class drawing_export_ color : public xtd::object

Inheritance

xtd::object → xtd::drawing::color

Namespace

xtd::drawing

Library

xtd.drawing

Remarks

Named colors are represented by using the properties of the xtd::drawing::color structure. For more information about these colors, see Colors by Name.

The color of each pixel is represented as a 32-bit number: 8 bits each for alpha, red, green, and blue (ARGB). Each of the four components is a number from 0 through 255, with 0 representing no intensity and 255 representing full intensity. The alpha component specifies the transparency of the color: 0 is fully transparent, and 255 is fully opaque. To determine the alpha, red, green, or blue component of a color, use the xtd::drawing::color::a, xtd::drawing::color::r, xtd::drawing::color::g, or xtd::drawing::color::b property, respectively. You can create a custom color by using one of the xtd::drawing::color::from_argb methods

Examples

The following code example demonstrates the xtd::drawing::color::a, xtd::drawing::color::r, xtd::drawing::color::g, and B properties of a xtd::drawing::color, and the Implicit(size to size_f) member.
This example is designed to be used with a Windows Form (xtd::forms). Paste the code into the form and call the show_properties_of_slate_blue method from the form's xtd::forms::control::paint event-handling method, passing e as xtd::forms::paint_event_args.

void show_properties_of_slate_blue(xtd::forms::paint_event_args& e) {
  color slate_blue = xtd::drawing::color::from_name("slate blue");
  xtd::byte a = slate_blue.a();
  xtd::byte r = slate_blue.r();
  xtd::byte g = slate_blue.g();
  xtd::byte b = slate_blue.b();
  string text = xtd::string::format("Slate blue has these ARGB values: alpha:{0}, red:{1}, green:{2}, blue:{3}", a, r, g, b);
  e.graphics().draw_string(text, xtd::drawing::font(font(), xtd::drawing::font_style::italic), xtd::drawing::solid_brush(slate_blue), xtd::drawing::rectangle_f(xtd::drawing::point_f(0.0f, 0.0f), size()));
}

color()

xtd::drawing::color::color ( )

default

Initialize a new instance of xtd::drawing::color class.

Examples

line.cpp.

Member Function Documentation

a()

auto xtd::drawing::color::a ( ) const -> xtd::byte

nodiscardnoexcept

Gets the alpha component value of this xtd::drawing::color class.

Returns

byte The alpha component value of this xtd::drawing::color.

Remarks

The color of each pixel is represented as a 32-bit number: 8 bits each for alpha, red, green, and blue (ARGB). The alpha component specifies the transparency of the color: 0 is fully transparent, and 255 is fully opaque. Likewise, an xtd::drawing::color::a value of 255 represents an opaque color. An xtd::drawing::color::a value from 1 through 254 represents a semitransparent color. The color becomes more opaque as xtd::drawing::color::a approaches 255.

Examples

The following code example demonstrates the xtd::drawing::color::a, xtd::drawing::color::r, xtd::drawing::color::g, and xtd::drawing::color::b properties of a xtd::drawing::color, and the Implicit(size to size_f) member.
This example is designed to be used with a Windows Form (xtd::forms). Paste the code into the form and call the show_properties_of_slate_blue method from the form's xtd::forms::control::paint event-handling method, passing e as xtd::forms::paint_event_args.

void show_properties_of_slate_blue(xtd::forms::paint_event_args& e) {

  byte r = slate_blue.r();
  byte a = slate_blue.a();
  string text = xtd::string::format("Slate blue has these ARGB values: alpha:{0}, red:{1}, green: {2}, blue {3}", a, r, g, b);
  e.graphics().draw_string(text, xtd::drawing::font(font(), xtd::drawing::font_style::italic), xtd::drawing::solid_brush(slate_blue), xtd::drawing::rectangle_f(xtd::drawing::point_f(0.0f, 0.0f), size()));

Returns

bool Returns true if this xtd::drawing::color was created from a predefined color by using either the from_name method or the from_known_color method; otherwise, false.

Remarks

This property does not do a comparison of the ARGB values. Therefore, when the is_known_color property is applied to a xtd::drawing::color structure that is created by using the xtd::drawing::color::from_argb method, is_known_color returns false, even if the ARGB value matches the ARGB value of a predefined color.

is_light()

Returns

byte The red component value of this xtd::drawing::color.

Remarks

The color of each pixel is represented as a 32-bit number: 8 bits each for alpha, red, green, and blue (ARGB). The alpha component specifies the transparency of the color: 0 is fully transparent, and 255 is fully opaque. Likewise, an xtd::drawing::color::a value of 255 represents an opaque color. An xtd::drawing::color::a value from 1 through 254 represents a semitransparent color. The color becomes more opaque as xtd::drawing::color::a approaches 255.

Examples

Examples

The following code example is designed for use with Windows Forms, and it requires xtd::forms::paint_event_args e, which is a parameter of the xtd::forms::control::paint event handler. The code performs the following actions:

• Iterates through the xtd::drawing::known_color enumeration elements to find all known colors that have a non-zero green component and a zero-value red component, and that are not system colors.
• During each iteration, saves the xtd::drawing::known_color element - if it matches the criteria - in an array.
• Uses a brush to paint rectangles. Each of the rectangles is painted a xtd::drawing::known_color that matches the criteria stated in the first bullet. The name of the xtd::drawing::known_color and its component values are also displayed. This example displays certain known colors, the names of the colors, and their four component values. The xtd::drawing::color::to_argb method is used as a preliminary step to display the component values.

  void to_argb_to_string_example1(paint_event_args& e) {
    graphics g = e.graphics();
    // Color structure used for temporary storage.
    color some_color = color::from_argb(0);
    // Vector to store known_color values that match the criteria.
    xtd::array<known_color> color_matches;
    // Iterate through the KnownColor enums to find all corresponding colors
    // that have a nonzero green component and zero-value red component and
    // that are not system colors.
    for (int enum_value = 0; enum_value <= static_cast<int>(known_color::yellow_green); ++enum_value) {
      some_color = color::from_known_color(static_cast<known_color>(enum_value));
      if (some_color.g() != 0 && some_color.r() == 0 && !some_color.is_system_color())
        color_matches.emplace_back(static_cast<known_color>(enum_value));
    }
    solid_brush my_brush1 {some_color};
    font my_font {"Arial", 9};
    int x = 40;
    int y = 40;
    // Iterate through the matches that were found and display each color that
    // corresponds with the enum value in the array. also display the name of
    // the known_color and the ARGB components.
    for (auto i = 0_z; i < color_matches.length(); ++i) {
      // Display the color.
      some_color = color::from_known_color(color_matches[i]);
      my_brush1.color(some_color);
      g.fill_rectangle(my_brush1, x, y, 50, 30);
      // Display known_color name and the four component values. To display the
      // component values:  Use the to_argb method to get the 32-bit ARGB value
      // of some_color, which was created from a known_color. Then create a
      // color structure from the 32-bit ARGB value and set some_color equal to
      // this new color structure. Then use the to_string method to convert it to
      // a string.
      g.draw_string(some_color.to_string(), my_font, brushes::black(), x + 55, y);
      some_color = color::from_argb(some_color.to_argb());
      g.draw_string(some_color.to_string(), my_font, brushes::black(), x + 55, y + 15);
      y += 40;
    }
  }

to_cmyk()

auto xtd::drawing::color::to_cmyk ( ) const -> xtd::drawing::cmyk

nodiscardnoexcept

Gets the xtd::drawing::cmyk value of this xtd::drawing::color class.

Returns

The xtd::drawing::cmyk value of this xtd::drawing::color.

to_known_color()

auto xtd::drawing::color::to_known_color ( ) const -> xtd::drawing::known_color

nodiscardnoexcept

Gets the xtd::drawing::known_color value of this xtd::drawing::color class.

Returns

xtd::drawing::known_color An element of the xtd::drawing::known_color enumeration, if the xtd::drawing::color is created from a predefined color by using either the xtd::drawing::color::from_name method or the xtd::drawing::color::from_known_color method; otherwise, 0.

Remarks

A predefined color is also called a known color and is represented by an element of the xtd::drawing::known_color enumeration. When the xtd::drawing::color::to_known_color method is applied to a xtd::drawing::color structure that is created by using the FromArgb method, xtd::drawing::color::to_known_color returns 0, even if the ARGB value matches the ARGB value of a predefined color. xtd::drawing::color::to_known_color also returns 0 when it is applied to a xtd::drawing::color structure that is created by using the xtd::drawing::color::from_name method with a string name that is not valid.

Returns

string A string that represents this Size.

Examples

The following code example is designed for use with Windows Forms, and it requires xtd::forms::paint_event_args, which is a parameter of the xtd::forms::control::paint event handler. The code performs the following actions:

• Creates an instance of a xtd::drawing::color structure, redShade, to be used for comparisons.
• Iterates through the xtd::drawing::known_color enumeration elements to find all known colors that have the same lightness as redShade. The iterations are terminated when 15 matches are found or the value of the loop counter is greater than the last xtd::drawing::known_color element.
• During each iteration, saves the xtd::drawing::known_color element—if it matches the criteria—in an array.
• Uses a brush to paint rectangles. The first rectangle is painted the color represented by redShade. Each of the other rectangles is painted a xtd::drawing::known_color that matches the hue of the redShade.

  void known_color_brightness_example2(paint_event_args& e) {
    graphics g = e.graphics();
   
    // xtd::drawing::color structures. One is a variable used for temporary storage. The other is a constant used for comparisons.
    xtd::drawing::color some_color = xtd::drawing::color::from_uint32(0);

Examples

The following code example is designed for use with Windows Forms, and it requires xtd::forms::paint_event_args e, which is a parameter of the xtd::forms::control::paint event handler. The code performs the following actions:

• Creates three brushes, each a different color. Each xtd::drawing::color structure that is used to create a brush is created from four component values (alpha, red, green, blue).
• Uses an imaginary triangle to position three circles.
• Paints three overlapping circles, each centered on one vertex of the triangle, using a different brush for each circle.

  void from_argb1(paint_event_args& e) {
    graphics g = e.graphics();
   
    // Transparent red, green, and blue brushes.
    solid_brush trns_red_brush(color::from_argb(0x78FF0000));
    solid_brush trns_green_brush(color::from_argb(0x7800FF00));
    solid_brush trns_blue_brush(color::from_argb(0x780000FF));
   
    // Base and height of the triangle that is used to position the circles. Each vertex of the triangle is at the center of one of the 3 circles. The base is equal to the diameter of the circles.
    float tri_base = 100;
    float tri_height = std::sqrt(3 * (tri_base * tri_base) / 4);
   
    // Coordinates of first circle's bounding rectangle.
    float x1 = 40;
    float y1 = 40;
   
    // Fill 3 over-lapping circles. Each circle is a different color.
    g.fill_ellipse(trns_red_brush, x1, y1, 2 * tri_height, 2 * tri_height);
    g.fill_ellipse(trns_green_brush, x1 + tri_base / 2, y1 + tri_height, 2 * tri_height, 2 * tri_height);
    g.fill_ellipse(trns_blue_brush, x1 + tri_base, y1, 2 * tri_height, 2 * tri_height);

from_argb() [2/5]

auto xtd::drawing::color::from_argb ( xtd::byte alpha, const xtd::drawing::color & base_color ) -> xtd::drawing::color

staticnodiscardnoexcept

Creates a xtd::drawing::color class from the specified xtd::drawing::color structure, but with the new specified alpha value. Although this method allows a 32-bit value to be passed for the alpha value, the value is limited to 8 bits.

Parameters

alpha	The alpha value for the new xtd::drawing::color. Valid values are 0 through 255.
base_color	The xtd::drawing::color from which to create the new xtd::drawing::color.

Returns

xtd::drawing::color The xtd::drawing::color structure that this method creates.

Examples

The following code example is designed for use with Windows Forms, and it requires xtd::forms::paint_event_args e, which is a parameter of the xtd::forms::control::paint event handler. The code performs the following actions:

• Creates xtd::drawing::color structures from the three color component values (red, green, blue). Three xtd::drawing::color structures are created, one for each primary color.
• Iterates through a range of alpha values, changing the alpha value of a color.
• During each iteration, sets the color of a brush to the modified color and paints a rectangle to show the color.
• Repeats steps 2 and 3 for each primary color. The alpha value is never fully opaque and the rectangles overlap so you get color-combination effects.

  void from_argb2(paint_event_aArgs& e) {
    graphics g = e.graphics();
   
    // Opaque colors (alpha value defaults to 255 -- max value).
    color red = color::from_argb(255, 0, 0);
    color green = color::from_argb(0, 255, 0);
    color blue = color::from_argb(0, 0, 255);
   
    // Solid brush initialized to red.

Examples

The following code example is designed for use with Windows Forms, and it requires xtd::forms::paint_event_args, which is a parameter of the xtd::forms::control::paint event handler. The code performs the following actions:

• Creates an instance of a xtd::drawing::color structure, redShade, to be used for comparisons.
• Iterates through the xtd::drawing::known_color enumeration elements to find all known colors that have the same lightness as redShade. The iterations are terminated when 15 matches are found or the value of the loop counter is greater than the last xtd::drawing::known_color element.
• During each iteration, saves the xtd::drawing::known_color element—if it matches the criteria—in an array.
• Uses a brush to paint rectangles. The first rectangle is painted the color represented by redShade. Each of the other rectangles is painted a xtd::drawing::known_color that matches the hue of the redShade.

from_name()

auto xtd::drawing::color::from_name ( const xtd::string & name ) -> xtd::drawing::color

staticnodiscardnoexcept

Creates a xtd::drawing::color class from the specified name of a predefined color.

Parameters

name	A string that is the name of a predefined color. Valid names are the same as the names of the elements of the xtd::drawing::known_color enumeration.

Returns

xtd::drawing::color The xtd::drawing::color structure that this method creates.

Remarks

A predefined color is also called a known color and is represented by an element of the xtd::drawing::known_color enumeration. If the name parameter is not the valid name of a predefined color, the xtd::drawing::color::from_name method creates a xtd::drawing::color structure that has an ARGB value of 0 (that is, all ARGB components are 0).

Examples

The following code example demonstrates the xtd::drawing::color::a, xtd::drawing::color::r, xtd::drawing::color::g, and xtd::drawing::color::b properties of a xtd::drawing::color, and the Implicit(size to size_f) member.
This example is designed to be used with a Windows Form (xtd::forms). Paste the code into the form and call the show_properties_of_slate_blue method from the form's xtd::forms::control::paint event-handling method, passing e as xtd::forms::paint_event_args.

void show_properties_of_slate_blue(xtd::forms::paint_event_args& e) {
  color slate_blue = xtd::drawing::color::from_name("slate blue");
  byte g = slate_blue.g();
  byte b = slate_blue.b();
  byte r = slate_blue.r();
  byte a = slate_blue.a();
  string text = xtd::string::format("Slate blue has these ARGB values: alpha:{0}, red:{1}, green: {2}, blue {3}", a, r, g, b);
  e.graphics().draw_string(text, xtd::drawing::font(font(), xtd::drawing::font_style::italic), xtd::drawing::solid_brush(slate_blue), xtd::drawing::rectangle_f(xtd::drawing::point_f(0.0f, 0.0f), size()));
}
