Meanwhile, cairo_ft_font_create now accepts an FT_Library parameter. * src/cairo_ft_font.c: Add ft_library field so that fonts that own their own FT_Library can also clean it up. Eliminate static FT_Library and _init_cairo_ft_lib. (cairo_ft_font_create): Now accepts an FT_Library argument. (_cairo_ft_font_create): Create an FT_Library owned by this font, (this only happens as part of the "toy API") (_cairo_ft_font_destroy): Clean up ft_font->ft_library if necessary.

(_cairo_gstate_current_font): gstate->font must never be NULL. (_cairo_gstate_current_font_extents): Can never be called with a NULL gstate. * src/cairo_font.c (_cairo_font_create): Rename _cairo_font_create_font and move to top of file.

Replace XFoo with cairo_foo for double and fixed * src/cairoint.h: add cairo_fixed_to_double and cairo_double_to_fixed Carl says he's got similar code, so he'll have to fix things if I get this committed quickly enough. 2003-09-04 Carl Worth * util/cairo-api-update: Added script to update source code using Cairo to the latest API. * configure.in (CAIRO_VERSION): Bumped version to 0.1.1 * src/cairoint.h (DEPRECATE): Added magic DEPRECATE macro which provides an asm-based alias for old function names. This works on ELF systems with gcc version >= 2. * src/cairo.h (cairo_get_status_string): Deprecated all cairo_get_* names in favor of cairo_current_*. The deprecated function names will trigger either a warning or a link error, but in both cases with a useful message giving both the old and new name of the function. Three of the function name changes are different than the single word substituion: cairo_get_current_color -> cairo_current_color cairo_get_status -> cairo_status cairo_get_status_string -> cairo_status_string 2003-09-03 Carl Worth * src/cairo.h: Change cairo_get_matrix interface to accept a cairo_matrix_t* rather than 6 double*. * src/cairo.c (cairo_get_matrix): Add implementation of cairo_get_matrix. 2003-08-29 Carl Worth * src/cairo_surface.c (_cairo_surface_composite): Optimized case where src is in memory, dst is on server, and mask is NULL.

Instead, sort vertices by fixed point slope comparisons. (_cairo_pen_add_points): Fixed to remove duplicate pen vertices appearing at beginning and end of vertex array. (_pen_vertex_compare): New fixed-point "angle" comparison for pen vertices. A bit trickier than before, but much more accurate. * src/cairo_path_stroke.c (_cairo_stroker_face_clockwise): Share clockwise calculation with other modules. * src/cairo_path_bounds.c: * src/cairo_path_fill.c: * src/cairo_path_stroke.c: * src/cairo_pen.c: * src/cairo_polygon.c: * src/cairo_spline.c: * src/cairo_traps.c: * src/cairo_path.c: Replaced all references to XFixed, XPointFixed, XLineFixed, and XTrapezoid with new cairo_fixed_t, cairo_point_t, cairo_line_t, and cairo_trapezoid_t. * src/cairo_path.c: (_cairo_path_interpret): Made the path interpreter callback names consistent, (eg. add_edge rather than AddEdge). * src/cairo_gstate.c (_cairo_gstate_text_extents): Now silently exits for a non X surface, (avoids a crash until we can implement the libic text backend). * src/cairo_gstate.c (_cairo_gstate_end_group): (_cairo_gstate_clip_and_composite_trapezoids): (_cairo_gstate_show_surface): Replaced all XcCalls with corresponding cairo_surface_calls. * src/cairo_gstate.c (_cairo_gstate_transform_point): (_cairo_gstate_transform_font): (_cairo_gstate_text_extents): Renamed from the garbled names (eg. cairo_gstateransform_point) leftover from the great renaming. * src/cairo_color.c (_cairo_color_set_rgb): Reworked cairo_color_t to eliminate reference to an XcColor object. * src/cairo.h: Dropped include of , added , , and * src/cairo.c (cairo_get_fill_rule): Added missing cairo_get_fill_rule. * configure.in (PKG_CHECK_MODULES): Drops xc, add libic * cairo.pc.in (Requires): Drop xc, add libic. 2003-07-25 Carl Worth * src/cairo_traps.c (_line_segs_intersect_ceil): We don't need a loop here, (just a conditional increment). This time, we've actually done the error analysis to back this up. 2003-07-24 Carl Worth * src/cairo_traps.c (cairo_traps_tessellate_polygon): Massive cleanup of polygon tessellation, (it might actually be correct now). 2003-07-23 Carl Worth * src/cairoint.h: Introduced some cairo_fixed_*_t types.

(There are still some reamining problems though). (cairo_traps_tessellate_polygon): Better fix for the same bug. Should cover all cases, (and it's moe efficient too). 2003-07-18 Carl Worth * src/cairo.h: Fixed some inconsistent tag/typedef names that were missed in the great renaming. 2003-07-18 Carl Worth * 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 * src/xrmatrix.c (XrMatrixGetAffine): Added XrMatrixGetAffine (from Soorya Kuloor) * src/xr.c (XrGetAlpha): Added XrGetAlpha (XrGetRGBColor): Added XrGetRGBColor 2003-06-12 Carl Worth * src/xrgstate.c (_XrGStateScale): Scale by 0 now causes an InvalidMatrix error. 2003-05-28 Carl Worth * 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 * 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 * 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 * 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 * 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 * src/xrsurface.c (XrSurfaceDestroy): Fix memory leak of surface->image_data. 2003-04-25 Carl Worth * configure.in: Fixed libtool versioning 2003-04-17 Carl Worth * 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 * xrgstate.c (_XrGStateShowImageTransform): Fixed transformed images which were sometimes 1 pixel too tall/wide. 2003-02-06 Carl Worth * 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 * 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 * 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 * 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 * 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 * 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 * 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 * xrsurface.c (_XrSurfaceSetImage): Fixed leak of the image pixmap. 2002-11-01 Carl Worth * 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 * 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 * xrgstate.c (_XrGStateSelectFont, _XrGStateScaleFont) (_XrGStateTransformFont, _XrGStateShowText): Added basic font support. * xr.c (XrSelectFont, XrScaleFont, XrTransformFont): Added basic font support. 2002-10-28 Carl Worth * 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 * 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 * xr.c (XrSetFillRule): Added support to set fill rule. 2002-10-23 Carl Worth * xrtraps.c (_XrTrapsTessellatePolygon): Fix for polygon with multiple sub-polygons that are disjoint in Y. 2002-07-16 Carl Worth * 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 ;-)
