2014-09-02Tidy up opj_ callback functions in fx_codec_jpx_obj.cppTom Sepez
This is code cleanup rather than bug fixing. The motivation for this was to fix the casts at line 97 of the original file. These are wrong; you cannot correct via casting a function signature mismatch when passing a function as an argument. In theory, there's no reason to believe that the compiler will pass args in the same manner for a function of type (void*, size_t, void*) as for a function of type (void*, size_t, some_struct*). The cast will suppress the compile error, but you can't be assured the call will work as intended. In practice, it does, since the last architecture where a void* had a different representation than a struct* went extinct in the late 80s. In the functions themselves, note that we currently bail out if srcData->offset >= srcData->src_size, so the expression bufferLength = (OPJ_SIZE_T)(srcData->src_size - srcData->offset) will always be > 0. Hence the check if(bufferLength <= 0) is pointless, esp. since bufferLength is a signed type and < 0 makes no sense. The opj_seek_from_memory() has a bool return value, so returning -1 on error doesn't seem reasonable. Change this to TRUE/FALSE, and return false on seek past end. If we're truly passing readonly data, then perhaps it makes sense to make the write() function always return -1. I didn't do this. Lastly, I capitalize "DecodeData" so that it looks like a struct, and change its members to be size_t's to avoid casting back and forth.

2014-08-31Remove the GetValidBpc check in application callers and move it to where ↵Bo Xu
m_bpc is assigned. The problem of using GetValidBpc() in each function call is it could result in mismatch as seen in this case: in ContinueToLoadMask(), m_bpc is re-assigned to 1 if m_bImageMask==1 regardless of the value from GetValidBpc(). This will result in mismatch if another function use the value from GetValidBpc(). The solution could be checking m_bImageMask in another function to make sure m_bpc is consistent, but that makes the code too cumbersome. Also, we have to bring and are bringing in more and more GetValidBpc check, and this will continue with other buggy documents. So better to fix it now. The original rational to use GetValidBpc() in where m_bpc is used is to respect the "raw" data from parsing. However, if it will be ignored anyway and using value from GetValidBpc(), we'd better correct it at the very beginning.
