GrapeCity.Documents.Imaging.Indexed4bppBitmap
Indexed4bppBitmap Class
Represents a palette-color image with 4 bits per pixel.
Namespace: GrapeCity.Documents.Imaging
Assembly: DS.Documents.Imaging.dll
Syntax
public class Indexed4bppBitmap : IImage, IDisposablePublic Class Indexed4bppBitmap
Implements IImage, IDisposableConstructors
| Name | Description |
|---|---|
| Indexed4bppBitmap(int, int, bool, bool, bool, float, float) | Initializes a new instance of the Indexed4bppBitmap class. |
Properties
| Name | Description |
|---|---|
| ColorMap | Gets the associated lookup table with 16 Red-Green-Blue[-Alpha] palette entries. |
| DpiX | Gets the horizontal dpi of the bitmap. |
| DpiY | Gets the vertical dpi of the bitmap. |
| ExifProfile | Gets or sets an instance of ExifProfile with Exif metadata of the image. |
| IccProfileData | Gets or sets the raw ICC profile data. |
| IsDisposed | Gets a value indicating whether the Indexed4bppBitmap has been disposed of. |
| this[int, int] | Gets or sets a lookup table index (from 0 to 15) at the specified coordinates. |
| LowerBitsFirst | Gets or sets a value specifying whether pixels with lower column indices are stored in the lower-order bit tetrads of the byte. Setting this property causes an update to the pixel data. |
| Opaque | Gets or sets a value indicating whether the alpha channel of the image should be ignored. |
| PixelHeight | Gets the pixel height of the image. |
| PixelWidth | Gets the pixel width of the image. |
| Premultiplied | Gets or sets a value indicating if the color channels for all pixels are premultiplied by the alpha channel. |
| RawData | Gets a pointer to the internal binary data. |
| Rotation | Gets the flip and rotate transformations that must be applied to the image. |
| ScanLineLength | Gets the number of bytes in one scan line. |
Methods
| Name | Description |
|---|---|
| ApplyLicenseKey(string) | Applies a license key to an instance of Indexed4bppBitmap. |
| Clear(int) | Clears the Indexed4bppBitmap with the specified lookup table index (from 0 to 15). |
| Clear(int, Rectangle) | Clears the Indexed4bppBitmap with the specified lookup table index (from 0 to 15). |
| Clip(Rectangle) | Creates a new Indexed4bppBitmap with a fragment of the image. |
| Clone(bool) | Creates a new Indexed4bppBitmap with a copy of the image. |
| CompactPalette(bool) | Compacts the image palette to 8 bits per color channel and returns the palette as an array of 32-bit ARGB values. |
| Dispose() | Clean up any resources being used. |
| Dispose(bool) | Performs cleanup operations on managed and unmanaged resources. |
| SetDpi(float) | Changes the physical resolution of the image. |
| SetDpi(float, float) | Changes the physical resolution of the image. |
| ToGcBitmap() | Creates an instance of the GcBitmap class from the current Indexed4bppBitmap. |
| ToGcBitmap(GcBitmap, bool) | Copies the image into an existing instance of GcBitmap. |
