CurveType property (ILEADRaster)

Visual Basic example

Visual C++ 5.0 example

 

Syntax

CurveTypeConstants CurveType;

Overview

Refer to Creating and Using a Bitmap Region

Remarks

Indicates the type of curve defined by the array of points specified in the CurveX property and the CurveY property. Possible values are:

Value

Meaning

CURVE_BEZIER

The points specified in the CurveX and CurveY properties define a Bezier curve.

CURVE_STANDARD

The points specified in the CurveX and CurveY properties define a standard curve.

This property must be set to CURVE_STANDARD to use the CurveX and CurveY arrays with the CurveToBezier method.

To create a curve region, first build an ordered array of points for the curve. Then create the region based on the array. The CurveSize property specifies the size of the array. Either specify a large array to start with, or increase the size of the array as needed, without losing existing points. For each point, update the following indexed properties:

image\sqrblit.gif CurveX property

image\sqrblit.gif CurveY property

And define the characteristics of the curve by setting the following properties:

image\sqrblit.gif CurveType property

image\sqrblit.gif CurveTension property

image\sqrblit.gif CurveClose property

Then call the SetRgnCurve method to add the region to the bitmap.
