Neuß | Hi,
has Perhaps already time quellcodemäßig with the pack of data/Files engage? with the Search in the network stößt one over ands over again on the Huffman-tree to Datenkomprimierung. in the Grunde understand I, what To do is, but Perhaps has Yes someone already something in the direction program.
is sure not kriegsentscheidend and the Topic get one with Freeware (z.B. 7z) or here erhältliche Units and DLLs too well resolved.
I likes it hold, if I possible everything in EINE EXE pack can and then self bestimme, what the program power.
OK. not long drüber cogitate, but if someone what white...
THANK YOU  |

 | salvo!
I had time with Profan² 4.5 (or wars 7?) myFile2Source ( [...]  ) program -
imho the first in Profan programmed Program circa Files directly in Profan-Source to take off.
there I had a (Own) "Kompressionsroutine" installed also correctly. slow was what about me having sometimes so stronger as zipper compressed but it lasts even forever. ^^
so remaining well always the Auswiegen the Verhältnisses between Rechenzeit/ Komressionsrate.
example of/ one Variante:
Zeichenkette: AAAA
compressed: R1A4
R=Repeat
1=CharCount
A=CharCount
4=Wie often
=
1A*4
=
AAAA
so can itself a or even meherer Kompressionsmethoden consider and these against too yet übereinander/ gegeneinander set and then against The Kompressionswerte by scheduler vergleichen around the optimale Variante anzusetzen.
Obiges AAAA-example called well too RunLength-Variante or. RLE.
likewise can naturally on complex replays testing -
beispielswiese
ABCDEROFLABCDE could
u5ABCDEROFLu-4 his where then each further ABCDE-Repeat just u-4 would. |

|
 | | here one Source, the with API operates: [...] |
|
| |
| |
| |
|
|
| unfortunately pack the Source nothing separate ("nur") The APIs -
but vlt. was too The question. |

Neuß | | i'd the pack and ggfs. The Verschlüsselung already gladly yourself make. means not over The API. |
|
| |
| |
| |
|
|
| | from welchem reason very? |
|
| |
| |
| |
|
|
| | vlt. höhere Kompressionsrate allows through specialization. |
|
| |
| |
| |
|
|
| The API's can with several Kompressionsarten pack: LZ, Xpress and Xpress Huffman. I bezweifle heavy, that one with reinem XProfan meaningfully effective pack can. This will then plenty too slow.
If one itself with the API only slightly keep busy would or generally itself so time make friends tried, could to the capability very quick discern. must but eachone yourself know.  |
|
| |
| |
| |
|
|
| I know already How one with XProfan meaningfully effective pack can -
you are Yes sure too the opinion the one spezialisiertes take action höhere Packraten produce can.
so can in example with XProfan a Packer write the z.B. XProfan-View source "besser" pack as LZ & co.
for More speed can Yes eachone ASM and nProcs bring into action. |
