To expand on utopicam's answer, sometimes your image might contain areas, such as shadows, that you'd want to be semitransparent. For example, let's say you have a photo shot in a lightbox, such as this nice and freely licensed picture of a Swedish wooden toy horse courtesy of Creative Tools:
In general, the first step would be to adjust the levels of the ...
If you imported a GIF file into GIMP, your problem is that your image is in indexed mode.
In this mode, most filters and color tools won't work, and be grayed out (up to GIMP 2.8 - expect news on this front on GIMP 2.10).
So, all you have to do there is to go to Image->Mode->RGB, and the Color to alpha menu entry will be enabled.
I don't think that ...
Using fast bucket fill instead of contour selection
Note: This tutorial is also available in PDF.
Add an alpha channel
Some image types lack a transparency channel; JPG for example. If this is the case, add an alpha transparency channel.
This is done by selecting Layer → Tranparency → Add Alpha Channel.
Bucket fill with colour [optional]
The next step ...
Looks like your move tool is in 'Move selection' mode. Check the Move setting in the tool options (this image is from the docs and shows Move layer mode):
The Alt key toggles to the 'Move selection' mode (Ctrl does the same for 'Move path'), and is supposed to switch back to 'Move layer' once you let go of the key. If you manage to steal the input focus ...
GIMP's Color to Alpha tool is very handy if you know how to use it, and this task seems particularly well suited for it:
Open the image in GIMP, and change it to RGB color mode if necessary.
Select Layer → Transparency → Color to Alpha...
Select black (#000000) as the color to make transparent.
Save the resulting image in PNG format:
Are you sure you're clicking on the actual letters in the text? When selecting a layer to move, GIMP will pick the uppermost layer which is non-transparent1 at the point you clicked, ignoring any transparent layers that might be on top of it.
What this means is that, using the "Pick a layer or guide" mode of the move tool, you can only drag a layer around ...
To answer your literal question, there are a few areas where GIMP can be better than Photoshop. It's not particularly common (usually, at best you can expect them to do the job equally well), but it does happen. Off the top of my head (and keeping in mind that it's been many years since I last used Photoshop), here are a few examples:
As a historical ...
We can easily slice an image to subimages along predefined guides using the Guillotine tool:
Define Image > Guides > New Guides (by Percent) at 25% 50% 75% horizontal and vertical resp.
Apply Image > Slice using Guides (in Gimp 2.8. Image > Transform > Guillotine) to slice into subimages:
To export the images in ready to use HTML code we can alternatively ...
Before I start, just to let you know I'm a happy and frequent user of GIMP, but I also have an Adobe CC account, and use the latest version of Photoshop, which I also enjoy using. I'm not a fanboy of anything.
GIMP is not Photoshop, and it doesn't really try to compete with Photoshop. It's not commercially developed, and so it's not a commercial competitor,...
It's not possible. The only thing you can do is link layers together or merge them. How to link layers information here.
Instead, there are several alternative methods of handling multiple layers, each appropriate to a different task. You can chain layers to move or transform them, shift-click objects on different layers in the canvas to align them, or ...
Whenever we choose to change a color to transparent with the Layer > Transparency> Color to alpha tool we will also introduce semi-transparency of colors different to the selected. Below this is shown for making white in the background transparent:
In case this is not wanted we need to select only a single colored area for transparency. This can be done ...
OK, so I assume you have two images: a normal image that you want to add transparency to, and a grayscale image that you want to use as its alpha (transparency) channel, something like these:
(Base image based on this photo by John Fielding, used under the CC-By-SA 2.0 license; alpha mask created by me using the GIMP's Sphere Designer tool.)
There are ...
The main trick, in my experience, to adding smooth transparency to an image in GIMP is using the Layer → Transparency → Color to Alpha... tool. Of course, you have to know how to use it to good effect — on its own, all it does is make your images look all funny and translucent.
If I take the image you posted above, and just run Color to ...
Your move tool is set to move the selection, not the area selected by.
Transform your selection to a float selection using Select->Float
In the move tool options choose to move Layer instead to Selection (by pressing the first icon near "Mover" in "Opciones de herramienta")
Now, it should be possible to move the shine.
You could use the "difference" layer mode to create a layer mask, and apply it to B like this:
Open both images as layers, A on the bottom, B on top
On the layer's dialog, mark B's layer mode as "difference". You now
should see the image mostly black is the images are alike, with the
colored areas marking the areas that are different. These colors,
I was looking for an answer to this, which is why I came upon this question. The closest solution I could find is this:
Click on the top ruler and drag down a guide to the Y coordinate you want.
Click on the left ruler and drag right a guide to the X coordinate you want.
Use the move tool to drag the layer to the approximate position you want it. It will ...
This is for GIMP
Start with something like an A5 canvas size
Create a new brush like this
Create a new Paint Dynamic preset, and set the matrix as follows
Increase the size of the brush as you like, and paint random coloured lines, choosing different colours, on a new transparent layer above a black background layer.
Continue until you've built up enough ...
Sounds like you need to crop certain parts of the jpgs (the main figure, for example) and delete the "background". You can do so using the lasso tool.
The gimp website has lots of tutorials and explanations. Check this http://docs.gimp.org/en/gimp-painting.html#gimp-concepts-selection and this out: http://docs.gimp.org/en/gimp-tool-free-select.html
This can be achieved by clicking "Colors" --> "Colorify..." (Not "Colorize...") That brings up a dialog box.
Click the color box next to "Custom color:" to enter HSV, RGB, Hex, or use a color picker.
Documentation for "Colorify" is available here: http://docs.gimp.org/en/plug-in-colorify.html
With Gimp comes a plugin Resynthesize together with a Python script Heal Selection. On Linux the plugin is contained in the package gimp-plugin-registry.
After selecting an area with the select tool:
We can "heal" this selection from "Filters > Enhance > Heal selection...". Here I made a random healing with 10 pixels from the surrounding:
If you have control over the scanning, or can get them rescanned, increase the contrast setting in the scan and set the black point at the darkest bit of text you can find. That would make the steps below easier. If not, read on...
Here's part of a fairly typical old document scan:
The details will be different depending on the document (this has somewhat ...
I had been having this problem FOREVER and I just found a solution, even though the person I was talking to about the move tool made me actually figure out the problem.
The alignment tool is selecting the top most layer where ever you click, regardless of what layer you have selected/transparencies. Try hiding the layers above what you are trying to work ...
There is a plugin:
Download arrow.scm and save it to /home/username/.gimp-2.8/scripts (on a Linux system).
Check your version numbers, naturally. Next time you start up Gimp, you should see an Arrow option under the Tools menu.
You could also convert the transparency into a layer mask using Layer → Mask → Add Layer Mask... and selecting the "Transfer layer's alpha channel" option.
This will let you edit the color and transparency components of the layer independently. In particular, to recolor an object, you can just select a region around it and fill it with a solid color.
In the tool options for the eraser:
Select the first brush (pixel).
Select a size of 1.
Select hard edge.
Set Dynamics to Dynamics off
Then the eraser should do what you want.
(Also, do not forget that you need an alpha channel on the respective layer.)
You can (from 2.8 on) make use of layer groups to get most of the functionality you might want:
From the GIMP docs:
You can create a layer group either by
Clicking on the Create a new layer group button at the bottom of the layer dialog (looks like a folder icon)
Through Layer → New Layer Group, or
To be sure..
Convert it to a real layer
Activate the move-tool
Choose "Move the active layer" in the settings panel for your tool
Activate/select your layer
Click once on the canvas
Depending on circumstances, you could skip different or all steps. But if done correctly, you should now be able to move your layer with your mouse or the arrow keys!
EDIT: If ...
Here's the answer you're most likely looking for:
Scenario: say in GIMP you have a logo image, you increase the Canvas, center the logo inside the enlarged canvas, and you want to fill the extra canvas with an eye-dropper color. However, the paint bucket shows a black circle with line through it indicating no-can-do.
Do this: from menu, select "Layer", ...
Copy&paste is the wrong approach to copy layers from one image to another - this will only transfer the layer content, and as you have discovered that isn't the same as a layer or group of layers.
Instead, drag the layer or layer group from the layers dialog of the source image to an image window of the target image. This will keep them intact, ...
