Parameters

point

Type: System.Drawing.PointF

PointF structure specifying the point to start filling from.

brush

Type: Aurigma.GraphicsMill.Drawing.Brush

Brush class instance used to fill the surface. Currently only SolidBrush is supported.

targetColor

Type: Aurigma.GraphicsMill.Color

The Color which is used to determine the filling area boundaries. The method behaviour depends on mode argument value. If mode is UntilColor, this is a boundary color (when algorithm meets this color, it stops filling). If mode is TillColor, this is a surface color (algorithm continue filling till current color is the same as target color).

mode

Type: Aurigma.GraphicsMill.Transforms.FloodFillMode

FloodFillMode value specifying how to determine the filling area boundary (see comments for targetColor).

tolerance

Type: System.Single

Value in range [0, 1] specifying admissible tolerance (distance between colors in color space) when comparing current color and target color (see comments for targetColor). Minimum value (0) means exact match of the colors, maximum value (1) means that any color matches.

preserveAlpha

Type: System.Boolean

Value specifying if to preserve alpha channel. If true, alpha channel will not be overwritten by the colors defined by filling brush.

processHalftones

Type: System.Boolean

Value specifying how to handle situations when current color does not exactly match target color, but tolerant to it (with specified tolerance). If false, this pixel is replaced with brush color, if true, it is alpha-blended (alpha is calculated as 1 - T, where T is actual tolerance between these colors).
