relrelb 3d8779b377 swf: Ignore length mismatch in `read_action` 
Flash continues in such case, so just warn instead of failing.
 2021-08-03 14:40:59 -07:00
relrelb 04af276ecb swf: Extract `Opcode::format` and `TagCode::format` 2021-08-03 14:40:59 -07:00

David Wendt 7dc86fdeb0 swf: Throw an error if an ABC bitstream calls for a parameter with more optional parameters than actual ones. 2021-07-20 22:10:30 -04:00
David Wendt 4122c1b96e swf: Default method parameters are indexed starting from the first optional parameter, not from zero. 2021-07-20 22:05:29 -04:00
relrelb d2eb46d3be chore: Reserve capacity for vectors 
This avoids unnecessary re-allocations and thus should improve
performance in both memory and time terms.

relrelb 5dde3ecabf swf: Optimize `read_f64_me` and `write_f64_me` 
Each function is reduced to just 3 opcodes on x86:
https://godbolt.org/z/n6q6zxnh6

WebAssembly benefits as well: https://godbolt.org/z/fcETE9GYn

This should improve load-time performance because read_f64_me is
used frequently (for each AVM1 double constant).

relrelb c2378416a9 tests: Simplify `read_tag_bytes_from_file_with_index` 
Let the `Reader` outlive outside the loop, so it tracks its own
position, instead of doing so manually.
Also move `read_from_file` outside and reuse it.
 2021-07-12 23:09:29 +03:00
relrelb 99deb90a1f swf: Avoid using `Reader::input` directly 
Change two cases to use `Reader::read_slice` instead of `self.input`.
Not only this avoids relying on an implementation detail, this also
raises an `UnexpectedEof` error if the read is beyond the SWF.

relrelb ef9c073d26 swf: General cleanup 
Just mechanical cleanups to ease future refactors.
 2021-07-12 23:09:29 +03:00
relrelb 9e18e32b40 swf: Fix read_i24 
Only the third byte should be cast to i8 in order to sign extend correctly.

It was writing in the wrong endian.

Mike Welsh d23ea90459 swf: Change Matrix to use Fixed16 for a, b, c, d 
Matrices in an SWF file store their scale/skew components in
in 16.16 format (fbits).

Split `ruffle_core::Matrix` and `swf::Matrix`. `swf::Matrix` now
stores its data as `Fixed16` instead of immediately converting to
`f32`.

Mike Welsh 0552d26551 core: Use Fixed8 and i16 for ColorTransform 
Use the proper types for ColorTransform:
 * Fixed8 (8.8) format for multiplicative component
 * i16 format for additive component

This matches the behavior of Flash (for example, alpha only changes
in units of 1/256).
