2018-05-22Fix method style in JBig2_Image.Lei Zhang
Rename fooBar() to FooBar(). Change-Id: I87775fa14ce7e4f4a5897780d0d02fb61c7693ff Reviewed-on: https://pdfium-review.googlesource.com/32739 Commit-Queue: Ryan Harrison <rharrison@chromium.org> Reviewed-by: Ryan Harrison <rharrison@chromium.org>
2018-05-17Expose CJBig2_Image::ComposeTo() as a public method.Lei Zhang
CJBig2_Image::ComposeFrom() wraps a call to ComposeTo() and does an extra validity check. In tight loops where the validity check will always succeed, this is wasteful. Change existing callers of ComposeFrom() to ComposeTo() when the validity check has already been done.

Instead of allocating an N-pixel array to store some temporary values, just use a single integer.

2018-05-01Add struct CJBig2_GRDProc::ProgressiveArithDecodeState.Lei Zhang
Track the decode state in one data structure. Also grab pointers to data structure members before tight loops when decoding. It turns out referring to this->foo in tight loops can actually slow down decoding.
