Member name	Value	Description
mcgsVisible	1	Object is visible.
mcgsDrawHandles	2	Handles are displayed when object is selected.
mcgsInvertHandles	4
mcgsCustomMask	24	Mask for 2 bits allowing for3 possible custom type-specific object attributes. Currently the only one is the mcgsCustomBitmapNoInterpolate McGraphObjBitmap custom attribute.
mcgsCustomBitmapNoInterpolate	8	A mcgsCustomMask attribute thatcan be set for McGraphObjBitmap objects which causes their scaling to use nearest neighbor replication rather than the default bi-linear interpolation. The effect of this is to cause bitmap scaling to match the way that images are scaled with "chunky" pixel edges instead of smoothed edges on zoomed-in images. To set use: myMcGraphObjBitmap.Style(mcgsCustomMask) = mcgsCustomBitmapNoInterpolate
mcgsAllowZoomWithImage	32	Object's McGraphObj.ZoomWithImage property can be set by the user.
mcgsAllowGrouping	64	Object can be grouped.
mcgsAllowRotate	128	Object can be rotated.
mcgsAllowSelect	256	Object can be selected by the user.
mcgsAllowMove	512	Object can be moved.
mcgsAllowResize	1024
mcgsAllowPropChange	2048	Object properties areedited with the obsolete internal properties dialog. As of 2013-07-29 this bit is not clear by default.
mcgsAllowNotify	4096	Notify McGraphOverlay clients when object changes.
mcgsAllowDelete	8192
mcgsShowSelectAlways	16384	Selected object handles willshow even if the overlay is not the being shown on the ActiveWindow (the McView with the focus) and even if the mcgsAllowSelect bit is clear (in this case, the object is still not selectable by the user). However, selected object handles will only be shown if the active tool is running on the object's parent McGraphOverlay and if the object's McGraphObj.Style mcgsDrawHandles bit is set.
mcgsBeingDestroyed	524288	Set during the EditClear, ObjectAboutToBeDeleted andObjectAboutToBeDestroyed notifies. Cannot be set by the user.
mcgsLabelTopleft	1048576	Object has a top left label attached.
mcgsLabelTopright	2097152	Object has a top right label attached.
mcgsLabelBtmleft	4194304	Object has a bottom left label attached.
mcgsLabelBtmright	8388608	Object has a bottom right label attached.
mcgsLabelCenter	16777216
mcgsLabelLinebgn	33554432	Display the label near the start of the object.For McGraphObjRect, this is the upper-left. For McGraphObjCircle, this is the left side of the circle.
mcgsLabelLineend	67108864	Display the label near the last point of the object.For McGraphObjRect, this is the lower-right. For McGraphObjCircle, this is the right side of the circle.
mcgsLabelInside	134217728	The label is positioned inside the specifiedposition. For mcgsLabelCenter, mcgsLabelLinebgn and mcgsLabelLineend the position is switched to the opposite side of the specified position.
mcgsLabelHidden	268435456
mcgsLabelRotates	536870912	The LabelObject'sAngleOfRotation property follows assignments to it's master object's AngleOfRotation property. Assignments to the LabelObject.AngleOfRotation can still be made.
mcgsLabelOnTopOfLayer	1073741824	When set, this bit forces theobject's label to be displayed at the top of the layer in which their master object is displayed. Such labels will be displayed after all other objects in the layer (including labels without this bit set) in the order in which their master object is displayed. If enabled, label collision prevention (see mcGraphOverlayOptionFlags.mcgoofMaskLabelCrowdingPrevention) continues to work for these "topmost" labels.
mcgsNoBits	0	No style bits
mcgsLabelPositionBitsMask	1877999616	Label position bits mask
mcgsLabelBitsMask	2146435072	Label position and hidden bits mask
mcgsAllBitsMask	-1	All style bits bits mask
