[Insight-users] about BMP write and read

[Julien Jomier]

Hi Yixun,

What type of exception are you getting? Can you try to display the message?

The BMPImageIO should be able to read your image. (What version of ITK
are you using?).

If you can send me (or post on the web) one BMP file you are trying to
open I will see if I can read it.

Let us know,

Julien
