I can't replicate the problem unless I'm using my screencapture software (ShareX) which seems to interfere with the layer drag and drop. I'm using Win 10. I've also noticed the same problem with other screencapture software. I suspect this might be your issue too, since you are obviously using screencapture software to record the behaviour.
Anyway, I can ...
There are several programs that are known to interfere with Gimp drag&drop on Windows (assumed since you didn't mention the OS): Kaspersky Antivirus,Camtasia, Camstudio, SnagIt, TuneUp, DisplayFusion...
About any program thats need to watch what happens in other apps (screen capture, etc...) is suspect.
GIMP is different from Photoshop, but also similar in many ways. One of these differences is its behaviour when you copy and paste. Pay particular attention to step 3 below - it's different from Photoshop!
Make a selection
Copy Ctrl+C, then Paste Ctrl+V
In the layers panel hit the New Layer icon to anchor the floating selection to its own layer, ...
I've tried using alternatives sprite-editing programs to remedy the issue I had with Gimp, but they all have one or two things that make still makes Gimp a superior choice: aside from Krita.
So based on what Michael said, I decided to test the recent version of both Gimp and Krita on a Windows 7 computer instead of the Windows 8.1 computer I often ...
Once you have done a rectangle selection (and are still in the selection tool, you can Alt-Control-drag the selection. Note that:
this is a Cut, not a Copy
this create a "floating selection", you have to anchor it (Ctrl-H) when you have set its position.
I'd try the following approach:
invert the selection, to make sure only the head is selected (currently anything but the head is selected)
paste as new image
From there, you can export it as usual, if the image turned put to be as expected.
GIMP does currently have no way to directly export selected parts to image files, unless you want to venture ...
The simple technique
Use the Curves tool.
If you look at the image histogram:
The hump (1) is a peak frequency of dark pixels and is your text
The hump (2) is a peak frequency of light pixels and is your background
No pixels beyond (3) because your background is rather dark.
So with Curves, you make a diagonal between (A) (everything darker will be pure ...
Known bug, fixed in 2.10.16. If it's a real bother and you can't way for 2.10.16, go back to 2.10.12 (bug is only in 2.10.14).
Note that this bug only changes the "print definition" metadata, there is no impact to the image pixels.
If you look at the RGB channels, the biggest contrast in on the blue channel (this is the opposite color to the yellowish tint of the paper). So, drag the Blue channel to the canvas to copy it as a layer. Re-activate the Blue channel which got de-activated in the process (otherwise there will be color shifts later) and select the copy layer in ...
Here's one method, there may be others. This is all done in GIMP, without the need to use any other applications, or plugins.
Paint out most of the worst marks left around the design using white, this will help clean up the image before you begin. You don't need to go crazy with this, just clean it up a bit.
Sample the darkest red using the eyedropper tool, ...
I use Paint Shop Pro primarily, but I suspect the same process could be used with other image editors. According to this wiki, one requires the Separate or Separate+ plug in for this process if performed using GIMP.
I split the image into CMYK channels and deleted the resulting black and cyan images. The remaining yellow and magenta channels appeared nearly ...
Windows positions and docks are defined in the sessionrc file in the Gimp profile, which is a text file that can be edited with a regular text editor.
PSA: This is done by a trained professional, imitate at your own risk
You can possibly start a new dock with a dialog you don't use (for instance, Buffers) close Gimp, edit the sessionrc file (keep a copy ...
You should be able to use an image mask to get the effect you want. Masks are non-destructive ways of editing photos. A mask is the same size of a layer it belongs to, but its grayscale only. Anywhere that is white will be fully visible (opaque), black will be invisible, and any grey will be somewhere inbetween. 50% grey will be 50% opacity.
Import your ...
There is no "paintable area" at the image level. You paint on layers, and layers have boundaries because layers can be smaller than the canvas (or offset from the canvas) (for instance, text layers are normally just big enough for the text they contain, so can align them and stack them vertically).
You can enlarge (or shrink) the canvas using Image>Canvas ...
Resize the canvas using Image > Canvas Size to the required dimensions, you can click and drag the thumbnail to position it, or enter an offset, or centre it. Click Resize.
In the layers panel, select the layer you wish to expand, and click Layer > Layer to image size - now you can paint on the whole layer.
You can paint on a transparent layer and then apply brightness contrast.
But there are possibly better ways:
You can sample the colors on both points to set the foreground and background color, and the use the FG to BG (RGB) gradient.
Start the Blend too and click and drag to create the gradient
You can then click on any extremities ...
We are found some valuable resources, It seems you are finding it difficult to pick multiple layers in GIMP. Do you want to know about how to select multiple layers in GIMP? You are just at the right place.
You can find the best solution here.
Most of the time we use Photoshop as image editing software. Photoshop easily give us the option to select ...
Using ImageMagick's identify -verbose command and comparing the original version against a version un-optimized in Gimp (Filter>Animation>Unoptimize)
The original version doesn't show an alpha channel in the first frame, while the Gimp one does. The alpha channel is of course necessary to support transparency.
The original version as a comment that ...
Until our displays are a sheet of transparent glass, all images are displayed above a background that shows through the transparent parts of the image. Outside of web pages, where the background shall be whatever is rendered in layers below the image, what that background looks like is fairly arbitrary and depends on the image viewer. Gimp (like some others) ...
It isn't possible. Linking layers works regardless of groups. You'd have to unlink layers you don't want to move together.
Use groups to organise your layers instead. Use links only when you want to link layers regardless of grouping.
With the move tool, and the group selected in the layers panel, you can toggle between "Pick a layer or guide" and "Move ...
I think the accuracy also depends on which kind of curve you are fitting, even if it were not pixelated. Curve fitting algorithms use a special curve (called a spline). The curve y = x^4 can never be fit by any finite number of splines.
If the images are not too big (otherwise work with smaller groups), and if the file names in both sets are ordered the same way, using scripts that exist:
Load N images of the first group as layers in one single image (open the first normally, and use File>Open as layers for the rest (the file selector in open-as-layers lets you select multiple files, so ...
