Colors

Solid Colors

Solid colors can either be entered:

  • By name, for example: steelBlue
  • By RGB color components, for example: 70 130 180
  • By a hexadecimal RGB color code, for example: #4682b4

Named Colors

xmCHART has easy-to-remember names for the most common colors. Refer to table Color Names for the names. For example:

FillStyle(1;​red)

AddRect(10;​10;​200;​100;​steelBlue)

Named colors cannot be combined with an alpha value. Instead, use the equivalent RGB color components. For example:

FillStyle(1;​steelBlue 128) /* Error */

FillStyle(1;​steelBlue,128) /* Error */

FillStyle(1;​70 130 180 128) /* R G B A */

FillStyle(1;​#4682b480) /* #rrggbbaa */

RGB Colors

RGB colors are defined by three integers between 0 and 255, which represent the red, green and blue components. These three color components are separated by any whitespace characters, including space, tab, and new line. For example:

FillStyle(1;​255 0 0) /* Red */

FillStyle(1;​255 255 0) /* Yellow */

Transparency (alpha channel) is supported as optional 4th component between 0 (invisible) and 255 (opaque), default is 255. For example:

FillStyle(1;​70 130 180 255) /* Same as FillStyle(1;70 130 180) */

FillStyle(1;​70 130 180 200) /* Translucent */

FillStyle(1;​70 130 180 0) /* Transparent (invisible) */

RGB Hexcodes

Solid colors also can be entered as hexadecimal RGB color code (#rrggbb), along with an optional alpha channel (#rrggbbaa). r, g, b and a can be any hexadecimal digit (0–9, a–f). For example:

FillStyle(1;​#4682b4)

FillStyle(1;​#4682b480)

The short-hand forms #rgb and #rgba are converted into the six and eight digit forms by replicating digits. For example:

FillStyle(1;​#f0a) /* Same as FillStyle(1;#ff00aa) */

FillStyle(1;​#f0ab) /* Same as FillStyle(1;#ff00aabb) */

Color Gradients

Color gradients are available for all xmCHART fills, borders, texts, etc. and are defined by a list of numbers.

Linear Gradients

1 angle isScalableFlag offset1 r1 g1 b1 a1 offset2 r2 g2 b2 a2 ...

For linear gradients the first value of the list is always 1. The second value defines the direction of the gradient within a range of -360 and +360 degrees. 0 degree defines a horizontal gradient from left to right, 90 degrees a gradient from top to bottom. The third value is either 0 or 1, 1 means the angle of the gradient is linked to the width/height ratio of the bounding box, which is in most cases preferable. For example, for a diagonal gradient set the first three values to 1 45 1. On the other hand, if you set the third value 0 (e.g.: 1 45 0 ...) the direction of the gradient is always exactly 45 degrees regardless of the shape of the bounding box. These three values follows a series of color stops. A color stop is represented by five elements: offset, red, green, blue and alpha. Offsets are between 0 and 1, the four RGBA components are between 0 and 255. Color names and RGB hexcodes are not supported in combination with color gradients.

Radial Gradients

2 cx cy offset1 r1 g1 b1 a1 offset2 r2 g2 b2 a2 ...

For radial gradients the first value of the list is always 2. The second and third value represent the center point in relative coordinates in respect to the bounding box. For example, the center of the bounding box is defined by cx=0.5 and cy=0.5. These three values follows a series of color stops. A color stop is represented by five elements: offset, red, green, blue and alpha. Offsets are between 0 and 1, the four RGBA components are between 0 and 255. Color names and RGB hexcodes are not supported in combination with color gradients.
