It is also worth -considering a generic format based pixel fetcher for these edge cases. - -Since the actual routines depend on the image attributes, the images -must be notified when those change and update their function pointers -appropriately. So there should probably be a virtual function called -(* reinit) or something like that. - -There will also be wide fetchers for both pixels and lines. The line -fetcher will just call the wide pixel fetcher. The wide pixel fetcher -will just call expand, except for 10 bit formats. - -Rendering pipeline: - -Drawable: - 0. if (picture has alpha map) - 0.1. Position alpha map according to the alpha_x/alpha_y - 0.2. Where the two drawables intersect, the alpha channel - Replace the alpha channel of source with the one - from the alpha map. Replacement only takes place - in the intersection of the two drawables' geometries. - 1. Repeat the drawable according to the repeat attribute - 2. Reconstruct a continuous image according to the filter - 3. Transform according to the transform attribute - 4. Position image such that src_x, src_y is over dst_x, dst_y - 5. Sample once per destination pixel - 6. Clip. If a pixel is not within the source clip, then no - compositing takes place at that pixel. (Ie., it's *not* - treated as 0). - - Sampling a drawable: - - - If the channel does not have an alpha channel, the pixels in it - are treated as opaque. - - Note on reconstruction: - - - The top left pixel has coordinates (0.5, 0.5) and pixels are - spaced 1 apart. - -Gradient: - 1. Unless gradient type is conical, repeat the underlying (0, 1) - gradient according to the repeat attribute - 2. Integrate the gradient across the plane according to type. - 3. Transform according to transform attribute - 4. Position gradient - 5. Sample once per destination pixel. - 6. Clip - -Solid Fill: - 1. Repeat has no effect - 2. Image is already continuous and defined for the entire plane - 3. Transform has no effect - 4. Positioning has no effect - 5. Sample once per destination pixel. - 6. Clip - -Polygon: - 1. Repeat has no effect - 2. Image is already continuous and defined on the whole plane - 3. Transform according to transform attribute - 4. Position image - 5. Supersample 15x17 per destination pixel. - 6. Clip - -Possibly interesting additions: - - More general transformations, such as warping, or general - shading. - - - Shader image where a function is called to generate the - pixel (ie., uploading assembly code). - - - Resampling kernels - - In principle the polygon image uses a 15x17 box filter for - resampling. If we allow general resampling filters, then we - get all the various antialiasing types for free. - - Bilinear downsampling looks terrible and could be much - improved by a resampling filter. NEAREST reconstruction - combined with a box resampling filter is what GdkPixbuf - does, I believe. - - Useful for high frequency gradients as well. - - (Note that the difference between a reconstruction and a - resampling filter is mainly where in the pipeline they - occur. High quality resampling should use a correctly - oriented kernel so it should happen after transformation. - - An implementation can transform the resampling kernel and - convolve it with the reconstruction if it so desires, but it - will need to deal with the fact that the resampling kernel - will not necessarily be pixel aligned. - - "Output kernels" - - One could imagine doing the resampling after compositing, - ie., for each destination pixel sample each source image 16 - times, then composite those subpixels individually, then - finally apply a kernel. - - However, this is effectively the same as full screen - antialiasing, which is a simpler way to think about it. So - resampling kernels may make sense for individual images, but - not as a post-compositing step. - - Fullscreen AA is inefficient without chained compositing - though. Consider an (image scaled up to oversample size IN - some polygon) scaled down to screen size. With the current - implementation, there will be a huge temporary. With chained - compositing, the whole thing ends up being equivalent to the - output kernel from above. - - - Color space conversion - - The complete model here is that each surface has a color - space associated with it and that the compositing operation - also has one associated with it. Note also that gradients - should have associcated colorspaces. - - - Dithering - - If people dither something that is already dithered, it will - look terrible, but don't do that, then. (Dithering happens - after resampling if at all - what is the relationship - with color spaces? Presumably dithering should happen in linear - intensity space). - - - Floating point surfaces, 16, 32 and possibly 64 bit per - channel. - - Maybe crack: - - - Glyph polygons - - If glyphs could be given as polygons, they could be - positioned and rasterized more accurately. The glyph - structure would need subpixel positioning though. - - - Luminance vs. coverage for the alpha channel - - Whether the alpha channel should be interpreted as luminance - modulation or as coverage (intensity modulation). This is a - bit of a departure from the rendering model though. It could - also be considered whether it should be possible to have - both channels in the same drawable. - - - Alternative for component alpha - - - Set component-alpha on the output image. - - - This means each of the components are sampled - independently and composited in the corresponding - channel only. - - - Have 3 x oversampled mask - - - Scale it down by 3 horizontally, with [ 1/3, 1/3, 1/3 ] - resampling filter. - - Is this equivalent to just using a component alpha mask? - - Incompatible changes: - - - Gradients could be specified with premultiplied colors. (You - can use a mask to get things like gradients from solid red to - transparent red. - -Refactoring pixman - -The pixman code is not particularly nice to put it mildly.

This should allow us to get rid - of the pixman-mmx.h files. - - The fast path table should describe each fast path. Ie there should - be bitfields indicating what things the fast path can handle, rather than - like now where it is only allowed to take one format per src/mask/dest. Ie., - - { - FAST_a8r8g8b8 | FAST_x8r8g8b8, - FAST_null, - FAST_x8r8g8b8, - FAST_repeat_normal | FAST_repeat_none, - the_fast_path - } - -There should then be *one* file that implements pixman_image_composite(). -This should do this: - - optimize_operator(); - - convert 1x1 repeat to solid (actually this should be done at - image creation time). - - is there a useful fastpath? - -There should be a file called pixman-cpu.c that contains all the -architecture specific stuff to detect what CPU features we have. - -Issues that must be kept in mind: - - - we need accessor code to be preserved - - - maybe there should be a "store_scanline" too? - - Is this sufficient? - - We should preserve the optimization where the - compositing happens directly in the destination - whenever possible. - - - It should be possible to create GPU samplers from the - images. - -The "horizontal" classification should be a bit in the image, the -"vertical" classification should just happen inside the gradient -file. Note though that - - (a) these will change if the tranformation/repeat changes. - - (b) at the moment the optimization for linear gradients - takes the source rectangle into account. Presumably - this is to also optimize the case where the gradient - is close enough to horizontal? - -Who is responsible for repeats? In principle it should be the scanline -fetch. Right now NORMAL repeats are handled by walk_composite_region() -while other repeats are handled by the scanline code. - - -(Random note on filtering: do you filter before or after -transformation? Hardware is going to filter after transformation; -this is also what pixman does currently). It's not completely clear -what filtering *after* transformation means. One thing that might look -good would be to do *supersampling*, ie., compute multiple subpixels -per destination pixel, then average them together. diff --git a/pixman/test/blitters-test.c b/pixman/test/blitters-test.c index 8766fa800..a2c6ff4d8 100644 --- a/pixman/test/blitters-test.c +++ b/pixman/test/blitters-test.c @@ -46,7 +46,16 @@ create_random_image (pixman_format_code_t *allowed_formats, /* do the allocation */ buf = aligned_malloc (64, stride * height); - prng_randmemset (buf, stride * height, RANDMEMSET_MORE_00_AND_FF); + if (prng_rand_n (4) == 0) + { + /* uniform distribution */ + prng_randmemset (buf, stride * height, 0); + } + else + { + /* significantly increased probability for 0x00 and 0xFF */ + prng_randmemset (buf, stride * height, RANDMEMSET_MORE_00_AND_FF); + } img = pixman_image_create_bits (fmt, width, height, buf, stride); @@ -393,6 +402,6 @@ main (int argc, const char *argv[]) } return fuzzer_test_main("blitters", 2000000, - 0xD8265D5E, + 0x0CF3283B, test_composite, argc, argv); } diff --git a/pixman/test/lowlevel-blt-bench.c b/pixman/test/lowlevel-blt-bench.c index 4e16f7ba1..1049e21e7 100644 --- a/pixman/test/lowlevel-blt-bench.c +++ b/pixman/test/lowlevel-blt-bench.c @@ -385,6 +385,7 @@ bench_composite (char * testname, double t1, t2, t3, pix_cnt; int64_t n, l1test_width, nlines; double bytes_per_pix = 0; + pixman_bool_t bench_pixbuf = FALSE; pixman_composite_func_t func = pixman_image_composite_wrapper; @@ -422,16 +423,20 @@ bench_composite (char * testname, mask_img = NULL; xmask_img = NULL; + if (strcmp (testname, "pixbuf") == 0 || strcmp (testname, "rpixbuf") == 0) + { + bench_pixbuf = TRUE; + } if (!(mask_flags & SOLID_FLAG) && mask_fmt != PIXMAN_null) { bytes_per_pix += (mask_fmt >> 24) / ((op == PIXMAN_OP_SRC) ?
