Hi,

I am using 14.5 C++ class lib.
When I save 16 bit grayscale image to bitmap format, I realize the annotations I did in it as well.
I found that the color of the realized anotation became grayscale. I want to keep the color of them when they were drawn.
Is it possible? I know mybe I have to change the lookup table.

Thanks.

Lei,

To keep the color of the Annotation objects, change the bits-per-pixel of the image to 24-bit before realizing the Annotations.
You can change the bits-per-pixel by using the LBitmapBase::ColorRes method.

To change the bits-per-pixel of an Image in C# or VB.NET you can use the ColorResolutionCommand Class.
