IndexedColorTable

Gets or sets the color table.

Declaration
public byte[] IndexedColorTable { get; set; }
Property Value
Type Description
System.Byte[]

The table of color components.
Remarks

The color table data must be m * (maxIndex + 1) bytes long, where m is the number of color components in the base color space. Each byte is an unsigned integer in the range 0 to 255 that is scaled to the range of the corresponding color component in the base color space; that is, 0 corresponds to the minimum value in the range for that component, and 255 corresponds to the maximum.

// Creates a new document
PdfDocument doc = new PdfDocument();
//Creates a new page and adds it as the last page of the document
