2010-06-22gl: Return a surface from _cairo_surface_create_in_error()Benjamin Otte1-1/+2
On error, surface creation functions should always return a surface created with _cairo_surface_create_in_error() instead of a new surface in an error state. This simplifies internal code as no refcounting has to be done.
2010-06-22gl: Propagate surface creation error instead of crashingBenjamin Otte1-6/+16
2010-06-22egl: Copy glx code to detect the proper surface in acquireBenjamin Otte1-0/+9
2010-06-22egl: Remove unused prev_foo usageBenjamin Otte1-7/+0
2010-06-19script: Pass the buffer length back to freetype.Chris Wilson1-1/+1
After querying the required size, inform the backend of the allocated size of the buffer.
2010-06-19xcb: Return the status upon flushing the device.Chris Wilson1-2/+3
The vfunc was updated to expect the status return, so supply it.
2010-06-19xlib: Precise and Imprecise were reversed.Chris Wilson1-4/+4
The intention was to switch to imprecise mode by default, using the exact rendering mode only upon request.
2010-06-19xlib: Perform image uploads inplace.Chris Wilson1-0/+112
Under the restrictive conditions where we are doing an untransformed contained upload of an image into a matching surface, perform it in place. The drivers will attempt to stream such uploads efficiently, far more so than our code.
2010-06-18egl: Fail properly if no configs are available instead of crashingBenjamin Otte1-0/+4
2010-06-18glx: Remove useless optimization trying to avoid glXMakeCurrent()Benjamin Otte1-17/+2
The optimization is not performance-relevant. And having less code is always a good idea.
2010-06-18gl: Refactor status handling in _cairo_gl_context_release()Benjamin Otte6-43/+43
Previously, the code returned a status and required the caller to mangle this status with his own status. Now, the function takes the previous status ass an argument and does the mangling itself. Also contains fixes for all the callers to actually check the return value - which is now rather trivial as it just requires passing through the status variable.
2010-06-18gl: Inline the check_error() functionBenjamin Otte1-16/+7
2010-06-18gl: Don't assert if there used to be a GL errorBenjamin Otte1-1/+2
When acquiring the GL context, do not assert that the GL context is not in an error state. Do not even call _cairo_error(). Handling GL errors in other code is not Cairo's responsibility. Instead just clear all previous errors so we don't accidentally set surfaces into error states to unrelated errors.
2010-06-18gl: Add a custom glGetError() functionBenjamin Otte1-3/+16
This function clears all errors and returns the first one that happened.
2010-06-18gl: Remove custom fprintf fudging on GL errorsBenjamin Otte2-26/+1
Now that we probably call _cairo_error() on every GL error, there is no need to use custom methods to catch those errors. The usual breakpoint is enough.
2010-06-18gl: cairo_warn about return value from cairo_gl_context_release()Benjamin Otte1-1/+1
2010-06-18boilerplate: Reinstate glFinish() for wglBenjamin Otte1-1/+1
It was accidentally disabled.
2010-06-18egl: Implement acquire and release for EGL backendKristian Høgsberg1-9/+37
2010-06-17image: Make a local copy of the trap coordinates as the boxes alias.Chris Wilson1-4/+11
As we transform the array of trapezoids into an array of boxes in-place, we must take local copies of the coordinates before writing into the boxes otherwise we may inadvertently modify the trapezoidal coordinates. Fixes test/a1-bug.
2010-06-17test: Add a1-bugChris Wilson6-0/+65
Capture a bug report from "cairouser" where a1 rasterisation is now broken.
2010-06-17perf: Allow comparing perf reports with only one difference.M Joonas Pihlaja1-1/+1
The cairo-perf-diff-files tool would ignore perf reports with just one test for no apparent reason. The traces take so long that it's useful to be able to compare runs with just one trace.
2010-06-17test/halo: Remove copied code.Chris Wilson1-36/+0
How did that get there? I obviously ran the test to generate the output, so where did it spring as it is the old version of the function? From 16364768d79570e7201a87f0a985c65acaff5560. Mysteries will never cease.
2010-06-17wgl: Only reset GL context on the dummy window.Zoxc1-4/+2
This changes the WGL context destruction code to only reset the GL context for the dummy window, since doing it on <nothing> is an invalid operation.
2010-06-17gl: Added wgl boilerplate and moved the glx and egl boilerplates into their ↵Zoxc7-92/+397
own files.
2010-06-17wgl: Renamed hwnd field to wnd.Zoxc1-6/+6
2010-06-17ft,fc,xlib: LCD filtering patch.Nicolaus L Helper6-190/+597
This adds internal API to retrieve the LCD filtering parameters from fontconfig, or as set on the Screen, and feed them to FreeType when rendering the glyph. References: Bug 10301 - LCD filtering patch https://bugs.freedesktop.org/show_bug.cgi?id=10301 Tested-by: Brandon Wright <bearoso@gmail.com> Forward-ported-by: Robert Hooker <sarvatt@gmail.cm> ickle: The API is clearly not ready for public consumption, the enum are poorly named, however this stands by itself as enabling system wide properties.
2010-06-17image: Use consistent rounding modes for a1 rasterisation.Chris Wilson1-23/+35
When checking if the traps are equivalent to a set of rectangles, we need to use the same rounding mode as when converting the traps to a set of boxes and then filling them. Failure to do leads to a situation where (-127,-128) was thought to be equivalent to (0,0) but we attempted to fill from 0 to -1 instead.

2010-06-17fixed: Refactor code to use more inlines and less duplication of logic.Chris Wilson1-3/+15
This also has the side-effect of fixing the types in the problematic functions which hid Andrea's true fix for the unsigned FRAC_MASK.
2010-06-17test: Add a1-rasterisationChris Wilson5-0/+104
Check the rounding criteria when rasterising.
2010-06-17test/halo: Transformation seems key to the bug...Chris Wilson1-0/+36
2010-06-17test: correct options in getopt callAndrea Canciani1-1/+1
'k' was missing and 't' was present but unhandled. Options have been reordered according to the "USAGE" ordering.
2010-06-16correct rounding computationAndrea Canciani1-1/+1
cairo_fixed_integer_round[_down] were adding an unsigned mask value before shifting its result, causing the shift to be computed as logical (unsigned) right shift, thus producing incorrect values for negative inputs. Making the mask value signed fixes this issue. Bug report by cu: http://lists.cairographics.org/archives/cairo/2010-June/020115.html
2010-06-16test/halo: Transformation seems key to the bug...Chris Wilson10-2/+67
Only it is actually transformation of the result that is required in order to magnify the effect to a detectable level.
2010-06-15test/aliasing: Add a few more colour combinations.Chris Wilson4-1/+5
In particular, compare red against its inverse, cyan. Etc.
2010-06-15configure: Try an alternate name for system glew.Chris Wilson1-4/+6
2010-06-15build: Enable system GLEW on non-UNIX platformsChris Wilson1-3/+9
2010-06-15glew: Define NULLChris Wilson1-0/+4
2010-06-14test: Add an aliasing test case.Chris Wilson6-0/+102
Just a simple test in drawing neighbouring edges and looking for the effects of aliasing.
2010-06-14test: Add haloChris Wilson6-0/+102
halo uses text_path + stroke + (fill | show_text) to generate a "halo" around the string. This is to try to replicate a bug described by Ian Britten in the PDF backend where the rendering of the show_text looked distorted compared to the stroke.
2010-06-14build: Add wgl to Makefile.sources and regenerate features.Chris Wilson5-2/+32
2010-06-14scaled-font: fine-tune cachingDmitri Vorobiev1-16/+45
This patch implements the ideas outlined by Behdad Esfahbod in the following mailing list message: http://lists.cairographics.org/archives/cairo/2010-June/020065.html Specifically, two things have been adjusted. First, the size of the look-up table was reduced to 64. Second, cache codepath is now bypassed for strings that are shorter than 16, not only for one-character strings. This allowed us to reduce the LUT initialization overhead while still retaining the advantage of caching for common-case string sizes. We have experimented with different LUT sizes, and it came out that the size of 64 is the best one in view of speed, at least for our language-neutral benchmark, which generated random strings of printable ASCII characters. Below is a table presenting benchmark results for different values of LUT size: =============================================================================== Benchmark | [1] | [2] | [3] | [4] | [5] | [6] | [7] =============================================================================== 8px text, 1 chars | 0.41 | 0.41 | 0 | 0.41 | 0 | 0.41 | 0 8px text, 10 chars | 2.13 | 2.21 | 3.76 | 2.19 | 2.82 | 2.09 | -1.88 8px text, 20 chars | 2.97 | 3.04 | 2.36 | 3.01 | 1.35 | 2.98 | 0.34 12px text, 1 chars | 0.94 | 0.94 | 0 | 0.95 | 1.06 | 0.94 | 0 12px text, 10 chars | 4.73 | 4.89 | 3.38 | 4.9 | 3.59 | 4.82 | 1.9 12px text, 20 chars | 6.32 | 6.42 | 1.58 | 6.46 | 2.22 | 6.32 | 0 16px text, 1 chars | 1.75 | 1.76 | 0.57 | 1.77 | 1.14 | 1.76 | 0.57 16px text, 10 chars | 8.13 | 8.45 | 3.94 | 8.43 | 3.69 | 8.44 | 3.81 16px text, 20 chars | 10.41 | 10.69 | 2.69 | 10.64 | 2.21 | 10.65 | 2.31 24px text, 1 chars | 3.3 | 3.3 | 0 | 3.32 | 0.61 | 3.3 | 0 24px text, 10 chars | 14.68 | 14.97 | 1.98 | 14.97 | 1.98 | 14.87 | 1.29 24px text, 20 chars | 17.93 | 18.01 | 0.45 | 18.06 | 0.73 | 17.81 | -0.67 96px text, 1 chars | 23.65 | 23.38 | -1.14 | 23.74 | 0.38 | 23.65 | 0 96px text, 5 chars | 50.52 | 51.34 | 1.62 | 51.48 | 1.9 | 51.41 | 1.76 96px text, 10 chars | 57.5 | 58.11 | 1.06 | 58.27 | 1.34 | 58.04 | 0.94 =============================================================================== [1]: Git head, Mpix/s [2]: {GLYPH_LUT_SIZE = 32, CACHING_THRESHOLD = 16} [3]: Gain of {32, 16} w.r.t.
