FromColor

Anonymous — Thu, 08 Sep 2005 21:45:46 GMT

I'm executing the following statement (or trying to at least):

Autodesk.AutoCAD.Colors.Color acadColor =
Autodesk.AutoCAD.Colors.Color.FromColor( System.Drawing.Color.Yellow );

This throws an exception with the message "eInvalidInput"

Any ideas why this command is throwing an expection?

I use the FromRgb:

Dim color As Autodesk.AutoCAD.Colors.Color
color = Autodesk.AutoCAD.Colors.Color.FromRgb(255, 255, 255)

Thanks Mikko

Yes, the FromRgb method works fine.

But, what is wrong with the Autodesk.AutoCAD.Colors.Color.FromColor( System.Drawing.Color) method.

My code is passes a System.Drawing.Color enumeration and I don't want to have to convert it to RGB.

it makes for really ugly code

Autodesk.AutoCAC.Colors.Color.FromRgb( System.Drawing.Color.Yellow.R, System.Drawing.Color.Yellow.G, System.Drawing.Color.Yellow.B )

I'd use numeric numbers.

Autodesk.AutoCAD.Colors.Color.FromRgb(255, 255, 0)

Pehaps I havn't made myself clear.

I'm trying to find out why the FromColor method throws an exception when passed a System.Drawing.Color enumerated value.

My code recieves as a parameter a System.Drawing.Color (not three RGB values). While I can use the System.Drawing.Color.R and .B and .G properties and the FromRgb method, it is much clearer code to use the variable that is passed.

So, once again I'll ask, what am I doing wrong that is causing the FromColor method to throw an exception?

Hmm, I get that same error using FromColor. FromColorIndex works. I have no idea how to use FromColor. Might look at that at another time.

Autodesk.AutoCAD.Colors.Color.FromColorIndex(ColorMethod.ByAci, 2)

Indeed this is a bug. I'll make sure that it gets fixed.
