Constructor & Destructor Documentation¶
SbColor4f::SbColor4f (void)¶
Default constructor. The color value will be uninitialized until explicitly set.SbColor4f::SbColor4f (const SbColor &rgb, const floatalpha = 1.0f)¶
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 *constrgba)¶
Construct and initialize an SbColor4f with the red, green, blue and alpha taken from given rgba arraySbColor4f::SbColor4f (const floatr, const floatg, const floatb, const floata = 1.0f)¶
Construct and initialize an SbColor4f with the given red, green, blue and alpha values.Member Function Documentation¶
void SbColor4f::setValue (const floatr, const floatg, const floatb, const floata = 1.0f)¶
Set a new color. Reimplemented from SbVec4f.void SbColor4f::setValue (const floatcol[4])¶
Set a new color. The elements of the array will be read in turned as red, green, blue and transparency. Reimplemented from SbVec4f.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. Reimplemented from SbVec4f.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 (floathue, floatsaturation, floatvalue, floatalpha = 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:getHSVValue().
SbColor4f & SbColor4f::setHSVValue (const floathsv[3], floata = 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:getHSVValue().
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:setHSVValue().
void SbColor4f::getHSVValue (floathsv[3]) const¶
Return the color as a hue, saturation, value triplet. Alpha component is ignored. See Also:setHSVValue().
SbColor4f & SbColor4f::setPackedValue (const uint32_trgba)¶
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:getPackedValue().
uint32_t SbColor4f::getPackedValue () const¶
Return color as a 32 bit packed integer in the form 0xRRGGBBAA. See Also:setPackedValue().
float SbColor4f::operator[] (const intidx) 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. Reimplemented from SbVec4f.float & SbColor4f::operator[] (const intidx)¶
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. Reimplemented from SbVec4f.SbColor4f & SbColor4f::operator*= (const floatd)¶
Multiplies the RGB components by d. The alpha component is left unchanged. Reimplemented from SbVec4f.SbColor4f & SbColor4f::operator/= (const floatd)¶
Divides the RGB components by d. The alpha component is left unchanged. Reimplemented from SbVec4f.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.Friends And Related Function Documentation¶
SbColor4f operator* (const SbColor4f &c, const floatd) [friend]¶
Multiplies the RGB components by d. Alpha is left unchanged.SbColor4f operator* (const floatd, const SbColor4f &c) [friend]¶
Multiplies the RGB components by d. Alpha is left unchanged.SbColor4f operator/ (const SbColor4f &c, const floatd) [friend]¶
Divides the RGB components by d. Alpha is left unchanged.SbColor4f operator+ (const SbColor4f &v1, const SbColor4f &v2) [friend]¶
Adds the RGB components of the two colors. Alpha is taken from the first color (v1).SbColor4f operator- (const SbColor4f &v1, const SbColor4f &v2) [friend]¶
Subtracts the RGB components of the two colors. Alpha is taken from the first color (v1).int operator== (const SbColor4f &v1, const SbColor4f &v2) [friend]¶
Check if two colors are equal. Returns 1 if equal, 0 if unequal.int operator!= (const SbColor4f &v1, const SbColor4f &v2) [friend]¶
Check if two colors are unequal. Returns 0 if equal, 1 if unequal.Author¶
