to make it work - eg changing the path to your
files, and editing the settings in this function:
pdb.python_fu_remove_timestamp
so that they match the settings used when running the plug-in by hand.

HTH,
Chris

Chris,

This helps a lot and it works! Is there any documentation for this
plug-in? I am curious to figure out what the other options are for...



Rhino,
Thanks. I have thought of it. The pictures look really bad with the time stamp.

If the time stamp is always the same colour and in the same place, the
script could select that colour, (grow the selection a bit,) then
intersect the selection with a rectangle to limit it to the zone where
the numbers appear. Finally run an inpainting filter, like the one in
CImg/GMIC. Depending on the image it will look more or less obvious.

You cannot simply "remove" pixels from an image, you can only 
"replace" pixels of one colour with pixels of another.

If you plan a batch operation then I assume you're are asking to 
replace the area containing the time stamp with a rectangular block of
some colour. Is this your intension?

Another option would be to crop every image to exclude the timestamp 
from the resulting file.

You might be able to develop a script that would implement a 
simplistic bleeding of the colours surrounding the time stamp into the
area occupied by the timestamp, but such an approach would create a 
very blurry mess likely to make the resulting image unacceptable.

If you hoped to magically blend out the timestamp replacing it with 
the colours that would have been there had the camera not added the 
timestamp, then forget it. You cannot do that as a batch operation as 
every image would need to be treated individually.

[Gimp-user] removing timestamps from a photo

2010-12-19 Thread Mag Gam
I have taken several hundred photos with my Nikon D3100. I've enabled
the date time stamp therefore I see a bright yellow time stamp on the
lower right corner. I would like to remove this time stamps. I was
wondering what is the best way to do this in batch?

Thanks in advance!
