  • suggestion 3/3: automatic plots per label

    Suppose you have a big datafile with lines formatted as: label ; x ; y And you wish to output one plot per label. Could gnuplot handle this automatically, i.e. upon reading a new "label" string value, start a new plot ? (e.g. set plotfamily field 1) Otherwise, one has to split the consolidated file into many datafiles (one per label value) and instruct gnuplot to draw them...

  • suggestion 2/3: x-range collapse

    In some applications, typically where time extends over long periods and events occur over shorter periods (e.g. a few hours over 24 hours), there are big gaps with no data. It would be quite interesting to introduce a new directive, shrinking big gaps to discontinuity points. So i suggest to introduce the directive: # set xcollapse 3600 10 which tells here that x-ranges greater than...

  • suggestion 1/3: control over curve continuity

    This post introduces a series of 3 suggestions of new features for the amazing GNUPLOT program ! So feature #1 is providing control over curve continuity. We have a directive which specifies: set datafile missing '?' It would be nice to allow curves either to break at missing points, or simply pass through (continuous if style is "lines","linespoints"...). I suggest...

  • multipage PDF

    Hallo, Most of the code from bmeps, i guess, is dedicated to hanling formats and bytestreams (coding) - the hard and heavy part ... On the other hand, PDF syntax for multipage is rather simple (as far as the structure of the page is simple, e.g. here one single object/image embedded). This must have been already suggested, but would it complex to extend bmeps so that it could generate...

  • image formats than can be embedded in PDF ?

    Hallo ! Does PDF support "pure" embedded PNG images ? In most PDF files i have come across, JPEG images are often stored "as is" in objects, and by they can be extracted without loss be merely copying bytes from the PDF object. Can this also be done with PNG images ? (there is an instruction called /Filter/FlateDecode but i have never see a string...

  • Followup: RE: TOC: compatibility/OS, performance

    Thanks for tour answer -- and providing us a wonderful tool by the way :-) I am planning to write a filesystem driver for mounting 7z archives (it seems there is no such tool available so far -- is someone aware of any ?) The information about the TOC structure itself is indeed well documented ! But i definitely cannot decode a TOC using LMZA.EXE (from the SDK). I have tried to feed...

  • TOC: compatibility/OS, performance

    Hello, I presume 7zip archives are compatible between OSes, i.e. be created on some OS, and decompressed on any other (considering regular files). Is the TOC (table of contents) structure OS-dependent (i mean file attributes, maybe other things ?). I don't know what attributes are considered on win32 platforms, but i hope complex NTFS permissions are forgotten, basic unixian perms should...

  • Followup: RE: TOC for efficient embedded file location

    > Yes, there is TOC at the end of archive. OK !!! Where may one look at the TOC structure (obviously it's encoded (by which method ?), as filenames don't appear) -- in some header file i guess, does anyone know which ? I wonder if the TOC have entries like: filename ; start_offset ; end_offset ; attributes (which ones) Apart from classical entries, is there another structure...

  • TOC for efficient embedded file location ?

    hi, Do all 7zip archives have a table of contents which allows to quickly locate any embedded file (start/end offsets) ? For instance, TAR archives don't. This puts a severe penalty when one needs to pick a few files within huge archives. Fast access to file location is also a requirement to mount archives as filesystems (interesting !). So i wonder if the 7zip files have such TOCs --...
