|
|
|
* xrtransform.c (_XrTransformDistance):
|
|
(_XrTransformPoint): changed to use individual X/Y arguments
|
|
rather tha an XPointDouble. This improves readability since
|
|
_XrTransformDistance is now always called with arguments of dx/dy
|
|
rather than pt.x/pt.y.
|
|
|
|
* xrpath.c (_XrPathMoveTo):
|
|
(_XrPathLineTo):
|
|
(_XrPathCurveTo):
|
|
(_XrPathClosePath): replaced public _XrPathAdd with explicit named
|
|
functions. This cleans up the implementation since _XrPathAdd,
|
|
which is unsafe with respect to argument consistency, is now
|
|
private. Also, since the _XrGState now maintains the current
|
|
point, I dropped all relative path operators from the XrPath data
|
|
structures.
|
|
|
|
* xrgstate.c (_XrGStateMoveTo):
|
|
(_XrGStateLineTo):
|
|
(_XrGStateCurveTo):
|
|
(_XrGStateRelMoveTo):
|
|
(_XrGStateRelLineTo):
|
|
(_XrGStateRelCurveTo): Replaces _XrGStateAddPathOp and
|
|
_XrGStateAddUnaryPathOp with explicit named functions for each
|
|
operator type. This change introduces the current point state into
|
|
the XrGState structure rather than postponing its calculation
|
|
until path interpretation.
|
|
|
|
* xrgstate.c (_XrGStateSetDrawable):
|
|
(_XrGStateSetVisual):
|
|
(_XrGStateSetFormat):
|
|
(_XrGStateSetOperator):
|
|
(_XrGStateSetRGBColor):
|
|
(_XrGStateSetTolerance):
|
|
(_XrGStateSetAlpha):
|
|
(_XrGStateSetFillRule):
|
|
(_XrGStateSetLineWidth):
|
|
(_XrGStateSetLineCap):
|
|
(_XrGStateSetLineJoin):
|
|
(_XrGStateSetMiterLimit):
|
|
(_XrGStateTranslate):
|
|
(_XrGStateScale):
|
|
(_XrGStateRotate):
|
|
(_XrGStateConcatMatrix):
|
|
(_XrGStateNewPath): : Added XrStatus return values to many
|
|
functions -- just for consistency, these functions can not return
|
|
errors in any case.
|
|
|
|
* xr.c (XrShowText): Started to ass XrShowText, (still not functional)
|
|
|
|
2002-10-24 Carl Worth <cworth@isi.edu>
|
|
|
|
* xr.c (XrSetFillRule): Added support to set fill rule.
|
|
|
|
2002-10-23 Carl Worth <cworth@isi.edu>
|
|
|
|
* xrtraps.c (_XrTrapsTessellatePolygon): Fix for polygon with
|
|
multiple sub-polygons that are disjoint in Y.
|
|
|
|
2002-07-16 Carl Worth <cworth@isi.edu>
|
|
|
|
* Xr.h: Renamed xrpicture.c to xrsurface.c as part of the move.
|
|
Added XrSetFormat, XrSetOperator, XrSetLineCap, XrSetLineJoin, and
|
|
XrSetMiterLimit, (although the line style drawing code is not all
|
|
in place yet).
|
|
|
|
* xrpath.c (XrPathLineTo): Changed LineTo semantics to be the same
|
|
as MoveTo if there was no previous MoveTo.
|
|
|
|
* xrtraps.c: Added tessellation code, (lifted from
|
|
XRenderCompositeDoublePoly which can now disappear).
|
|
|
|
* xrgstate.c: Changed stroke code to incrementally build a list of
|
|
trapezoids rather than forming one giant polygonal outline and
|
|
rendering that. This should be more efficient.
|
|
(_XrGStateFillPath): Now uses Xr's own tessellation along with
|
|
XcCompositeTrapezoids.
|
|
|
|
* Xr.h: Moved all of Xr away from Xrender to the new Xc library.
|
|
|
|
* xrsurface.c: Renamed from xrpicture.c, (part of the move from
|
|
XRender to Xc).
|
|
|
|
* Started keeping a ChangeLog ;-)
