I don't quite understand what this is for. Can you give me a simple use case, please?

So that I could view the colors correctly in C#, I don't know why but I had to do that

var i = 0;
for (i = 0; i < stitchCount; i++)
{
IntPtr stitchPtr = IntPtr.Add(stitchesPtr, i * Marshal.SizeOf());
stitches[i] = Marshal.PtrToStructure(stitchPtr);
var flags = (StitchType)stitches[i].flags;
if (flags == StitchType.fSTOP || flags == StitchType.colorchnge)
{
var colors = Color.FromArgb(255,stitches[i-1].red, stitches[i-1].green, stitches[i-1].blue);
patternclass. AddColor(ref colors);
}
}

I already have a separate viewer in C# so I would only need the point listing and the color listing.

there is a reading error because the format does not read correctly, I haven't stopped yet to check the code
