Hi
I'm trying to make an animation that can play over a video. I have 20 files saved as .png so that the end file can be placed over a video so that it shows through the clear area, but when I run the animation playback all the images remain on the screen. If I save them as jpgs of course it's fine.
What's the best way to do this whole thing?

Playing with:
- Neon Edge
- Wind plug-in
- Gradients
   

edit.
maybe this time I got a better result
   

I am wanting some help with blurring parts of a photo...for example blurring the face of a person in the photo

I am using GIMP 2.10.8 on Linux and I have a problem with colour management. I work with RAW (NEF) files and use Darktable for RAW conversion. Most of my work is done in sRGB colour space so Darktable's output profile is set to sRGB (web-safe). In GIMP, Colour Management is enabled and the preferred RGB profile set to GIMP built-in sRGB.

The colours appear exactly as expected during the processing and the completed image is generally exported as a JPEG. The viewer I normally use is Gwenview. Here again the full-sized image is displayed as expected, but the thumbnails are much darker. If I look at the EXIF data in Gwenview I find there are not one, but two EXIF tags titled "Color Space" - one shows "Uncalibrated", the other "sRGB".

If I take a JPEG straight from the camera, both these EXIF tags show "sRGB" and the thumbnails display correctly. Subsequent processing in GIMP does not affect the EXIF tags or the thumbnail display in Gwenview. Exactly the same behaviour occurs with DigiKam as the viewer.

If before exporting from GIMP, I deliberately click Image -> Color Management -> Assign Color Profile it makes no difference to the situation described above. However, if I take the exported JPEG derived from the RAW file via Darktable and re-load it into GIMP, then add "Assign Color Profile", the thumbnails in Gwenview (or DigiKam) display correctly, but the two Color Space EXIF tags remain as "Uncalibrated" and "sRGB".

I am baffled by this behaviour, which is admittedly more of a nuisance than a serious problem, as each image displayed singly is fine and subsequent processing to print works perfectly. However, apart from the irritation of having very dark thumbnails displayed in the viewer I am concerned about the two conflicting EXIF tags and wonder whether this might cause a problem where the images are displayed on another computer, e.g. for competitions.

I would be very grateful for any explanation and hopefully a fix for this problem.

Hey guys, I have been reading around this subject, how much size upscale and size downscale can be done before significant pixelation and significant degradation of image, and haven't found many correlative answers, other than every software behaves different.

Specifically I'm thinking of an image with this qualities: - 23 megapixels camera resolution and 5520x4144 pixels .jpg - treated in Gimp and rendered in .png with alpha layers. After all the reading I did I settled on nohalo for upscale, and lohalo for downscaling. Sometimes I keep nohalo for downascaling as well. 

I'm transforming my images to 32 bit floating point precision with max resolution (1.000.000 ppi) in Gimp when first opened.

But the heart of the question is, how much upscale and downscale generally can be done to an image before it degrades or pixelates in Gimp?

I have two questions regarding Python-fu plugin user interfaces.

1. Let say I am integrating two or more algorithms into my plugin. The user choose the algorithm with the PF_OPTION control. I would like the plugin user interface to update itself by hiding or making visible certain UI controls. Is it possible to achieve this behaviour with Python-fu? If not, is there any way to achieve something like this with any other tool?

2. An image is worth a thousand words. Instead of showing a PF_OPTION with a list of names trying to describe the output effect, is it possible to have a PF_OPTION showing a list of example pictures of the effects? I'm not interested in generating a preview!!!

Hi everyone! I'm brand spanking new to GIMP (all photo editing software actually) but I downloaded it with one specific task in mind...to learn howt  o create my own detailed paint by number that I can print onto a canvas and paint myself.
Does anyone have the knowledge on how to go about this and the willingness to explain in detail what I would need to do?
Thanks in advance!

Hey all,

I'm ultimately looking to cut out x percentage of a cicular ring and center it perfectly when I'm finished.

Embarrassingly I've spent hours trying to do this with no luck, and no relevant google searches that I could find either. How would one go about doing this?

If I choose a kind of brush group, I can't activate another kind of group brushes.
If I clic on the grey items on the menu, they do'nt react. There is also a menu on the bottom of the brushes but it is also unclear to me how to use it. 
   

Is it a bug or is there something I miss ? Thank you for your answer in advance.

hello,

about a week ago my plugins started acting funny.  some plugins (ex. duplicate to another image) give me an error when executed.   other plugins have disappeared altogether (ex.heal selection).  everything else seems to be working as it did before.

i made no updates to the software except to add artwork i was currently working on.   it just started suddenly..

i have attached the error screen i get when trying to run "duplicate to another image"  as well as a screenshot of my plugins folder.

i am running GIMP 2.8.22 on windows xp.

i have not tried a reinstall yet.     

thanks in advance for any help on this.
