I need read 10 byte in fileName and save it into bitLevel
My code:
PHP:
test = 0;
byte[] bitLevel = new byte[10];
string fileName = "levels\\";
switch(iChap){
case 1: fileName += "beginner.dat";
break;
case 2: fileName += "normal.dat";
break;
case 3: fileName += "intermediate.dat";
break;
case 4: fileName += "expert.dat";
break;
}
using(FileStream fileStream = new FileStream(fileName, FileMode.Open, FileAccess.Read))
{
fileStream.Seek((iLevel - 1) * 10, SeekOrigin.Begin);
fileStream.Read(bitLevel, 0,10);
test = 1;
}
but bitLevel is empty
It seem it's not into codes under using, because I set test = 1; but it = 0;
can anybody help me?
//sorry my bad english
Use IsolatedStorageFile & IsolatedStorageFileStream instead of FileStream.
sensboston said:
Use IsolatedStorageFile & IsolatedStorageFileStream instead of FileStream.
Click to expand...
Click to collapse
is that ok?
can you show me demo code?
Code:
using (IsolatedStorageFile isf = IsolatedStorageFile.GetUserStoreForApplication())
try
{
using (IsolatedStorageFileStream inStream = new IsolatedStorageFileStream(fileName, FileMode.Open, isf))
{
byte[] buffer = new byte[10];
int numRead = inStream.Read(buffer, 0, 10);
Debug.Assert (numRead == 10);
}
}
catch (Exception e)
{
Debug.WriteLine(e.Message + "\n" + e.StackTrace);
}
But this code for ISF only; I don't really know where are your files located (as resources or may be content). You should understand what are you trying to read first
If you added these files as a content to your project, you should read 'em from the TitleContainer
Code:
using (var inStream = TitleContainer.OpenStream(fileName))
using (StreamReader streamReader = new StreamReader(inStream))
... and so on...
This is a program that I wrote to decode the newer style "logo.bin" files used in some OPPO, and OnePlus devices. Please read below so you can better understand this type of encoding being used:
What Is A Raw Image?
A raw image, whether it be a file or an image in memory, is simply pixel data. There is no extra information like width, height, name, end of line... Absolutely nothing, just pixel data. If you have an image that is raw and the resolution is 1080x1920 and you are using a typical RGB24 or BGR24 (like the ones used here), then your exact filesize or size in memory will be 1080x1920x3! We use 3 here because there is one byte for the R or red component, one for the G (green), and one for the B(blue).
What Is A Run Length Encoded Image?
A run length image encoding uses a count ;usually a single byte (char), 2 bytes (short int), or 4 bytes (long int); and then the pixel components. So instead of writing out 300 bytes of '0's to make a line of 100 black pixels. Black is RGB(0,0,0). You could encode this as 100, 0, 0, 0. And only use 4 bytes of data to get the exact same image as the 300 byte raw image. All the run length encoding I've found, except the Motorola style which is a little different, use a run length encoding that is pixel-oriented like this.
Now I've figured out this new one and it is a byte-oriented run length encoding. This is for runs of bytes, not pixels. You may think, well whats the big deal? When you add a little area of color, you increase the run length encoded image in you logo.bin immensely! You use 6 bytes per pixel if there aren't any runs of color data. If you had an image that was a 1080x1920 black image with a 25 pixel wide, by 25 pixel high red box in the middle. The encoder would be doing runs of black data efficiently until it reached the red area.
.....0 255 0 255 0 255 0 255 0 255 0 99 /// we've reached the top left corner of the red square /// 13 1 30 1 255 1 // << that was just one red pixel!! in bgr color order (13, 30, 255) <<// And it keeps going through the rest of the red pixels on that line using 6 bytes per pixel, which is the opposite of compression. Before reaching the red square the encoding was decoding to 255 zeros over and over, until finally 99 zeros. 255 zeros is 85 black pixels stored in just 2 bytes!
This type of encoding is only good for grey scale images. It is not good with color, but it still will handle color of course. In grey scale, the Red, Blue, and Green data components are always the same values. All the way from black (0,0,0) to white (255, 255, 255); including every shade of grey in between>>>(1,1,1) (2,2,2) (3,3,3)....(253, 253, 253) (254, 254, 254)<<<
One other difference in this method of run length encoding is that the color byte is before the count, which is backwards from all of the other methods.
The attachment contains the C source code (which is also in the 2nd post) and the executable that was compiled using mingw32 on a 64 bit Windows 7 PC. The PNG library that I used is LodePng, the source is in the download.
To use logoinjector:
Decode your logo.bin:
Code:
logoInjector.exe -i logo.bin -d
All the PNG 's will be extracted from logo.bin. Edit the PNGs that you want to change...
Note:
Your original "logo.bin" file is never changed, it is just read. If the file you try to load isn't a logo.bin file, or if it is the older style, then the program will tell you and exit
Inject the image(s) back in to the logo.bin:
Code:
logoinjector.exe -i logo.bin -j image_name_1 image_name_3....
To list whats in your logo file:
Code:
logoinjector.exe -i logo.bin -l
For a more detailed list:
Code:
logoinjector.exe -i logo.bin -L
If the colors are messed up use the "-s" switch while decoding.
Code:
logoinjector.exe -i logo.bin -d -s
If you had to use the "-s" switch to decode properly, you'll have to use it to inject also:
Code:
logoinjector.exe -i logo.bin -j image_name -s
Note:
With version 1.2, you can put as many names after "-j" as you want, and it's not case sensitive. You also don't have to put the whole name. If you just put "-j fhd" every image in the logo.bin that starts with "fhd" will be injected. There has to be a PNG with the name in the directory though
The size of your modified.logo.bin will displayed along with the original size, if everything went good. Please know the size of you logo partition. I made this program to encompass any device using this format, and there is no set size of the logo partition between devices. Fastboot will just error out if you try to flash data bigger than the partition before it writes anything. But if someone gets brave and tries to "DD" to the logo partition, it could get ugly.:cyclops:
Flash the "modified.logo.bin" file through fastboot.
v1.2
made it possible for multiple injections in one command
doesn't add png to the decoded png if it was already in the name
fixed out of scope with image 26 in OPPO find 7 logo.bin
added LodePng source in the download
made the default color order BGR
displays the modified logo file size as well as the original file size
runs the modified.logo.bin back through the list function after injecting
checks the number of offsets between the original and modified logo.bin
Use this at your own risk.
Always make backups.
Always.

Interesting Can you tell me where do I find the logo.bin in my boot.img. I've extracted mine and don't see any sign of logo.bin. I own a OnePlus 2

Did you download a system image? If so, unzip it, and look for the folder "firmware-update". The logo.bin should be in there.
Works well for me! Thanks!

Thanks!! Removed this:
This is untested on the oneplus 2, however I've looked at the logo.bin from your firmware and it is identical to the newer oneplus one logo.bin. Let me know! Thanks!

how did you flash your modified logo.bin? if done through "fastboot flash logo logo.bin" it just quits with this error:
Code:
target reported max download size of 536870912 bytes
sending 'logo' (1581 KB)...

this also happens with an unmodified logo.bin

You have to flash "LOGO" partition and not "logo"

gotta love case sensitivity. thanks, it worked.
awesome mod
It worked, thanks
This will work with Stock Oneplus 2 rom too, right?
Edit:
Working fine with my Onelus2 too, just got logo.bin from my stock Oxygen rom. Thanks again.
From where can I extract my logo.bin from my phone? I dont have the stock rom with me. I need this from 1+2 if this works with it?

I went into changing the splash screen only after I'd already changed to custom rom ( bliss 6 ), so I didn't had any official OPT rom zip.
I tried to use the "logo.bin.p" from latest OTA updates FROM HERE... but the LogoInjector telling me that "This is NOT a valid Logo.bin".
Solution I found -> I managed to EXTRACT THE LOGO.BIN FILE FROM THE OPT ITSELF !!!
I got it right after I read about this command and saw the "updater-script" from one of the official OTA updates that included a hint about logo.bin place in the OPT internal storage :
apply_patch("EMMC:/dev/block/bootdevice/by-name/LOGO:305152:567b5d4deed7f4875809ae8b7f071ab38e5a94d5:305152:16c76f9c0cadf8be18eed0961dfbcf3b7bd0aacf",
"-", 16c76f9c0cadf8be18eed0961dfbcf3b7bd0aacf, 305152,
567b5d4deed7f4875809ae8b7f071ab38e5a94d5, package_extract_file("patch/firmware-update/logo.bin.p"));
Click to expand...
Click to collapse
so... how to extract to logo.bin ?
Note: If you don't know what you're doing - DO NOT DO IT ! DD command is DANGEROUS !
Using adb open shell and run the following command:
dd if=/dev/block/bootdevice/by-name/LOGO of=/sdcard/logo.bin bs=305152 count=1
Click to expand...
Click to collapse
This will create a "logo.bin" file inside the root of your internal memory aka /sdcard folder.
I got from that the following image files list:
Resolution - Offset - Name
1080x1920 | 0............ | fhd_oppo_1080_1920_result.raw ---> THE SPLASH IMAGE !!!
536x60.........| 65536 | fhd_at_536_60_result.raw
300x1020....| 75264 | fhd_charger_300_1020_result.raw
1080x1920 | 89600 | fhd_fastboot_1080_1920_result.raw ---> THE FASTBOOT IMAGE !!!
1080x1920 | 145920 | fhd_lowpower_1080_1920_result.raw
392x66 ........| 277504 | fhd_rf_392_66_result.raw
487x69 ........| 285184 | fhd_wlan_487_69_result.raw
Note, inorder to load the png to the logo.bin you need to rename the png you make as *.raw according to this list above.
Now... inorder to "flash" the logo.bin back to the OPT I use the attached zip.
you only need to add "logo.bin" to the root of this zip, then flash it through TWRP.
@makers_mark - once again, after your OPO development - Thanks A LOT for developing & sharing with us LogoInjector for the OPT as well
@makers_mark
Could you make one for oneplus3?
Thanks in advance.
logo.bin for oneplus3 is attached.

whit ANDROID previous kitkat I was able to store an image on sd-card without problem, now, instead, I've a lot of difficult.
I can't understand how use a new Access Store Framework of Android Lollipop and I don't know if it is useful to case of mine.
This code below is a part of my project and it's worked perfectly
Code:
private Bitmap getBitmap(String url, String image){
String root = Environment.getExternalStorageDirectory().toString();
root = "/mnt/extSdCard/";
Bitmap bitmap = null;
File f=fileCache.getFile(url);
//from SD cache
bitmap = decodeFile(f);
if(bitmap!=null)
return bitmap;
try{
bitmap = BitmapFactory.decodeFile(root + image);
if(bitmap!=null){
return bitmap;
}
}catch (Exception e) {
e.printStackTrace();
}
//from web
if (netInfo != null && netInfo.isConnectedOrConnecting()) {
Foto foto = new Foto();
try {
try{
foto = new ObjectMapper().readValue(new URL("........."),
Foto.class);
if(foto!=null){

If I use `Environment.getExternalStorageDirectory().getAbsolutePath();` I can't get path of sd-card.
Thanks

Good luck
This is a program that I wrote to decode the newer style "logo.bin" files used in some OPPO, and OnePlus devices. Recently I have updated it to work with the OnePlus 3. It is backwards compatible with the old encoding. Please read below so you can better understand this type of encoding being used:
What Is A Raw Image?
A raw image, whether it be a file or an image in memory, is simply pixel data. There is no extra information like width, height, name, end of line... Absolutely nothing, just pixel data. If you have an image that is raw and the resolution is 1080x1920 and you are using a typical RGB24 or BGR24 (like the ones used here), then your exact filesize or size in memory will be 1080x1920x3! We use 3 here because there is one byte for the R or red component, one for the G (green), and one for the B(blue).
What Is A Run Length Encoded Image?
A run length image encoding uses a count ;usually a single byte (char), 2 bytes (short int), or 4 bytes (long int); and then the pixel components. So instead of writing out 300 bytes of '0's to make a line of 100 black pixels. Black is RGB(0,0,0). You could encode this as 100, 0, 0, 0. And only use 4 bytes of data to get the exact same image as the 300 byte raw image. All the run length encoding I've found, except the Motorola style which is a little different, use a run length encoding that is pixel-oriented like this.
Now I've figured out this new one and it is a byte-oriented run length encoding. This is for runs of bytes, not pixels. You may think, well whats the big deal? When you add a little area of color, you increase the run length encoded image in you logo.bin immensely! You use 6 bytes per pixel if there aren't any runs of color data. If you had an image that was a 1080x1920 black image with a 25 pixel horizontal line in the middle. The encoder would be doing runs of black data efficiently until it reached the red area.
.....0 255 0 255 0 255 0 255 0 255 0 133 /// we've reached the top left corner of the red line /// 13 1 30 1 255 1 // << that was just one red pixel!! in bgr color order (13, 30, 255) <<// And it keeps going through the rest of the red pixels on that line using 6 bytes per pixel, which is the opposite of compression. Before reaching the red line the encoding was decoding to 255 zeros over and over, until finally 133 zeros. 255 zeros is 85 black pixels stored in just 2 bytes!
This type of encoding is ONLY good for grey scale images. It is not good with color, but it still will handle color of course. In grey scale, the Red, Blue, and Green data components are always the same values. All the way from black (0,0,0) to white (255, 255, 255); including every shade of grey in between>>>(1,1,1) (2,2,2) (3,3,3)....(243, 243, 243) (254, 254, 254)<<<
One other difference in this method of run length encoding is that the color byte is before the count, which is backwards from all of the other methods.
The attachment contains the C source code (which is also in the 2nd post) and the executable that was compiled using mingw32 on a 64 bit Windows 10 PC. The PNG library that I used is LodePng, the source is in the download.
Big thanks to @scoobyjenkins for testing the old program on the op3 and sharing his results!! Also for testing this new version too!!
To use logoinjector:
Decode your logo.bin:
Code:
op3inject -i logo.bin -d
All the PNG 's will be extracted from logo.bin. Edit the PNG(s) that you want to change...
Note:
Your original "logo.bin" file is never changed, it is just read. If the file you try to load isn't a logo.bin file, or a different style, then the program will tell you and exit. This version is backwards compatible with the last OnePlus/OPPO encoding method. The only one it won't do, is the original one, that was not encoded, it was just pixel data.
Inject the image(s) back in to the logo.bin:
Code:
op3inject -i logo.bin -j fhd_oppo fhd_at
To list whats in your logo file:
Code:
op3inject -i logo.bin -l
For a more detailed list:
Code:
op3inject -i logo.bin -L
If the colors are messed up use the "-s" switch while decoding.
Code:
op3inject -i logo.bin -d -s
If you had to use the "-s" switch to decode properly, you'll have to use it to inject also:
Code:
op3inject -i logo.bin -j image_name -s
Note:
You can put as many names after "-j" as you want, and it's not case sensitive. You also don't have to put the whole name. If you just put "-j fhd" every image in the logo.bin that starts with "fhd" will be injected. There has to be a PNG with the name in the directory though
The size of your modified.logo.bin will displayed along with the original size, if everything went good. The 'splash' partition is 16 MB on the OnePlus 3. If you use too much color on too many of the 7 images you will easily go over 16 MB. The program will tell you and delete the "modified.logo.bin" that was created. If for some strange reason you would like to keep it, use the "-B" flag on the command.
Flash the "modified.logo.bin" file through fastboot.
Use this at your own risk.
Always make backups.
Always.

* - Fixed out of scope crash involving image #26 in oppo find 7 logo.bin (26 IS BIG)
* - Multiple injection names possible after the -j parameter
* - Injection names are now case insensitive
* - BGR is the the default color order, instead of RGB
* - Added more error checks
* - Show the change in file size of original logo.bin compare to the modified logo.bin
* - Several small changes dealing with readability
*
* New in v1.4:
*
* - Added the OnePlus 3's 4096 blocksize
* - General cleanup

How can I backup my original logo.bin file?

The logo.bin you supply isn't ever changed by the program, it is just modified on your computer, then reinstalled on the phone. Unless you are talking about acquiring the logo.bin in the first place? In that case check out this guide. The partition that you'll be trying to get is the "splash" partition, and that is your "logo.bin":good:

access adb and input code
Code:
adb shell dd if=/dev/block/sde17 of=/sdcard/partition/LOGO.bin
adb pull /sdcard/LOGO.bin

Does this mean we could potentially port this over to the OP3 and retain the smooth/flickerless transition from the splash screen to the bootanimation? http://forum.xda-developers.com/moto-e-2015/development/mod-nexus-6p-logo-bin-bootanimation-t3262923

If you wanted to use this logo injector to put a Google splash in your OP3 logo.bin so it matches a Google boot animation then I don't see why not! No porting needed as such, just extract the logo from the Nexus logo.bin, make it 1080x1920 and have at it!
Tapatalked that shiznit.
I cant flash my logo.bin.... "fastboot flash logo logo.bin" doesnt work error:
failed (remote: partition label doesn`t exist )
Bootloader is unlocked and device is decrypted.

Splash screen for FreedomOS users.
With white "FreedomOS" text: https://drive.google.com/file/d/0B-0rLZ5HEnOQdW9KOUw4LWJ2cGM/view?usp=sharing
Thanks @makers_mark for this tool !
I have compiled a linux version, see here
https://gitlab.com/Nevax/FreedomOS/blob/master/build/tools/op3injector
Flashed FreedomOS which came with a splash screen with no warning while flashing, could someone provide me the stock logo.bin file? Thanks in advance.
Thanks a lot for your work!! Will flashing this remove this Bootloader unlock warning??

Me too, want to go away from the freedom OS splash screen
Edit:
Found a flashable zip at freedom OS FAQs
@makers_mark is there any way to make -j compatible with directories? I have built this binary for android to work with my app and I already managed to add support for custom output directories but -j does not support directory names at all!
While this: "LogoInjector -i files/LOGO.bin -j 1-logo.png 4-fastboot.png" works fine, this: "LogoInjector -i files/LOGO.bin -j files/1-logo.png files/4-fastboot.png" does not... it throws an error saying: "files/1-logo.png is not in the logo bin" because it's actually looking for the string "files/1-logo.png" in the logo.bin and not "1-logo.png".
I tried fixing it but was unable to do so
