c# - Why does ImageResizer not handle extraction of tiff pages if the tiff has pages of differing image types? -

-

i'm using imageresizer.net in console app pull pages out of tiff images, when tiff contains pages of differing image types, imageresizer extracts not represent original page.

i using managed api, code: imagebuilder.current.build(sourceimagepath, destinationimagepath, new resizesettings("page=[whatever]"));

the tiff image contains...

  • page 1, image type "bilevel (white zero)", compression "group 3", size "485kb".
  • page 2, image type "ycbcr (2,1 subsampling)", compression "jpeg (old style)", size "11mb".
  • page 3, image type "ycbcr (2,1 subsampling)", compression "jpeg (old style)", size "11mb".
  • page 4, image type "grayscale (256 grays, black zero)", compression "jpeg (old style)", size "4mb".

the behaviour getting is...

  • extracting page 1 works correctly.
  • extracting page 2 ends extracting image of page 1.
  • extracting page 3 ends extracting image of page 1, squashed band 1cm wide on left hand side of image, remaining image black.
  • extracting page 4 works correctly.

i have used libtiff.net extract same images using this method, not exhibit same fault.

edit - using code test wic decoder:

var settings = new resizesettings("decoder=wic&page=" + pagenumber); config.current.plugins.getorinstall<wicdecoderplugin>(); imagebuilder.current.build(sourceimagepath, destimagepath, settings);

this works page 1 & 4 (no change there), 'object reference not set instance of object.' error page 2 & 3 when using wic decoder.

edit 2 - converted bit that's failing mvc project /resizer.debug:

update 12/12/2012:

the freeimagedecoder plugin supports multi-page tiff files, , uses libtiff internally. suggested way deal complex/rare .tiff files.

the tiff format extremely complex , poorly standardized. libraries (like gdi+ (system.drawing) , wic (wpf)) implement fraction of standard, let alone de-facto features , additions.

to level of .tiff support, need use library dedicated .tiff support such libtiff or libtiff.net.

imageresizer does integrate libtiff via freeimage , freeimagedecoder plugin, multi-page support hasn't been implemented yet.

you're not creek without paddle - there many ways solve dilemma:

  1. fork freeimagedecoder , add multi-page support. difficulty: 7
  2. subclass builderextension, override decodestream, , glue in libtiff.net. difficulty: 5
  3. subclass builderextension, override decodestream, , glue in libtiff. difficulty: 10
  4. post idea on uservoice site , 30 votes. difficulty:?
  5. pay me it. difficulty: 3 (my next available slot several months now, however).

there 4 example implementations of decoders: imagebuilder.decodestream, psdreader, wicdecoder, freeimagedeocoder, , pdfrenderer. source code them is included in download. average decoder requires less 80 lines of code.

c++ - Using OpenSSL in a multi-threaded application -

i have been writing soap client application in c++ on ubuntu using openssl https transport , pthreads threading. have number of threads - 1 central data acquisition thread periodically gets worker threads make soap requests via shared mutex protected queues. reading documentation openssl found is openssl thread-safe? in openssl faq describes mechanisms required ensure thread safety when using openssl. implemented , works fine. the reason question conceptual difficulty really. thinking implementing same functionality application has already, instead of using threads, create 2 seperate applications : 1 worker thread (of multiple copies running) , main data acquisition thread. use tcp sockets communicate between 2 rather mutex protected queues. may bad idea not important - confusing me would have implement same functions required ensure openssl thread safety in second approach or not? my guess not have , treated independent (indeed surely must many applications use openssl) re...

All overlapping substrings matching a java regex -

-
is there api method returns (possibly overlapping) substrings match regular expression? for example, have text string: string t = 04/31 412-555-1235; , , have pattern: pattern p = new pattern("\\d\\d+"); matches strings of 2 or more characters. the matches are: 04, 31, 412, 555, 1235. how overlapping matches? i want code return: 04, 31, 41, 412, 12, 55, 555, 55, 12, 123, 1235, 23, 235, 35. theoretically should possible -- there obvious o(n^2) algorithm enumerates , checks substrings against pattern. edit rather enumerating substrings, safer use region(int start, int end) method in matcher . checking pattern against separate, extracted substring might change result of match (e.g. if there non-capturing group or word boundary check @ start/end of pattern). edit 2 actually, it's unclear whether region() expect zero-width matches. specification vague, , experiments yield disappointing results. for example: string line = "xx90xx"; strin...
