15// This test exercises the Matrix/Clip State collapsing system. It generates
16// example skps and the compares the actual stored operations to the expected
17// operations. The test works by emitting canvas operations at three levels:
18// overall structure, bodies that draw something and model/clip state changes.
19//
20// Structure methods only directly emit save and restores but call the
21// ModelClip and Body helper methods to fill in the structure. Since they only
22// emit saves and restores the operations emitted by the structure methods will
commit-bot@chromium.org5e0995e2014-02-07 12:20:04 +000023// be completely removed by the matrix/clip collapse. Note: every save in
robertphillips@google.com1f718462014-02-06 14:22:47 +000024// a structure method is followed by a call to a ModelClip helper.
25//
26// Body methods only directly emit draw ops and saveLayer/restore pairs but call
27// the ModelClip helper methods. Since the body methods emit the ops that cannot
28// be collapsed (i.e., draw ops, saveLayer/restore) they also generate the
29// expected result information. Note: every saveLayer in a body method is
30// followed by a call to a ModelClip helper.
31//
32// The ModelClip methods output matrix and clip ops in various orders and
commit-bot@chromium.org5e0995e2014-02-07 12:20:04 +000033// combinations. They contribute to the expected result by outputting the
robertphillips@google.com1f718462014-02-06 14:22:47 +000034// expected matrix & clip ops. Note that, currently, the entire clip stack
35// is output for each MC state so the clip operations accumulate down the
36// save/restore stack.
37
38// TODOs:
39// check on clip offsets
40// - not sure if this is possible. The desire is to verify that the clip
41// operations' offsets point to the correct follow-on operations. This
42// could be difficult since there is no good way to communicate the
43// offset stored in the SkPicture to the debugger's clip objects
commit-bot@chromium.org5e0995e2014-02-07 12:20:04 +000044// add comparison of rendered before & after images?
robertphillips@google.com1f718462014-02-06 14:22:47 +000045// - not sure if this would be useful since it somewhat duplicates the
46// correctness test of running render_pictures in record mode and
47// rendering before and after images. Additionally the matrix/clip collapse
48// is sure to cause some small differences so an automated test might
49// yield too many false positives.
50// run the matrix/clip collapse system on the 10K skp set
51// - this should give us warm fuzzies that the matrix clip collapse
52// system is ready for prime time
53// bench the recording times with/without matrix/clip collapsing
