• bgColor {string}, specifies the text's background color (CSScolor) (equivalent of <bgcolor> tag)
• shaColor {object}, specifies an object of {color, width, offset} type that defines the text's shadow (equivalent of <sha color;width;offset> tag), where:
  • color {string}, defines the color of the text's shadow (CSScolor)
  • width {number}, defines the size of the text's shadow

CSSColor or CSS legal color values can be specified by the following methods:

• Hexadecimal colors, is specified with: #RRGGBB, where the RR (red), GG (green) and BB (blue) hexadecimal integers specify the components of the color. All values must be between 00 and FF. For example, #0000ff value is rendered as blue, because the blue component is set to its highest value (ff) and the others are set to 00.
• Hexadecimal colors with transparency, is specified with: #RRGGBBAA, where AA (alpha) value must be between 00 and FF. For example, #0000ff80 defines a semi-transparent blue.
• RGB colors, is specified with the RGB(red, green, blue) function. Each parameter (red, green, and blue) defines the intensity of the color and can be an integer between 0 and 255. For example, rgb(0,0,255) defines the blue color.
• RGBA colors, are an extension of RGB color values with an alpha channel as RGBA(red, green, blue, alpha) function, where the alpha parameter is a number between 0.0 (fully transparent) and 1.0 (fully opaque). For example, rgba(0,0,255,0.5) defines a semi-transparent blue.
• HSL colors, is specified with the HSL(hue, saturation, lightness) function, where hue is a degree on the color wheel (from 0 to 360) - 0 (or 360) is red, 120 is green, 240 is blue. saturation is a percentage value; 0% means a shade of gray and 100% is the full color. lightness is also a percentage; 0% is black, 100% is white. HSL stands for hue, saturation, and lightness - and represents a cylindrical-coordinate representation of colors. For example, hsl(240, 100%, 50%) defines the blue color.
• HSLA colors, are an extension of HSL color values with an alpha channel - which specifies the opacity of the object as HSLA(hue, saturation, lightness, alpha) function, where alpha parameter is a number between 0.0 (fully transparent) and 1.0 (fully opaque). For example, hsla(240, 100%, 50%,0.5) defines a semi-transparent blue.
• Predefined/Cross-browser color names, 140 color names are predefined in the HTML and CSS color specification. For example, blue defines the blue color.

.

null {null}, the tfi field is ignored
  "bold monospace 16 <fg blue>" {string}, defines Monospace font of 16px height, bold and blue
  {bold: true, fontName: "monospace", fontSize: 16, fgColor: "blue"} {object}, defines Monospace font of 16px height, bold and blue

The wheelChange field specifies the amount the control scrolls when the user rolls the mouse wheel.

0 {number}, locks any action the mouse's wheel performs
  18 {number}, scrolls the control by 18-pixels when mouse's wheel is rotated (CTRL + wheel scrolls horizontally)

The zoom field defines the zoom factor of the control's content. The zoomLevels field defines the margins of the zoom-factor the control is allowed to magnify. The zoom field can be any value between 10 (10%) and 1000 (1000%).

null {null}, Specifies normal-view (100%)
  150 {number}, Indicates that the control's content is magnfied to 150%

The zoomLevels field defines the zoom-levels the user can magnify the control's content (specifies a list of numbers separated by comma that indicates the zoom-levels/zoom-margins the control's content is allowed to zoom).

null {null}, Specifies that the control's zoom factor is always 100%
  150 {number}, Specifies that the control's zoom factor is always 150%
  "50,100,200,350" {string}, Indicates that the zoom-factor can be any of selected values, and the margins of zoom-factor is 50% to 350%
