hi,
so, how's the rough/pixelated line smoothing in GIMP?
I just got done trying to use Corel PaintShop - do I have to paint a smooth line?
doesn't seem to work very well on black/white line drawings.
thanks

| Finding duplicate/similar pictures |

Recently I was looking for a means of identifying duplicate and similar photographs. Dupeguru would appear to fit the requirement, but I was unable to find a version to download which was compatible with Ubuntu 18.04.
During my search I came across https://similar.pictures/index.html by Vitali Fedulov. A trial of this very quickly identified similar pictures in a folder of approximately 2,500 images.
I hope that in the future this will be extended to enable use of the results which it finds.

| Genius tablet - minor problem |

I have a Genius EasyPen i405x. Whenever I open GIMP it is greyed-out in Input Devices. If I go to LibreOfficeDraw it works. Re-opening GIMP shows it in Input Devices and it then works. This is only a minor irritation, but a solution may help others.
GIMP 2.10.12
Ubuntu 18.04
More importantly, I think it is overdue that there be a vote of thanks to Rich, Ofnuts and others who give their unstinting help on this and other websites.

| High Pass filtering 2.8 vs. 2.10 |

The manual way of making a High Pass Filter (that is also used in RobA's script) is:
- duplicate image
- desaturate
- invert
- reduce opacity to 50%
- gaussian blur
- merge down
When you do the steps in 2.8, the image becomes 50% gray at step 4.
This is not true for 2.10, unless you set the Blendmodes to Legacy.
I know Gimp 2.10 has a GEGL High Pass Filter, but i want to understand the "wiring under the board".
The only 2.10 procedure i can up with is:
- duplicate image
- desaturate
- invert
- set layermode to 'Grain Merge'
- gaussian blur
- merge down
So what is going on ? What has changed that makes the old way dysfunctional ?

hi,
Maybe you can answer this.
does GIMP export/save to type PDF/A FORMAT?
I can't really find any info on what type of pdf GIMP can save to.
thanks.
