Should cover all cases, (and it's moe efficient too). - -2003-07-18 Carl Worth <cworth@east.isi.edu> - - * src/cairo.h: Fixed some inconsistent tag/typedef names that were - missed in the great renaming. - -2003-07-18 Carl Worth <cworth@isi.edu> - - * src/cairo.h: Renamed everything from Xr* to cairo_*. - - * util/xr2cairo: Added utility script xr2cairo to help users fix - their source code. - -2003-07-03 Carl Worth <cworth@isi.edu> - - * src/xrmatrix.c (XrMatrixGetAffine): Added XrMatrixGetAffine - (from Soorya Kuloor) - - * src/xr.c (XrGetAlpha): Added XrGetAlpha - (XrGetRGBColor): Added XrGetRGBColor - -2003-06-12 Carl Worth <cworth@isi.edu> - - * src/xrgstate.c (_XrGStateScale): Scale by 0 now causes an - InvalidMatrix error. - -2003-05-28 Carl Worth <cworth@isi.edu> - - * src/xrmatrix.c (XrMatrixMultiply): Eliminated - _XrMatrixMultiplyIntoRight and _XrMatrixMultiplyIntoLeft. - - * src/xrgstate.c (_XrGStateClipAndCompositeTrapezoids): Fixed - missing translation of clip surface. - - * src/Xr.h: Added XrSurfacePutImage - -2003-05-16 Carl Worth <cworth@isi.edu> - - * src/xrint.h: Added ppm filed (pixels per meter) to both - XrSurface and XrGState. - - * src/xrgstate.c (_XrGStateSetTargetSurface): Fixup CTM according - to change in surface->ppm. - (_XrGStateDefaultMatrix): Default matrix is no longer an identity - matrix, but rather a matrix that provides some relates user space - units to real-world dimensions in a meaningful way, (default 3780 - user space units per meter). This conversion is not exact, but is - rather as close as possible while also guaranteeing that one user - space unit maps to an integer number of device pixels. - -2003-05-15 Carl Worth <cworth@isi.edu> - - * src/xr.c (XrSetTargetDrawable): Moved implementation up from - _XrGStateSetTargetDrawable, (eg. all convenience functions should - be taken care of at the xr.c level ratehr than xrgstate.c) - - * src/Xr.h: Added convenience function XrSetTargetImage - -2003-05-14 Carl Worth <cworth@isi.edu> - - * src/xrfont.c (_XrFontResolveXftFont): Fixed fonts to pull - pixelsize out of the transformation matrix. Fonts are now properly - hinted regardless of scaling. - - * src/Xr.h: Three new functions for manipulating surfaces: - XrSurfaceSetMatrix, XrSurfaceGetMatrix, XrSurfaceSetFilter. - - * src/Xr.h: Removed broken XrShowImage* functions. Changed - XrShowSurface to not require X/Y but instead depend on the CTM for - translation, (or the surface transformation matrix). I'd like to - get rid of width/height as well but it turns out an XrSurface is - not aware of its dimensions. - - * src/Xr.h: Added convenience function for building rectangular - paths: XrRectangle. - - * src/Xr.h: Added functions for performing transformations with - the CTM and its inverse: XrTransformPoint, XrTransformDistance, - XrInverseTransformPoint, XrInverseTransformDistance. - - * src/Xr.h: XrConcatMatrix and XrSetMatrix now accept a pointer to - an XrMatrix rather than 6 doubles. - - * src/Xr.h: Now exporting opaque XrMatrix object with several - functions: XrMatrixCreate, XrMatrixDestroy, XrMatrixCopy, - XrMatrixSetIdentity, XrMatrixSetAffine, XrMatrixTranslate, - XrMatrixScale, XrMatrixRotate, XrMatrixInvert, XrMatrixMultiply, - XrMatrixTransformDistance, XrMatrixTransformPoint. - -2003-05-12 Carl Worth <cworth@isi.edu> - - * src/Xr.h: Added XrSetPattern.

Currently used internally, (for computing the size of the - clip surface), and not exported publically. - - * src/xrgstate.c (_XrGStateStroke): Implemented clip support for - strokes. - (_XrGStateClip): New _XrGStateClip function fills the current path - onto the gstate->clip surface. - - * src/xr.c (XrClip): Added preliminary/experimental clip - functionality. The current implementation only clips stroked - elements, (not fills, images, or text). It's alway quite - inefficeient. - - * src/xr.c (XrGetOperator): - (XrGetTolerance): - (XrGetLineWidth): - (XrGetLineCap): - (XrGetLineJoin): - (XrGetMiterLimit): - (XrGetCurrentPoint): Added several new query functions. - -2003-04-26 Carl Worth <cworth@isi.edu> - - * src/xrsurface.c (XrSurfaceDestroy): Fix memory leak of - surface->image_data. - -2003-04-25 Carl Worth <cworth@east.isi.edu> - - * configure.in: Fixed libtool versioning - -2003-04-17 Carl Worth <cworth@isi.edu> - - * Switched from imake to autotools. - - * src/xrint.h: XrSurface structure is now greatly simplified, - (details now handled by XcSurface). - - * src/Xr.h: Eliminated Display * parameter so Xr can be used for - non-X drawing. - Removed XrPushGroup/XrPopGroup. - Replaced XrSetDrawable/XrSetVisual with XrSetTargetDrawable. - Added XrSetTargetSurface and several new XrSurfaceCreate - functions. - Added XrShowSurface, (functionality overlaps with XrShowImage -- - need to fix this) - - -2003-02-14 Carl Worth <cworth@east.isi.edu> - - * xrgstate.c (_XrGStateShowImageTransform): Fixed transformed - images which were sometimes 1 pixel too tall/wide. - -2003-02-06 Carl Worth <cworth@isi.edu> - - * xrpen.c (_XrPenVerticesNeeded): Fixed to use determinant rather - than eigenvalues to compute maximal scaling of radius. Now avoids - embarrassing segfaults due to NaN from the eigenvalue computation. - -2003-01-28 Carl Worth <cworth@isi.edu> - - * xrtraps.c (_XrTrapsTessellateTriangle): Fixed to not re-order - the array provided as an argument. (Note: the rectangle and - polyghon tessellators still perform reordering). - - * xrstroker.c (_XrStrokerJoin): - (_XrStrokerCap): Implemented round caps and joins. - (_XrStrokerDoneSubPath): Fixed initial cap, (was always being - drawn on the inside previously). - - * xrpen.c (_XrPenInit): Fixed to keep pen vertex theta values all - in device space. - (_XrPenAddPoints): Removed the silly flags from the pen vertices, - (in favor of just using the FindActiveVertex functions) - (_XrPenFindActiveCWVertexIndex): - (_XrPenFindActiveCCWVertexIndex): Added functions needed for round - caps/joins. - - * xrgstate.c (_XrGStateSetDash): Fixed to accept a NULL dash array - to revert to no dashing. - -2003-01-28 Carl Worth <cworth@east.isi.edu> - - * xrtraps.c (_XrTrapsTessellateTriangle): Restored triangle - tessellation functionality, (I think it's correct this time). - - * xrstroker.c (_XrStrokerJoin): Bevel joins now use triangle - tessellation rather than polygon tessellation. - -2003-01-24 Carl Worth <cworth@east.isi.edu> - - * xrpolygon.c (_XrPolygonAddEdge): Fixed to handle multiple - sub-polygons. - - * xrstroker.c (_XrStrokerJoin): Fixed handling of miter limit. - - * local.def: Added local.def for building outside the xc tree. - -2002-12-03 Carl Worth <cworth@isi.edu> - - * xrstroker.c (_XrStrokerJoin): - (_XrStrokerCap): Fixed to track change in winding rule parameter - to XrTrapsTessellatePolygon, (otherwise self-intersecting splines - suddenly had holes). - - * xrpen.c (_XrPenStrokeSpline): Fixed to track change in winding - rule parameter to XrTrapsTessellatePolygon. - -2002-11-11 Carl Worth <cworth@isi.edu> - - * xrtransform.c (_XrTransformBoundingBox): Added support for - transforming a bounding box, (an axis-aligned rectangle prior to - transformation). The ShowImage support needs this. - (_XrTransformComputeInverse): Now catches error case for - non-invertible matrix. - - * xrsurface.c (_XrSurfaceSetTransform): Fixed ordering of matrix - for call to RenderSetPictureTransform - - * xrgstate.c (_XrGStateSetMatrix): - (_XrGStateIdentityMatrix): Support for new Xr matrix functions. - (_XrGStateShowImage): - (_XrGStateShowImageTransform): Fixed transformation of images. - - * xr.c (XrSetMatrix): - (XrDefaultMatrix): - (XrIdentityMatrix): Added 3 matrix manipulation functions. - -2002-11-04 Carl Worth <cworth@isi.edu> - - * xrsurface.c (_XrSurfaceDereference): - (_XrSurfaceDereferenceDestroy): Fixed bug in reference counting - logic. - (_XrSurfaceSetDrawableWH): XrSurface now keeps track of its width/height. - (_XrSurfaceGetDrawable): - (_XrSurfaceGetWidth): - (_XrSurfaceGetHeight): - (_XrSurfaceGetDepth): New accessor functions. - - * xrgstate.c (_XrGStateBeginGroup): - (_XrGStateEndGroup): Preliminary group support. Not too efficient - since it always composite's a full-size picture from child group - to parent picture, (even if only a small portion has - non-transparent pixels). - (_XrGStateShowImageTransform): Fixed show image to use current - alpha value. - - * xrfont.c (_XrFontResolveXftFont): Fixed memory leak - (FcPatternDestroy). There's still some meory - leaking/left-reachable in Xft/fontconfig that I need to track - down. - - * xr.c (XrPushGroup): - (XrPopGroup): Added preliminary group support. I think I like - having this in the API as it takes several burdens away from the - user, (plus it matches the PDF model). Things to do still: think - about the names of these functions. Re-read the PDF semantics to - see if we're missing anything. - -2002-11-02 Carl Worth <cworth@isi.edu> - - * xrsurface.c (_XrSurfaceSetImage): Fixed leak of the image - pixmap. - -2002-11-01 Carl Worth <cworth@east.isi.edu> - - * xrsurface.c (_XrSurfaceSetImage): Prelimary image - support. Really only works with ARGB32. I still need to think - about what formats will be supported. - (_XrSurfaceSetTransform): Partial support for transformed - surfaces. - (_XrSurfaceGetXcSurface): Moved all creation/destruction of the - XcSurface into this function so that it is only lazily created - when needed. - - * xrgstate.c (_XrGStateSetCurrentPt): gstate now can throw errors - when an operation needs current point, but it doesn't exist yet. - (_XrGStateShowImage, _XrGStateShowImageTransform): Preliminary - image support, (currently it only scales according to the CTM. The - matrix passed with the image doesn't do anything yet.) - - * xrfont.c (_XrFontInitCopy): Removed bogus out of memory errors. - - * xr.c (XrShowImage, XrShowImageTransform): Added very preliminary - image support. Things don't work completely yet and all the - interfaces are likely to change. - (XrGetStatusString): Added function to map status values to strings. - -2002-10-31 Carl Worth <cworth@isi.edu> - - * xrfont.c (_XrFontInit): - (_XrFontInitCopy): - (_XrFontDeinit): - (_XrFontSelect): - (_XrFontResolveXftFont): Updated by ripping all font support from - Xc and just putting a couple of calls to Xft and fontconfig right - here in xrfont. - - * xr.c (XrTextExtents): Added XrTextExtents. - -2002-10-29 Carl Worth <cworth@east.isi.edu> - - * xrgstate.c (_XrGStateSelectFont, _XrGStateScaleFont) - (_XrGStateTransformFont, _XrGStateShowText): Added basic font - support. - - * xr.c (XrSelectFont, XrScaleFont, XrTransformFont): Added basic - font support. - -2002-10-28 Carl Worth <cworth@east.isi.edu> - - * xrstate.c (_XrStatePop): Added error case for XrRestore without - matching XrSave. - - * xrsurface.c (_XrSurfaceInit, _XrSurfaceReference) - (_XrSurfaceDereference): Added reference counting to XrSurface to - patch a memory leak. - -2002-10-26 Carl Worth <cworth@isi.edu> - - * 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 ;-) |
