Using color in PDF document

UniPDF allows for setting color for text, line, and many other elements. 

The simplest way of using color in UniPDF is by using the predefined colors

blackColor   := creator.ColorBlack
whiteColor   := creator.ColorWhite
redColor     := creator.ColorRed
greenColor   := creator.ColorGreen
blueColor    := creator.ColorGreen
yellowColor  := creator.ColorYellow

You can also defined your own color by using RGB or CMYK color model.

RGB Color

There's multiple way to define an RGB color

1. ColorRGBFrom8bit
   
   This function accept three parameters: red, green, and blue value.
   Each is value must be between 0 - 255.
   
   

   red := creator.ColorRGBFrom8bit(255, 0, 0)
   	

2. ColorRGBFromArithmetic
   
   This function accept three parameters: red, green, and blue value.
   Each is value must be between 0.0 - 1.0.
   
   

   green := creator.ColorRGBFromArithmetic(0.0, 1.0, 0.0)
   	

3. ColorRGBFromHex
   
   This function accept one parameter, which is a hex color code.
   
   

     blue := creator.ColorRGBFromHex("#0000ff")
   	

CMYK color

To define a CMYK color, this following function could be used

1. ColorCMYKFrom8bit
   
   This function accepts four parameter: cyan, magenta, yellow, and black color value.
   Each value must be between 0 - 100.
   
   

   cyan := creator.ColorCMYKFrom8bit(100, 0, 0, 0)
   			

2. ColorCMYKFromArithmetic
   
   

   This function accepts four parameter: cyan, magenta, yellow, and black color value.
   Each value must be between 0.0 - 1.0.

   magenta:= creator.ColorCMYKFromArithmetic(0.0, 1.0, 0.0, 0.0)
