SbColor4f::SbColor4f (void)¶

Default constructor. The color value will be uninitialized until explicitly set.

SbColor4f::SbColor4f (const SbColor & rgb, const float alpha)¶

Construct and initialize an SbColor4f with the red, green and blue components from the SbColor rgb, and the alpha value from the supplied alpha argument.

SbColor4f::SbColor4f (const SbVec4f & v)¶

Construct and initialize an SbColor4f with the red, green, blue and alpha values given by the v vector.

SbColor4f::SbColor4f (const float *const rgba)¶

Construct and initialize an SbColor4f with the red, green, blue and alpha taken from given rgba array

SbColor4f::SbColor4f (const float r, const float g, const float b, const float a = 1.0f)¶

Construct and initialize an SbColor4f with the given red, green, blue and alpha values.

void SbColor4f::setValue (const float r, const float g, const float b, const float a = 1.0f)¶

Set a new color.

void SbColor4f::setValue (const float col[4])¶

Set a new color. The elements of the array will be read in turned as red, green, blue and transparency.

const float * SbColor4f::getValue (void) const¶

Return pointer to array of 4 float values representing the red, green, blue and transparency values of the color.

void SbColor4f::getValue (float & r, float & g, float & b, float & a)¶

Return components of the stored color.

SbColor4f & SbColor4f::setRGB (const SbColor & col)¶

Sets the RGB components of the color. The alpha component is left unchanged.

void SbColor4f::getRGB (SbColor & color)¶

Returns the RGB components of this color.

SbColor4f & SbColor4f::setHSVValue (float hue, float saturation, float value, float alpha = 1.0f)¶

Set the color as a hue, saturation, value triplet. The hue component should be normalized to within [0, 1] before you call this method, where 0 is equal to 0° and 1 is equal to 360°.

See also

SbColor4f & SbColor4f::setHSVValue (const float hsv[3], float a = 1.0f)¶

Set the color as a hue, saturation, value triplet. The hue component should be normalized to within [0, 1] before you call this method, where 0 is equal to 0° and 1 is equal to 360°.

See also

void SbColor4f::getHSVValue (float & h, float & s, float & v) const¶

Return the color as a hue, saturation, value triplet. Alpha component is ignored.

See also

void SbColor4f::getHSVValue (float hsv[3]) const¶

Return the color as a hue, saturation, value triplet. Alpha component is ignored.

See also

SbColor4f & SbColor4f::setPackedValue (const uint32_t rgba)¶

Set the color value as a 32 bit combined red/green/blue/alpha value. Each component is 8 bit wide (i.e. from 0x00 to 0xff), and the red value should be stored leftmost, like this: 0xRRGGBBAA.

See also

uint32_t SbColor4f::getPackedValue () const¶

Return color as a 32 bit packed integer in the form 0xRRGGBBAA.

See also

float SbColor4f::operator[] (const int idx) const¶

Returns the color component represented by the given index idx. 0 is red, 1 is green, 2 is blue and 3 is the transparency value.

float & SbColor4f::operator[] (const int idx)¶

Returns the color component represented by the given index idx. 0 is red, 1 is green, 2 is blue and 3 is the transparency value.

SbColor4f & SbColor4f::operator*= (const float d)¶

Multiplies the RGB components by d. The alpha component is left unchanged.

SbColor4f & SbColor4f::operator/= (const float d)¶

Divides the RGB components by d. The alpha component is left unchanged.

SbColor4f & SbColor4f::operator+= (const SbColor4f & c)¶

Adds the RGB components. Alpha is ignored.

SbColor4f & SbColor4f::operator-= (const SbColor4f & c)¶

Subtracts the RGB components. Alpha is ignored.
