-h <height> Image height in pixels. If not specified will be autodetected.
-t <pattern> Manually specify the padding pattern (usually 0 or 255).
-p <size> Manually specify the padding size.
-n Do not add HTC splash signature to NB file.
-s Output smartphone format.
NBH arguments: (only when converting from BMP to NBH)
-D <model_id> Generate NBH with specified Model ID (mandatory)
-S <chunksize> NBH SignMaxChunkSize (64 or 1024)
-T <type> NBH header type, this is typically 0x600 or 0x601

Hi Pau,
I found your nbbmp converter through XDA and came upon your blog here via Google. I was thinking about making a simple gui-based application to do a similar process, and was wondering two things.
1) How were you able to figure out the format details of the NB file type? Is there a specification somewhere or did you somehow reverse-engineer it.
2) If there isn’t a spec somewhere, would you be ok with my using your file as a reference in making my own application, if I do end up making it?
Thanks!

Hi,
1) no specs as far as I know, I reversed it using imagemagick but that was quite a long time ago and I can’t remember the specific details now.
2) feel free to use my source as a reference, no problem at all. The code is licensed under the GPL3.
On lines 430, 453, 461 of source v1.1 above, require the following changes:
430:
(-) sprintf(filename, optarg);
(+) sprintf(filename, “%s”, optarg);
453:
(-) sprintf(modelid, optarg);
(+) sprintf(modelid, “%s”, optarg);
461:
(-) sprintf(type, optarg);
(+) sprintf(type, “%s”, optarg);
Built in Ubuntu 10.10 x64.
Thank you so much =) Please add this fix to 1.2!
Sorry for being daft, but how do I run this in Linux?
You need to compile it first: gcc nbimg.c -o nbimg
When I convert 24bit image (Original http://yfrog.com/hskbrtp ), I got 24bit image that looks like 16bit image (Converted image http://yfrog.com/kjnlfp ).
Can you give me a favor, so I can deal with this problem?
Doesn’t work. Command not found even after compiling.
In linux I mean, tried both versions. Using ubuntu 10.10
Run it with ‘./nbimg’ instead of ‘nbimg’, because it is not in your $PATH.
