53 \class QColor -

54 \brief The QColor class provides colors based on RGB, HSV or CMYK values. -

55 -

56 \ingroup painting -

57 \ingroup appearance -

58 \inmodule QtGui -

59 -

60 -

61 A color is normally specified in terms of RGB (red, green, and -

62 blue) components, but it is also possible to specify it in terms -

63 of HSV (hue, saturation, and value) and CMYK (cyan, magenta, -

64 yellow and black) components. In addition a color can be specified -

65 using a color name. The color name can be any of the SVG 1.0 color -

66 names. -

67 -

68 \table -

69 \header -

70 \li RGB \li HSV \li CMYK -

71 \row -

72 \li \inlineimage qcolor-rgb.png -

73 \li \inlineimage qcolor-hsv.png -

74 \li \inlineimage qcolor-cmyk.png -

75 \endtable -

76 -

77 The QColor constructor creates the color based on RGB values. To -

78 create a QColor based on either HSV or CMYK values, use the -

79 toHsv() and toCmyk() functions respectively. These functions -

80 return a copy of the color using the desired format. In addition -

81 the static fromRgb(), fromHsv() and fromCmyk() functions create -

82 colors from the specified values. Alternatively, a color can be -

83 converted to any of the three formats using the convertTo() -

84 function (returning a copy of the color in the desired format), or -

85 any of the setRgb(), setHsv() and setCmyk() functions altering \e -

86 this color's format. The spec() function tells how the color was -

87 specified. -

88 -

89 A color can be set by passing an RGB string (such as "#112233"), -

90 or an ARGB string (such as "#ff112233") or a color name (such as "blue"), -

91 to the setNamedColor() function. -

92 The color names are taken from the SVG 1.0 color names. The name() -

93 function returns the name of the color in the format -

94 "#RRGGBB". Colors can also be set using setRgb(), setHsv() and -

95 setCmyk(). To get a lighter or darker color use the lighter() and -

96 darker() functions respectively. -

97 -

98 The isValid() function indicates whether a QColor is legal at -

99 all. For example, a RGB color with RGB values out of range is -

100 illegal. For performance reasons, QColor mostly disregards illegal -

101 colors, and for that reason, the result of using an invalid color -

102 is undefined. -

103 -

104 The color components can be retrieved individually, e.g with -

105 red(), hue() and cyan(). The values of the color components can -

106 also be retrieved in one go using the getRgb(), getHsv() and -

107 getCmyk() functions. Using the RGB color model, the color -

108 components can in addition be accessed with rgb(). -

109 -

110 There are several related non-members: QRgb is a typdef for an -

111 unsigned int representing the RGB value triplet (r, g, b). Note -

112 that it also can hold a value for the alpha-channel (for more -

113 information, see the \l {QColor#Alpha-Blended -

114 Drawing}{Alpha-Blended Drawing} section). The qRed(), qBlue() and -

115 qGreen() functions return the respective component of the given -

116 QRgb value, while the qRgb() and qRgba() functions create and -

117 return the QRgb triplet based on the given component -

118 values. Finally, the qAlpha() function returns the alpha component -

119 of the provided QRgb, and the qGray() function calculates and -

120 return a gray value based on the given value. -

121 -

122 QColor is platform and device independent. The QColormap class -

123 maps the color to the hardware. -

124 -

125 For more information about painting in general, see the \l{Paint -

126 System} documentation. -

130 \section1 Integer vs. Floating Point Precision -

131 -

132 QColor supports floating point precision and provides floating -

133 point versions of all the color components functions, -

134 e.g. getRgbF(), hueF() and fromCmykF(). Note that since the -

135 components are stored using 16-bit integers, there might be minor -

136 deviations between the values set using, for example, setRgbF() -

137 and the values returned by the getRgbF() function due to rounding. -

138 -

139 While the integer based functions take values in the range 0-255 -

140 (except hue() which must have values within the range 0-359), -

141 the floating point functions accept values in the range 0.0 - 1.0. -

142 -

143 \section1 Alpha-Blended Drawing -

144 -

145 QColor also support alpha-blended outlining and filling. The -

146 alpha channel of a color specifies the transparency effect, 0 -

147 represents a fully transparent color, while 255 represents a fully -

148 opaque color. For example: -

149 -

150 \snippet code/src_gui_painting_qcolor.cpp 0 -

151 -

152 The code above produces the following output: -

153 -

154 \image alphafill.png -

155 -

156 The alpha channel of a color can be retrieved and set using the -

157 alpha() and setAlpha() functions if its value is an integer, and -

158 alphaF() and setAlphaF() if its value is qreal (double). By -

159 default, the alpha-channel is set to 255 (opaque). To retrieve and -

160 set \e all the RGB color components (including the alpha-channel) -

161 in one go, use the rgba() and setRgba() functions. -

162 -

163 \section1 Predefined Colors -

164 -

165 There are 20 predefined QColors described by the Qt::GlobalColor enum, -

166 including black, white, primary and secondary colors, darker versions -

167 of these colors and three shades of gray. QColor also recognizes a -

168 variety of color names; the static colorNames() function returns a -

169 QStringList color names that QColor knows about. -

170 -

171 \image qt-colors.png Qt Colors -

172 -

173 Additionally, the Qt::color0, Qt::color1 and Qt::transparent colors -

174 are used for special purposes. -

175 -

176 Qt::color0 (zero pixel value) and Qt::color1 (non-zero pixel value) -

177 are special colors for drawing in QBitmaps. Painting with Qt::color0 -

178 sets the bitmap bits to 0 (transparent; i.e., background), and painting -

179 with Qt::color1 sets the bits to 1 (opaque; i.e., foreground). -

180 -

181 Qt::transparent is used to indicate a transparent pixel. When painting -

182 with this value, a pixel value will be used that is appropriate for the -

183 underlying pixel format in use. -

184 -

185 \section1 The HSV Color Model -

186 -

187 The RGB model is hardware-oriented. Its representation is close to -

188 what most monitors show. In contrast, HSV represents color in a way -

189 more suited to the human perception of color. For example, the -

190 relationships "stronger than", "darker than", and "the opposite of" -

191 are easily expressed in HSV but are much harder to express in RGB. -

192 -

193 HSV, like RGB, has three components: -

194 -

195 \list -

196 \li H, for hue, is in the range 0 to 359 if the color is chromatic (not -

197 gray), or meaningless if it is gray. It represents degrees on the -

198 color wheel familiar to most people. Red is 0 (degrees), green is -

199 120, and blue is 240. -

200 -

201 \inlineimage qcolor-hue.png -

202 -

203 \li S, for saturation, is in the range 0 to 255, and the bigger it is, -

204 the stronger the color is. Grayish colors have saturation near 0; very -

205 strong colors have saturation near 255. -

206 -

207 \inlineimage qcolor-saturation.png -

208 -

209 \li V, for value, is in the range 0 to 255 and represents lightness or -

210 brightness of the color. 0 is black; 255 is as far from black as -

211 possible. -

212 -

213 \inlineimage qcolor-value.png -

214 \endlist -

215 -

216 Here are some examples: pure red is H=0, S=255, V=255; a dark red, -

217 moving slightly towards the magenta, could be H=350 (equivalent to -

218 -10), S=255, V=180; a grayish light red could have H about 0 (say -

219 350-359 or 0-10), S about 50-100, and S=255. -

220 -

221 Qt returns a hue value of -1 for achromatic colors. If you pass a -

222 hue value that is too large, Qt forces it into range. Hue 360 or 720 is -

223 treated as 0; hue 540 is treated as 180. -

224 -

225 In addition to the standard HSV model, Qt provides an -

226 alpha-channel to feature \l {QColor#Alpha-Blended -

227 Drawing}{alpha-blended drawing}. -

228 -

229 \section1 The HSL Color Model -

230 -

231 HSL is similar to HSV. Instead of value parameter from HSV, -

232 HSL has the lightness parameter. -

233 The lightness parameter goes from black to color and from color to white. -

234 If you go outside at the night its black or dark gray. At day its colorful but -

235 if you look in a really strong light a things they are going to white and -

236 wash out. -

237 -

238 \section1 The CMYK Color Model -

239 -

240 While the RGB and HSV color models are used for display on -

241 computer monitors, the CMYK model is used in the four-color -

242 printing process of printing presses and some hard-copy -

243 devices. -

244 -

245 CMYK has four components, all in the range 0-255: cyan (C), -

246 magenta (M), yellow (Y) and black (K). Cyan, magenta and yellow -

247 are called subtractive colors; the CMYK color model creates color -

248 by starting with a white surface and then subtracting color by -

249 applying the appropriate components. While combining cyan, magenta -

250 and yellow gives the color black, subtracting one or more will -

251 yield any other color. When combined in various percentages, these -

252 three colors can create the entire spectrum of colors. -

253 -

254 Mixing 100 percent of cyan, magenta and yellow \e does produce -

255 black, but the result is unsatisfactory since it wastes ink, -

256 increases drying time, and gives a muddy colour when printing. For -

257 that reason, black is added in professional printing to provide a -

258 solid black tone; hence the term 'four color process'. -

259 -

260 In addition to the standard CMYK model, Qt provides an -

261 alpha-channel to feature \l {QColor#Alpha-Blended -

262 Drawing}{alpha-blended drawing}. -
