As for channels... well, a channel is an element of an image, basically. Each layer is composed of 4 channels: Red, Green, Blue and Alpha. Furthermore, you can extract other channels from the coloured ones mathematically: Hue, Value, Lightness, Saturation... CMYK are also possible. Anyway...

You know how we have the "trace" layer in this image? It is basically a layer that stores a selection. We use it to reload that certain selection we made, whenever we need it again later in development, by using the Alpha to Selection function. In GIMP, the selection is also a channel, which is why it's easy to import from the Alpha channel of any layer.

So, channels provide another means of doing the same thing: instead of using a layer for saving a selection, we could store that selection into a channel and it would go to the channels tab. If you are making a map that has lots of selections that need to be saved and loaded later, then using channels is a good idea, because it keeps them separate from the layers.

In this tutorial we only need to save that one selection, so I took the simpler route and left channels out of this.

i'm going to read that a few times and i'm pretty sure i'll get what i need out of it.

i'm thinking that it means saving a shape that you may want to put different textures and colors on. or make copies of it. or maybe saving certain colors out of a shape to help with the textures and shadowing, i may be off there, but like i said, i'll read through it again, then do some tests, i should be able to handle it. there is just so much going on in gimp, but i already know more about it than i would have thought when i first cranked it up.

thanks for the help.

Ok...I got everything right up until steps 5 and 6. When I create the gradient overlay it never works out as it should...and instead produces a large gray and white spherical figure over the map. Then I create the land textures tab...do all that...on the final form, it shows the outlines of the bonuses, but none of it is colored, and the background is the gray/white spherical object instead of the sea.

Any thoughts on this?

did you set the mode on soft light and 50% opacity?

You have to change the layer mode of both layers. It says so right there on the tutorial.

Yes, and I still get the same thing.

Edit: I went back in and tried it again. I have all the settings correct...radial, soft light, ~40% opacity. I still get the same thing. I went ahead and did the texture layer just out of curiosity. Moved the texture layer below the bonus border layer, and still I get colorless bonuses with a gray/white sphere in the background. I removed the gradient overlay layer, and I get colorless bonus areas on a blue sea background. So I'm having problems with both the gradient overlay and the texture layer. And I'm pretty certain that I did all the settings exactly how it says to in the tutorial. Any thoughts?

Make sure the layers are in the right order. Make sure the layer mode of both the gradient overlay and texture layers are set to "soft light", not "hard light". And the opacity of the gradient overlay layer should be set to 50.

What version of GIMP are you using?

All the layers are in the correct order. Both of those are set to soft light. I had the opacity a bit lower than that...but I will try moving it to 50%.

Also, version 2.6.11.

Edit: Ok, I got the gradient overlay to work, I think. I tried it again, this time with those settings picked before using the blend tool, instead of waiting until after I had used the tool to set it at soft light and 50%. I say I think it worked, because I didn't get the ugly gray/white sphere, but still, it doesn't look like anything happened really.

Then I went on to the texture...and the same thing happens. I do it exactly like you describe, but still I end up with gray/colorless land/bonuses and blue water. I've got my bonus borders on the map and everything, but there is no color to them. You said to move the Land Texture layer below the Bonus Border layer, which I did. Should it go below all the different Bonus Layers as well? I can't really think of anything else here...

I can't really think of what could be the problem here. Can you upload your .XCF file somewhere and post the link so I can take a look at it?

Fileden is one file hosting site you can use, you need to create an account there but it's free.

I'm just waiting on Fileden to send me the email so I can activate my account. Then I'll post the link. I'm going to upload a save where I've done up to step 6, so you can see what I've done wrong or whatever.

Ok Natty....here is the link.

Ok... neither layer is set on soft light. They're both in normal mode.

I think you may have changed the blend mode of the paint tool instead of the layer blend mode. The layer mode is changed from the layer window, where the layers are, not from the toolbox. Same with layer opacity.

Here, I set the layers for you. I set the gradient layer on hard light because your colours are so bright, soft light doesn't show well on them... You might want to decrease the saturation of your colours somewhat. And make the ocean a bit darker maybe.

Find the layer mode & layer opacity settings in the layer window, then you can play with the layer modes yourself... layer modes are one of the most powerful features of GIMP, you can do all kinds of neat stuff with them.

I'll elaborate a bit on the difference of the paint tool blend mode (in the tool box, in the tool options of many tools, like paintbrush, fill, blend, etc. ) and the layer blend mode (or layer mode in short, which is in the layers window, in the layer options). The paint tool mode affects the blend mode of what you paint, interactively. So what you paint on the current layer is blended on it using the blend mode you select. Whereas, the layer mode affects the whole layer, regardless of what mode was used to paint on it, and it, unlike the paint mode, can always be changed later.

Ahhh...

Of course it would be something simple like that. Thanks a lot for the help. I had absolutely no idea about setting it in the layer, and not the tool. And I will work on the colors a bit, see what I can do with them.

Again, thanks a lot. I appreciate that...it saved me tons of time going through just messing with stuff to figure it out.

Hi, I just started using this, and I know this is probaly a stupid question, but after I import the image to trace, scale it, how do I view the whole image? All I can see of my image is one small section that I can move, and the rest is all grey around it. Thanks

The problem is that you've made a new empty image, then pasted a larger image on that new image.

What you need to do is select "paste as new image" or ctrl-shift-v instead of ctrl-v and a new image will automatically be created with the right dimensions, with the image you pasted as the first layer.

question, what to do when i save? merge layers?

Don't do that.

If you want to save the file for further editing, just save it in the native .xcf format so the layers etc. will stay intact. So you can continue editing the file later.

If you want to export the image to a regular image file that you can upload on the web, save a copy of the image (file > save a copy) and then save it as a .PNG or .JPG file. Layers will not be preserved in these file formats, so you can't use them for editing the image later.

"You can download...into XCF format."

I guess that's my starting problem. I can't get off the ground without this format. I don't want to use Denmark...I'd like to make a different map. How do I get to that first, most basic point?

Practise is the best thing.

But to answer you better, find a picture you want to copy and open it in gimp. Make a new layer on the top and use that to start your drawing. Follow nattys guide, it is basic, very basic but it gives you all of the points you will need to get a starting image. You save your file in xcf format so you keep your layers and then save again as PNG or jpeg. This will merge the layers into one which you can put onto the web for us to see.

Follow the 2 guides and you will get an image that you can use. It is then up to you to go that next step.

natty, when is part 2b coming?

I think the next tutorial I write will not be a continuation to these ones, it will be a new one that will describe more advanced graphical techniques, rather than basic ones like these. I have no idea when I'll have time to write it though...

It will however probably be only after 2.8 has come out and it will be written for 2.8.

Several times you say something like, "A window like X will open." I never had that window open. For instance, "Colors-->Hue." Never can get it to open.

If you select Hue/Saturation from the Colour menu, a dialog window will open. You need to have a layer selected for the tool to work.

Either GIMP is beyond me, or I have a different GIMP, or there's some other subtle user error. I'm giving this up. 8 hours and I can't get past the first tutorial lol. Not worth it; I guess I'll just have to enjoy the maps someone else makes. My hand-drawn maps look better than my GIMP attempts!

is there a way to key in coordinates instead of trying to click right on them. like can i key in coordinates for a box, then use the stroke selection key to connect the dots?

for example; i want a box that is 40 pixels high and 500 pixels wide. can i just key in the corners and somehow connect them with line instead of tediously trying to click right on the exact points. ( which i find very exasperating )

does this make sense.
