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. Among the -issues are - -- inconsistent naming style (fb vs Fb, camelCase vs - underscore_naming). Sometimes there is even inconsistency *within* - one name. - - fetchProc32 ACCESS(pixman_fetchProcForPicture32) - - may be one of the uglies names ever created. - - coding style: - use the one from cairo except that pixman uses this brace style: - - while (blah) - { - } - - Format do while like this: - - do - { - - } - while (...); - -- PIXMAN_COMPOSITE_RECT_GENERAL() is horribly complex - -- switch case logic in pixman-access.c - - Instead it would be better to just store function pointers in the - image objects themselves, - - get_pixel() - get_scanline() - -- Much of the scanline fetching code is for formats that no one - ever uses. a2r2g2b2 anyone? - - It would probably be worthwhile having a generic fetcher for any - pixman format whatsoever. - -- Code related to particular image types should be split into individual - files. - - pixman-bits-image.c - pixman-linear-gradient-image.c - pixman-radial-gradient-image.c - pixman-solid-image.c - -- Fast path code should be split into files based on architecture: - - pixman-mmx-fastpath.c - pixman-sse2-fastpath.c - pixman-c-fastpath.c - - etc. - - Each of these files should then export a fastpath table, which would - be declared in pixman-private.h. 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/gfx/cairo/libpixman/src/solaris-hwcap.mapfile b/gfx/cairo/libpixman/src/solaris-hwcap.mapfile new file mode 100644 index 0000000000..87efce1e34 --- /dev/null +++ b/gfx/cairo/libpixman/src/solaris-hwcap.mapfile @@ -0,0 +1,30 @@ +############################################################################### +# +# Copyright 2009, Oracle and/or its affiliates.
