Initializes a new instance of the AxialShading class.

	double[] coords,
	double[] domain,
	string[] functionResourceIds


Type: SystemString
The resource id.
Type: SystemString
The color space resource ID. The colour space in which colour values shall beexpressed. This may be any device, CIE-based, or special colour space except a Pattern space.
Type: Apitron.PDF.Kit.FixedLayoutBoundary
An array of four numbers giving the left, bottom, right, and top coordinates, respectively, of the shading’s bounding box. The coordinates shall be interpreted in the shading’s target coordinate space. If present, this bounding box shall be applied as a temporary clipping boundary when the shading is painted, in addition to the current clipping path and any other clipping boundaries in effect at that time.
Type: SystemDouble
An array of colour components appropriate to the colour space, specifying a single background colour value. If present, this colour shall be used, before any painting operation involving the shading, to fill those portions of the area to be painted that lie outside the bounds of the shading object.
Type: SystemDouble
An array of four numbers [x0 y0 x1 y1] specifying the starting and ending coordinates of the axis, expressed in the shading’s target coordinate space.
Type: SystemDouble
An array of two numbers [t0 t1] specifying the limiting values of a parametric variable t. The variable is considered to vary linearly between these two values as the colour gradient varies between the starting and ending points of the axis. The variable t becomes the input argument to the colour function(s). Default value: [0.0 1.0].
Type: SystemString
A 1-in, n-out function or an array of n 1-in, 1-out functions (where n is the number of colour components in the shading dictionary’s colour space). The function(s) shall be called with values of the parametric variable t in the domain defined by the Domain entry. Each function’s domain shall be a superset of that of the shading dictionary. If the value returned by the function for a given colour component is out of range, it shall be adjusted to the nearest valid value.
