 | AdjustLevels | Adjusts the levels of an image histogram.
The method maps the input range of values (blackPoint..whitePoint) to the output range (outputBlack..outputWhite) using the specified gamma correction (midtone). |
| ApplyGaussianBlur | オーバーロードされます。 Applies a Gaussian blur to this GrayscaleBitmap. |
| ApplyGlow | When applied to a grayscale mask built from a color image using the ToGrayscaleBitmap method, modifies it so that the result can be used as a transparency mask to produce Glow or Soft Edges effect. |
| ApplyLicenseKey | Applies a license key to an instance of GrayscaleBitmap. |
| AutoContrast | オーバーロードされます。 Modifies pixel intensities such that available range of values (0..255) is fully covered. |
| Clear | オーバーロードされます。 Clears the GrayscaleBitmap with the specified value (from 0 to 255). |
| Clip | Creates a new GrayscaleBitmap with a fragment of the image. |
| Clone | Creates a new GrayscaleBitmap with a copy of the image. |
| Dispose | Clean up any resources being used. |
| InvertColors | Inverts the pixel colors from black to white and vice versa. |
| SetDpi | オーバーロードされます。 Changes the physical resolution of the image. |
| ShrinkPixelFormat | Changes pixel format from 8 bits per pixel to lower value with two-dimensional error diffusion. |
| ToGcBitmap | オーバーロードされます。 Creates an instance of the GcBitmap class from the current GrayscaleBitmap. |
| ToShadowBitmap | オーバーロードされます。 Creates a semi-transparent GcBitmap from the current GrayscaleBitmap.
This method treats the current GrayscaleBitmap as a transparency mask, regardless of the TransparencyMask property value. |
