2011-08-10test: Add record-extendChris Wilson7-0/+225
Exercise the extend modes with a clipped paint, because once upon a time we had a bug... Signed-off-by: Chris Wilson <chris@chris-wilson.co.uk>
2011-08-10recording: do not reduce required clipsChris Wilson2-1/+3
When painting with an unbound source, we would miss that the clip extents were smaller than the mask extents and remove the solitary clip (believing we were bound by a tight mask). For painting this is obviously wrong, and due to a combination of bugs that set the mask to the bound extents and then the failure to spot when that mask was larger than the clip.

2011-08-10trace: Pop the surface after write-to-pngChris Wilson1-2/+2
It is convenient if the user can simply enable the use of the commented write-to-png operation just by removing the preceding '%'. However, to do so we need to make sure that the line is stack-neutral and so need to pop the surface that we place onto the stack after writing the png.

2011-08-10fixed: Allow the implicit close of the last fill path to complete a fill-boxChris Wilson1-4/+4
Signed-off-by: Chris Wilson <chris@chris-wilson.co.uk>
2011-08-10tor: update is-vertical along with min-heightChris Wilson1-14/+10
Similar to the minimum height property, is-vertical can only change after an insertion or deletion event. So we only need to update the flags after one of those events, so simply update it along side min-height. Signed-off-by: Chris Wilson <chris@chris-wilson.co.uk>
2011-08-09perf: add curveChris Wilson4-0/+111
Time how long it takes to stroke and fill a single Bezier curve. Signed-off-by: Chris Wilson <chris@chris-wilson.co.uk>
2011-08-09perf: add many-curvesChris Wilson4-0/+122
Continuing the theme of stressing the tessellators, draw lots of Bezier curves! Signed-off-by: Chris Wilson <chris@chris-wilson.co.uk>
2011-08-09tor: Fix mergesort to handle doubly-linked listChris Wilson1-22/+14
Signed-off-by: Chris Wilson <chris@chris-wilson.co.uk>
2011-08-09tor: trivial changesChris Wilson1-9/+5
Some trivial cleanups that escaped my noticed during a tired review. Signed-off-by: Chris Wilson <chris@chris-wilson.co.uk>
2011-08-09bo-rectangular: Correctly mergesort a doubly-linked listChris Wilson1-12/+13
Saves having to fixup the pointers afterwards by only having to update them on the list boundaries during merge. Signed-off-by: Chris Wilson <chris@chris-wilson.co.uk>
2011-08-09bo-rectangular: Use a mergesort to speedup insertionChris Wilson1-66/+178
However, this is only useful for inserting multiple boxes within the pixel, so we maintain the cached insert cursor as this speeds up the general case (and aides this optimisation as well). Signed-off-by: Chris Wilson <chris@chris-wilson.co.uk>
2011-08-09bo-rectangular: Eliminate allocation for pqueueChris Wilson1-178/+82
Since we only allocate a pointer to the rectangle after it is started and so decoupled from the start queue, we reuse the memory allocated for the start queue for the stop binary heap. Signed-off-by: Chris Wilson <chris@chris-wilson.co.uk>
2011-08-09fill: A horizontal/vertical line is also a degenerate fill boxChris Wilson1-13/+21
Since we discard empty fill boxes whilst filling, we can also treat horizontal/vertical lines as a filled box and so proceed with the rectangular fast path in the presence of cairo_rectangle (x, y, w, h) with w == 0 || h == 0. Signed-off-by: Chris Wilson <chris@chris-wilson.co.uk>
2011-08-09perf: Add many-fillsChris Wilson4-0/+187
A variant of many-strokes tries to answer the question of how much overhead is there in stroking, i.e. if we fill an equivalent path to a set of strokes, do we see an equivalence in performance? Signed-off-by: Chris Wilson <chris@chris-wilson.co.uk>

2011-08-08map-to-image: Handle non-32bpp formatsUli Schlachter1-6/+36
Fixes: map-all-to-image, map-bit-to-image for image16 Signed-off-by: Uli Schlachter <psychon@znc.in>
2011-08-08map_to_image: Verify the given extentsUli Schlachter1-0/+11
User shouldn't be able to use extents that are not completely inside of the surface's extents. Signed-off-by: Uli Schlachter <psychon@znc.in>
2011-08-08xlib-xcb: Fix a double free in surface_unmapUli Schlachter1-0/+4
cairo_surface_unmap_image() destroys the image that was passed to it. Since xlib-xcb calls cairo_surface_unmap_image() again for the underlying xcb surface, the surface was destroyed twice. Work around this problem by incrementing the image's reference count via cairo_surface_reference(). No idea why I didn't catch this problem when implementing these functions, I'm sure I ran the relevant tests. :-( lt-cairo-test-suite: cairo-surface.c:853: cairo_surface_destroy: Assertion `((*&(&surface->ref_count)->ref_count) > 0)' failed. Fixes: map-to-image-fill map-bit-to-image map-all-to-image Signed-off-by: Uli Schlachter <psychon@znc.in>

2011-08-08tor: Inline reverse insertion sort for handling intersectionsChris Wilson1-140/+146
The majority of intersections are with the nearest neighbour only, or within a few neighbours (in a dense intersection of lines) so if walk the active list backwards and find the new place to insert upon an intersection it is faster than performing a mergesort afterwards. Given enough intersections, the win is quite huge (15-20% on many-strokes). Signed-off-by: Chris Wilson <chris@chris-wilson.co.uk>
2011-08-07tor: First perform a bucket sort before merge the sub-edges from the polygonChris Wilson1-37/+29

2011-08-07perf: add the usual special cases to many-strokesChris Wilson1-1/+109
For completeness, also compare [aligned] horizontal and vertical strokes. Signed-off-by: Chris Wilson <chris@chris-wilson.co.uk>
2011-08-07perf: Add many-strokesChris Wilson4-0/+78
An intersection variant to exercise the stroker with many, many lines. A silly benchmark, but a popular one in the wild. Signed-off-by: Chris Wilson <chris@chris-wilson.co.uk>
2011-08-07test: Add unclosed-strokesChris Wilson4-1/+86
Checks that coincident end-points are not converted to joins. It briefly passed through my mind that was a good thing... Signed-off-by: Chris Wilson <chris@chris-wilson.co.uk>
2011-08-07test: Add a1-sampleChris Wilson4-0/+61
Ensures that only a box that covers the centre pixel is filled with antialiasing disabled. Signed-off-by: Chris Wilson <chris@chris-wilson.co.uk>
2011-08-07util: Add show-polygonsChris Wilson3-2/+568
Another variant of the utility apps that understand the output of _cairo_debug_print_polygon(). Signed-off-by: Chris Wilson <chris@chris-wilson.co.uk>
2011-08-06test: Add joins-retraceChris Wilson4-0/+111
The complexity in this shape is that the stroke is reversed upon itself and retraces the same path in the opposite direction. Signed-off-by: Chris Wilson <chris@chris-wilson.co.uk>
2011-08-06test: Add an loopy I-bar stroker testChris Wilson4-0/+102
A second relatively simple closed concave shape, all the better for debugging with. Signed-off-by: Chris Wilson <chris@chris-wilson.co.uk>
2011-08-06test: Add join-star, another stroker exerciseChris Wilson4-0/+101
A simple convex shape, useful for debugging. Signed-off-by: Chris Wilson <chris@chris-wilson.co.uk>
2011-08-05clipper: Fix crashesAndrea Canciani1-2/+1
The end of the clip path list is marked with NULL, so we should stop iterating paths when we reach it. The assertion was meant to check if paths had the same content, not if they have the same address. Fixes clip-fill-rule and clip-twice in cairo-quartz.
2011-08-05clipper: Don't emit an empty clip-path for no clip boxesChris Wilson1-0/+3
If there are no clip boxes, we do not need to emit an empty clip which only confuses the users of the surface-clipper. Spotted by Andrea Canciani and cairo-quartz Signed-off-by: Chris Wilson <chris@chris-wilson.co.uk>
2011-08-05test: Add a couple of tests to exercise stroking of short tail segmentsChris Wilson6-0/+266
Are the reference images correct? Discuss. Signed-off-by: Chris Wilson <chris@chris-wilson.co.uk>
2011-08-06subsets: use show_text_glyphs supplied utf8 to determine latin characterAdrian Johnson1-4/+29
PS files printed from PDF do not have a cmap in the subsetted fonts. If the unicode mapping has ben supplied by _show_text_glyphs we should use this instead of the reverse lookup to determine if the glyph is a latin chartacter.
2011-08-06ps: use show_text_glyphsAdrian Johnson1-12/+29
to ensure that when the PS is converted to PDF the text can be extracted.

2011-08-05test: Add world-map from the perf-suiteChris Wilson10-1/+357
As we use this a performance benchmark, it behooves us to check that we are rendering it correctly. Signed-off-by: Chris Wilson <chris@chris-wilson.co.uk>

2011-08-05bo-rectangular: handle in==out specifically for the single box caseChris Wilson1-10/+20
In this case we do not need to copy anything, but may still need to re-orientate the box. Signed-off-by: Chris Wilson <chris@chris-wilson.co.uk>
2011-08-05Mark the new API as suchNis Martensen1-0/+6
cairo_surface_create_similar_image, cairo_surface_map_to_image and cairo_surface_unmap_image were added in a69335a84eb9225b477cc8c753470eb3805b852c.
2011-08-04Clarify the API docs for the newest functionsUli Schlachter1-14/+15
Recently cairo_surface_create_similar_image(), cairo_surface_map_to_image() and cairo_surface_unmap_image() were introduced. However, the documentation was slightly misleading and recommended a wrong usage. Signed-off-by: Uli Schlachter <psychon@znc.in>
2011-08-04perf: Also build the code in perf/microUli Schlachter1-0/+2
This fixes weird and occasional build failures when updating the source, e.g.: cairo-perf-micro.o:(.rodata+0xb0): undefined reference to `hash_table' Signed-off-by: Uli Schlachter <psychon@znc.in>
2011-08-04xlib-xcb: Implement the new backend functionsUli Schlachter1-3/+38
This implements create_similar_image, map_to_image and unmap. Signed-off-by: Uli Schlachter <psychon@znc.in>
2011-08-04surface_unmap_image: Fix fallbackUli Schlachter1-1/+18
The fallback code assumed that the caller mapped the complete surface to an image. If only parts of a surface were mapped, the code didn't correctly translate and clip its operations. Fixes map-bit-to-image for xlib-xcb and improves the result for recording. Thanks to Chris Wilson for some simplifications. Signed-off-by: Uli Schlachter <psychon@znc.in>
2011-08-04ps: check if images are grayscale or monochrome and encode as suchAdrian Johnson1-52/+110
Printing PDFs with large monochrome or grayscale images would result in the images being blown up to 24-bit color images. Some printers are very slow to print huge color images.
