Ink Graphic Object.

Remarks

The InkGraphic Element is used for TabletPC support and is the element used to persist and draw ink graphics. An InkGraphic implements the IElement interface, and you can use the IInkGraphic interface to get ink-specific properties for the element. Ink graphics are one of two types-Pen Ink or Highlight Ink. You can get the InkType using the IInkGraphic interface. The IInkGraphic interface exposes the stroke geometry as polyline geometry.

Using the IInkGraphicTool interface, you can control the properties of the Pen tool, such as width, tip type, and color of the ink that is drawn, or you can create your own Pen tool.

Geometry: InkGraphic accepts geometry of type esriGeometryPolyline. The Polyline is used as the geometry with which the symbol is drawn.

InkGraphic does not implement the following properties and will return E_NOTIMPL for them:

IElementProperties::AutoTransform
IElementProperties2::AutoTransform
IElementProperties3::AutoTransform
IElementProperties::CustomProperty
IElementProperties2::CustomProperty
IElementProperties3::CustomProperty

                throws IOException,
                       AutomationException

Indicates if the given x and y coordinates are contained by the element.

Remarks

HitTest returns a boolean value indicating whether or not the current element is intersected by the specified coordinate pair and tolerance distance. For instance, if we have a line element selected, the HitTest is determining whether that line element is within the specified tolerance from the given X and Y. A value of TRUE is returned if the element is within the tolerance, while FALSE is returned if it is not.

The X,Y, and tolerance values should be specified in map units.

isAutoTransform

public boolean isAutoTransform()
                        throws IOException,
                               AutomationException

Indicates if transform is applied to symbols and other parts of element. False = only apply transform to geometry.

Remarks

AutoTransform is a boolean values that indicates whether internal setings should be transformed along with the elements's geometry, when a transform is applied via ITransform2D. For instance, if I have a point element and I rotate it around a central location (the anchor point of the rotation being different from the point element iself), then the AutoTransform property is used to determine whether the orientation of the symbol associated to the element should also be rotated by the same amount.

                         throws IOException,
                                AutomationException

Custom property.

Remarks

CustomProperty is a place for developers to attach custom objects to an element. Previous versions of the software required that the specified variant be of type VT_UNKNOWN, i.e. a reference to an object, but that requirement has since been removed. Now, the CustomProperty can also be a simple type like an integer, double, boolean (VARIANT_BOOL) or a string (BSTR).

When this property is an object reference, the object must implement a persistence interface, so if you write a custom object it must implement IPersistStream or IPersistVariant. As an alternative to writing a custom object, you can use a PropertySet or XMLPropertySet, since they both already implement IPersistStream.

CustomProperty is never used by the core ArcObjects for its own elements, but the core software will expect to find an IPersistStream or IPersistVariant interface when the this property is an object reference, and it is part of an element being retrieved from or stored in an .mxd file.

Scales about the specified origin using seperate horizonal and vertical scales. The origin point can be in a different spatial reference than the geometry being scaled.

Description

Stretches the Geometry a factor of sX along the X-Axis and a factor of sY along the Y-Axis (where sX is the ratio of Old Width to New Width, and sY is the ratio of Old Height to New Height). The Origin point is the reference Point from which the transformation is performed (Regardless of the location of the Origin point, the Geometry resulting from the transformation is the same, except for a positional offset). The Origin is the only point in the transformation guaranted to remain in the same location after the transformation is complete.

Remarks

Note: Caution must be taken when scaling a CircularArc or a geometry containing CircularArc segments. Unless Abs(ScaleX) = Abs(ScaleY), the resulting CircularArcs will not retain the characteristics of the original geometry (since they remain CircularArcs).
