Convert Binary image (.BIN) to other image format (e.g. PNG)

Fightspit · Post #1by **Fightspit** » 30.09.2006, 11:43

I already downloaded the "bmng" data (world.200406.3x86400x43200.bin.gz) and I finished to decompress it (it takes 10 GB :!:

).

After searching with google how to convert a binary picture to an other format without sucess

, I ask you if you know an utility or a "SINGLE" command line (as t00fri :wink:

) which can do it (I hope :roll:

).

Thanks for the help :!:

ImageMagick and NetPBM both are command line utility packages that can convert among different image formats. Neither one understands DDS/DXT, though. Both are freeware and available for multiple platforms.

I have already got Imagemagick but it doesn't support ".bin" format:

I am not sure that NetPBM recognize ".bin" images:

IM can open the .bin file. Rename it to .rgb and give dimensions and depth info on the command line.

Code: Select all

convert -size 86400x43200 -depth 8 world.200406.3x86400x43200.rgb blue-marble.png

Edit: It's been a while and the depth may be wrong or unnecessary.

Of course it works, but you havn't got enough cache space on your hd! You need ~ > 50 GB FREE space where you started convert. IM is highly inefficient and incredibly slow for VERY big files. It's just not suited...

I do the conversion directly with my custom code, which is VERY easy and fast.

It doesn't work with or without depth option

EDIT: I have a bug with this post

and I don't know why ...

Wow

50 GB

thanks for advise.

I just looked at my bash history and i think the - depth 8 was used. I couldn't find that exact command though. I used to get those eof errors and it was caused by not enough memory or pixel cache that a too small. IM would crash with a eof when it ran out of memory. The other reason I got them was the file was corrupted by the extraction process.
If you have the space you need to set an environment variable for IM's pixel cache. I beleive IM needed about 60 GB to process a rgb file that large.

If you have access to Photoshop try renaming the extension to .raw and input the image parameters in the 'Photoshop RAW Options' dialog:

Dimensions
Width: 86400
Height: 43200

Channels
Count: 3
Depth: 8 bits
Byte Order: Mac

Header
Size: 0

----------
Note: I don't recall if the byte order is Mac ("Big Endian") or IBM PC ("Little Endian") so try one or the other if the file loads improperly.
----------

BTW, unless you REALLY need this file in this form it might be easier just to use the 500 meter non-shaded BMNG PNG tiles. They're exactly the same.
