The Explorer window will open. The asset folder will open. Navigate to the location of the. The loco will appear in the viewer. Start Paint. The asset folder will appear. Find the main body TGA image and double click it It is also often called Main, or perhaps it has the same name as the loco.
The image will open in the window. The Paint. Net Save format is PDN — this will be used for saving your reskinning project so you can come back to it at any time. Make sure PDN is selected as the Save as type. Navigate to the working directory and the project folder that was created in step 1, and save the PDN file in the project folder.. If the Layers panel in Paint. Note that two layers are listed - Background and Layer 1. One of them will be highlighted. Click in the other layer to highlight that other layer.
The highlighted layer is the one on which all selecting or drawing will occur. Note that the layers also have a check box. This controls whether or not the layers are visible. Layer 1 is currently all transparent, so when you create and show this new layer, it doesn't seem like anything has changed. Click in Layer 1 in the Layers window to make it the active layer. Make sure it is also visible the tick box is ticked.
This setting ensures that detail such as weathering from the background layer is applied to the final image when the layers are merged for display.
With layer 1 active and both layers visible you should see the original image. Layer 1 is entirely transparent by default. Use the Mesh Viewer image to relate the portions of the skin image to the full model. Note that most of the mapping is obvious, but some parts are quite mysterious.
Some assets will have the different portions of the image labelled with what they are, which helps a lot. If the labels do not exist then you could consider adding labelling to your project. The labelling does not have to be on the image - it can be in a separate layer which you turn on and off as needed. This is the step where you see the benefits of working with layers. Select the rectangular selection tool top left in the toolbar.
Starting from a corner of a section of the loco that you want to change e. Select the Fill tool from the toolbox the pouring bucket.
Left-click inside the selected rectangle. It will fill with the selected color. Also notice how the coloring has retained the shading of detail from the background image.
Adjust the opacity setting to see the effect. This could be referred to as saturation. But note that the detail in the background image is retained even when opacity is This is the result of using a layer Blending Mode of Multiply: you can experiment with other blending modes to see the effects that are available.
Select a new color. With the Fill tool still selected, click anywhere within that colored patch. The color changes to the new color. By default, the fill tool fills only regions of the one color. This means that if you keep your colored regions separate then you can recolor any region simply by filling that region using the fill tool. Or, just select a region and hit Delete to remove all painting in that region.
The skin image is mostly laid out in separate rectangular regions that are mapped to distinct areas of the mesh body, so this is easy to do. Continue selecting and filling rectangular areas in layer 1 until you have colored the loco like you want. Remember that you can set up additional layers as required - this would be very useful where areas overlap, but you want to continue to handle them separately probably not relevant for locos, but could apply to other asset types.
With the default PDN file type, save your work in the project folder. This saves your project, so you can get back to where you were at any time in the future. Click OK to overwrite. This will save the image, which is what is used for the reskinning. You must flatten the layers to save as TGA, so select Flatten. The file will be saved. You must unflatten the layers immediately after saving as TGA in order to be able to continue to work on the layers separately.
Also, click in the layer 1 item in the layers window, as the default working layer will have changed from Layer 1 to Background, and you will probably continue your work in Layer 1 or any other layer you added rather than the background.
If you forget to unflatten the layers you will need to go back to the project folder and re-load the PDN, possibly losing some work. You will save as TGA in the Edit folder when you want to see your results. They must not be preferred over your local address-book. As I stated, they are one of the new developments in Gnutella, and thus I will now get to some more of the recent changes within Gnutella and to future plans.
You'll surely have friends who know very many other people, and whom you can ask, and be sure they'll know exactly the person who can give you the answer. These are called Ultrapeers in Gnutella. In Gnutella that means that a good Ultrapeer doesn't need to have many files to benefit the network. If you're afraid to share much, you should become an Ultrapeer in Gnutella.
In the Computer World, as in the Real World, there are contacts who can cope with more calls, and those who can't phone often or can't afford the bills.
In the Real World this is because they have more free time. Upon realizing this, the developers decided to change the topology, that means how the network looks from the outside when you draw it. Now you don't just call any of your friends, but only those whom you know have the time to take your call and to send it on to others. To save you from too many calls, they then ask you which kinds of informations you have or, to express it in a more human way, what your specialty is. In the Computer World that means your computer sends a list of all its files to the Ultrapeer, which is how we call these kinds of contacts.
That list contains summaries Hash-Strings of all your shared files those you decide to let others download by which the downloader can verify that they are, indeed, the files he or she wants. Whenever a call reaches the Ultrapeer, it checks if you could know an answer and calls you only in that case. These Ultrapeers have many connections to others, which means they have a really big address book. Normally they stay in contact with 16 other Ultrapeers whom they have in their address book and to whom they send questions, and who send them to 16 more, each.
Also they have about 16 leafs, who can't or don't want to phone that much, from which they accept calls, and whose files or, for the human world, specialties they know. This may seem like a foul bargain for the Ultrapeers, who devote far more resources to keeping the network intact than leafs, but in fact it isn't. While the Ultrapeer UP uses much of her time for keeping the network running, the leafs specialize on gathering and delivering information. So, when anyone, Ultrapeer or Leaf, wants to know something, he or she simply starts a call and a leaf specialist can explain it to them.
That way people specialize to get more for all. While with Ultrapeers not everyone needs to participate in sending questions to others, and people can specialize in sharing their information instead, the Ultrapeers would still send every question to everyone, without ever taking into account if that UP even has leaves, who have the files. This sounds normal, for how can an Ultrapeer know which files the other Ultrapeers have? The answer comes, again, from real life.
A normal person knows her friends, and knows who of them might know the answer to a specific question, and who most surely will not. In Real Life this is mostly done through friendly chatting. Now, computers normally don't chat idly, so they don't exchange this information by the way. Thus the Query Routing Protocol was developed. There each Leaf tells its Ultrapeers which files it has, but instead of taking the names, which would consume too much space, each word which is part of the name of a file is saved as numbers these are computers after all.
You can imagine this process like a game of BattleShips the numbers form the board with two coordinates. An Ultrapeer doesn't send all questions to a leaf, but only those which it might be able to answer which hit a ship , and so Leafs get far less needless calls. Now when this takes so much pressure off the leaves, why not extend it?
Exactly that was done. Now all Ultrapeers send their boards to their direct neighbors. They send only those searches, which have one more step to go, to other Ultrapeers on whose board they score a hit.
That means, the last two steps of a search will only be taken when there is a chance that they give results. You can see quite simply why this heavily reduces the bandwidth usage: imagine a tree, a normal tree, not one of those mathematical constructs.
If you try to count the leaves, you have almost no chance. But if you take the leaves away and count only the branches, you have far less work to do. If you now take away all those tiny branches, you can really begin to count them. QRP doesn't take all leaves and all tiny branches away, but it removes those of them who couldn't give you an answer. Since every part through which a question has to travel consumes bandwidth, and there are far more leaves than branches, taking away, in many cases, many of the last two steps that means many of the leaves and the tiny branches reduces the number of questions the computers have to send on there are far more leaves, than branches.
The example doesn't work for all of Gnutella, but here it fits nicely. Now, while the Ultrapeer model and QRP partly solve the problem that you don't have the time to explain something properly to someone else, or to get it explained, because the phone rings endlessly for questions to which you know no answer or in Tech-Speech: because the network-traffic exceeds your connection-speed , there is still another problem which might normally not even be visible, if you look at it.
In the Computer-World, the question is sent on and on, to as many contacts as possible, without looking if there already are answers. With dynamic Querying that changes. Now the Ultrapeers ask one other Ultrapeer at a time, and wait a bit, to see if they get answers. When they have enough answers to be satisfied, they stop asking for more. It sounds pretty natural, but was quite a big step for Gnutella because it saves resources which were wasted on very popular questions.
Pertinent, but without visibility on libkiwix emscripten, I assume this won't happen soon. Yes, but all of this seems a problem easier to fix than the technical ones. In worse case we can make another project with another name to avoid confusion.
This ticket requires it works out-of-the-box with ZIM files like they are today I have expressed clearly my point of view here: comment. Developers who don't believe it could work, I guess, are not going to implement it I understand this is now the hard part :.
But I've no idea how viable it is really, until the various pieces of the puzzle come together! Regarding the user experience, another way to handle that would be to hide this feature in the UI, and have a "secret" way to show it. This would allow to keep only one project, one source code, and one deployment.
In this case, I would see that as a "playground" feature for now, that is not ready for end-users, and could be removed in the future either because it's not viable, or because the switch to libzim breaks it. NB : I won't have time to work on that myself. If I find some time, I'll work on the libzim emscripten feature. Skip to content. Star New issue. Jump to bottom.
