  Python plugin: point in selection?
Posted by: Ottia Tuota - 01-23-2021, 09:50 AM - Forum: Scripting questions - Replies (6)

Is there any way to find out, in a Python plugin, if a given point (x,y) is in the selection or not?

  May the force be with my Python
Posted by: Ofnuts - 01-22-2021, 09:43 PM - Forum: Watercooler - No Replies

Checking how ofn-enclosing-circle behaved in some complex cases I gave it a shot against a path of the coastline of Ireland. There was a bug with a very tiny island in the southwest that wasn't included because the corresponding stroke had a single anchor. That wasn't Skellig Michael (which is so small it's not in the original SVG) but that was pretty darn close.

Must be a sign.

  Just trying to fill the background layer. What am I possibly doing wrong here?
Posted by: squatcobbler - 01-22-2021, 01:06 PM - Forum: General questions - Replies (1)

I have this crazy idea. I want my background layer to be white. 

I've tried selecting the layer and doing Edit->Fill with BG Layer

It doesn't fill all of it.

So I select all of it. Try the menu item again. No. Still doesn't fill the transparent part. 

I google. Aha! Shift-B and then choose "fill selection if necessary" or whatever.  Nothing works!!! A trivial task and it just doesn't work. 

I keep selecting all of the layer and it never fills. 

I've spent an hour just trying to fill a flat background layer with white, see attachments.  I'm sorry but this is absurd.

  GEGL - Negative Darkroom filter
Posted by: rich2005 - 01-22-2021, 10:23 AM - Forum: Tutorials and tips - Replies (5)

Something to look for when Gimp 2.10.24 is released.
For those photographers out there.   In the latest Gimp 2.10.23 appimage - a new GEGL filter 'Negative Darkroom' (in Tools -> GEGL Operation at the moment)

Does what it says, processes a negative to an image for printing.  Excuse this example, I do not have a negative scanner or a light box so this was photographed in a slideholder against daylight. (basically against a window )   Wink

   


Those 'Characteristic Curve' presets might be interesting, Several under the colour option for Ilford mono film types.

  Rectangles, Rounded Corners
Posted by: Bill Wright - 01-21-2021, 11:27 PM - Forum: General questions - Replies (2)

For some reason, Gimp does not allow me to create a rectangle with rounded corners. Has anybody else experienced this issue? Does anybody know a fix?

Posted by: denzjos - 01-21-2021, 10:07 AM - Forum: Other graphics software - No Replies

If you want to convert yout GPS .gpx files to .svg files and use the .svg file as a path in gimp you can then Maperitive is the free software can help you : http://maperitive.net
1 - load the .gpx file in Maperitive
2 - tools / export to SVG (Inkscape)
3 - make a new image and load the saved .svg file as a path in gimp
As an example I've used a bike map from the Ypres Bow 14-18 convert to a path and set poppies on it.(https://www.westtoer.be/nl/doen/ieperboog-0)

  removing background of image
Posted by: JeeperMatt - 01-21-2021, 12:05 AM - Forum: General questions - Replies (2)

Hi everyone, I used Gimp many years ago but am now quite rusty. So if someone could explain how I can remove a white background that would be great. I have tried but the image loses quality...TYIA

  Pattern import
Posted by: Buff - 01-20-2021, 03:08 PM - Forum: Extending the GIMP - Replies (1)

Good day I am a newbie to Gimp attempting to import a .pat file using a Zorin platform with 2.10, having tried a number of the tutorials I come unstuck pasting the .pat file into the share folder. It appears that I do not have permission to make that addition.
Any help appreciated I have trawled to forum but found nothing relating to this issue.
Thanks Huh

  Scaling without quality loss
Posted by: Jens - 01-20-2021, 11:59 AM - Forum: General questions - Replies (6)

Dear all,



I have a pixelart image that I try to scale in gimp. This is probably just a button I need to toggle, but I have searched for more than an hour (also on this forum and on Google) but I have yet to find the answer.

When I try to scale the image everything goes well, but when I click enter it suddenly loses a huge amount of quality.


I added the unscaled image, scaled image before clicking enter and scaled image after clicking enter.



Many, many thanks in advance!!!
