Color - Color(Array colors)
Instantiates a new Color object with RGB values.
Color can be applied to the following scenarios:
| Name | Type | Description |
|---|---|---|
| colors | Array | Three numbers indicating RGB values using
a decimal value from 0 through 1. For example, in [0.1, 0.9, 0.5],
the value of the first position is red, second is green, and third is blue. Also,
[0, 0, 0] is solid black, [0.5, 0.5, 0.5] is
solid gray, and [1, 1, 1] is solid white. |
The following example shows how to create a Color object.
var color = new sn_pdfgeneratorutils.Color([0.1, 0.9, 0.5]); //given as object containing RGB values
Color – equals(Color color)
Indicates whether the values of two different color objects match.
| Name | Type | Description |
|---|---|---|
| color | Color | Color object to check for a match. |
| Type | Description |
|---|---|
| Boolean | Flag that indicates whether the values of two color objects match. Valid values:
|
The following example shows how to create two color objects and determine if the colors match.
var color1 = new sn_pdfgeneratorutils.Color([1,0.5,0.5]); // given as an array of RGB values
var color2 = new sn_pdfgeneratorutils.Color([0.8,0.5,0.5]); // given as an array of RGB values
var isequal = color1.equals(color2);
Color – getGrayColor(Number grayScale)
Returns a black, gray, or white color object.
| Name | Type | Description |
|---|---|---|
| grayScale | Number | Decimal value in the range 0 through 1, in which 0 is black and 1 is white. |
| Type | Description |
|---|---|
| Object | Color object reflecting the provided grayscale value. |
The following example shows how to create a color object that is 50% grayscale.
var grayColor = new sn_pdfgeneratorutils.Color.getGrayColor(0.5);
Color – setColorValue(Array colors)
Creates color with given values and enables you to change the values of an existing color. Each of the values must be from 0 through 1.
| Name | Type | Description |
|---|---|---|
| colors | Array | Three numbers indicating RGB values using
a decimal value from 0 through 1. For example, in [0.1, 0.9, 0.5],
the value of the first position is red, second is green, and third is blue. Also,
[0, 0, 0] is solid black, [0.5, 0.5, 0.5] is
solid gray, and [1, 1, 1] is solid white. |
| Type | Description |
|---|---|
| None |
The following example shows how to change the values of an existing color.
var color = new sn_pdfgeneratorutils.Color([1,0.5,0.5]); //given as array of RGB values;
color.setColorValue(color);
Color – setOpacity(Number opacity)
Sets the level of color opacity.
| Name | Type | Description |
|---|---|---|
| color | Color | Floating decimal value from 0 through 1, in which 0 is fully transparent and 1 is fully opaque. |
| Type | Description |
|---|---|
| None |
The following example shows how to create a color object and set its opacity to 50 percent.
var color = new Color([1,0.5,0.5]);
color.setOpacity(0.5);
