  How do you "smear" colors across a certain area? To make backgrounds look natural.
Posted by: guest273 - 09-11-2023, 07:05 PM - Forum: General questions - Replies (6)

Hey there!

I just don't have the Vocabulary to do a proper google search since I don't know how this process is called.

Basically:

Here (on the left) is the briefcase that they used in the movie Pulp Fiction to make it shine when the character Vincent opens it.

I want to remove the area with the lightbulb & its components and only leave the authentic briefcase.

So, I cut out the area with the lightbulb but now how do I "smear" the nearby colors to make the briefcase look naturally empty?

I think that splitting the coloring-in in multiple 'sectors' would make sense - one tone for the 'bottom' of the base, one for the 'right side' of the case and the last for the 'backside'.

In the end I want to use this 500x500 px image in a 1000x1000 4 panel meme that I am making, as I want to place an object 'inside' (over) the brief case. So it doesn't need to look perfect, only decent enough for a person looking at said image for about 3-5 seconds to not notice that the background coloring looks totally whack.

Any help is appreciated! I plan to check back here in a day or two. Smile

Thank you,
guest273


I want it to look better than the briefcase edits in these pictures:

Generate Practice Images with Pixlr AI
 
Pixlr AI  presents a useful way to generate images for photo editing practice or tutorials.
Here, this will be for a tutorial on combining images with Wavelet Decompose.
This can be accomplished by:
 
1.     Use Pixlr AI to create  an image, for this example “brick tower with trees under stormy skies”, to use for a foreground image.
2.     Search Wikimedia Commons for suitable background image. The phrase here was “mountain landscape”.  This could also be done with Pixlr AI, but I preferred the display of options provided by Wikimedia Commons.
3.     Apply Filters Enhance Wavelet Decompose to the foreground image.
4.     Place the background image as a layer above the first scale with Grain Merge layer mode.
5.     Free Select any area or areas in the foreground image that should not be blended with the background image.
6.     Fill or paint these areas in the background image with 50% Gray.
7.     Adjust the opacity of the background layer.
The combined images should now present.

  Put one object in front of another
Posted by: sl60 - 09-10-2023, 05:09 AM - Forum: General questions - Replies (3)

Let's say you have a photo of a fence and you want to put a number of photos of people behind it--but you want each person behind the other people. What would be the easiest and simplest way to go about it?

Question various small issues with gimp 2.99
Posted by: akirapink - 09-09-2023, 03:19 AM - Forum: Gimp 2.99 & Gimp 3.0 - Replies (3)

1. i'm pretty sure this is a recent change, too:
when i'm checking various layers, the yellow-black striped outline around the layers doesn't update to reflect the one i've selected until i do something to that layer, such as click on the canvas with any tool
is this a bug? it's a downgrade - not being able to tell if you successfully switched to the layer you wanted so it certainly seems like a bug


2. this next one i think was an old change, but i can't move the viewport while holding a selection box handle anymore. why? this was so useful to get precise measurements across large distances in gimp 2.10


3. also, fonts are partially busted in the flatpak version. i cannot make text bold or italic, the toggle button is there and i can turn it on and off but it doesn't do anything

  Get back the [Tool Options] in one click
Posted by: PixLab - 09-08-2023, 11:18 AM - Forum: Tutorials and tips - No Replies

Recently on reddit someone gave a tip in a very simple way to show back the Tool Options...
Why I never ever thought or tried this, it's something I still don't understand...

Anyway, there is no need to go to the top menu Windows > Dockable Dialogs > Tool Options => just double click on the tool you are using in the ToolBox!
If the Tool Options dialog is not open or you don’t find it, just Double click on the tool you’re using to bring it up. The dialog will flashes if it's opened or the dialog will open and flashes.
Yes as simple as that!

No need to say that I tried it, I did close the Tool Options, double click on a tool in the toolbox, and Voilà... the Tool Options appears on the right side (yeah just need to transfer it to its proper place, anyway if you pass by the top menu it's the same > appears on the right side Wink )

  GIMP Tutorial
Posted by: trlerwick - 09-07-2023, 03:58 PM - Forum: Tutorials and tips - Replies (12)

Use GIMP Hidden Images for Shadow Removal
There are hidden images in the GIMP layer mode display. There is nothing profound about this, the layer mode presents as a solid color. When a filter is applied to the upper layer, the layer mode interaction changes, and an image appears.
The hidden Divide layer mode image together with Colors-Exposure can produce a very effective shadow removal.  
1. Duplicate the image.
2. Use the Divide layer mode.
3. Apply Colors-Exposure to the duplicate.
4. Adjust the sliders to make a preliminary image.
5. Adjust the opacity slider for the layer to complete the procedure.
Like any procedure, this one works on some images, not on others.
To capture a hidden image:
1. Apply the filter of choice but do not click OK.
2. Apply Edit Copy Visible and then Paste As New Layer. This will cancel the filter and the layer image will not be affected.

  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?
