Test color gradient with VG_PAINT_COLOR_RAMP_PREMULTIPLIED disabled, VG_COLOR_RAMP_SPREAD_PAD spread mode, VG_COLOR_TRANSFORM disabled, alpha-premultiplied drawing surface | The test sets a valid VG_PAINT_COLOR_RAMP_STOPS array with multiple stops having the same offset. According to OpenVG specifications it is legal to have multiple stops with the same offset value, which will result in a discontinuity in the color ramp, with the first stop with a given offset value defining the right endpoint of one interval and the last stop with the same offset value defining the left endpoint of the next interval |

Test color gradient with VG_PAINT_COLOR_RAMP_PREMULTIPLIED disabled, VG_COLOR_RAMP_SPREAD_REPEAT spread mode, VG_COLOR_TRANSFORM disabled, alpha-premultiplied drawing surface | The test sets a NULL VG_PAINT_COLOR_RAMP_STOPS array, so according to OpenVG specifications, two implicit color stops are added: an opaque black at offset 0 and an opaque white at offset 1. For this gradient in VG_COLOR_RAMP_SPREAD_REPEAT mode, at the gradient end points a sharp transition white-black is the expected behaviour; the Khronos reference implementation performs a filtering on the gradient, so at sharp transitions it shows an intermediate artifact color (a grey). This is particularly noticeable (RMS-wide) on B/W gradients |

Test color gradient with VG_PAINT_COLOR_RAMP_PREMULTIPLIED disabled, VG_COLOR_RAMP_SPREAD_REFLECT spread mode, VG_COLOR_TRANSFORM enabled, alpha-premultiplied drawing surface | The test sets a valid VG_PAINT_COLOR_RAMP_STOPS array with multiple stops having the same offset. According to OpenVG specifications it is legal to have multiple stops with the same offset value, which will result in a discontinuity in the color ramp, with the first stop with a given offset value defining the right endpoint of one interval and the last stop with the same offset value defining the left endpoint of the next interval |

For this gradient in VG_COLOR_RAMP_SPREAD_REPEAT mode, at the gradient end points a sharp transition white-black is the expected behaviour; the Khronos reference implementation performs a filtering on the gradient, so at sharp transitions it shows an intermediate artifact color (a grey). This is particularly noticeable (RMS-wide) on B/W gradients |
