RE: [Vxl-users] Converting a vil1 image to vil

[Ian S. <ian...@st...>]

I don't know about the GUI code, but the vil/vil1 code looks ok (apart from
the fact that you don't appear to have any reason to convert it from a vil1
to vil image and then back again.)

Can you reproduce the problem in a smaller example? Does it depend on the
type of image file you use? To help you solve this problem, we really need
to know where error is raised. A whole stack trace would be useful for this.
More details such as a description of the error, the platform/GUI toolkit
you are using, compiler name and version, are also often useful when
tracking down bugs.

Ian.
