Defines an array of colors that make up a color palette. The colors are 32-bit ARGB colors. Not inheritable.
Assembly: System.Drawing (in System.Drawing.dll)
Thetype exposes the following members.
|Equals(Object)||Determines whether the specified object is equal to the current object. (Inherited from Object.)|
|GetHashCode||Serves as the default hash function. (Inherited from Object.)|
|GetType||Gets the Type of the current instance. (Inherited from Object.)|
|ToString||Returns a string that represents the current object. (Inherited from Object.)|
You are not allowed to construct a object directly. If you created a object, you could then manipulate the palette size for a particular image, which is not allowed. Use the Image.Palette property to obtain a object.
The colors in the palette are limited to 32-bit ARGB colors. A 32-bit ARGB color has 8 bits each for alpha, red, green, and blue values. The lowest 8 bits make up the blue bit, the next 8 bits are green, the next 8 bits are red, and the most significant 8 bits are alpha. This means each component can vary from 0 to 255. Fully on is 255 and fully off is 0. Alpha is used to make the color value transparent (alpha = 0) or opaque (alpha = 255). The number of intensity levels in the image can be increased without increasing the number of colors used. This process creates what is called a halftone, and it offers increased contrast at a cost of decreased resolution.
