| Newbie - batch resizing of images |

I've used GIMP for a couple of years, always interactive, but now I would like to resize a rather large number of TIF files to a standard format. I have two types of files, "fronts" (t???r???-???.tif) and "backs" (t???r???-???b.tif)
Manually, I would
- open the file
- change the only the canvas, to 2310 x 4842 pixels
- only for the "backs", add an "x" offset that is the difference between 2310 and the previous size
- click resize
- flatten the image
- export it with Deflate compression
- quit
and repeat (ad nauseam).
Is there a simple way to do this scripted. I'm a z/OS guy, and although I've RTFM, Script-Fu might just as well be Chinese to someone who's used to PL/I and REXX. And to boot, I really would like to have something that I can enter from the Windows command-line...

| Smoothing jagged edge |

I have some images with jagged edge; I made the background transparent and it was contrasting so I could leave little of the color fading in the result and the border not being gradual is obvious. I'd like to have the jagged edge smooth.
My first thought was anti-aliasing but I'm not sure GIMP have that and I wouldn't know what the best or most efficient way to go about with that. I did a search and the only relevant page I found was Fixing Jagged Image Edges with Gimp | Jafty Interactive Web Development, which I wonder if there's a better method.
Thank you kindly for your help

I never bothered with promoting my blog, so i dont have many followers or daily hits (between 50-80 a day seems the average after 4,5 years).
Yesterday i posted a link to a new Inkscape tutorial on the Inkscape subreddit as an experiment to see how much traffic that would generate.
That gave me 25 hits in 18 hours so far.
I dont know, i use reddit for discussing movie and television stuff. It doesnt appear like a good place for helping with graphics design problems to me, but younger people seem to prefer it compared to forums.
I tried G+ for a while and found it awful. Never bothered with Facebook.
Do people use it as a forum substitute ?
I guess youtube is the biggest thing for getting content out, but i cant see myself investing in the tech and im not used to speaking english, so that might sound a little odd....
Also not sure about the future of YT. It seems since the adpocalypse, YT is on the decline and something different will appear at some time.
Or net neutrality will change it all.
Opinions ?

| Curve Tool mysterious x: |
|
Posted by: Laserulo - 12-16-2017, 08:37 AM - Forum: General questions

When I open my curve tool I find there is a vertical line with the label 'x:193' where the number is a position on the horizontal axis. This position is never the same i.e. it varies from one image to another. I've tried to deduce what it means but am at a loss. Gimp context help provides no clues. Any suggestions?
