This post-processing increased the contrast of scaled-down features - mainly lines and fonts, relative to the background. The effect does not improved readability and in some cases makes the scaled-down version look like a different document at a glance. Text that is normal weight appears bold when scaled down in these cases.

2017-10-26Consistently apply JS size checkRyan Harrison
This CL makes the use of CXFA_IsTooBig consistent and universal across all of the ToJavascript and related methods. Previously this method was only applied in some calls. It is now being tested as a precondition and postcondition on every call and as a post condition for the entire translation process. There are some size checks within methods that potentially generate large amounts of JS that have been left in.

2017-10-25Enforce end of data in CJBig2_ArithDecoderNicolas Pena
Quoting the JBIG2 spec: "If B is a 0xFF byte, then B1 (the byte pointed to by BP+1) is tested. If B1 exceeds 0x8F, then B1 must be one of the marker codes. The marker code is interpreted as required, and the buffer pointer remains pointed to the 0xFF prefix of the marker code which terminates the arithmetically compressed data. 1-bits are then fed to the decoder until the decoding is complete. This is shown by adding 0xFF00 to the C-register and setting the bit counter CT to 8." Our implementation is the alternative (faster for software according to the spec), where only CT is changed to 8. Reaching this part of the code means we will never read from stream again so we should be wrapping up the decoding. To ensure this, the |m_Complete| attribute is set to true if we reach this code again, which will result in bailing out next time DECODE is called.

2017-10-25Add in depth check for ToJavascript and related methodsRyan Harrison
There exists a similar check for the parser, but it doesn't catch all cases of excessive memory usage, since a single parse step can generate multiple expressions that need to be converted or other cases where the parse depth doesn't match the emission depth later. Due to the expressions appearing in two different inheritence hierachies the depth information needs to be stored outside of the classes, thus the new depth class. Another way to handle this would be to change the method calls to take in a visitor object that tracks depth. This would require significant reworking of some of the code, so I am going to file a bug about doing that conversion as a cleanup.
