Mike Welsh 58642d0e0e tests: Add swf tests for DefineMorphShape gradient flags 2019-10-10 21:52:41 -07:00
Mike Welsh 1b7449e651 swf: Fix reading DefineMorphShape gradient flags 
The interpolation and spread modes of morph shape gradients were
not being properly parsed. Fixed this and cleaned up some of the
gradient parsing code.

Mike Welsh bb4b931610 swf: Allow for missing latency seek value in SoundStreamHead 
Some software would export SWFs with a missing LatencySeek field
in SoundStreamHead (e.g., CoffeeCup Firestarter). Silently ignore
this error if the field is missing.

Mike Welsh 614903bdec swf: Remove panic when data left over in tag 2019-10-10 21:52:41 -07:00
Mike Welsh 800147043a swf: Try to recover from incorrect zlib streams 
Some SWFs are compressed incorrectly, often with incorrect
compressed/uncompressed lengths, causing the zlib decoders
to vomit if you try to decompress them fully. However, often times
the data still decompresses all the way to the End tag, and we
still want to try to play it even if it's corrupt.
Now these errors only omit a warning, and we'll continue to run
the SWF.

Addresses #86.

Mike Welsh 93a221aea4 swf: Add tests for errors on incorrect parse 2019-10-10 00:55:09 -07:00
Mike Welsh 3058b88011 swf: Add custom error type for SWF/AVM1 parse errors 
Improves the error handling for the swf crate:

 * Custom swf::error::Error type added to handle various errors
   in SWF parsing.
 * Invalid parsing of tags/AVM1 ops results in a Error::ParseError
   that can include info about the underlying failure.
 * Implement Display for these errors. Output descriptive
   names for the tag/opcode when it fails to parse.
 * Handle out of bounds reads in avm1::Reader::read_slice.
   Previously this would panic, now it returns an io::Error.

Closes #85.

Mike Welsh 0506b7c566 web: Calculate bounds for text glyphs when not present 
The text bounds fields for a DefineFont2/3 tag can be a bogus empty
rectangle, per the SWF spec. We must properly the bounds ourselves
to render properly on web.

Mike Welsh eded29ce6d text: Add dummy implementation of device text 
Embed an SWF version of Noto Sans (core/assets/*) into the player.
The player will load this font and use it to render device text.

This is a quicky implementation to get dynamic device text
rendering.

David Wendt 2d365856a7 Fix tellTarget being broken by the introduction of scopes. We now create a new scope chain based off the selected active clip. 2019-10-06 13:02:31 -07:00
David Wendt 588b2bb061 Fixes to make tests compile again 2019-10-06 13:02:31 -07:00
David Wendt 5873eefb06 Since it is possible to have virtual properties in the scope chain, overwriting them should trigger their setters. 
Define, since it's intended for setting locals only, always uses force-set and does not trigger setters.
