  MathMap for Linux
Posted by: rich2005 - 09-21-2020, 02:14 PM - Forum: Extending the GIMP - Replies (10)

MathMap - A Gimp plugin see: https://www.complang.tuwien.ac.at/schani/mathmap/ A new compilation tested in 'buntu 18.04 / 20.04 / Mint19 / 20 regular Gimp and Gimp-Appimage 2.10.x

Installation:
Download the zip from: https://u.pcloud.link/publink/show?code=...yMfS1SkfGy
Unzip and put the folder mathmap in  ~./GIMP/2.10/  and the plugin mathmap-full in  ~./GIMP/2.10/plug-ins (or the equivalent  ~./GIMP-Appimage/2.10/... )

There are dependencies which are probably not installed. In a terminal run

Code:
sudo apt install libgtksourceview2.0-0 libgsl23

Use: The plugin installs in Filters -> Generic -> MathMap   A very quick example https://i.imgur.com/K9oP1o9.mp4 using Mint20

The usual guarantee: there is none.

  how can I make GIF over a static image?
Posted by: kenny1999 - 09-21-2020, 12:44 PM - Forum: General questions - Replies (18)

Hi
I am not expecting very professional work, just want to do it for fun. So I hope the
steps aren't too complicated...

I want to make an image of dinosaur walking around in the background of a place.


As a result, I think I'll first need to create a GIF image of dinosaur walking around.


And then, to put the GIF image on top of a static image (the place)

Would anyone suggest me the simplest way to do so??

Just for fun, not expecting too detailed.... Thanks

  Akira Fuji effect?
Posted by: Marty0750 - 09-21-2020, 03:17 AM - Forum: General questions - No Replies

Effects such as Softglow and Bloom do not quite make it. The Akira Fuji effect selectively blooms only the bright stars in an astrophoto while leaving the fainter stars unaffected. This makes the constellations stand out easily. Any tips or plugins on how to make it work in GIMP?  Tried SBLUR in IRIS but that too it just does do it.

  Preview GIF before exporting
Posted by: meetdilip - 09-21-2020, 12:26 AM - Forum: General questions - Replies (13)

Hi, is there any method to preview a GIF before exporting it to a file ?  Also, is there any method transition effects like " dissolve ", " fade " etc while creating GIF ? I am hoping that someone has written a script for the same. Thanks.

If one has taken a picture with the vertical lines ok and the horizontal lines not parallel, then the 'Align to path' (ob-align.py) plugin can help : https://www.gimp-forum.net/attachment.php?aid=275

  damaged photo
Posted by: vpkumar - 09-20-2020, 12:00 PM - Forum: General questions - Replies (4)

I am trying to repair this badly damaged b&w old photo. I have tried heal and clone tools , but they dont help much. The dress is supposed to be off white color. But using paint brush is ok, but when I change mode to overlay or softlight, the damages reappear.
I also trie wavelet decompse, but this also did not help.

Can you please suggest the best way to repait this photo. 
I have left out the face.

  Why is antialiasing not working
Posted by: gib65 - 09-20-2020, 06:30 AM - Forum: General questions - Replies (2)

Hello,

I have a selection set and I want to fill it with the paint tool. I want the edges to be smooth so I turn on antialiasing:

[Image: antialiasing.png]

But as you can see from the image, the edges still seem fully pixelated.

What am I doing wrong? How do I get antialiasing working with the paint tool?

Question Curve Bend help?
Posted by: Amy de l'ABC - 09-20-2020, 01:30 AM - Forum: General questions - Replies (5)

Hi everyone Smile

I'm new here; have been trying for a couple days to get this to work properly, and I've finally given up and decided to ask for some help, haha.

Basically, I'm attempting to curve an image (not a path, just an image) along a path. Curve bend seems to me to be the way to go, but I'm having all sorts of trouble actually using it...mostly because the grid with the points in the dialog box is so TINY. Like...idk if it's meant to be so small, but the grid is like...an inch long maybe? And the mouse movements I have to make to adjust are absolutely infinitesimal. My hand-eye coordination isn't good enough for that! XD

Anyway...the ideal solution would be to be able to load the points data from an SVG or something, so I could edit my path in Inkscape. If there's no way to do that, are there alternatives that allow me to edit the points either like...with the arrow keys or something, or in another program, or even (as big a pain as it would probably be) in a text editor or something? Is Curve Bend even the best way to do this? Tbh I'm still finding GIMP a bit counterintuitive in a lot of ways, so I have a difficult time with it sometimes.

Thanks for any help you can give!

Oh, and so that you don't have to check my profile--OS is Windows 10, GIMP version is 2.10.20 (revision 1).  Smile

  Image in in Alpha Channel & Can't Move It
Posted by: Tek420 - 09-18-2020, 10:38 PM - Forum: General questions - Replies (7)

Hi All,

Not new to GIMP but never use it because I always hit a wall doing things almost immediately.  I really want to learn this hench my question and not giving up.

I have an image, a .png file exported from Inkscape, that has the attached pics for 'Layers', 'Channels', and just a little of the actual image.  From what I see and I think is the problem is the layer is the 'Background' and the 'image data' is all in the Alpha Channel only.

         

My issue is I want to erase some of this to simplify bits but as I said the 'image data' is in the Alpha Channel so I can not use erase and have it do anything.  I see in the 'Undo Hostory' that it performs an Erase 

I have tried all sorts of things from filters, copying/adding/deleting the layers/channels to another, breaking apart, converting into different file types, ... too many to list or remember and NOTHING I can do can allow me to erase some of the lines.

The question I am asking is how can I get the 'image info' into another channel or layer or format or ANYTHING that would allow me to erase some of those black lines to alpha?  I know I have done this in the past but not constantly and can never figure out the 'why' I can't.  I have been Googling for hours and it's just a strange thing to explain and type out for a search and all I get is basic stuff on the alpha channel that has not helped.

ANY help would very greatly be appreciated!!

Dave

Sad I don't remember loading fonts to be this hard!
Posted by: mordhau5 - 09-17-2020, 09:44 PM - Forum: General questions - Replies (1)

Hey all! Recently got back into working with GIMP on Windows 10 after a PS membership ran out, as it's pretty much the best open-source alternative. I've been trying to load in some fun new fonts to work with but GIMP will not detect any new fonts despite my best efforts. What's weird is some older fonts I installed a while back do show up, but nothing new. Also, all new fonts DO show up in every other app I use. I've been reading up on it for a few days now and tried the following:

-installing fonts directly from the TTP/OTF file
-dropping fonts into the Windows/Fonts folder
-Restarting GIMP
-Reloading fonts within gimp
-Adding the Windows Fonts folder directly to the list of folders GIMP uses to source fonts
-Clearing font cache
-Restarting Computer
-Reinstalling GIMP
-Updating GIMP to newest version

Lots of restarting in particular. Does anyone have any ideas?
