This problem started to happen when I download the newest update for Gimp 2.10. When I try to export it, their is message pops up that says, "Saving 'C:\Users\keifer\Pictures\grey bricks.xcf' failed: Error creating 'C:\Users\keifer\Pictures\grey bricks.xcf': Error opening file “C:\Users\keifer\Pictures\grey bricks.xcf”: No such file or directory"

That's the error message I get right after clicking on 'File/Export as ...' try to export a file to the desktop.

Small print of error diagnostic:

Error opening directory '/Users/<myuid>/-
Desktop': Operation not permitted.

Interestingly, after clicking on 'OK' in the diagnostic pop up window, it clears and I am able to export the file to the desktop.

So at this time, it's an annoyance.

I tried uninstalling/reinstalling Gimp 10.2.22 rev 3 to no avail.  It is true that I download and install apps to an admin account on my iMac, and then run apps from my non-admin user account.  Old habit that may no longer give any form of security, but other 3rd party apps not seeing this problem (yet).

Couldn't think of a search handle to find others with the problem, but if anyone has seen complaints about this already, please point me in the right direction.  Otherwise I'm open to any ideas about why this is happening.

OS: Big Sur
device: iMac 27"

I'm using Gaussian Blur (Filters > Blur on the menu bar).

I'd like to increment the value for Size X (Standard deviation for the horizontal axis) in very small steps while using the Preview/Split View options to monitor the results.

Using the Up/Down arrow keys I can vary the Size X value by a factor of 1, but can't find a key, or key combination, to vary the value by 0.01.

Does anyone know if this can be done?

One way remove unwanted moving persons from a scene is take two or more photos with little time between and, put them in layers and wipe out the unwanted persons. If the photos are taken handhold (with care), there is always a little difference in POV. The challenge is to align the photos in gimp. I used two photos in this quick made example, load them as layers and make a two paths with 4 points on the same places of the two photos. Then I used following plugin from Ottia Tuota on one photo (remove one layer): Filters / Distorts / Perspective transform / Perspective transform - 4 points to 4 points. I then load the first (unchanged) photo in gimp and copy the corrected photo on a new layer. Now both photos are aligned and I can wipe the unwanted person. I think this can be automated but with this example I just want to find out if this alignment in gimp was possible. 
I want to remove this person (he was in different places on two photos), 2 paths are made :

Hey everyone, I'm was just wondering how to warm up an image, I also noticed my version of GIMP 2.8 is missing a lot of options in the color settings such as exposure and color temperature.

Hello,
I am new in this forum. I would like to work with Gimp and Darktable. My problem:
I installed Darktable 3.6.0 and then Gimp 2.10.24. When I start Gimp and try to open a raw file then Gimp reports (translation from german): "There is no raw loader installed to open "Canon-Raw" files.
Can you please help me? Thank you.

I have a black and white photo and I want to colorize the face only for a face swap.  I do have plenty of color pics of the same face, not sure if I can use them with this. What's the best way to accomplish this? I don't mind taking the time and effort to do a good job

I made a small plugin to join strokes of a path. Only after finishing it I found that Ofnuts has an older plugin for the same purpose. But somehow, I was not very much surprised... But my plugin has different features, so I guess its publication is justified. Ofnuts' plugin is in his collection ofn-path-edits.

Suppose you have a path with several strokes as here on the left:

   

Some strokes have an end close to an end of another stroke. This plugin enables you to join such pairs of strokes, as is done on the right.

In this example I deliberately made the path such that the stroke ends are not so very close, just to show the effect clearly.

But suppose you have two strokes whose ends are practically at the same spot. Then you might really want to join the strokes into one. Or you have one stroke which is not closed but should be and its end anchors are at the same spot. This plugin closes the stroke properly.

To get the plugin, go to

http://kmarkku.arkku.net/Path_modify_fil...aster.html

scroll to the bottom, and click the right download button ("Join strokes"). You get a zip file. Unzip it and place the one file it contains (join_strokes.py) in your user's plug-ins folder. Then (re)start Gimp. To use the plugin: in the Paths tab, right-click a path and follow the links Tools > Modify path > Join strokes.

I envision two cases where this plugin might be useful. First, suppose you are working with a picture where you want to extract an object. And you do it with the path tool, tracing around the object. You get a long path consisting of a large number of closely spaced anchors. And then somewhere along the way you left accidently small gaps. With this plugin you can close the gaps and get one long stroke. (At least if everything goes well: The plugin does not know which anchors belong together; it works only by distances.) I just wonder if there is some old tool for this task too...

Second, you can build a figure from several strokes and afterwards join the strokes to one. The idea is the same as in Ofnuts' documentation for his plugin (as I later found out). I made the small path on the left.

   

Then I copied and flipped it three times. Using guides (shown here) I moved the 4 paths to the positions on the right. Then I merged the 4 paths. Now I had one path with 4 strokes, forming one figure. The stroke ends were practically on top of each other. Then I called my plugin. It joined the 4 strokes to one closed stroke.

The plugin lets you decide how close stroke ends are joined together. The default distance is 0.5 pixels. In the first picture above I used 40 pixels.

The plugin allows you to decide how the joining is done: either by replacing two anchors with one new anchor; or putting there a small smooth arc; or putting there a small straight edge. Here is an example of each:

   


The plugin also allows you to use a selection to restrict the effect to only some stroke ends.

Please report any erronous functionings. All suggestions are welcome.

Hi, I've recently been experimenting with path stroking and have been getting some great results generating art using ink brushes.

What I'm looking for now is a way to incorporate more randomness into the path that is stroked by the brush. I find that when I use the same brush settings manually this introduces interesting effects most likely from a variation of speed which I'm guessing equates to pressure on the pen. Essentially, I'm looking for a way to stroke a path to turn the top line example (created using stroke path) into something more like the bottom example (created manually).

Does anyone have any ideas on how to go about doing this?

Thanks!
 

hello everyone

I usually manage to troubleshoot on my own by searching on the internet
but I'm comming here because I really don't know what to do anymore ;-;

gimp sometimes freaks out, switching tools back and forth when (for example) I hit the edges of a toolbox 
it started doing this around version 2.8 or 2.6(?)

I used to click on tools to reset the behaviour and go back at drawing
it wasn't something I couldn't work around
but now, it came to a point I absolutely cant draw anymore


I do 2 strokes, and suddenly the brush start flickering between colors and tools

it also fixates on the tool options doing that highlight 
as if there's something important for me to check there

I tried:
- uninstalling and reinstalling gimp 
- same for the tablet driver

- preferences>tool options>reset saved tool options to default values
- preferences>input devices>reset saved tool options to default values
- turning off my mouse and touchpad in case they were interfering
- deleting the gimp folder in my %appdata% to get rid any 'user profile' info
- and ofc I restarted my pc multiple times while trying all these things..

I tought maybe my tablet died... so I bought a new one which didn't arrived yet..
but then I tried using my friend's tablet to see if the problem would solve- nope! the issue is the same!
I tought maybe it's my pc's issue so I tried installing krita and see if the issue happens there (using my old tablet)... and nope! 
I can work on krita just fine!

so I'm considering to abandon Gimp...
but I've grown using only Gimp since 2008 ..it's frustrating..


thank you so much for your time and attention <3<3
