 org.eclipse.ui.internal.themes.RGBContrastFactory
| RGBContrastFactory | | public class RGBContrastFactory implements IColorFactory,IExecutableExtension(Code) | | A IColorFactory that may be used to select a colour with
a higher contrast. The colors to blend are specified as per method
number two in
org.eclipse.core.runtime.IExecutableExtension .
Example usage:
<colorDefinition
label="Red/Blue Contrast"
id="example.redblueblend">
<colorFactory
plugin="org.eclipse.ui"
class="org.eclipse.ui.internal.themes.RGBContrastFactory">
<parameter name="foreground" value="0,0,0" />
<parameter name="background1" value="COLOR_RED" />
<parameter name="background2" value="COLOR_BLUE" />
</colorFactory>
</colorDefinition>
This will select whichever of Red or Blue has a higher contrst with black.
The color values may be specified as RGB triples or as SWT constants.

| Method Summary | |
| public RGB | createColor()
| | double | lightness(RGB color)
Returns a measure of the lightness in the perceptual colourspace
IPT. | | public void | setInitializationData(IConfigurationElement config, String propertyName, Object data)
This executable extension requires parameters to be explicitly declared
via the second method described in the IExecutableExtension
documentation. | | double | voltage_to_intensity_srgb(double val)
Returns the intensity of an RGB component using the
sRGB gamma function.
Parameters:
val - Value to convert. |
| createColor | | public RGB createColor()(Code) | | |
| lightness | | double lightness(RGB color)(Code) | | Returns a measure of the lightness in the perceptual colourspace
IPT.
Parameters:
color - The colour in sRGB Lightness in IPT space. |
| setInitializationData | | public void setInitializationData(IConfigurationElement config, String propertyName, Object data) throws CoreException(Code) | | This executable extension requires parameters to be explicitly declared
via the second method described in the IExecutableExtension
documentation. This class expects that there will be three parameters,
foreground, background1 and
background2, that describe the two colors to be blended.
These values may either be RGB triples or SWT constants.

| voltage_to_intensity_srgb | | double voltage_to_intensity_srgb(double val)(Code) | | Returns the intensity of an RGB component using the
sRGB gamma function.
Parameters:
val - Value to convert. Light intensity of the component. |
