Graphics Palette

The following object creation modes are available in the Graphics palette.

Use this mode to draw an IlvReliefLine object. After selecting this mode, press the left mouse button to indicate the first point, drag the cursor to the second point, and release the mouse button to complete the operation.

Use this mode to draw an IlvLine object. After selecting this mode, press the left mouse button to indicate the first point, drag the cursor to the second point, and release the mouse button to complete the operation.

Use this mode to draw an IlvArrowLine object. After selecting this mode, press the left mouse button to indicate the first node, drag the cursor to the second node, and release the mouse button to complete the operation.

Use this mode to draw an IlvArc object.

Use this mode to draw an IlvFilledArc object in the same way as described for using arc mode.

Use this mode to draw an IlvPolyline object. After selecting this mode, click in the work space to indicate the points in the order you want them to be in the polyline.

Press the mouse button and drag the pointer and release the mouse to add a point to your polyline.

Press the spacebar or enter key to end the creation of your polyline. Alternatively, you can double click to end the operation, but this may result in extraneous points being added to the polyline, as a slow double click is interpreted as consecutive clicks, and therefore adds two points to the polyline.

Use this mode to draw an IlvPolygon object. After selecting this mode, click in the work space to indicate the points in the order you want them to be in the polygon.

Press the mouse button and drag the pointer and release the mouse to add a point to your polygon.

Press the spacebar or enter key to end the creation of your polygon. Alternatively, you can double click to end the operation, but this may result in extraneous points being added to the polygon, as a slow double click is interpreted as consecutive clicks, and therefore adds two points to the polygon.

Use this mode to draw an IlvSpline object. After selecting this mode, click in the work space to indicate the points in the order you want them to be in the spline. See Creating Bezier curves (open, closed and filled splines).

Use this mode to draw an IlvClosedSpline object. After selecting this mode, click in the work space to indicate the points in the order you want them to be in the closed spline. See Creating Bezier curves (open, closed and filled splines).

Use this mode to draw an IlvFilledSpline object. After selecting this mode, click in the work space to indicate the points in the order you want them to be in the filled spline. Double-click to complete the operation. See Creating Bezier curves (open, closed and filled splines).

Press the mouse button and drag the pointer and release the mouse to add a point and define its tangents and tension at that point.

Press the Ctrl key while dragging a tangent handle to create a cusp at the Bezier curve's position and dissociate the left and right tangents and tensions at that point.

Press the spacebar or enter key to end the creation of your curve. Alternatively, you can double click to end a curve, but this may result in extraneous points being added to the curve, as a slow double click is interpreted as consecutive clicks, and therefore adds two points to the curve.

The Graphics palette contains other objects that can be created using the normal creation mode or drag-and-drop operation.
