  Stupid question about Image ppi
Posted by: sallyanne - 09-07-2023, 03:44 AM - Forum: General questions - Replies (3)

I saw on the Internet that an image ppi /dpi can be changed within gimp. I think I have seen before that you cannot change an image to look good if the ppi is changed.
Assuming the image is already large but has a small ppi - 72. Can it be successfully converted to 300?
What I saw - 
How Do I Make an Image 300 DPI Without Photoshop?

  Where I can see if Script-Fu function calls "works".
Posted by: Strzegol - 09-07-2023, 01:29 AM - Forum: Scripting questions - Replies (2)

Hi to all.

I have simple question but I'm unable to find answer. Use GIMP 2.99(dev) but question probably is unrelated to version.

How to see error from calls to GIMP functions?

Imagine that I put this (in .scm file or in Script-fu console):


Code:
(script-fu-menu-register "non-existing-stuff" "<Image>/Fictional/Non/Existing/Menu"

Where I see Gimp complaining about this? How to know why my call to for example script-fu-menu-register fails?

  open pdf so that pages are layers and order of layers is reversed order of pages
Posted by: Cattleya - 09-06-2023, 06:59 PM - Forum: General questions - Replies (2)

From time to time I use GIMP 2.10.8 for creating animated .gif-files from .pdf files so that when viewing the .gif-file every two seconds another page of the document is visible.

When importing the .pdf-file and hereby selecting "Open pages as layers" each page of the .pdf-file is a layer on its own.

The problem is:

Assume the .pdf-file has n pages.

After importing:

Layer 1 has name "1" and shows page 1 of the document.
Layer 2 has name "2" and shows page 2 the document.
...
Layer n-1 has name "n-1" and shows page n - 1 of the document.
Layer n has name "n" and shows page n of the document.


When exporting this as .gif-file, then the animation starts with page n of the document and ends with page 1 of the document.
I. e., the animation shows the pages of the document in reversed order.

Thus, for the .gif-animation to begin with page 1 of the document and to end with page n of the document, reversing the layer order before exporting is needed.

By now, after importing the .pdf-file,  I click "Layer" - "Stack" - "Reverse Layer Order" and I get:

Layer 1 has name "n" and shows page n of the document.
Layer 2 has name "n-1" and shows page n - 1 of the document.
...
Layer n-1 has name "2" and shows page 2 the document.
Layer n has name "1" and shows page 1 of the document.

When exporting this as .gif-file, then the animation starts with page 1 of the document and ends with page n of the document.

Question:

Is there a possibility to have the layer order reversed automatically at the time of importing the .pdf-file, without the need of doing so much clicking?

  How do you smooth path lines?
Posted by: adwhitewolf - 09-06-2023, 01:23 PM - Forum: General questions - Replies (3)

Hi all. I'm using gimp 2.10.34 (version 2) on an iMac. I am trying to create a filled in path that has smooth, curved lines. Specifically the collar on a T-shirt. I draw my path, and then fill it with the desired color. But when viewed against a contrasting background, you can see how pixelated it is. The image size is 1024x1024 I just follow a path of the collar using the paths tool, then I use the paint bucket to fill it in. 
 Is there a quick and simple way to smooth out the edge of the collar?

  Release of G'MIC 3.3
Posted by: dtschump - 09-05-2023, 06:18 AM - Forum: Extending the GIMP - Replies (1)

Hello Gimp-Forum !

I would like to announce the release of a new version of G'MIC, numbered 3.3.0.
It was released yesterday, and I'm very happy with it [Image: icon_mrgreen.gif]

[Image: 776c052f4088b2c340f7b0487ab6f8025daf39d5.png]

Do not hesitate to upgrade if you are using this plug-in for GIMP, as new filter updates will be pushed only for this new version in the future.
Cheers,

David. 

PS: I forgot to give the URL of the project: https://gmic.eu

Question how to change default paste behavior
Posted by: akirapink - 09-05-2023, 02:24 AM - Forum: Gimp 2.99 & Gimp 3.0 - Replies (25)

i noticed that recently(? not sure in which version this change was made), pressing the keys “ctrl v” no longer pastes as a floating selection, but as a layer

how can i make it so when i press ctrl v, the clipboard contents are pasted as a selection instead of a layer again?

specifically not reassigning the shortcut to “paste into selection”, because that only pastes into the existing selection, and doesn't allow me to move the pasted contents outside of the existing selection

  Clone problems colour doesn't match the source
Posted by: Kev - 09-04-2023, 02:42 PM - Forum: General questions - Replies (11)

Having real problems again 

Was using clone and for some reason the colour is now slightly different than the source  sometimes lighter sometimes darker depending what I'm trying to cover 
I probably clicked on something by accident as this seems to happen to me .

I don't know if there is any thing you can click on that takes everything back to default settings when originally installed as that would be a great help.

Did once before uninstall and re install but that didn't help as it remembered my last settings.

I'm a real novice (idiot ) as far as tech goes .

Thanks in advance Kev

  Adjusting a path along a curve
Posted by: Ofnuts - 09-03-2023, 10:54 PM - Forum: Tutorials and tips - No Replies

A simple technique to make a path follow a given curve:

Make a path that is a straight line between two points o the curve.

   

Eyeball where a tangent to the curve is roughly parallel to the path line (around the middle for a regular curve). Click on the corresponding point on the line, and control-click  on the line to add an anchor,

   

Drag the anchor to the curve. Your path should be a line that is pretty close to the curve.

   

If it is not close enough, repeat the process for the parts that require it


   

Very often a single midpoint is sufficient, for instance the top of the wing is an easy fit:
