* Defining Windows version macros in meson.buildFujii Hironori2023-01-131-9/+0
| | | | | | | | | WINVER and _WIN32_WINNT macros were defined in each source files and headers that were including <windows.h>. However, because DirectWrite requires new Windows API, some files included <windows.h> without the version macros. This inconsistency sometimes caused troubles. Define the version macros in meson.build.

* Use _cairo_malloc instead of mallocAdrian Johnson2018-05-071-1/+1
| | | | | | | | | | _cairo_malloc(0) always returns NULL, but has not been used consistently. This patch replaces many calls to malloc() with _cairo_malloc().

* Use strtod_l when availableMatthias Clasen2017-12-191-0/+37
| | | | | | Using strtod_l and newlocale is a nicer way to have provide a C-locale-only strtod. Since these APIs are not available everywhere, keep the old code as a fallback.
* Make _intern_string_hash non-staticMatthias Clasen2017-12-191-3/+3
| | | | | We will use this function in cairo-font-options.c in the following commits.
* Make _intern_string_hash safe for ""Matthias Clasen2017-12-191-1/+1
| | | | | | The loop was unnecessarily written in a way that fails to terminate if len is 0 (ie for the empty string). Avoid that by checking for len > 0 explicitly.
* Use UTF-8 filenames on WindowsTom Schoonjans2017-11-261-0/+62
| | | | | | | | | | | Until now fopen was used on Windows to open files for reading and writing. This assumed however that the filename would be encoded in the current codepage, which is a major inconvenience and makes it even impossible to use filenames that use characters from more than one codepage. This patch enforces the use of UTF-8 filenames on all platforms. Based on the work of Owen Taylor (https://lists.cairographics.org/archives/cairo/2007-February/009591.html)

* pdf: support JBIG2 mime dataAdrian Johnson2013-09-151-0/+2
| | | | | | | | | | JBIG2 images may have shared global data that is stored in a separate stream in PDF. The CAIRO_MIME_TYPE_JBIG2 mime type is for the JBIG2 data for each image. All images that use global data must also set CAIRO_MIME_TYPE_JBIG2_GLOBAL_ID to a unique identifier. One of the images must also set CAIRO_MIME_TYPE_JBIG2_GLOBAL to the global data. The global data will be shared by all JBIG2 images with the same CAIRO_MIME_TYPE_JBIG2_GLOBAL_ID.
* doc: Add "since" tag to documentationAndrea Canciani2012-03-291-0/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The following Python script was used to compute "Since: 1.X" tags, based on the first version where a symbol became officially supported. This script requires a concatenation of the the cairo public headers for the officially supported beckends to be available as "../../includes/1.X.0.h". from sys import argv import re syms = {} def stripcomments(text): def replacer(match): s = match.group(0) if s.startswith('/'): return "" else: return s pattern = re.compile( r'//.*?$|/\*.*?\*/|\'(?:\\.|[^\\\'])*\'|"(?:\\.|[^\\"])*"', re.DOTALL | re.MULTILINE ) return re.sub(pattern, replacer, text) for minor in range(12,-2,-2): version = "1.%d" % minor names = re.split('([A-Za-z0-9_]+)', stripcomments(open("../../includes/%s.0.h" % version).read())) for s in names: syms[s] = version for filename in argv[1:]: is_public = False lines = open(filename, "r").read().split("\n") newlines = [] for i in range(len(lines)): if lines[i] == "/**": last_sym = lines[i+1][2:].strip().replace(":", "") is_public = last_sym.lower().startswith("cairo") elif is_public and lines[i] == " **/": if last_sym in syms: v = syms[last_sym] if re.search("Since", newlines[-1]): newlines = newlines[:-1] if newlines[-1].strip() != "*": newlines.append(" *") newlines.append(" * Since: %s" % v) else: print "%s (%d): Cannot determine the version in which '%s' was introduced" % (filename, i, last_sym) newlines.append(lines[i]) out = open(filename, "w") out.write("\n".join(newlines)) out.close()
* doc: Make documentation comments symmetricAndrea Canciani2012-03-291-7/+7
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Documentation comments should always start with "/**" and end with "**/". This is not required by gtk-doc, but it makes the documentations formatting more consistent and simplifies the checking of documentation comments. The following Python script tries to enforce this. from sys import argv from sre import search for filename in argv[1:]: in_doc = False lines = open(filename, "r").read().split("\n") for i in range(len(lines)): ls = lines[i].strip() if ls == "/**": in_doc = True elif in_doc and ls == "*/": lines[i] = " **/" if ls.endswith("*/"): in_doc = False out = open(filename, "w") out.write("\n".join(lines)) out.close() This fixes most 'documentation comment not closed with **/' warnings by check-doc-syntax.awk.

* misc: Only use custom lround() under DISABLE_SOME_FLOATING_POINTChris Wilson2010-01-221-0/+2
| | | | | | | | | | On my Core2, the library version of lround() is faster than our hand-rolled non-floating point implementation. So only enable our code if we are trying to minimise the number of floating point operations -- even then, it would worth investigating the library performance first. [Just a reminder that optimisation choices will change over time as our hardware and software evolves.]
* drm: Add backends for i915 and i965.Chris Wilson2010-01-221-0/+57
| | | | | | | | | | | | | As proof-of-principle add the nearly working demonstrations of using DRM to render directly with the GPU bypassing both RENDER and GL for performance whilst preserving high quality rendering. The basis behind developing these chip specific backends is that this is the idealised interface that we desire for this chips, and so a target for cairo-gl as we continue to develop both it and our GL stack. Note that this backends do not yet fully pass the test suite, so only use if you are brave and willing to help develop them further.
* Alter definition of cairo_composite_rectangles_tChris Wilson2010-01-221-0/+41
| | | | | | | This is a more useful definition that is able to individually track the rectangles that compose the composite operation. This will be used by the specialist compositors as a means to perform the common extents determination for an operation.
* Add cairo_device_tChris Wilson2010-01-221-0/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The device is a generic method for accessing the underlying interface with the native graphics subsystem, typically the X connection or perhaps the GL context. By exposing a cairo_device_t on a surface and its various methods we enable finer control over interoperability with external interactions of the device by applications. The use case in mind is, for example, a multi-threaded gstreamer which needs to serialise its own direct access to the device along with Cairo's across many threads. Secondly, the cairo_device_t is a unifying API for the mismash of backend specific methods for controlling creation of surfaces with explicit devices and a convenient hook for debugging and introspection. The principal components of the API are the memory management of: cairo_device_reference(), cairo_device_finish() and cairo_device_destroy(); along with a pair of routines for serialising interaction: cairo_device_acquire() and cairo_device_release() and a method to flush any outstanding accesses: cairo_device_flush(). The device for a particular surface may be retrieved using: cairo_surface_get_device(). The device returned is owned by the surface.
* Move _cairo_error() to a standalone headerChris Wilson2010-01-221-0/+1
| | | | | A pending commit will want to include some utility code from cairo and so we need to extricate the error handling from the PLT symbol hiding.
* Use new pixman extended blend operatorsBenjamin Otte2009-07-141-0/+30
| | | | | | It also adds extended-blend tests. Based on a previous patch by Emmanuel Pacaud <emmanuel.pacaud@free.fr>
* [cairo] Tweak error strings.Chris Wilson2009-06-031-6/+6
| | | | | | Rewrite a few error strings so that they more closer match the documentation. Where they differ, I believe I have chosen the more informative combination of the two texts.
* [user-font] Add CAIRO_STATUS_USER_FONT_NOT_IMPLEMENTEDBehdad Esfahbod2009-05-061-0/+2
| | | | | This is useful for language bindings to signal that a method is not implemented.
* [memfault] Manually inject faults when using stack allocationsChris Wilson2009-04-231-0/+3
| | | | | | | | | | Ensure that no assumptions are made that a small allocation will succeed by manually injecting faults when we may be simply allocating from an embedded memory pool. The main advantage in manual fault injection is improved code coverage - from within the test suite most allocations are handled by the embedded memory pools.
* Silence compiler warnings for CAIRO_STATUS_LAST_STATUSChris Wilson2009-03-291-2/+3
| | | | | Add ASSERT_NOT_REACHED (or similar) cases to the error handling switches to silence the compiler.

* [wince] We don't need cairo_win32_tmpfile on Windows CEJeff Muizelaar2009-02-131-1/+4
| | | | | | | _cairo_win32_tmpfile() uses _open_osfhandle() which is not available on Windows CE. However, Windows CE doesn't have the permisions problems that necessitated _cairo_win32_tmpfile() in the first place so we can just use tmpfile() on Windows CE.
* Inline _cairo_restrict_value()Chris Wilson2009-02-131-9/+0

* [surface] add CAIRO_STATUS_INVALID_SIZEPaolo Bonzini2009-01-291-1/+3
| | | | | | | | Adds an error code replacing CAIRO_STATUS_NO_MEMORY in one case where it is not really appropriate. CAIRO_STATUS_INVALID_SIZE is used by several backends that do not support image sizes beyond 2^15 pixels on each side. Signed-off-by: Chris Wilson <chris@chris-wilson.co.uk>
