Bootskin Tutorial

How to make a Bootskin

In this tutorial you will learn how to create a bootskin step-by-step. In this example I’m using actual screenshots of the process of making a Bootskin of my own called Genesis Aftermath I.

A. Introduction:

Basic tools:

- MS Windows: Preferably Win XP is the right system to work on for Bootskin.
Microsoft Website: Link

- Bootskin: The actual program to create and apply Bootskins with ease and safety.
Bootskin Website: Link

- Photoshop CS (either full or free trial version): This is where the main work is done.
Adobe Website: Link

- WinZip: The utility to zip your Bootskins.
WinZip Website: Link

- Notepad or Object Edit or any other text editor: Used to make the little script that comes with every Bootskin. (Notepad is intergraded to Windows so you don’t need to download anything else).

The big picture:

To create a Bootskin you need to make-create three basic things:

a. The screen image: The actual image to show.
b. The progress bar: The tiny little bar that floats.
c. The script: A small text file that tells everything what to do.

B. The screen image:

- We will now attempt to make the screen image we want to use for our Bootskin. The whole process will take place in Adobe Photoshop CS. All terms referred are from the actual Photoshop layout.

- Screen image’s Properties: 640x480, 4-bit, 16 colors palette.

1. You need to make your image in 640x480, the resolution that any Bootskin screen image is. So if you have a bigger sized picture-wall you need to drop its resolution to 640x480. Appropriate wall sizes are: 800x600, 1024x768, 1280x960 and 1600x1200. If you have any other resolution you may need to do some clipping or stretch the image.

2. The way to do proper image resize is from the menu "Image>Size…" Upon click on it a Dialog Box will appear.

3. Tick all the check-boxes that appear on the lower part of the Dialog Box. Those are:
- Scale Styles (if you have a multilayered image and you used styles or blending options
on them to scale them as vector forms, gives them a cleaner look)
- Constrain Proportions (so that your image doesn’t get hindered too much)
- Resample Image (the mode to resample your image). In the drop down menu next to
Resample Image select Bicubic; this is the best method to bring down an image.

4. Now at the text box labeled as Width insert the number 640. With Constrain Proportions activated the Height should adjust automatically to 480. Press Ok to resize.

5. If your image is not of the resolutions mentioned above, then don’t click on Constrain Proportions and in the text boxed labeled as Width and Height insert the numbers 640 and 480 correspondingly. Press ok to resize. Note: This might alter image quality, but that is your choice.

Screenshot 1: In this first screenshot you can see steps 1-5:

6. Now you have the right size of image. The next you need to do is reduce the colors to the 4-bit palette or 16 colors.

7. The way to properly reduce the image color depth is to go from "Image>Mode>Indexed Color…" Indexing an image means that you’ll reduce its colors to a specified number and all pixels will be accordingly adjusted. The largest possible palette when you Index an image is consisted of 256 colors. Note: Imagine the image palette as a big matrix of boxes each one representing a color of the image. Each box has a unique value. The first color in the palette is called the Master Color. (Note this for future reference, since it’ll help you understand the relation between Screen Image and Progress Bar)

8. A property window will open. At this stage you’ll need to play a bit with all the fields. Check the check-box called Preview in order to preview the changes to your image and in that way you may experiment freely. The following fields are the ones that appear in the window with short explanatory tips:
- Palette: The way the color will be applied to the image. You may select from three kinds which are: Local (Selective), Local (Perspective), Local (Adaptive). You choose the one that is best for your image. I recommend using mostly Local (Selective) or Local (Perspective) since they map colors better.
- Colors: The number of colors you want the image to be indexed in. Here you just type the number 16, since this is the value for 4-bit images.
- Forced: The number of colors forced to be as default first colors in the palette. Here I recommend choosing Black & White, since these are the primary colors needed for the picture. (If you are an advanced user you may choose None or Custom).
- There is a check-box called Transparency. Do not check it, as it’ll ruin your work. The Windows system doesn’t recognize Transparency for system images, basically there is no transparency for 4-bit images at all. It is a feature for 256 colors images and beyond.
- The Matte drop-down list may be active or inactive, I don’t know what it is supposed to do, but you’d better not touch it and leave it as is.
- Dither: It has four different methods to dither the image. You may play with them freely and adjust it to your image needs. I recommend dithering with Diffusion.
- Amount: The amount of the applied dithering method. Usually is only active for Diffusion. I recommend setting it to about 85-95% for Diffusion.
- Also there is a check-box at the lower part of the Dialog Box labeled "Preserve Exact Colors". Do not check this as it’ll also ruin your work. Preserving colors is only possible for 256 colors or above images.
- After you bring the image to your liking Press Ok to apply changes. Note: Not all images look good in 16 colors. See the tips area below for more info as to the selection of images.

Screenshot 2: In this screenshot you can see steps 6-8:

9. Now you’ll need to save the images palette as you’ll need it to make a matching progress bar.

10. To save your image’s palette file go to "Image>Mode>Color Table…"

11. A property windows will open. In front of you is the palette of your image. Press Save and save the palette somewhere in your drive. Note: You may notice that the palettes are saved as .atn or .act (depends on your Photoshop’s Edition), those are action files, a collection of macros to perform various actions in Photoshop.

Screenshot 3: In this screenshot you can see steps 9-11:

12. Now you need to save the screen image. To do that go to File>Save As… and from the format drop-down list select .bmp. Give your image a name and hit the Save button. A properties window will come up. From that select 4-bit (don’t leave the default 8-bit value) and don’t select any of the boxes below.

Screenshot 4: In this screenshot you can see step 12:

C. The progress bar:

- We will now attempt to make the progress bar image we want to use for our Bootskin. The whole process will take place in Adobe Photoshop CS. All terms referred are from the actual Photoshop layout.

- Screen image’s Properties: 22x9, 4-bit, 16 colors palette.

1. You need to make your image in 22x9, the resolution that any Bootskin proper progress bar image is.

2. Paint the progress bar black with the bucket tool and reduce the colors to the 4-bit palette or 16 colors.

3. The way to properly reduce the image color depth is to go from "Image>Mode>Indexed Color…" Indexing an image means that you’ll reduce its colors to a specified number and all pixels will be accordingly adjusted. The largest possible palette when you Index an image is consisted of 256 colors. Note: Imagine the image palette as a big matrix of boxes each one representing a color of the image. Each box has a unique value. The first color in the palette is called the Master Color. (Note this for future reference, since it’ll help you understand the relation between Screen Image and Progress Bar)

4. A property window will open. At this stage you won’t need to play with any fields. Just leave them as they are and hit the ok button.

Screenshot 5: In this screenshot you can see steps 1-4:

5. Now you need to have the progress bar with the same kind of palette you used with your screen image. That is why you saved your original images palette.

6. To load your screen’s image palette go to "Image>Mode>Color Table…"

7. A property windows will open. In front of you is the palette of your image with only 2 or 3 colors. Press Load and find your screen image’s palette you previously saved somewhere in your drive and hit ok. Now you’ll see that you have the identical palette as your screen image. Note: You may notice that the palettes are saved as .atn or .act (depends on your Photoshop’s Edition, those are action files, a collection of macros to perform various actions in Photoshop.

Screenshot 6: In this screenshot you can see steps 5-7:

8. Time to move on to the actual progress image processing. First you open your screen image to use as a color chooser. It is the best, safest and fastest way since you don’t know the exact values of colors from your Color Table.

9. Pick color chooser and start picking the colors you’ll need for the progress bar image. Using the pencil tool draw your progress bar at any kind of design you like. For your convenience you may want to zoom to 1600% to be more precise as the progress bar is a very small image.

Screenshot 7: In this screenshot you can see steps 8-9:

10. Now you need to save the progress bar image. To do that go to File>Save As… and from the format drop-down list select .bmp. Give your image a name and hit the Save button. A properties window will come up. From that select 4-bit (don’t leave the default 8-bit value) and don’t select any of the boxes below. It is suggested to save the progress bar image in the same directory with the screen image.

Screenshot 8: In this screenshot you can see step 10:

D. The script:

- We will now attempt to make the script we want to use for our Bootskin. The whole process will take place in Notepad or Object Edit and MS Paint.

- Script’s Properties: File type of .ini.

1. The actual script is very simple. It consists of ten lines of properties code.

2. You open Notepad or Object Edit and write down the following code or copy/paste it exactly as given:

[BootSkin]
Type=
Name= ""
Author= ""
Description= ""
Screen=
ProgressBar=
ProgressBarX=
ProgressBarY=
ProgressBarWidth=

3. Explanatory guide for each field:

- [Bootskin] : This indicates for which program is the code for.
- Type= : I’m not sure what is the use for this. But the value is always 0.
- Name= "" : Within the quotation marks you put the name of your skin.
- Author= "" : Within the quotation marks you put the name of the creator/your name.
- Description= "" : Within the quotation marks you write down a brief description for your skin.
- Screen= : This is where you write down your screen image’s filename.
- ProgressBar= : This is where you write down your progress bar image’s filename.
- ProgressBarX= : The x-value where the right top angle of your progress bar image’s will be placed. This is a value that tells at which x-pixel of the screen image will the progress bar be placed. Note: x-y are used as in a graphical histogram.
- ProgressBarY = : The y-value where the right top angle of your progress bar image’s will be placed. This is a value that tells at which y-pixel of the screen image will the progress bar be placed. Note: x-y are used as in a graphical histogram.
- ProgressBarWidth = : The width that you wish your progress bar to be. Note: This is not the progress bar image’s width (22 pixels) but the distance you want your progress bar image to travel within the picture.

4. Example of complete script for better understanding:

[BootSkin]
Type= 0
Name= "Genesis Aftermath"
Author= "Cyberworld"
Description= "At the dawn of the new light..."
Screen= Genesis Aftermath Screen.bmp
ProgressBar= Genesis Aftermath Progress Bar.bmp
ProgressBarX= 115
ProgressBarY= 436
ProgressBarWidth= 475

5. You might have some trouble figuring out the x/y values as well as the progress bar width. So the easiest way to resolve this is via MS Paint. Open both your screen and progress bar images. On your progress bar image hit Ctrl+A to select the whole image and then Ctrl+C to Copy the image to the clipboard. Now on your screen image hit Ctrl+V to paste the progress bar image within it. You’ll notice that the progress image floats within the screen image and you can move it all around the image. I recommend that you already zoom into the area where you’d like your progress bar to start from prior to pasting the progress bar image. Place your cursor just one pixel above the area selected and see at the lower right part of MS Paint a place where some numbers appear. Those are the mouse coordinates the exact x-y values you need for your script. After that use the selection tool to draw a rectangle starting from the x-value of your progress bar image and pull it to a satisfying progress bar width. Again at the lower right part of MS Paint another set of numbers will appear stating the width and height of your rectangle. The first one is the width and the actual progress bar width value you need for your script.

Screenshot 9: In this screenshot you can see step 5:

6. When the script is ready save it as "bootskin.ini" from Notepad or Object Edit in the same directory with your screen and progress bar images.

E. Compiling the Bootskin:

1. This is the less recommended way to compile a .bootskin, yet it is the fastest and up to now the most efficient for me. Go to the directory where your screen and progress images are, as well as your bootskin.ini and select them all. Using WinZip or any other zipper program zip the three files into one .zip file. After this just rename the .zip to .bootskin and double-click it. The .bootskin file will auto-install to your bootskin directory.

2. That’s all. Your bootskin is ready.

F. Special Notes:

1. The Progress Bar image must always roll on the first color of the Screen image’s color palette. Usually that color is black, so in full color images you might need to create a small tray for your progress bar to roll on. Suggested tray sizes are the following: 112x11, 134x11, 156x11, 112x13, 134x13 and 156x13. The general rule goes: (Progress Bar Width + 2) x (Progress Bar Height + 2 or 4).

DisturbedRealm thank you very much for the feedback...i've sent you an e-mail, but i'd like to know what solution did you find and what was the exact problem (so that i can update the tutorial with a note).

hi there! I finally figured it out...thanks for the turorial. If you know of a good log in screen creator could you please let me know? I have logon studio but I can't figure out how to remove all the lines so I can put up a whole image. Thanks again.

Morning Cyberworld!

I've sent you an email as well but figured I'd put the prob and solution in here as well.

The problem is that you cannot start out with a .bmp you must open up a .jpeg in order to make changes. With a .bmp you will not get the property box when you click on indexed color. I just messed around with diff pics till I figured it out. Again thanks much for the awesome tutorial!!

Cyberworld.. a bit of a question... do you really need to use MS paint? seems you only used it to find the X,Y's for the progress bar...

D. The script:

5. You might have some trouble figuring out the x/y values as well as the progress bar width. So the easiest way to resolve this is via MS Paint. Open both your screen and progress bar images. On your progress bar image hit Ctrl+A to select the whole image and then Ctrl+C to Copy the image to the clipboard. Now on your screen image hit Ctrl+V to paste the progress bar image within it. You’ll notice that the progress image floats within the screen image and you can move it all around the image. I recommend that you already zoom into the area where you’d like your progress bar to start from prior to pasting the progress bar image. Place your cursor just one pixel above the area selected and see at the lower right part of MS Paint a place where some numbers appear. Those are the mouse coordinates the exact x-y values you need for your script. After that use the selection tool to draw a rectangle starting from the x-value of your progress bar image and pull it to a satisfying progress bar width. Again at the lower right part of MS Paint another set of numbers will appear stating the width and height of your rectangle. The first one is the width and the actual progress bar width value you need for your script.

Photoshop will show you the X,Y also in the Pallete that has the "Navigator" window, the tab "Info" will show you them and the width/hieght. You can also insert the progress bar image into the main image in PS and while holding Ctrl click on the progress bar image layer (highlighting it) and the same info tab will give you the same needed info.

My question is other than needing those values what do you use MS Paint for? Seems like an extra un-needed step to load that up and all. Just wondering...

Well SK i know about Photoshop and all and to tell you the truth i do use Photoshop for those values, but i find out that with MSPaint the process is more simple, also it is much easier for an average user. Also with Paint if you need to paint black some blocking pixels you can do it easy, while in Photoshop you'd need to re-save the pic in 4-bit. Basically it's not un un-needed step, it's a quicker process.

Ok, as I said just wondering

Wondering is good.

OK, I am having a problem with the final product of my bootscreen.... It is a simple bootscreen, and is correct format, and dimensions, and color depth and all that,
but is turning out all green and blurry looking... Here is a pic of the actual preview you see by hitting the preview button....

Link

But when I actually reboot my computer, it looks all green and wierd.... Any clue where I went wrong? Any advice would be appreciated!

Successfully updated karma reason!

Not sure about it...but i would suggest take a look at Bootskin program help files. I think it says something about some graphic cards not supporting or you may need a different version of the program. Alas i guess you've already check it out. So you can send me the actual .bootskin to take a peak at it. Contact via e-mail: nethphp@hotmail.com.

That is very likely that same old issue....the progress bar and main boot images do NOT have the same palette.

See if you can resize the boot image to become the progress image...and resave as...and try this new progress image with the original boot wall image....my bet is the 'green and weird' will go away...

Hi there i've seen your e-mail and will look into your problem in 20-25 days, i'm at excavations right now and don't have a regular PC to work with.

Glad you liked the tut.

The zip must be renemed from skinname.zip to skinname.bootskin.
You can also use bootskin to create the proper file, open bootskin, select skin in list, File, Export selected skin to file.

hey ive been making a bootskin and ive done all the instructions, and evrything seems fine accept when i restart windows and my bootscreen comes up about 1/5 of the screen image had been cut off the left of it and put onto the right can anyone help?

Successfully updated karma reason!

how do i make a zip into a bootskin file?

Successfully updated karma reason!

I use winrar.
You select files: bootskin.ini , Your picture boot.bmp (4bit), Progressbar.bmp(4bit)
This 3 files only.(jafo

)
and right click unzip with winrar select .zip (and not.rar) and you change the name of the archive like that:
"my boot.zip" to "my boot.bootskin"

very simply.
And if you want to included permissions select the "my boot.bootskin" and "permission.txt" and unzip (allways in .zip file and not in .rar)

hope that's help
