Methods
AddRect(RectangleF)
Appends a rectangle to the current path as a complete subpath.
public virtual void AddRect(RectangleF rect)Parameters
rect RectangleF
A rectangle to draw.
BeginDocument(Document)
Begins rendering of the document.
public virtual void BeginDocument(Document document)Parameters
document Document
The document.
BeginElement(Element, RectangleF)
Begins rendering of the node.
public virtual bool BeginElement(Element element, RectangleF rect)Parameters
element Element
The Aspose.Html.Dom.Element.
rect RectangleF
Bounding box of the node.
Returns
Returns [true] if element should be processed.
BeginPage(SizeF)
Begins rendering of the new page.
public virtual void BeginPage(SizeF size)Parameters
size SizeF
Size of the page.
Clip(FillRule)
Modifies the current clipping path by intersecting it with the current path, using the FillRule to determine the region to fill. This method terminates current path.
public virtual void Clip(FillRule rule)Parameters
rule FillRule
Filling rule specifies how the interior of a closed path is clipped
ClosePath()
Closes the current subpath by appending a straight line segment from the current point to the starting point of the subpath. If the current subpath is already closed, “ClosePath” does nothing. This operator terminates the current subpath. Appending another segment to the current path begins a new subpath, even if the new segment begins at the endpoint reached by the “ClosePath” method.
public virtual void ClosePath()CubicBezierTo(PointF, PointF, PointF)
Appends a cubic Bézier curve to the current path. The curve extends from the current point to the point pt2, using pt1 and pt2 as the Bézier control points. The new current point is pt3.
public virtual void CubicBezierTo(PointF pt1, PointF pt2, PointF pt3)Parameters
pt1 PointF
Coordinates of first point
pt2 PointF
Coordinates of second point
pt3 PointF
Coordinates of third point
Dispose()
Performs application-defined tasks associated with freeing, releasing, or resetting unmanaged resources.
public void Dispose()Dispose(bool)
Releases unmanaged and - optionally - managed resources.
protected virtual void Dispose(bool disposing)Parameters
disposing bool
true to release both managed and unmanaged resources; false to release only unmanaged resources.
DrawImage(byte[], WebImageFormat, RectangleF)
Draws the specified image.
public virtual void DrawImage(byte[] data, WebImageFormat imageFormat, RectangleF rect)Parameters
data byte[]
An array of bytes representing the image.
imageFormat WebImageFormat
Image format.
rect RectangleF
A rectangle which determines position and size to draw.
EndDocument()
Ends rendering of the document.
public virtual void EndDocument()EndElement(Element)
Ends rendering of the node.
public virtual void EndElement(Element element)Parameters
element Element
The Aspose.Html.Dom.Element.
EndPage()
Ends rendering of the current page.
public virtual void EndPage()Fill(FillRule)
Fills the entire region enclosed by the current path. If the path consists of several disconnected subpaths, it fills the insides of all subpaths, considered together. This method terminates current path.
public virtual void Fill(FillRule rule)Parameters
rule FillRule
Filling rule specifies how the interior of a closed path is filled
FillText(string, PointF)
Fills the specified text string at the specified location.
public virtual void FillText(string text, PointF pt)Parameters
text string
String to fill.
pt PointF
Point that specifies the coordinates of the text.
Flush()
Flushes all data to output stream.
public virtual void Flush()GetExtension()
Gets extension of the output file.
protected virtual string GetExtension()Returns
The file extension.
Initialize()
Initializes context stack.
protected virtual void Initialize()LineTo(PointF)
Appends a straight line segment from the current point to the point (pt). The new current point is pt.
public virtual void LineTo(PointF pt)Parameters
pt PointF
Point of where to create the line to.
MoveTo(PointF)
Begins a new subpath by moving the current point to coordinates of the parameter pt, omitting any connecting line segment. If the previous path construction method in the current path was also “MoveTo”, the new “MoveTo” overrides it; no vestige of the previous “MoveTo” operation remains in the path.
public virtual void MoveTo(PointF pt)Parameters
pt PointF
Point of where to move the path to.
RestoreGraphicContext()
Restores the entire graphics context to its former value by popping it from the stack.
public virtual void RestoreGraphicContext()SaveGraphicContext()
Pushes a copy of the entire graphics context onto the stack.
public virtual void SaveGraphicContext()Stroke()
Strokes a line along the current path. The stroked line follows each straight or curved segment in the path, centered on the segment with sides parallel to it. Each of the path’s subpaths is treated separately. This method terminates current path.
public virtual void Stroke()StrokeAndFill(FillRule)
Strokes and fill current path. This method terminates current path.
public virtual void StrokeAndFill(FillRule rule)Parameters
rule FillRule
Filling rule specifies how the interior of a closed path is filled.
StrokeText(string, PointF)
Strokes the specified text string at the specified location.
public virtual void StrokeText(string text, PointF pt)Parameters
text string
String to stroke.
pt PointF
Point that specifies the coordinates where to start the text. </tgraphiccontext,></tgraphiccontext,></tgraphiccontext,></tgraphiccontext,>
