Class ColorPalette
Namespace: Aspose.Imaging
Assembly: Aspose.Imaging.dll (25.2.0)
Defines an array of colors that make up a color palette. The colors are 32-bit ARGB colors. Not inheritable.

Constructors
ColorPalette(int[], bool)
Initializes a new instance of the Aspose.Imaging.ColorPalette class.
[JsonConstructor]
public ColorPalette(int[] argb32Entries, bool isCompactPalette)Parameters
argb32Entries int[]
The 32-bit ARGB color palette entries.
isCompactPalette bool
Indicating whether compact it palette.
ColorPalette(int[])
Initializes a new instance of the Aspose.Imaging.ColorPalette class and IsCompactPalette is false.
public ColorPalette(int[] argb32Entries)Parameters
argb32Entries int[]
The 32-bit ARGB color palette entries.
ColorPalette(Color[], bool)
Initializes a new instance of the Aspose.Imaging.ColorPalette class.
public ColorPalette(Color[] entries, bool isCompactPalette)Parameters
entries Color[]
The color palette entries.
isCompactPalette bool
Indicating whether compact it palette.
ColorPalette(Color[])
Initializes a new instance of the Aspose.Imaging.ColorPalette class and IsCompactPalette is false.
public ColorPalette(Color[] entries)Parameters
entries Color[]
The color palette entries.
Properties
Argb32Entries
Gets an array of 32-bit ARGB structures.
public int[] Argb32Entries { get; }Property Value
int[]
Entries
Gets an array of Aspose.Imaging.Color structures.
public Color[] Entries { get; }Property Value
Color[]
EntriesCount
Gets the entries count.
public int EntriesCount { get; }Property Value
IsCompactPalette
Gets or sets a value indicating whether compact palette is used.
public bool IsCompactPalette { get; }Property Value
Remarks
Compact palette means that image will contain only the specified palette entries if possible or in other words the image will be more compact and occupy less space; otherwise there will be 2^BitsPerPixel entries and image will reserve more space for all possible palette entries. Setting this value to true and changing palette entries may cause performance penalty since data movement may occur so use it carefully.
