CustomLineCap Functions

Windows GDI+ exposes a flat API that consists of about 600 functions, which are implemented in Gdiplus.dll and declared in Gdiplusflat.h. The functions in the GDI+ flat API are wrapped by a collection of about 40 C++ classes. It is recommended that you do not directly call the functions in the flat API. Whenever you make calls to GDI+, you should do so by calling the methods and functions provided by the C++ wrappers. Microsoft Product Support Services will not provide support for code that calls the flat API directly. For more information on using these wrapper methods, see GDI+ Flat API.

The following flat API functions are wrapped by the CustomLineCap C++ class.

Flat functionWrapper methodDescription
GpStatus WINGDIPAPI GdipCreateCustomLineCap(GpPath* fillPath, GpPath* strokePath, GpLineCap baseCap, REAL baseInset, GpCustomLineCap **customCap) CustomLineCap::CustomLineCap Creates a CustomLineCap::CustomLineCap object.
GpStatus WINGDIPAPI GdipDeleteCustomLineCap(GpCustomLineCap* customCap)virtual ~CustomLineCap()Cleans up resources used by a CustomLineCap::CustomLineCap object.
GpStatus WINGDIPAPI GdipCloneCustomLineCap(GpCustomLineCap* customCap, GpCustomLineCap** clonedCap) CustomLineCap::Clone The CustomLineCap::Clone method copies the contents of the existing object into a new CustomLineCap object.
GpStatus WINGDIPAPI GdipGetCustomLineCapType(GpCustomLineCap* customCap, CustomLineCapType* capType)Not called by wrapper methods.

When this function is called, the capType parameter receives the type of the CustomLineCap specified by customCap.

The CustomLineCapType enumeration (defined in GdiplusEnums.h) has two elements: CustomLineCapTypeDefault = 0 and CustomLineCapTypeAdjustableArrow = 1.

GpStatus WINGDIPAPI GdipSetCustomLineCapStrokeCaps(GpCustomLineCap* customCap, GpLineCap startCap, GpLineCap endCap) CustomLineCap::SetStrokeCap The CustomLineCap::SetStrokeCap method sets the LineCap object used to start and end lines within the GraphicsPath object that defines this CustomLineCap object.

GpStatus WINGDIPAPI GdipGetCustomLineCapStrokeCaps(GpCustomLineCap* customCap, GpLineCap* startCap, GpLineCap* endCap)

CustomLineCap::GetStrokeCaps The CustomLineCap::GetStrokeCaps method gets the end cap styles for both the start line cap and the end line cap. Line caps are LineCap objects that end the individual lines within a path.
GpStatus WINGDIPAPI GdipSetCustomLineCapStrokeJoin(GpCustomLineCap* customCap, GpLineJoin lineJoin) CustomLineCap::SetStrokeJoin The CustomLineCap::SetStrokeJoin method sets the style of line join for the stroke. The line join specifies how two lines that intersect within the GraphicsPath object that makes up the custom line cap are joined.
GpStatus WINGDIPAPI GdipGetCustomLineCapStrokeJoin(GpCustomLineCap* customCap, GpLineJoin* lineJoin) CustomLineCap::GetStrokeJoin The CustomLineCap::GetStrokeJoin method returns the style of LineJoin used to join multiple lines in the same GraphicsPath object.
GpStatus WINGDIPAPI GdipSetCustomLineCapBaseCap(GpCustomLineCap* customCap, GpLineCap baseCap) CustomLineCap::SetBaseCap The CustomLineCap::SetBaseCap method sets the LineCap that appears as part of this CustomLineCap at the end of a line.
GpStatus WINGDIPAPI GdipGetCustomLineCapBaseCap(GpCustomLineCap* customCap, GpLineCap* baseCap) CustomLineCap::GetBaseCap The CustomLineCap::GetBaseCap method gets the style of the base cap. The base cap is a LineCap object used as a cap at the end of a line along with this CustomLineCap object.

GpStatus WINGDIPAPI GdipSetCustomLineCapBaseInset(GpCustomLineCap* customCap, REAL inset)

CustomLineCap::SetBaseInset The CustomLineCap::SetBaseInset method sets the base inset value of this custom line cap. This is the distance between the end of a line and the base cap.
GpStatus WINGDIPAPI GdipGetCustomLineCapBaseInset(GpCustomLineCap* customCap, REAL* inset) CustomLineCap::GetBaseInset The CustomLineCap::GetBaseInset method gets the distance between the base cap to the start of the line.
GpStatus WINGDIPAPI GdipSetCustomLineCapWidthScale(GpCustomLineCap* customCap, REAL widthScale) CustomLineCap::SetWidthScale The CustomLineCap::SetWidthScale method sets the value of the scale width. This is the amount to scale the custom line cap relative to the width of the Pen used to draw lines. The default value of 1.0 does not scale the line cap.
GpStatus WINGDIPAPI GdipGetCustomLineCapWidthScale(GpCustomLineCap* customCap, REAL* widthScale) CustomLineCap::GetWidthScale The CustomLineCap::GetWidthScale method gets the value of the scale width. This is the amount to scale the custom line cap relative to the width of the Pen object used to draw a line. The default value of 1.0 does not scale the line cap.
