chore: Migrate from enumset to bitflags 2021-01-21 16:35:46 -08:00
Mike Welsh 2254589e71 swf: Don't error on focal gradients in DefineShape tags (fix #2730) 2021-01-21 15:47:04 -08:00
Mike Welsh 66256dd3be swf: SwfStr no longer contains encoding 
SwfStr is now an unsized slice analogous to `str` or `bstr`.
The desired encoding must be supplied when converting to String.

Mike Welsh 7cf217a911 swf: Use lzma-rs for LZMA SWFs (fix #405) 
Pure Rust decoder that functions on desktop and wasm.
Enable lzma feature by default.

TODO: Switch to lzma-rs streaming API when stable on crates.io.
Currently decodes entire stream at once.

Mike Welsh cec0ca74e1 chore: Fix swf doctests working directory 
Rust 12-09 nightly changed the working dir of doctests to be the
workspace root instead of the subcrate root. This broke the
doctests for swf. Now do some setup to ensure the same working
directory on both stable and nightly.

Mike Welsh 0c38dafd0d avm1: Switch to SmallVec for ActionPush 
While switching swf to return slices, I noticed ActionPush was
potentially allocating a huge vector by mistake.
Switch to SmallVec<[Value; 4]> to fix this and avoid the
allocation in general (this was fairly high up in the profiler).

TODO: Return an iterator instead of any sort of vec.

Mike Welsh 4467ccf7e3 tests: Add swf test for bitmap line style 2020-10-10 16:35:37 -07:00
Mike Welsh ed99a15dee swf: Fill styles are byte aligned 
A bitmap fill style ends in a matrix, but the overall type should
still be byte aligned. This could cause certain shapes with bitmap
line styles to be incorrectly parsed. Fixes #1192.

Mike Welsh 5ea06b0ce6 swf: Use Option for more PlaceObject parameters

and none (don't modify), so make this explicit for some PlaceObject

Fixes #1104.

Mike Welsh d7a186b2cd avm1: Implement shape hit testing 2020-09-02 17:51:55 -07:00
David Wendt 345a244ed4 `read_i32` no longer panics if more than 28 bits are defined within the read-in integer constant. 
The underlying problem is actually shift overflow - on the fifth byte in the sequence, it attempts to mask bits by shifting them off the left of the value, which doesn't work here, as we'll be shifting by -3. For those unaware, shifting by a negative does NOT shift in the opposite direction, it instead gives your C compiler permission to stuff demons up your nose.

I wouldn't be surprised if this is just outright UB in Flash Player.

Mike Welsh 4680b01f03 swf: Allow StyleChangeRecord in DefineShape v1 
The spec says that StyleChangeRecord is only supported in
DefineShape2+, but SWFs exist with StyleChangeRecord in
DefineShape1 tags, and these play correctly in the Flash Player.
