Lines Matching defs:angle
48 * This type is used to model angle values in FreeType. Note that the
49 * angle is a 16.16 fixed-point value expressed in degrees.
61 * The angle pi expressed in @FT_Angle units.
73 * The angle 2*pi expressed in @FT_Angle units.
85 * The angle pi/2 expressed in @FT_Angle units.
97 * The angle pi/4 expressed in @FT_Angle units.
109 * Return the sinus of a given angle in fixed-point format.
112 * angle ::
113 * The input angle.
119 * If you need both the sinus and cosinus for a given angle, use the
124 FT_Sin( FT_Angle angle );
133 * Return the cosinus of a given angle in fixed-point format.
136 * angle ::
137 * The input angle.
143 * If you need both the sinus and cosinus for a given angle, use the
148 FT_Cos( FT_Angle angle );
157 * Return the tangent of a given angle in fixed-point format.
160 * angle ::
161 * The input angle.
168 FT_Tan( FT_Angle angle );
188 * The arc-tangent value (i.e. angle).
207 * First angle.
210 * Second angle.
227 * Return the unit vector corresponding to a given angle. After the
228 * call, the value of `vec.x' will be `sin(angle)', and the value of
229 * `vec.y' will be `cos(angle)'.
232 * given angle quickly.
239 * angle ::
240 * The address of angle.
245 FT_Angle angle );
254 * Rotate a vector by a given angle.
261 * angle ::
262 * The address of angle.
267 FT_Angle angle );
297 * Compute both the length and angle of a given vector.
307 * angle ::
308 * The vector angle.
314 FT_Angle *angle );
323 * Compute vector coordinates from a length and angle.
333 * angle ::
334 * The vector angle.
340 FT_Angle angle );
