From a856371bef496da0e84226f4fd2fc3cb72e955ac Mon Sep 17 00:00:00 2001 From: Chris Wilson Date: Tue, 4 Nov 2008 10:45:34 +0000 Subject: Add CairoScript backend. A new meta-surface backend for serialising drawing operations to a CairoScript file. The principal use (as currently envisaged) is to provide a round-trip testing mechanism for CairoScript - i.e. we can generate script files for every test in the suite and check that we can replay them with perfect fidelity. (Obviously this does not provide complete coverage of CairoScript's syntax, but should give reasonable coverage over the operators.) --- boilerplate/Makefile.sources | 3 + boilerplate/cairo-boilerplate-script-private.h | 57 + boilerplate/cairo-boilerplate-script.c | 125 ++ boilerplate/cairo-boilerplate.c | 16 + build/configure.ac.features | 2 + configure.ac | 16 + doc/public/tmpl/cairo-surface.sgml | 1 + src/Makefile.sources | 3 + src/cairo-base85-stream.c | 1 + src/cairo-cache-private.h | 2 +- src/cairo-cache.c | 41 +- src/cairo-deflate-stream.c | 1 + src/cairo-ft-font.c | 12 + src/cairo-ft-private.h | 3 + src/cairo-gstate.c | 3 +- src/cairo-output-stream-private.h | 19 +- src/cairo-output-stream.c | 43 +- src/cairo-path-fixed-private.h | 11 + src/cairo-path-fixed.c | 164 ++ src/cairo-pattern.c | 255 +++ src/cairo-pdf-operators.c | 1 + src/cairo-ps-surface.c | 2 + src/cairo-scaled-font-private.h | 9 +- src/cairo-scaled-font.c | 5 + src/cairo-script-surface.c | 2598 ++++++++++++++++++++++++ src/cairo-script.h | 74 + src/cairo-types-private.h | 1 + src/cairo.h | 4 +- src/cairoint.h | 18 + test/Makefile.am | 4 +- test/any2ppm.c | 87 +- test/mime-data.script.ref.png | Bin 0 -> 1982 bytes 32 files changed, 3540 insertions(+), 41 deletions(-) create mode 100644 boilerplate/cairo-boilerplate-script-private.h create mode 100644 boilerplate/cairo-boilerplate-script.c create mode 100644 src/cairo-script-surface.c create mode 100644 src/cairo-script.h create mode 100644 test/mime-data.script.ref.png diff --git a/boilerplate/Makefile.sources b/boilerplate/Makefile.sources index 44eeb39b..7be44672 100644 --- a/boilerplate/Makefile.sources +++ b/boilerplate/Makefile.sources @@ -36,6 +36,9 @@ cairo_boilerplate_ps_sources = cairo-boilerplate-ps.c cairo_boilerplate_quartz_private = cairo-boilerplate-quartz-private.h cairo_boilerplate_quartz_sources = cairo-boilerplate-quartz.c +cairo_boilerplate_script_private = cairo-boilerplate-script-private.h +cairo_boilerplate_script_sources = cairo-boilerplate-script.c + cairo_boilerplate_sdl_private = cairo-boilerplate-sdl-private.h cairo_boilerplate_sdl_sources = cairo-boilerplate-sdl.c diff --git a/boilerplate/cairo-boilerplate-script-private.h b/boilerplate/cairo-boilerplate-script-private.h new file mode 100644 index 00000000..480e4221 --- /dev/null +++ b/boilerplate/cairo-boilerplate-script-private.h @@ -0,0 +1,57 @@ +/* -*- Mode: c; c-basic-offset: 4; indent-tabs-mode: t; tab-width: 8; -*- */ +/* + * Copyright © 2008 Chris Wilson + * + * 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 + * Red Hat, Inc. not be used in advertising or publicity pertaining to + * distribution of the software without specific, written prior + * permission.
