Logo Swapper [Windows application]

Logo Swapper

Microsoft .NET Framework Version 2.0 is required.

* Purpose :
-------------
Possibility to replace bitmaps contained in Rockbox binary files.
Is mainly intended to "easily" change logos.

* Supported models :
----------------------
- From my testings, it is alright with all simulators.
- And it should be OK with all "real" players models, except the Archos series.

--------------------------------------------------------------------

ill give it a try and post back

thanks

i dont think this works for the H10 20G?

[spiral]

i would really like to test your programm
but it seems that it is not possible to use is it with your multibuild
but wait while i'm writing this i think i should download the sourcecode to get the target images...right?

ok nevermind i will try it

[Philip_0729]

anyone know where to download bitmaps of the original images from the norb/ashen multi-build??? they are needed to use this program...

Right!
Here are some logos :

Current official ROCKbox logos :

h300

h100

h10 - 20gb

h10 - 5gb

Other logos :

norbu build - Eye
Author:Nico DE.


norbu build - Green

PS: To upload these logos here, i had to convert them into the PNG format.
It is needed to convert them back to the BMP format.

[Danfried]

Too bad I didn't notice this thread earlier -- I've wanted to be able to switch logos since first using Rockbox; it's one of the few things you can't easily customize without compiling your own build.

Thanks to Ashen, will try this out.

[Philip_0729]

Thanks Ashen, now to get skinning

[Big_Mac]

This will be neat, now I won't have to compile everytime I make a new boot image

[SuperTom85]

so does this work for the 20gb?

Maybe. If you could tell me...

[SuperTom85]

well, i tried it out a while ago, and it didnt seem to work. But i wasn't sure if i was doing it right! that's why i asked!

[Mike]

Well, I must be dense today, because it doesn't seem to be working for me.

I have Microsoft .NET installed via the above link, but when I try to run the program, I get an error meassage. "The application failed to start because cygwin1.dll was not found."

??

Also, I don't quite follow what to do at one point:

Step 3 says,

Step 3: By clicking in the small left frame, browse to the path that leads to the bitmap file of the logo you wish to replace. Indeed, it is required to point out which image it is, because LogoSwapper will try to locate the corresponding converted bytes in the Rockbox binary file.

So does this mean that one simply needs to have a copy of the relevant original logo bmp file around so that LogoSwapper can use that original file's identifying information; and not that one needs to apply LogoSwapper as against source (uncompiled) code? (Or does one need to have downloaded the full Rockbox source code; make the logo swap by identifying the original logo bmp file; and then compile?)

I assume i'm missing something here (I heaven't had my morning coffee yet)--help?

Last but not least: is one restricted in the replacement logo size by the physical size of the original logo bmp file? Eariler, I had done up a replacement logo bmp file that is larger in dimensions than the original but that still fits the player's screen, and was able to substitute that bmp for the original and then to compile the code, without any problem; may I use that larger-sized logo bmp with LogoSwapper?

Thanks--

Looks like a really cool app. Unfortunately, it won't work for me. I load my settings (Ipod Video) and images but then a message saying 'application has failed to start because cygwin1.dll was not found' pops up. Any help would be greately appreciated,
Thanks,
Jack

Looks like an awesome app. I will be using it to mod out my players as soon as i get the .net framework installed (You forced me to!) so yeah. Will post if it works.

That cygwin problem might be solved by getting cygwin yourselves. I might have to investigate.

EDIT: I think you need to make an option to save the current image. That might be useful. I'd be happy to help if you gave me the source code.

EDIT2: I see why you can't jsut extract it. Right. Ill need to find the right image for my build then...

EDIT3: Bitmaps for all targets are available here:
http://svn.rockbox.org/viewvc.cgi/tr...?pathrev=12987

EDIT4: Ok i get the cygwin1.dll error. I will try to find a fix.

EDIT5: Downloading a copy of the cygwin1.dll fixes that error, but now i get the following error instead:

I will be retrying with my other player...

EDIT?:Attempting to modify the current CVS version of rockbox.ipod (for 5g) gives the follwing error:

I have a fairly dated copy of norbu's build, and I saved the boot image that was posted in this thread and tried it out but it said that it was unable to locate the left image. Any ideas?

[Subterranean]

Very nice program, I enjoy making small useful programs like this, so I know it can be more difficult/time consuming than one would think.

One small annoyance; on clicking info, the help box is loaded modal, so that you cannot go back to the main program and follow each step one at a time. It might be better having it load as a seperate normal form instead.

Another suggestion; on selecting a rockbox binary file, could the program search through it for images (I would think the bitmap headers at least would be distinct from other code) and then give the user the ability to look through them. This would stop the (very small) chance that a random piece of code could be overwritten as you mention, and would be slightly more intuitive to the user. Having not studied the rockbox binary format I'm not 100% certain this would be possible.

Also if you want a hand or anything I would be happy to help, I guess you have written this in C#?

[Mike]

Subterranean, were you actually able to get the program to work?

As you see above, others of us haven't been able to ...

Ashen, where are you ?!?

[jj oo ee yy]

wow this program looks good

i was just wandering were i obtain the binary files for the players so i can use this program, i cant find it. is it just me or am i completely blind. I use an Iriver h10 5G. or is the h10 not supported anymore?
also the people over at iaudiophile i think have been able to have success. Here is the link http://www.iaudiophile.net/forums/sh...ad.php?t=13932 i don't know if thats any help or not, sorry if its not just trying to help.

great program thanks
JJ

[iwantanimac]

Erm... the binary file is already on your player. the rockbox.model file.

As for the logos for each model, see
http://svn.rockbox.org/viewvc.cgi/tr...?pathrev=12987

[jackrayers]

Yay, got it to work, just google cygwin1.dll, download it, place in the file that the app exists in and walla!

[jj oo ee yy]

oh thank you for that iwantanimac. i thought that might be the binary file but i was not 100% sure. ill test it now and see what happens
