Detailed Description
an abstract base class for various style classes
A GeoDataColorStyle is an abstract class that is the base class for a number of different style classes. It provides settings for specifying the color and color mode of the extended style classes. A GeoDataColorStyle should never be instantiated directly.
The color contains RGBA, (Red, Green, Blue, Alpha). Color and opacity (alpha) values have a range of 0 to 255 (00 to ff). For alpha, 00 is fully transparent and ff is fully opaque. For example, if you want to apply a blue color with 50 percent opacity to an overlay, you would specify the following: 7fff0000, where alpha=0x7f, blue=0xff, green=0x00, and red=0x00.
The color mode can either be normal (no effect) or random. A value of random applies a random linear scale to the base color as follows.
To achieve a truly random selection of colors, specify a base color of white (ffffffff). If you specify a single color component (for example, a value of ff0000ff for red), random color values for that one component (red) will be selected. In this case, the values would range from 00 (black) to ff (full red). If you specify values for two or for all three color components, a random linear scale is applied to each color component, with results ranging from black to the maximum values specified for each component. The opacity of a color comes from the alpha component of color and is never randomized.

Return the color component.
Definition at line 90 of file GeoDataColorStyle.cpp.
◆ colorMode()
GeoDataColorStyle::ColorMode Marble::GeoDataColorStyle::colorMode | ( | ) | const |
Return the color mode.
Definition at line 105 of file GeoDataColorStyle.cpp.
◆ contrastColor()
- Returns
- Returns a foreground color suitable for e.g. text display on top of the given background color
Definition at line 128 of file GeoDataColorStyle.cpp.
◆ nodeType()
|
overridevirtual |
Provides type information for downcasting a GeoData.
Implements Marble::GeoNode.
Reimplemented in Marble::GeoDataLabelStyle, Marble::GeoDataLineStyle, and Marble::GeoDataPolyStyle.

assignment operator
- Parameters
-
other the other colorstyle
Definition at line 54 of file GeoDataColorStyle.cpp.
◆ operator==()
bool Marble::GeoDataColorStyle::operator== | ( | const GeoDataColorStyle & | other | ) | const |
Definition at line 61 of file GeoDataColorStyle.cpp.
◆ pack()
|
override |
Serialize the style to a stream.
- Parameters
-
stream the stream
Definition at line 110 of file GeoDataColorStyle.cpp.
◆ paintedColor()
QColor Marble::GeoDataColorStyle::paintedColor | ( | ) | const |
Returns the color that should be painted: Either color() or a randomized version of it, depending on the colorMode() setting.
Randomization happens once per setColor() call, i.e. repeated calls to paintedColor always return the same color unless setColor is called in between.
Definition at line 95 of file GeoDataColorStyle.cpp.
◆ setColor()
void Marble::GeoDataColorStyle::setColor | ( | const QColor & | value | ) |
Set a new color.
- Parameters
-
value the new color value
Definition at line 76 of file GeoDataColorStyle.cpp.
◆ setColorMode()
void Marble::GeoDataColorStyle::setColorMode | ( | ColorMode | colorMode | ) |
Set a new color mode.
- Parameters
-
colorMode the new color mode value
Definition at line 100 of file GeoDataColorStyle.cpp.
◆ unpack()
|
override |
Unserialize the style from a stream.
- Parameters
-
stream the stream
