2015-03-19Fix subtle issues in opj_skip_from_memory and add unit tests.Tom Sepez
Follow on to https://codereview.chromium.org/990683002/. This more closely mimics what fseek() actually does, so as to avoid subtle bugs down the road. Move the DecodeData struct into a header so the test can use it, and provide a constructor for it. Along the way, I added include guards, removed the p_ prefix from some non-pointer vars, fixed some IWYU, and resolved some signed/unsigned comparison warnings with careful casting.

2015-03-16Fix a bug that JPX images can't be shownJUN FANG
In the process of opj_end_decompress, it will return fail when the end of coding stream is reached. However it returns true in the same scenario implemented in openJPEG. So the final solution is from openJPEG. Return true when the end of coding stream is reached. BUG=452671 R=tsepez@chromium.org Review URL: https://codereview.chromium.org/990683002

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.
