The following +more-detailed instructions are generic; see the `README' file for +instructions specific to this package. + + The `configure' shell script attempts to guess correct values for +various system-dependent variables used during compilation. It uses +those values to create a `Makefile' in each directory of the package. +It may also create one or more `.h' files containing system-dependent +definitions. Finally, it creates a shell script `config.status' that +you can run in the future to recreate the current configuration, and a +file `config.log' containing compiler output (useful mainly for +debugging `configure'). + + It can also use an optional file (typically called `config.cache' +and enabled with `--cache-file=config.cache' or simply `-C') that saves +the results of its tests to speed up reconfiguring. Caching is +disabled by default to prevent problems with accidental use of stale +cache files. + + If you need to do unusual things to compile the package, please try +to figure out how `configure' could check whether to do them, and mail +diffs or instructions to the address given in the `README' so they can +be considered for the next release. If you are using the cache, and at +some point `config.cache' contains results you don't want to keep, you +may remove or edit it. + + The file `configure.ac' (or `configure.in') is used to create +`configure' by a program called `autoconf'. You need `configure.ac' if +you want to change it or regenerate `configure' using a newer version +of `autoconf'. + +The simplest way to compile this package is: + + 1. `cd' to the directory containing the package's source code and type + `./configure' to configure the package for your system. + + Running `configure' might take a while. While running, it prints + some messages telling which features it is checking for. + + 2. Type `make' to compile the package. + + 3. Optionally, type `make check' to run any self-tests that come with + the package. + + 4. Type `make install' to install the programs and any data files and + documentation. + + 5. You can remove the program binaries and object files from the + source code directory by typing `make clean'. To also remove the + files that `configure' created (so you can compile the package for + a different kind of computer), type `make distclean'. There is + also a `make maintainer-clean' target, but that is intended mainly + for the package's developers. If you use it, you may have to get + all sorts of other programs in order to regenerate files that came + with the distribution. + + 6. Often, you can also type `make uninstall' to remove the installed + files again. + +Compilers and Options +===================== + + Some systems require unusual options for compilation or linking that +the `configure' script does not know about. Run `./configure --help' +for details on some of the pertinent environment variables. + + You can give `configure' initial values for configuration parameters +by setting variables in the command line or in the environment. Here +is an example: + + ./configure CC=c99 CFLAGS=-g LIBS=-lposix + + *Note Defining Variables::, for more details. + +Compiling For Multiple Architectures +==================================== + + You can compile the package for more than one kind of computer at the +same time, by placing the object files for each architecture in their +own directory. To do this, you can use GNU `make'. `cd' to the +directory where you want the object files and executables to go and run +the `configure' script. `configure' automatically checks for the +source code in the directory that `configure' is in and in `..'. + + With a non-GNU `make', it is safer to compile the package for one +architecture at a time in the source code directory. After you have +installed the package for one architecture, use `make distclean' before +reconfiguring for another architecture. + + On MacOS X 10.5 and later systems, you can create libraries and +executables that work on multiple system types--known as "fat" or +"universal" binaries--by specifying multiple `-arch' options to the +compiler but only a single `-arch' option to the preprocessor. Like +this: + + ./configure CC="gcc -arch i386 -arch x86_64 -arch ppc -arch ppc64" \ + CXX="g++ -arch i386 -arch x86_64 -arch ppc -arch ppc64" \ + CPP="gcc -E" CXXCPP="g++ -E" + + This is not guaranteed to produce working output in all cases, you +may have to build one architecture at a time and combine the results +using the `lipo' tool if you have problems. + +Installation Names +================== + + By default, `make install' installs the package's commands under +`/usr/local/bin', include files under `/usr/local/include', etc. You +can specify an installation prefix other than `/usr/local' by giving +`configure' the option `--prefix=PREFIX'. + + You can specify separate installation prefixes for +architecture-specific files and architecture-independent files. If you +pass the option `--exec-prefix=PREFIX' to `configure', the package uses +PREFIX as the prefix for installing programs and libraries. +Documentation and other data files still use the regular prefix. + + In addition, if you use an unusual directory layout you can give +options like `--bindir=DIR' to specify different values for particular +kinds of files. Run `configure --help' for a list of the directories +you can set and what kinds of files go in them. + + If the package supports it, you can cause programs to be installed +with an extra prefix or suffix on their names by giving `configure' the +option `--program-prefix=PREFIX' or `--program-suffix=SUFFIX'. + +Optional Features +================= + + Some packages pay attention to `--enable-FEATURE' options to +`configure', where FEATURE indicates an optional part of the package. +They may also pay attention to `--with-PACKAGE' options, where PACKAGE +is something like `gnu-as' or `x' (for the X Window System). The +`README' should mention any `--enable-' and `--with-' options that the +package recognizes. + + For packages that use the X Window System, `configure' can usually +find the X include and library files automatically, but if it doesn't, +you can use the `configure' options `--x-includes=DIR' and +`--x-libraries=DIR' to specify their locations. + +Particular systems +================== + + On HP-UX, the default C compiler is not ANSI C compatible. If GNU +CC is not installed, it is recommended to use the following options in +order to use an ANSI C compiler: + + ./configure CC="cc -Ae" + +and if that doesn't work, install pre-built binaries of GCC for HP-UX. + + On OSF/1 a.k.a. Tru64, some versions of the default C compiler cannot +parse its `' header file. The option `-nodtk' can be used as +a workaround. If GNU CC is not installed, it is therefore recommended +to try + + ./configure CC="cc" + +and if that doesn't work, try + + ./configure CC="cc -nodtk" + +Specifying the System Type +========================== + + There may be some features `configure' cannot figure out +automatically, but needs to determine by the type of machine the package +will run on. Usually, assuming the package is built to be run on the +_same_ architectures, `configure' can figure that out, but if it prints +a message saying it cannot guess the machine type, give it the +`--build=TYPE' option. TYPE can either be a short name for the system +type, such as `sun4', or a canonical name which has the form: + + CPU-COMPANY-SYSTEM + +where SYSTEM can have one of these forms: + + OS KERNEL-OS + + See the file `config.sub' for the possible values of each field. If +`config.sub' isn't included in this package, then this package doesn't +need to know the machine type. + + If you are _building_ compiler tools for cross-compiling, you should +use the option `--target=TYPE' to select the type of system they will +produce code for. + + If you want to _use_ a cross compiler, that generates code for a +platform different from the build platform, you should specify the +"host" platform (i.e., that on which the generated programs will +eventually be run) with `--host=TYPE'. + +Sharing Defaults +================ + + If you want to set default values for `configure' scripts to share, +you can create a site shell script called `config.site' that gives +default values for variables like `CC', `cache_file', and `prefix'. +`configure' looks for `PREFIX/share/config.site' if it exists, then +`PREFIX/etc/config.site' if it exists. Or, you can set the +`CONFIG_SITE' environment variable to the location of the site script. +A warning: not all `configure' scripts look for a site script. + +Defining Variables +================== + + Variables not defined in a site shell script can be set in the +environment passed to `configure'. However, some packages may run +configure again during the build, and the customized values of these +variables may be lost. In order to avoid this problem, you should set +them in the `configure' command line, using `VAR=value'. For example: + + ./configure CC=/usr/local2/bin/gcc + +causes the specified `gcc' to be used as the C compiler (unless it is +overridden in the site shell script). + +Unfortunately, this technique does not work for `CONFIG_SHELL' due to +an Autoconf bug. Until the bug is fixed you can use this workaround: + + CONFIG_SHELL=/bin/bash /bin/bash ./configure CONFIG_SHELL=/bin/bash + +`configure' Invocation +====================== + + `configure' recognizes the following options to control how it +operates. + +`--help' +`-h' + Print a summary of all of the options to `configure', and exit. + +`--help=short' +`--help=recursive' + Print a summary of the options unique to this package's + `configure', and exit. The `short' variant lists options used + only in the top level, while the `recursive' variant lists options + also present in any nested packages. + +`--version' +`-V' + Print the version of Autoconf used to generate the `configure' + script, and exit. + +`--cache-file=FILE' + Enable the cache: use and save the results of the tests in FILE, + traditionally `config.cache'. FILE defaults to `/dev/null' to + disable caching. + +`--config-cache' +`-C' + Alias for `--cache-file=config.cache'. + +`--quiet' +`--silent' +`-q' + Do not print messages saying which checks are being made. To + suppress all normal output, redirect it to `/dev/null' (any error + messages will still be shown). + +`--srcdir=DIR' + Look for the package's source code in directory DIR. Usually + `configure' can determine that directory automatically. + +`--prefix=DIR' + Use DIR as the installation prefix. *Note Installation Names:: + for more details, including other options available for fine-tuning + the installation locations. + +`--no-create' +`-n' + Run the configure checks, but stop before creating any output + files. + +`configure' also accepts some other, not widely useful, options. Run +`configure --help' for more details. + diff --git a/Makefile.am b/Makefile.am new file mode 100644 index 0000000..1c902dc --- /dev/null +++ b/Makefile.am @@ -0,0 +1,39 @@ +# +# Copyright © 2003 Keith Packard, Noah Levitt +# +# Permission to use, copy, modify, distribute, and sell this software and its +# documentation for any purpose is hereby granted without fee, provided that +# the above copyright notice appear in all copies and that both that +# copyright notice and this permission notice appear in supporting +# documentation, and that the name of Keith Packard not be used in +# advertising or publicity pertaining to distribution of the software without +# specific, written prior permission.

Introduction + +The Xrender library is designed as a lightweight library interface to the +Render extension. This document describes how the library maps to the +protocol without duplicating the semantics described by that document. + +2. Data Types + +2.1 Primitive Types + +For resources represented as CARD32 or XID on the wire, Xrender exposes them +using an 'unsigned long' type as is the norm for 32-bit data objects in an +Xlib compatible API. + + typedef unsigned long Glyph; + typedef unsigned long GlyphSet; + typedef unsigned long Picture; + typedef unsigned long PictFormat; + +Glyphs are just CARD32 objects, while GlyphSet, Picture and PictFormat +values are XIDs. + + typedef int XFixed; + +Fixed point numbers buck the Xlib convention by being represented as ints. +Machines for which 'int' is smaller than 32 bits cannot support the Xrender +library. + +2.2 PictFormat descriptions. + +The definition of a PictFormat is exposed by two data structures: + + typedef struct { + short red; + short redMask; + short green; + short greenMask; + short blue; + short blueMask; + short alpha; + short alphaMask; + } XRenderDirectFormat; + + typedef struct { + PictFormat id; + int type; + int depth; + XRenderDirectFormat direct; + Colormap colormap; + } XRenderPictFormat; + +These serve both as a description of the available formats and as patterns +against which available formats are matched. + +2.3 Picture Attributes + +When creating or changing Picture objects, attributes are passed much as +they are for XCreateWindow/XChangeWindowAttributes. A structure capable of +holding all of the attributes has the relevant ones set and a bitmask passed +as a separate argument which marks the valid entries. + + typedef struct _XRenderPictureAttributes { + Bool repeat; + Picture alpha_map; + int alpha_x_origin; + int alpha_y_origin; + int clip_x_origin; + int clip_y_origin; + Pixmap clip_mask; + Bool graphics_exposures; + int subwindow_mode; + int poly_edge; + int poly_mode; + Atom dither; + Bool component_alpha; + } XRenderPictureAttributes; + +2.4 Colors + +The core protocol XColor type doesn't include an alpha component, so Xrender +has a separate type. + + typedef struct { + unsigned short red; + unsigned short green; + unsigned short blue; + unsigned short alpha; + } XRenderColor; + +2.5 Glyph Types + +Glyphs are stored in the server, so these definitions are passed from the +client to the library and on to the server as glyphs are rasterized and +transmitted over the wire. + + typedef struct _XGlyphInfo { + unsigned short width; + unsigned short height; + short x; + short y; + short xOff; + short yOff; + } XGlyphInfo; + +2.6 Glyph Rendering types + +Glyph rendering can either take a single string of glyph indices or an array +of one of the following structures. + + typedef struct _XGlyphElt8 { + GlyphSet glyphset; + _Xconst char *chars; + int nchars; + int xOff; + int yOff; + } XGlyphElt8; + + typedef struct _XGlyphElt16 { + GlyphSet glyphset; + _Xconst unsigned short *chars; + int nchars; + int xOff; + int yOff; + } XGlyphElt16; + + typedef struct _XGlyphElt32 { + GlyphSet glyphset; + _Xconst unsigned int *chars; + int nchars; + int xOff; + int yOff; + } XGlyphElt32; + +2.7 Geometric Types + +Geometric operations directly expose the available protocol datatypes + + typedef struct _XPointFixed { + XFixed x, y; + } XPointFixed; + + typedef struct _XLineFixed { + XPointFixed p1, p2; + } XLineFixed; + + typedef struct _XTriangle { + XPointFixed p1, p2, p3; + } XTriangle; + + typedef struct _XTrapezoid { + XFixed top, bottom; + XLineFixed left, right; + } XTrapezoid; + + typedef struct _XTransform { + XFixed matrix[3][3]; + } XTransform; + +2.8 Transformation Filters + +All of the filters are named simultaneously; Xrender provides no convenience +functions for dealing with them. + + typedef struct _XFilters { + int nfilter; + char **filter; + int nalias; + short *alias; + } XFilters; + +2.9 Index type PictFormat colors + +PictFormats of Index type advertise which colors will be used for drawing +through this type. + + typedef struct _XIndexValue { + unsigned long pixel; + unsigned short red, green, blue, alpha; + } XIndexValue; + + +3 Application Startup Functions + +3.1 Initialization functions + + Bool XRenderQueryExtension (Display *dpy, + int *event_basep, + int *error_basep) + +This function returns True if the Render extension is available on dpy. +event_basep and error_basep will be filled in with the first event and error +numbers used by the extension (note that Render currently uses no events). + + Status XRenderQueryVersion (Display *dpy, + int *major_versionp, + int *minor_versionp) + +XRenderQueryVersion returns zero if the Render extension is not present or +some error occurred while attempting to discover the current Render version +number. Otherwise, XRenderQueryVersion returns 1 and stores the version +number returned by the server in *major_versionp and *minor_versionp, which +will be less than or equal to the library version numbers RENDER_MAJOR and +RENDER_MINOR. + + Status XRenderQueryFormats (Display *dpy) + +XRenderQueryFormats returns 1 if it successfully fetches the available +PictFormat information from the X server, 0 otherwise. Applications needn't +invoke this function directly (hmm, perhaps it should be removed from the +external interfaces then). + +3.2 Subpixel Order + + int XRenderQuerySubpixelOrder (Display *dpy, int screen) + + Bool XRenderSetSubpixelOrder (Display *dpy, int screen, int subpixel) + +Applications interested in the geometry of the elements making up a single +pixel on the screen should use XRenderQuerySubpixelOrder and not cache the +return value. XRenderSetSubpixelOrder is used by the XRandR library to +update the value stored by Xrender when the subpixel order changes as a +result of screen reconfiguration. + +3.3 PictFormat matching + +Xrender provides these APIs to help locate appropriate PictFormats; they are +intended to work much like the Visual matching APIs in Xlib. The +application provides a specification including the necessary PictFormat +characteristics and Xrender returns a matching XRenderPictFormat structure +which describes the PictFormat. + + XRenderPictFormat * + XRenderFindFormat (Display *dpy, + unsigned long mask, + _Xconst XRenderPictFormat *templ, + int count) + + #define PictFormatID (1 << 0) + #define PictFormatType (1 << 1) + #define PictFormatDepth (1 << 2) + #define PictFormatRed (1 << 3) + #define PictFormatRedMask (1 << 4) + #define PictFormatGreen (1 << 5) + #define PictFormatGreenMask (1 << 6) + #define PictFormatBlue (1 << 7) + #define PictFormatBlueMask (1 << 8) + #define PictFormatAlpha (1 << 9) + #define PictFormatAlphaMask (1 << 10) + #define PictFormatColormap (1 << 11) + +XRenderFindFormat locates a PictFormat matching the characteristics provided +in the templ.

Otherwise, +XRenderQueryPictIndexValues generates a BadMatch error. + +3.5 Querying available filters + + XFilters * + XRenderQueryFilters (Display *dpy, Drawable drawable); + +Filters are used with non-identity transformation matrices, this function +returns a datastructure identifying the available filters on display that +can be associated with pictures for the screen associated with drawable. + +Free this structure with XFree. + +4 Picture Functions + + Picture + XRenderCreatePicture (Display *dpy, + Drawable drawable, + _Xconst XRenderPictFormat *format, + unsigned long valuemask, + _Xconst XRenderPictureAttributes *attributes) + + #define CPRepeat (1 << 0) + #define CPAlphaMap (1 << 1) + #define CPAlphaXOrigin (1 << 2) + #define CPAlphaYOrigin (1 << 3) + #define CPClipXOrigin (1 << 4) + #define CPClipYOrigin (1 << 5) + #define CPClipMask (1 << 6) + #define CPGraphicsExposure (1 << 7) + #define CPSubwindowMode (1 << 8) + #define CPPolyEdge (1 << 9) + #define CPPolyMode (1 << 10) + #define CPDither (1 << 11) + #define CPComponentAlpha (1 << 12) + #define CPLastBit 12 + +Creates a picture for drawable in the specified format.

The +two IDs refer to the same object so that changes using one ID will be +visible through the other ID. This is designed to allow multiple clients to +share the same GlyphSet so that it doesn't get destroyed when the first +client exits. + + void + XRenderFreeGlyphSet (Display *dpy, GlyphSet glyphset) + +Frees the glyphset ID. If no other GlyphSet IDs refer to the underlying +GlyphSet, it will be destroyed. + + void + XRenderAddGlyphs (Display *dpy, + GlyphSet glyphset, + _Xconst Glyph *gids, + _Xconst XGlyphInfo *glyphs, + int nglyphs, + _Xconst char *images, + int nbyte_images) + +Add glyphs to glyphset. The images are packed together in Z-pixmap format +according to the depth of the PictFormat used in creating glyphset. + + void + XRenderFreeGlyphs (Display *dpy, + GlyphSet glyphset, + _Xconst Glyph *gids, + int nglyphs) + +Free some glyphs from glyphset. + +6 Glyph Drawing Routines + +Xrender provides two parallel APIs for glyph rendering, a simple API which +accepts a single string similar to XDrawString and a more complex API which +accepts an array of XGlyphElt{8,16,32} structures, each of which includes a +glyphset, string and x/y offsets which parallel the XDrawText API. Xrender +also provides glyphs in three sizes, 8 16 and 32 bits. The simple API is +just a convenience for the user as both forms generate the same underlying +Render protocol. + +6.1 Simple single-string glyph drawing functions + +These are identical except for the format of the glyph ids. + + void + XRenderCompositeString8 (Display *dpy, + int op, + Picture src, + Picture dst, + _Xconst XRenderPictFormat *maskFormat, + GlyphSet glyphset, + int xSrc, + int ySrc, + int xDst, + int yDst, + _Xconst char *string, + int nchar) + + void + XRenderCompositeString16 (Display *dpy, + int op, + Picture src, + Picture dst, + _Xconst XRenderPictFormat *maskFormat, + GlyphSet glyphset, + int xSrc, + int ySrc, + int xDst, + int yDst, + _Xconst unsigned short *string, + int nchar) + + void + XRenderCompositeString32 (Display *dpy, + int op, + Picture src, + Picture dst, + _Xconst XRenderPictFormat *maskFormat, + GlyphSet glyphset, + int xSrc, + int ySrc, + int xDst, + int yDst, + _Xconst unsigned int *string, + int nchar) + +6.2 Complete glyph drawing functions + +As with the simple functions above, these differ only in the type of the +underlying glyph id storage type. + + void + XRenderCompositeText8 (Display *dpy, + int op, + Picture src, + Picture dst, + _Xconst XRenderPictFormat *maskFormat, + int xSrc, + int ySrc, + int xDst, + int yDst, + _Xconst XGlyphElt8 *elts, + int nelt) + + void + XRenderCompositeText16 (Display *dpy, + int op, + Picture src, + Picture dst, + _Xconst XRenderPictFormat *maskFormat, + int xSrc, + int ySrc, + int xDst, + int yDst, + _Xconst XGlyphElt16 *elts, + int nelt) + + void + XRenderCompositeText32 (Display *dpy, + int op, + Picture src, + Picture dst, + _Xconst XRenderPictFormat *maskFormat, + int xSrc, + int ySrc, + int xDst, + int yDst, + _Xconst XGlyphElt32 *elts, + int nelt) + +7 Basic Graphics Functions + +These are the simplest graphics functions upon which the other functions are +conceptually built. + +7.1 Composite + +XRenderComposite exposes the RenderComposite protocol request directly. + + void + XRenderComposite (Display *dpy, + int op, + Picture src, + Picture mask, + Picture dst, + int src_x, + int src_y, + int mask_x, + int mask_y, + int dst_x, + int dst_y, + unsigned int width, + unsigned int height) + + +7.2 Rectangles + +These functions composite rectangles of the specified color, they differ +only in that XRenderFillRectangles draws more than one at a time. + + void + XRenderFillRectangle (Display *dpy, + int op, + Picture dst, + _Xconst XRenderColor *color, + int x, + int y, + unsigned int width, + unsigned int height) + + void + XRenderFillRectangles (Display *dpy, + int op, + Picture dst, + _Xconst XRenderColor *color, + _Xconst XRectangle *rectangles, + int n_rects) + +8 Geometric Objects + +All geometric drawing with Render is performed with sequences of trapezoids +or triangles; the client is responsible for breaking more complex figures +into these simple shapes. + +8.1 Trapezoids + + void + XRenderCompositeTrapezoids (Display *dpy, + int op, + Picture src, + Picture dst, + _Xconst XRenderPictFormat *maskFormat, + int xSrc, + int ySrc, + _Xconst XTrapezoid *traps, + int ntrap) + +XRenderCompositeTrapezoids builds RenderTrapezoids requests to composite the +specified list of trapezoids to dst. XRenderCompositeTrapezoids will split +the list of trapezoids to build requests no larger than the maximum request +size supported by the server. This can create rendering artifacts as the +precompositing done by RenderTrapezoids when a maskFormat is specified +cannot span multiple requests. + +8.2 Triangles + +Render provides three different ways of encoding triangles on the wire, +Xrender exposes those with three separate triangle drawing routines. As +with trapezoids above, Xrender will split the arguments to fit requests into +the servers limits, but this may cause rendering artifacts. diff --git a/include/X11/extensions/Xrender.h b/include/X11/extensions/Xrender.h new file mode 100644 index 0000000..1d1cd08 --- /dev/null +++ b/include/X11/extensions/Xrender.h @@ -0,0 +1,528 @@ +/* + * + * Copyright © 2000 SuSE, Inc. + * + * Permission to use, copy, modify, distribute, and sell this software and its + * documentation for any purpose is hereby granted without fee, provided that + * the above copyright notice appear in all copies and that both that + * copyright notice and this permission notice appear in supporting + * documentation, and that the name of SuSE not be used in advertising or + * publicity pertaining to distribution of the software without specific, + * written prior permission.
