Hi -

We just upgraded to LEAD version 17 from version 16.5. We use VB.net. In version 17, creating a New RasterImage from a System.Drawing.Image no longer works as it did in version 16.5. The code given below works in version 16.5, but won't compile in version 17:

Dim plainImage As Image = My.Resources.testImage
Dim rImage As New RasterImage(plainImage)

Is there another way to accomplish the same thing in version 17?

I should add, the exact error reported by visual studio during the build process is:

Value of type 'System.Drawing.Image' cannot be converted to 'Leadtools.RasterImage'.

This can still be done we just changed how this occurs in V17.

This link shows how this would be done now.

Thank you - is there any document that summarizes the major areas where "...we just changed how this occurs in v17..." bits where things are different in version 17 from version 16.5? That would make it easier to track some of these issues down.
