Inaddition to the image grid, GIMP also gives you a more flexible type of positioning aid: guides. These are horizontal or vertical lines you can temporarily display on an image while you are working on it.

You can create as many guides as you like, positioned wherever you like. To move a guide after you have created it, activate the Move tool in the Toolbox (or press the M key), you can then click and drag a guide; click-and-drag the intersection of two guides to move them together. To delete a guide, simply drag it outside the image. Holding down the Shift key, you can move everything but a guide, using the guides as an effective alignment aid.


If it makes things easier for you, you can change the default behavior for guides in the Image Windows Appearance page of the Preferences dialog. Disabling Show guides is probably a bad idea, though, for the reason just given.


GIMP comes with a built-in help system, available in dozens of languages. Onceyou have started the program, press F1 for context-sensitive help.You may have to install the help pages from a separate package (gimp-help),depending on how your version of GIMP was packaged.


3. Assuming all of the above is working correctly open one of the plane .psd files (you gotta extract it first from the .zip archive) in GIMP. You can also drop the .psd file into GIMP window to open it.


NOTE: Be aware of layer order, it is easy to get them in the wrong order then the weathering or something else may not appear properly. (new layers need to be lowered in the list generally or they appear on top of everything)


Now I'm going to go to 'Colors -> Hue-Saturation' and adjust the color of the Paint Fading effect and the layer opacity. Otherwise the winter paint effect will look too out of place on the green camo we are using. You can also adjust the layer mode, I'm going to leave it on hard light for berevity.


It should have saved your image. I always take this moment to undo twice in GIMP (CTRL+Z two times) so I don't accidentally save my flat dds file into my GIMP skin template and it is ready to edit if I don't like my work.


I am so incapable... I was wondering what the best way to change the yak's default green to a different color? For example, instead of green I would like two separate skins; one with white and one with grey like on the Shark skin.


Thx for the intro, but can you explain step by step how you drop the Polish emblem on the template, and how do you move it around? I tried and haven't got a clue, never skinned before, so absolute beginner!


* save function is for the gimp specific .xcf format that allows saving a skin file with multiple layers and all settings. You should always save your skin file and than export it as a .dds seperately to be able to have access to certain layers later on.


Not a real plugin but brushes can be very helpfull for camouflage / weathering effects. Just google "weathering brush" and how to install them (most brushes created for photoshop should work in gimp as well).


I've been using GIMP for a while now and have come to this understanding of layer use. Every layer has a Mode (found on the Layer tab just above the Opacity slider). Usually these are Normal, Overlay, Soft Light, or Multiply. As you are probably aware many layers are found in Layer Groups, indicated by a + or - sign to expand or contract the view of the individual layers inside the group. The ONLY layer mode that can be in a Layer Group is Normal. If layers with modes other than Normal are present in a layer group they will not effect the skin. Simply drag layers other than Normal to a just above the group they were in. Best solution I could come up with.


Has anyone tried the most current version of GIMP (GIMP 2.10.12)? I seem to be unable to use it to edit/modify files. Also, has anyone used Corel PaintShopPro as a photo editor? It seems to stomp the alpha mask when saving work. I am trying to make skins and only run into problems. Thanks in advance for any pointers or assistance.


I followed the instructions in post #1 and it works perfectly. But when I try to only use the OD (Olive Drab) base color it is so reflective that you can barely see the green color. How can I reduce the shiny reflectiveness a little bit? (I have exported without applying the Alpha Layer Channel Mask, but that seems to remove all of the reflection.)


[...] If for some reason you want precise dimensions for the sections,calculate using the DPI of the image to get linear measurements, anduse the Image > Guides > New Guide command to position guidesexactly where you want them.

One is to create a new layer in the image, sizing the new layer to 1024 x 1024 (or whatever size needed, I change the opacity of the layer to a low enough value to be able to see the layer below, and move the to just the place I want it. Then I select the whole layer, and using the layer dialog, change the active layer to the layer containing the material I want, and crop the image to selection. Then finally, I delete the layer I added.


The other is to use the rectangle selection tool, and select the area in the approximate area I from which I want to extract material. I use the adjustment parts of the rectangle tool to adjust the size, and while one is adjusting, the size of the rectangle is shown in pixels. Then I either crop the image to the selection size, or copy the part of the image I want to the clipboard, and create a new image from the clipboard.


But I'd still like to have a keyboard shortcut to create a guide. There are sufficient number of occasions when I know I want a guide at a specific place, and it would be quicker to press a few keys, than move the mouse around.


Sigh... You guys sure like to go the long way around... Both rectangleselect and crop tool have size constraints. In this case, grab croptool, set it to fixed size, set size to 1024x1024 and crop away. Withnice preview of what's in and what's out too...


I don't know of a way to do that but I have found that when setting guides it is so fast to zoom in to a fairly tight resolution with the CTRL-ScrollWheel combination then use the status area at the bottom to set it exactly where I want it, that snapping has never been something I looked for.


The main reason for zooming is just to give the mouse finer control if you are looking for an individual pixel. And since the tool changes to move, once you drag a guide on it is pretty quick even if you start at a fairly low display resolution.


Solution without explicit guides: several "Transform" tools (Scale, Shear, Rotate...) have built-in guides, and one of the option for these is "Center lines", so just start the Tool and just set the option (unless you need to know where the center is when using these tools).


Of course using real guides is often a good idea. If you find yourself routinely adding guides at the same place (center lines, for instance), have a look at ofn-preset-guides that lets you define your favorite guides sets and makes them available with a keyboard shortcut.


How about a semi-clever work-around?

Let your company standard-blue background

be the bottom layer (layer 0) in your Gimp Layer stack.

As layer 1, create a white layer which will be visible

when you place your images &c, using guidelines.


Is it possible to copy guide lines from one image to another?

I need this because I have several images that need exactly the same composition, so I want to use the guide lines for this.

There's no option to select & copy a guide line, so I must add them manually.


Having been wanting to learn Gimp Scripts (PythonFu) for a while and requiring this functionality I used the Pseudo code provided by MarkusQ and this handy tutorial -fu-gimp-scripting-tutorial-pages/ to create a script to copy guidelines from one image to another.


You'll need to copy this in to a CopyGuidelines.py file and put it your Gimp's plugin directory (See Preferences > Folders ) and restart Gimp to see the CopyGuideline option under Tools. Then open up the two images, select the one with the Guidelines and select CopyGuidelines to run the script.


I am having a problem with GIMP under XFCE (tried this under OpenBox and Windowlab, and did not have the same problem). When I try to drag a guide from the ruler, no guide appears on the canvas, and GIMP and some other applications stop accepting mouse input ... I'm not entirely clear on the extent of the problem: the mouse stops working entirely within GIMP, and I can't bring up a root menu on the desktop either. On the other hand, the mouse works normally within Firefox, and I can still perform window manager operations (including dragging, resizing, and closing) using the title bar and borders of GIMP windows. An additional twist is that GIMP still accepts keyboard input, so for example I can display the Layers dialog with Control+L ... but when I do that, it becomes impossible to drag GIMP windows on the screen, and I can no longer type commands in a [XFCE] virtual terminal--though Firefox is still unaffected.
