* pattern: Restore dropped inclusion of cairoint.h1.14.0Bryce Harrington2014-10-131-0/+2
| | | | | Fixes failure in make release-check due by check-preprocessor-syntax.sh due to requirement that cairoint.h be the first include for source files.

* pdf: don't use '\' to split strings across multiple linesAdrian Johnson2014-10-121-1/+1
| | | | | The PDF interpreter in my printer does not handle this correctly. So instead we add the string delimiters '(' and ')' to each line.
* image: Corrected extents calculationsBill Spitzak2014-10-106-153/+176
| | | | | | | | | | | | New implementations of _cairo_pattern_sampled_area and _cairo_pattern_get_extents which produce a more accurate bounding box. These do not depend on side-effects of analyze_filter, can handle different horizontal and vertical scales, filters wider than 1 for down-scaling, and compute a somewhat tighter bounding box in most cases. I removed the pad output of _cairo_pattern_analyze_filter as it is unused. Reviewed-by: Bryce Harrington <b.harrington@samsung.com>
* xcb: Use image fallback for GOOD/BEST filtersBill Spitzak2014-10-101-18/+16
| | | | | | | | | | | It will not use the fallback if the symbols in the previous patch are turned on. Also some code rearrangement to make this resemble the xlib version more and to remove some suspect bugs. In particular meshes should not work just because the translation is an integer.

* xcb: Add switches for whether XRender supports GOOD/BEST filteringBill Spitzak2014-10-102-1/+15
| | | | | | | Currently these are always false, but if XRender use a pixman that supports filtering these could be turned on for that version. Reviewed-by: Bryce Harrington <b.harrington@samsung.com>
* xlib: Use image fallback for GOOD/BEST filtersBill Spitzak2014-10-101-9/+14
| | | | | | | | | | | Fallback is not used if the symbols defined in the previous patch to indicate if XRender does GOOD/BEST are true. This patch also includes some changes to take advantage of the fact that if there is an integer translation analyze_filter will already have set the filter to NEAREST.

* image: Move filter decision to _cairo_pattern_analyze_filterBill Spitzak2014-10-102-14/+44
| | | | | | | | The analysis to deterimine if the GOOD filter can be replaced with the BILINEAR filter is moved to this function so it can be used by backends other than the image backend. Reviewed-by: Bryce Harrington <b.harrington@samsung.com>
* test: Update pixman downscaling 95 reference imagesBryce Harrington2014-10-0949-0/+0
| | | | | | | | | | | | | | The pixman downscaling "95" tests attempt to rescale a 96x96 pixmap to 95x95. Ideally the borders between color areas should be sharp, but for this use case we allow for 1 pixel of blur between the areas as acceptable. The choice of what color to use for this blurred region is not important, and in fact varies from backend to backend. The old reference images were generated by Krzysztof Kosiński's downscaling algorithm. These new images are against the algorithms written by Bill Spitzak.

* test: Add an update-refs.sh script to update reference imagesBryce Harrington2014-10-091-0/+84
| | | | | | | | | | | | | | | | | | There are cases where the rendered output of a test can vary from backend to backend in ways which are visually acceptable. This is why we have reference images in the first place. In these cases, changes to the rendering logic can result in slight differences in the output that is also within acceptable visual limits. We see this in the pixman downscaling tests. This script is introduced as a way to more easily update the reference images after a renderer change. This script is intended to be expanded to handle updating of references for other tests as we identify similar issues. The intent is that this script then serves as a way to document these exceptional cases. Signed-off-by: Bryce Harrington <bryce@osg.samsung.com>

* test: Add whole flipped replaysChris Wilson2014-10-0210-0/+188
| | | | | | | | | When investing the symmetry of the raterisation, we want to have a simple replay of all of the original geometry through a the flipped recording surface. This reduces the worry about artifacts from the clipped rendering. Signed-off-by: Chris Wilson <chris@chris-wilson.co.uk>
* image: Eliminate self-intersections for the pixman traps compositorChris Wilson2014-10-021-0/+32

* tor: Enable analytic processing for starting rowsChris Wilson2014-10-021-10/+17
| | | | | | | | | If all the edges start at the very beginning of the whole row, we can merge them and include check for intersections/endings during the row.

* tor: Perform analytic coverage over the pixel not sample pointsChris Wilson2014-10-021-18/+49
| | | | | | | | | | | | | | | | | | | | | | | | We use two different methods within tor to compute the coverage. The first is that we iterate over every sample point within the pixel and see if it is covered. The second is that we look at a whole pixel and analytically compute the coverage inside (if we have no intersections within that row). One side effect of commit 03c3d4b7c159a3004071522bac2461e553fec211 Author: Chris Wilson <chris@chris-wilson.co.uk> Date: Tue Sep 30 08:44:43 2014 +0100 tor: Fix loss of precision from projection onto sample grid was to compute our X coordinates for the sample locations (offset by half a subrow) and that in order to compute the analytical pixel coverage correctly, we therefore need to backstep by half the subrow to the pixel boundary.

* stroke,traps: Emit join without loss of precisionChris Wilson2014-09-298-257/+530
| | | | | | | | | | | | | | As the target renderers operate at a different sample resolution then we use internally for coordinate representation, there is always a potential for discrepancies in the line gradients when passing around trapezoids. To overcome this, the protocol specification of trapezoids uses the full lines and vertical range as opposed to vertices and so long as we always use the same lines for conjoint trapezoids, they remain abutting in the rasteriser.

* test/coverage: Exercise invariance under mirror symmetryChris Wilson2014-09-292-0/+55
| | | | | | | | | | | | | Massimo noticed that the record/record-flip were not being rasterised as identical mirror images due to a half-subpixel offset in the tor scan converter. This test attempts to reproduce this error by rendering a rhombus around the origin of each cell (that is it generates 4 mirror images of a triangle in the 4 different orientations0. The expectation is that each pixel in the group is lit identically as the coverage is identical.

* build: Fix float endian configure test when using clang -O4Bryce Harrington2014-09-231-4/+5
| | | | | | | | | | | | | | | | | When using clang -O4, the compiled test object is output in bitcode format rather than as an ELF object, so when we grep the test value from the object it fails. To work around this, go ahead and link the test object into an executable, and then grep against this native binary instead of the compiler's intermediary object. We need to add __attribute__((used)) to ensure the d variable doesn't get optimized out during linking, since it's not referenced in the test's main().
