Dan and others trying to use libbsb in windows,

I hope I am not misunderstanding but...you don't need to compile libbsb to be able to use it in WindowsXP.

I am writing this quite thoroughly as I think some readers of the forum are not comfortable using a command window. Please bare with.

Just download the file libbsb-0.0.7-win32.zip from here:
Browse libbsb - read/write/convert BSB images Files on SourceForge.net

Then unzip it to a folder of your liking, e.g straight under c:\
c:/libbsb-0.0.7
You will have to add the path statement by clicking
start->settings->control panel->system
then choose the "advanced" tab, click on "environment variables"
Scroll down in the lower box to "path" and click "edit", add ";c\libbsb-0.0.7" at the end of the existing line. Observe the leading semicolon! And be careful, making a mistake here will create problems for those not used to fiddle with this!
(The path variable means that windows will find the program when we need it later)

Now you are done. Let us try:

1. Create a new directory, e.g. c:\kap
2. Copy the file "c:\libbsb-0.0.7\tests\australia4c.tif" to "c:\kap"
3. Create a header file. We can do this by opening c:\libbsb-0.0.7\australia4c.kap with wordpad. Erase all lines with garbled text! (all lines after the line starting with: RGB/4,226,65,6)
4. Save the file as c:\kap\header.kap
5. We now have two files in "c:\kap", one header file (.kap) and one image file (.tif). Let us make ourselves a "new" kap to use in Opencpn.
6. Open a command window; click:
start->run and write cmd in the box and click "ok". A command window will open. Write the following to commands:
c:\>c: (and press enter)
c:\>cd c:\kap (and press enter)
These two commands will make us move to the "c:\kap" directory
Check were you are and what files are there by writing:
c:\kap\dir
You should see two files "header.kap" and "australia4c.tif"
7. Let us try converting, write:
C:\kap>tif2bsb (and press enter, you will see the following instructive text)
Usage:
tif2bsb [-c colormap-size] template.kap input.tif output.kap
Try it out, write:
c:\kap>tif2bsb -c 4 header.kap australia4c.tif calibrated.kap
Now you should have a new calibrated file. Check by writing:
c:\kap\dir
You should have three files now!

The tif2bsb is the command used to actually create the new kap file.
-c 4 indicates that it is a 4 color tif.
The actual tif2bsb.exe file is found by the path we set earlier, it is located in c:\libbsb-0.0.7.

Some hints:
-It is a good idea to read the c:\libbsb-0.0.7\readme file. (open it in WordPad, not in Notepad)
-Read all the info about the libbsb package on sourceforge.
-Make another new directory were you place the calibrated kap files. otherwise opencpn will try to use the header files and they contain only headers, no image!

My conclusions:
The programs in libbsb-0.0.7 seem to work ok in Windows XP, the problem is that they don't give any error messages with useful information. Any mistake in the command line, the tif file or the kap file will make the tif2bsb crash.
This makes it hard to find out why the header.kap files you make yourself don't work. It would be great with a front end program to tif2bsb similar to the Seaclear "MapCal II" program for it to be of practical use for us windows people.

Anyway, I hope this make it possible for more people to try it out and try to figure out more about how to make the kap files. I had no luck with the nz53.tif file which was discussed earlier. It converted just fine but was not possible to use in Opencpn or Seaclear for me. (but the australia4c.kap works fine in both)

I reported it to the list. They say that has been fixed in the latest release. So I got it, figured out gunzip and tar, and it went through the ./configure, make, make check and make install. I got the logs if you want to see them.

So, theoretically I have libtiff installed. But I still can't get libbsb to see that it's there.

I posted my last before I saw this. THANKS! I will try that route.

Jonas, thanks for helping out here.

I don't get much in the way of error messages with libbsb on linux either. If we restrict ourself to the NZ tiffs for now, I only ever see a message about a non recognized tag in the picture, but a kap file is still produced. If you make a mistake in the template.kap file, you get no messages. It is very important that all the "," and "." are correct, and that you use the correct signs for lat and long ( +N,-S,+E,-W), etc...

What exactly happens when you try NZ53 on OpenCpn???
Do you get log messages like this?

10:16:12: Create ChartTable Entry for /opt/Navigation/Raster2Bsb/NZ/INT638.KAP
10:16:33: Initializing Chart /opt/Navigation/Raster2Bsb/NZ/INT638.KAP

If you tick the box "Show Chart Outlines", can you then see the outlines of the chart in opencpn?

With the Windows version, yes it works with the australia map. But when I try a NOAA map, it doesn't.

bsb2tif worked. Gave me a tiff of the chart (11402_1).

C:\libbsbwork>bsb2tif .\from\11402_1.KAP .\to\11402_1.tif

Then I created the header file and tried the other way.

C:\libbsbwork>tif2bsb .\to\11402_1.tif .\to\11402_1.KAP .\to\11402_1_new.KAP
.\to\11402_1.KAP: Not a TIFF file, bad magic number 3361 (0xd21).
Could not TIFFOpen ".\to\11402_1.KAP"

From the libbsb docs, I find this:
Not a TIFF file, bad magic number %d (0x%x). The magic number in the header was not (hex) 0x4d4d or (hex) 0x4949

So, maybe we need a hex editor?

But, I think the way to go is look at the australia map. I thought I might learn something from the headers in the NOAA file, but they got lots of stuff in there... 26k of headers.

Among other things:

• 10 RGB values
• 10 more RGB values for each of the different color schemes - DAY, DSK, NGT, NGR, GRY, PRC, PRG
• 135 REFerence points (with a corresponding 135 ERR points)
• and a bunch of other stuff

I think the RGB values may be a problem when working on other unknown charts. But that may be the least of it.

Usage:
tif2bsb [-c colormap-size] template.kap input.tif output.kap

You have the wrong order between the arguments.
Your error message is because a .kap is not a tiff.
Check my earlier posts.

Yep, I figured that out. I will try again later, but right now I am heading down a different road...

[dacust]

I have been paring down the header file to see what might be optional.

This is from the australia4c example.

Red means I deleted it.

It still displays fine. On their webpage, they didn't know what the P values were. And if the RGB isn't needed, that would help a lot.

There is a lot of text in the headers of different .kap files that I don't understand, and that don't seems to be necessary.
See post #5 for a basic template. You don't need RGB values in the template file as tiff2bsb is creating its own.

What I'm more concerned about is the REF/, lines, reference points for geo referencing. This has to do with the accuracy of the finished file. For a large scale chart, such as a harbor plan, the four corners will probably do, but for small scale charts that spans thousands of miles in north - south direction you need more points to help opencpn. I'm still pondering the finer points of this.

Do you have any success making NZ53 using the template file I attached i #5 ?

Would it help to use a tag viewer like this?

X360 Exif & Tiff Tag Viewer ActiveX Control helps application developers and programmers to get all embed image information including EXIF tags, TIFF tags and GPS tags. Also, you can use it as a simply image viewer ActiveX with many useful viewing functions. The ActiveX works on most of the Windows operating system. The functionality of the product can be accessed from most programming languages like C++, Visual Basic, Visual FoxPro, Delphi, MS Access, VB.NET and C#.

With X360 Exif & Tiff Tag Viewer ActiveX Control, you can:

Get all embed information from Jpeg, Png and Tiff image.

Embed image information include Exif tags, Tiff tags and Gps tags.

Get count, display value, hexadecimal value and type of all tags.

I downloaded libbsb-0.0.7 and configured system path as follows:
%SystemRoot%\system32;%SystemRoot%;%SystemRoot%\Sy stem32\Wbem;C:\Programfiler\Common Files\Ulead Systems\MPEG;C:\Windows\QTSystem\;c\libbsb-0.0.7D:\Programfiler;

(NOTE: My Vista is in Norwegian,hence the path:c:\Programfiler)

When I run C:\>kap>tif2bsb I get the message 'ingen tilgang' 'no access' ??

I created the two file directories c:\libbsb-0.0.7 and c:\kap

What could be the problem?

One thing I see is a missing simicolon. I added it above. And you say c:\Programfiler, but your path has D:\Programfiler.

Dan...

Exactly what I did but I am advised 'no access' ? I have tried using both 'PROGRAM FILES' as well as the Norwegian 'Programfiler' without any luck,and this is where I'm stuck!

Any chance you could try another conversion for me? nz5322.tif in my dropbox
