ConvertStops()

void impeller::Paint::ConvertStops ( const flutter::DlGradientColorSourceBase *  gradient, std::vector< Color > &  colors, std::vector< float > &  stops  )

static

Convert display list colors + stops into impeller colors and stops, taking care to ensure that the stops monotonically increase from 0.0 to 1.0.

The general process is:

• Ensure that the first gradient stop value is 0.0. If not, insert a new stop with a value of 0.0 and use the first gradient color as this new stops color.
• Ensure the last gradient stop value is 1.0. If not, insert a new stop with a value of 1.0 and use the last gradient color as this stops color.
• Clamp all gradient values between the values of 0.0 and 1.0.
• For all stop values, ensure that the values are monotonically increasing by clamping each value to a minimum of the previous stop value and itself. For example, with stop values of 0.0, 0.5, 0.4, 1.0, we would clamp such that the values were 0.0, 0.5, 0.5, 1.0.
