Method ConvertGRAY8
ConvertGRAY8()
Creates a new ImageBuffer with pixel data converted to 8-bit grayscale (GRAY8).
public ImageBuffer ConvertGRAY8()Returns
- ImageBuffer
A new ImageBuffer instance with grayscale pixel data.
Remarks
When converting from RGB24 or RGBA32, the grayscale value of each pixel is computed using a weighted luma formula that approximates human brightness perception (commonly based on ITU-R BT.601 coefficients).
If the image is already in grayscale, this method produces a deep copy of the image data.
Exceptions
- InvalidOperationException
Thrown if the native conversion fails.
- ObjectDisposedException
Thrown if this instance has been disposed.
