CBM image file format: what is it? how to read?

Question

I have a collection of images in CBM format. What is this format? How to read it? How to convert it to, say, a BMP raster image?

Searching the net, I discovered that this could mean one of three things:

1) Fuzzy raster image , according to the library of Michael Moldin, FBM (1989). XnView and Graphics Convert Pro 2011 software should be able to open it, but it is not. Most likely, this means that the file I have is not really a Fuzzy Bitmap.

2) Compiled raster image , in accordance with XLib ( wikipedia ) How to proceed to verify that my file is such a compiled raster file? Where to download XLib / what should I build?

3) Compressed bitmap . Do you have more information about this format?

Answer 1

I found CreateDIBitmap . If you pass the correct parameters, you can save it to a more well-known file format.

Here you can find something about Bitmap Compression .

If you do not know the details of the image, such as resolution, bit per pixel, compression type ... It will be difficult to read.

Answer 2

I believe CBMs are simply renamed Zip files. Try renaming and unzipping.

Answer 3

try opening it with konvertor (www.konvertor.net); he reads several CBM formats.
