| CT_EXPORT TResult COutline::AppendCircularPenEnvelope | ( | CEngine * | aEngine, |
| const MPath & | aPath, | ||
| const TCircularPen & | aPen, | ||
| const TRect * | aClip, | ||
| bool | aPathIn64ths | ||
| ) |
Append contours that are the envelope of the strokes in aPath, drawn using a circular pen according to the parameters supplied in aParam.
If aEngine is non-null it may be used to obtain temporary storage to speed up the work.
| CT_EXPORT TResult COutline::AppendCircularPenEnvelopeSides | ( | CEngine * | aEngine, |
| const TContour & | aContour, | ||
| TFixed | aPenWidth, | ||
| const TRect * | aClip, | ||
| bool | aPathIn64ths | ||
| ) |
Append the left and right sides of the envelope of aContour, with no end caps, drawn using a circular pen along aContour. aPathIn64ths indicates whether the contour's coordinates are in 64ths of pixels or full pixels.
If aEngine is non-null it may be used to obtain temporary storage to speed up the work.
Append a contour, taking ownership of it.
Append a new empty contour to the outline and return it.

| ) | [static] |
Create an outline that is the envelope of a set of strokes drawn using a circular pen, according to the parameters supplied in aParam. The strokes are the contours of aPath. aPathIn64ths indicates whether the path coordinates are in 64ths of pixels or full pixels.
If aEngine is non-null it may be used to obtain temporary storage to speed up the work.
| void CartoType::COutline::Clear | ( | ) | [inline] |
Clear an outline, freeing all memory used.
| void CartoType::COutline::ClearContents | ( | ) | [inline] |
Clear the contents of the outline, preserving the allocated memory.
| const CContour& CartoType::COutline::Contour | ( | int32 | aIndex | ) | const [inline] |
Return a constant reference to a contour, selected by its index.
| CContour& CartoType::COutline::Contour | ( | int32 | aIndex | ) | [inline] |
Return a non-constant reference to a contour, selected by its index.
| int32 CartoType::COutline::Contours | ( | ) | const [inline, virtual] |
Return the number of contours.
Implements CartoType::MPath.
| void CartoType::COutline::GetContour | ( | int32 | aIndex, |
| TContour & | aContour | ||
| ) | const [inline, virtual] |
Return the contour indexed by aIndex.
Implements CartoType::MPath.
| CT_EXPORT COutline * COutline::Markers | ( | TResult & | aError, |
| const MPath & | aPath, | ||
| const CMarker *const | aMarkerStart, | ||
| const CMarker *const | aMarkerMid, | ||
| const CMarker *const | aMarkerEnd, | ||
| const TRect & | aClip | ||
| ) | [static] |
Create an outline that contains markers along the path
| CT_EXPORT int32 COutline::MemoryUsed | ( | ) | const |
Return the number of bytes of heap memory used by the outline.
| CT_EXPORT COutline * COutline::Triangulate | ( | TResult & | aError, |
| const MPath & | aPath, | ||
| double | aTolerance | ||
| ) | [static] |
Create an outline consisting only of triangles, representing the original path. aTolerance is used if the path contains curves. It is the maximum distance of any control point from the straight line used to approximate a curve. Curves are split until this tolerance is achieved.
