Help please Newbie ( me ). I need to save file with extensions JPEG or PNG so i can upload to Facebook, How can I do this ?

I have Gimp 2.10

I want to convert an image to an icon.

I did that alright with some other tools - online web thing.

But I need an icon of <6KB  and the web thing produced something around 30KB.

I need <6 KB and < 90 x 90 px

So I took to Gimp to do something about it but I've finished up getting lost.



I export as .ico after doing the theme thing etc and I got a 768KB file.

Probably this is quick, easy simple task.  I need to ask for help.

Can someone set me straight here please - how to change my .jpg photo file to a an .ico file after selecting a portion of it?  AND have that ico file be less than 10KB ?

I went to Colors->Curves

I created a color curves preset....and exported that preset to a file. 

Now if I open an image, and apply that color->curves with the preset, and export the PNG file out. The image is properly saved with the color curves correction applied.

If I go to
File-> Batch Image Manipulation
Add the Manipulation set,
Color Correction
Check off : "Change Color Corrections From Settings File"
and pick my Color curves preset I saved....

After the batch process, the images I batch processed, the ones exported and saved out to a separate directory, are all whited out images.....

Hi everyone

I have some problems with saving new patterns in gimp 2.10: I recently bought a new laptop and installed Gimp 2.10 - up till  that point I had always used 2.8. I like the changes, except for the fact that I can't seem to save new patterns with this version. With 2.8, I exported newly made patterns to 'users\username\gimp2.8\patterns', but that doesn't seem to work anymore. So then I read somewhere that you instead have to go to 'C:\Users\your-name\AppData\Roaming\GIMP\2.10\...', but I can't find Appdata in the Users map either - and the Appdata maps I find when just searching in File Explorer don't contain any Gimp items either ... I also can't find the 'data folders' page in 'Preferences' in this version. 
Can anybody please help me with this?
Note: You probably already realized it, but I'm a complete amateur when it comes to stuff like this, so excuse me if the question is kinda dumb. 

Thanks in advance!

I'm trying to edit a GIF I've downloaded.  

When I try to import a layer from another image that I've edited to the gif image, the colours are affected.  

I want to duplicate and add this layer to each of the gif layers.  In short, I want to change the face of the person in the gif.

Why are the colours changed on the imported layer?  I have a feeling its something to do with the channels: the import original has the RGB and Alpha channels, the gif only has Indexed and alpha.

Any ideas?

Just put the latest version of G'MIC into Gimp 2.10.8 under Ubuntu 18.04. It does not appear. When I start Gimp from the terminal it says "libQt5Widgets.so.5 not found".
Advice please as to where I can find this file and how to install it.

(It also tells me that canberra-gtk-module is missing, but it has been reporting that for some time and appears to make no difference to the operation of Gimp.)

I have some raw image data (not the RAW format) that is composed 32-bit floats that I need to find the differences in.  I'm thinking a simple subtraction would be sufficient and I'm able to do that by simply subtracting the images pixel by pixel but I would like to be able to display the resulting image for management. 

Is there a simple format for 32-bit floats that I can transform my data into that GIMP 2.6 can read?  Is there some way that I can tell GIMP where the data is and the dimensions of the images?

Hello!
So, I have this two images:

https://flic.kr/p/2dj483V

https://flic.kr/p/2dj2XoX


The first one has those diagonal lines all over the place, and the second has that rainbow effect, more notorius on the mountain but it's all over the image.

I've applied the Descreen plugin on the first one, for it seemed to be a Moiré effect, but, besides removing some other patterns, had almost no effect on the lines themselves. Tried removing the "stars" on the Fourier filter, to the almost exact same result.

As for the rainbow effect on the other one, I have no idea of what it could be, and I couldn't find any techniques for removing it, so here I am, asking for help for both those images.

The first one is in 600ppp, second one in 300ppp.

Thanks!

Hello gimp forums!

So I've had this idea for a painting for a while which will include 70 of my favorite albums/eps

Is there a way to make every image the same size cus of right now all of them are not and I think it will look more neat if they're perfectly lined up and the same size.

I'll attach a picture of how it looks
