2013-06-20Rearrange source files.Tor Andersson
2013-06-18Merge common and internal headers into one.Tor Andersson
2013-06-18Move header files into separate include directory.Tor Andersson
2012-09-21Move defaulting of image params into predictor function.Robin Watts
This makes no difference to the current operation of the code, but ensures that 'saner' values are put into the image_params structure. This will help pdfwrite give more aesthetically pleasing output later.
2012-07-05Move to static inline functions from macros.Robin Watts
Instead of using macros for min/max/abs/clamp, we move to using inline functions. These are more typesafe, and should produce equivalent code on compilers that support inline (i.e. pretty much everything we care about these days). People can always do their own macro versions if they prefer.
2012-07-04Prediction filter assumes it's writing to zeroed memory.Robin Watts
The putcomponent function assumes the function has been cleared. Simple fix to clear bytes at the start of each scanline. Problem seen with normal_217.pdf
2012-06-28Update tiff iamge predictor to cope with 16 bits.Robin Watts
normal_178.pdf contains a monochrome black and white image, encoded as 16bpc rgb.
2012-03-06Split fitz.h/mupdf.h into internal/external headers.Robin Watts
Attempt to separate public API from internal functions.
2012-02-03Remove extraneous blank lines.Tor Andersson
2012-01-27Remove dependency on fz_obj from the filter creation parameters.Tor Andersson
2011-12-17More memsqueezing fixes; stream creation.Robin Watts
2011-12-17Change stream 'close' functions to facilitate error cleanup.Robin Watts
Rather than passing a stream to a close function, just pass context and state - that's all that is required. This enables us to call close to cleanup neatly if the stream fails to allocate.
2011-12-16Add fz_malloc_struct, and make code use it.Robin Watts
The new fz_malloc_struct(A,B) macro allocates sizeof(B) bytes using fz_malloc, and then passes the resultant pointer to Memento_label to label it with "B". This costs nothing in non-memento builds, but gives much nicer listings of leaked blocks when memento is enabled.
2011-12-08Throw exceptions for read errors.Tor Andersson
2011-09-21Add warning context.Tor Andersson
2011-09-21Don't thread ctx through safe fz_obj functions.Tor Andersson
2011-09-15Add context to mupdf.Robin Watts
Huge pervasive change to lots of files, adding a context for exception handling and allocation. In time we'll move more statics into there. Also fix some for(i = 0; i < function(...); i++) calls.
2011-09-14Initial import of exception handling codeRobin Watts
Import exception handling code from WSS, modified to fit into the fitz world. With this code we have 'real' fz_try/fz_catch/fz_rethrow functions, handling a fz_except type. We therefore rename the existing fz_throw/ fz_catch/fz_rethrow to be fz_error_make/fz_error_handle/fz_error_note. We don't actually use fz_try/fz_catch/fz_rethrow yet...
2011-04-08Remove inline keyword where it is not strictly necessary for performance.Tor Andersson
Also put the function on the same line for inline functions, so they stick out and are easy to find with grep.
2011-04-04Le Roi est mort, vive le Roi!Tor Andersson
The run-together words are dead! Long live the underscores! The postscript inspired naming convention of using all run-together words has served us well, but it is now time for more readable code. In this commit I have also added the sed script, rename.sed, that I used to convert the source. Use it on your patches and application code.
2010-08-02Use 'while (rp < wp)' idiom for filter output buffering state.Tor Andersson
2010-07-29Use chained reader like interface for filters instead of process interface.Tor Andersson
2010-07-23Fix typo in grayscale image sampling.Tor Andersson
2010-07-23Make predictor filter flush partially processed scanlines when encountering ↵Sebastian Rasmussen
EOF in input.
2010-07-20Replace explicit comparisons with MIN/MAX/ABS macros.Sebastian Rasmussen
2010-07-17Remove all trailing whitespace.Tor Andersson
2010-06-29Reformat to remove all instances of double spaces (to easier spot ↵Tor Andersson
indentation errors in the future).
2010-06-29Move over to RGBA instead of ARGB. Add missing gray-alpha 'duff' functions.Robin Watts
2010-06-18Prediction filter optimisations: avoid needless copying and switch then for, ↵Robin Watts
not for then switch.
2009-12-03Consolidate include lines to a single fitz.h.Tor Andersson
2009-11-29Add some braces and fix up double-indentation on multi-line if/while ↵Tor Andersson
expressions.
2009-11-29Fix up indentation.Tor Andersson
2009-11-20Malloc cannot return null. Clean up streams and filters.Tor Andersson
2009-11-19Remove unused and largely untested encoding filters.Tor Andersson
2009-06-22Handle invalid predictors properly.Sebastian Rasmussen
2009-03-11Remove fz_outofmem constant.Tor Andersson
2009-03-11Change fz_error* struct into an integer error type fz_error.Tor Andersson
