KrzFlopt 1.23

What is KrzFlopt? KrzFlopt is rebranded KrzYoptimizer (renamed) that again is developped by me. The program is written in VB6. Why? Because I wrote my first VBS script with GUI at the age of 16 and I liked this programming language. It also is much faster than .NET platform. Also it is too simply to be rewritten to .NET, although using ConsoleRead would be nice to create some log windows/status bar information what programs KrzFlopt is using are doing in the background.



By using some advanced deflate tools like kzip, DeflOpt, 7-zip, pngout and more KrzFlopt is able to reduce file size by optimizing Deflate streams. With build in ZIP to GZ, and ExtPK to PK header and vice versa conversions the user is able to open GZ and JAR files for processing. My program directy reads data from ZIP, GZ and JAR files that I programmed basing on online documents containing information on how file headers in those files are stored. This means it doesn't require any tools to at least: Open files, convert ZIP to GZ, ExtPK to PK headers and vice versa, calculate CRC32. You can add multiple files for optimisation.

User is free to chose 3 predefined optimisation methods or define his own and select Custom Mode. For Example in Fast mode program will only try blocks from 1-16, it's good for small files. It's still recommended to create Custom mode with settings: 16 or 32 blocks to try first, search for up to 1024 blocks (kzip/pngout limit) and run at least 100 random Huffman table inits.

KrzFlopt tries to find best number of blocks to split file to by extending searching range. When it successfully found best settings and number of blocks found is equal or higher maximum blocks in this range*66% (for example 13 block is > than 16*66%) then it extends it to maximum blocks*2, till it reaches 1024.

Optimised PNG files are saved on-fly but ZIP/GZ/JAR files are stored only when it ends optimising each file in Deflate archive. Of course the program discards any data that is larger than original file.

Although program may crash from time to time (for example when opening ZIP containing MeGUI profiles - dunno why, I need to research it where the overflow occurs), it should be very stable.

Changes in this version let users send/retrieve data to/from server. This means that my server stores best results for files optimised and sends it to users to save a lot of time. For example file that is 6MB takes very long time to find best settings when searching for up to 1024 blocks. If program finds a file that its best settings data is stored on server then it jumps directly to best settings and later only random huffman table inits are run to eventually futher reduce its size a bit.

Time for some changelog on what was changed sinve fersion 1.22 till 1.23 final.

- Added additional information in TitleBar (Expert Settings)
- Added support for GnuZIP/gz (Unix) timestamp format
* File inside GZ has same time/date as file in ZIP (may reduce the time by 1h on new windowses, I need to fix it someday - it's cause by day savings)
- Added number of bytes reduced in random
tries for Randoms tab "bytesb (successes)"
- Added option to skip 7-zip 3-257 fast bytes test (only 258)
- Added End 7-zip button
- Added CRC32 calculation in File menu
- Added Strategy display: 9 /s 9 /c 9 /f 9 /d [PNG]
- Added Result sending/retrieving
* Program sends best results to server
* Program retrieves best results from server and jumps to best results
and, if selected, checks for randoms to futher reduce file length
* Works if appropriate check boxes in settings
are selected (either one or both)
* Should work fine for ZIP and PNG files.
- Fixed CRC Checking
- Fixed crash when license window was closed after being accessed
through about windows
- Fixed blocks sometimes not displaying in list. [PNG]
- Fixed: Random inits always used extreme strategy even when
it should not [PNG]
- Fixed program doing 1/2 of total maximum blocks to test for ZIP/GZ/JAR
- Fixed status not updating for PNG files
- Fixed strategy parameter not being remembered at all when PNG file
was inside Deflate file [PNG]
- Fixed compression strategy [/s] being sometimes -3 instead of 0 [PNG]
- !!Changed to new webserver: 33e.eu/www
- Skip 7-zip compression when file is in database (only KZIP-ped
files are stored anyway)
- Reduced 7-zip passes from 255 to 15 and added check for
all fast bytes settings (VERY RARERY produces file smaller
than with 258 fast bytes but DOES)
- Bugfixes for block/strategy algorithm
- now work automatically resumes when user answers NO on exit msg
- Updated CRC file on server
- Updated and fixed 'Download & Install' Module
- Code rearranging and optimisation
- Compiled without optimizations (for some reason 13KB smaller exe)
- Changed Deflate settings algorithm a bit. Now it starts checking from
block 1 and checks file size after each strategy pass (not block as before)
* May lead to better or worse results - need testing [PNG]
- Rewrote 'Limit CPU Usage' code (works better now)
- Rearranged GUI a bit
in ensuring best number of blocks mode
- Updated CRC file (pngout and jpegtran update)
- Hopefully Fixed PNG file not being repacked
* Sorry for that bug, didn't notice it earlier. Program wrongly
calculated reduced PNG size for zipslim.

KrzYoptimizer development !halted!

KrzYoptimizer development is now halted. Last release is 1.23-pre. I have lost interest in it and have other things in real live to take care of. I will probably start deving it again after some time.

Feel free to report any bugs (I may find some time to fix them).

Thank You for Your understanding.

This program is for you!

Right on time, two days after last release ;)
[download at the bottom of this post]
Today's download is sponsored by: The SoundBringers

This version improves ZIPslim algorithm and adds ability to Force Extreme strategy only for PNGslim and new improved ZIPslim algorithm. Pause functionality was improved by now ALSO pausing process it's running in background for optimisation purpouses. This allows You to reduce program's CPU usage to 0% RIGHT AFTER clicking Pause button (no need to wait for it to finish anymore). Last thing added is 'Skip Rnd' button. I planned to add it long time ago but there were more improtand things on my mind then ;P. It does skip Random Huffman Table inits for current file. You can press it anytime ZIPslim or PNGslim module is running but it will only Skip Random tries so You need to wait for it to go to that point. Very good incase you set a lot of Random Tries but didn't expect it to be THAT slow ;)

History



Known bugs:
- I noticed today that deleting from list doesn't work past last file position optimised when list was cleared and other file was loaded. I will fix it in next release. Most likely i forgot to ZERO some variable. Just restart program after optimization for now ;)

KrzYoptimizer v1.19

Version 1.19 up to download, even though I was on a party yesterday ;P

This time a lot of changes were made. I think that's something all of You want to hear. First thing to note is that there should me no more problems when program didn't look properly (has Classic windows look) on systems with enabled Windows Themes. Second is flashing window/taskbar button when some messagebox comes up and window is not focused. Third, Progressbar on taskbar button! Actually two of them that can be customized in Settings' Advanced section [Windows 7 only].

There are also minor changes/fixes:
- Speed up and fixes to update module
- Speed up, memory reduce and verbose to download module
- Speed up and file size reductions [Other]


You can download it by clicking this direct link.

You can read changelog by clicking here.

KrzYoptimizer v1.18

Version 1.18 out. Not much changes this time. There is something worth mentioning though, Update option was enabled (AT LAST!). It updates Main program with latest release available. It can run automatically or by clicking button in Options. For more info check changelog.

KrzYoptimizer v1.17

Fast update to v1.17 that fixes broken pause and few other things. I felt like releasing it the same day as v1.16 because I found a lot of things that MUST be fixed afap. For more info check changelog.


This, new version, could be called a hotfix. Said so, It also exchances few things in options to look nicer and finally to get rid of msctls.ocx. I managed to do a small workaround, because in order to do sliders/controlTabs things by api calls I would need to redirect build in VB6 Subclassing to my own custom one using WindowProc procedure and 'Case'-ing all messages. That's actually a good thing because then all Forms can be done by dynamically CreatingWindows with API calls and that may results in full WinAPI VB6 application. Of course You can't get rid of VB6.dll (or maybe there is a trick to it but I didn't really read about it) but It may help later when I will try to convert the code to C or Cpp (I'm not quite sure about doing it yet). Sometimes custom subclassic may get kind of buggy and crashy so I have it as last thing listed.

So what's in this version anyway:
- Fixed overflow on big PNGfiles [IMPORTANT!]
- Fixed infnite loops on certain ZIP files with Extra Field [IMPORTANT!]
- Reverted array back to long to fix errors in display that may have also produced incorrect results [IMPORTANT!]
- Changed/Moved controls a bit away from window edges to fix Windows Themes [MEDIUM]
- Replaced a few controls with alternatives to get rid of msctls.ocx
- and more...

KrzYoptimizer v1.15

[Update: 21:53 GMT+1]

Prerelease version of 1.16 is available for download here.
- Fixes display when Windows Theme is enabled
- Fixes infnite loops on certain ZIP files when extra field was used (filename was impreperly read)


[Original]
This version adds and improves few things. Mainly two things are worth noting:
- Faster deleting items in list
- Adding all optimizable files from directory



First one was already mentioned in post below, in prerelease version. Second allows you to open multiple ZIP/JAR/GZ files all at once and fixes limit for adding multiple Image files (The limit is 256 characters, it counted fullpath characters and all files you want to add plus one special null character to split them later), sometimes it allowed you to add only 2 files when the full path had a lot of directories and filenames were long.

KrzYoptimizer v1.15-pre #build 15

[Update 1.08.2010, 1:37AM GMT+1]

[Original]
This time more time passed ;P
I was busy with my rl work - was developing some program to help myself get some phone lines comparison (yea mainly I'm in charge of telephone lines and network connections at work. There are also computers used to sell tickets, but it's new thing that I got almost year ago.)
Anyway let's follow topic, This version mainly speed up Array reogranising when deleting items from list. What does that mean to You anyway? Let's put it simple. In older versions (1.12-) deleting items from list was quite fast, but following version 1.13 it slowed down. You may have noticed me mentioning in previous posts that 2x 2 dimensional arrays were added to prevent work corruption on Item List corruption (like that's going to happen but anyway) and speed up program a bit. You won't probably notice that it's faster bacause nowadays computers are fast enough to GET_ITEM from list almost as fast as from 2-dimensional array. Said so, It's still better to use a variable that belongs to program itself than trusting some other window (yea, listview is a window, button is also a window, every control in windows is a window).This version includes more logic into deleting items from array. Previously I was lazy to program it so it worked like this: You deleted items from list, it wiped data from corresponding array, (it checked if array number is empty and moved data one array up)x repeat number of items deleted. WOW! That's like doing uneccessary work, especially when most users select items by having SHIFT key pressed, not like everyone does CTRL or SHIFT+CTRL selection. New algorithm is based on simple selection range detector. While it deletes items from list it counts how many items were deleted consequently (You select items: 5-10, then it starts counting items from 10th to 5th) and runs function that reorganises array by moving it by number of items selected, up, for every selection range. This picture may show it better:




If You press delete now, programs will start checking all filles if they are selected (from the end of list to the beginning) as it did in previous versions. Note that there are around 15000 items but it works quite fast ;). When it goes up to 14th item it starts counting, so there goes 1 for 14th, 2 for 13th and then program notices 12th is not selected so it lunches array reorganising that moves data by 2 places up again from the end to the beginning of list, 15000=>14998 and so on. Next it continues searching for next selections. There is 11th, 10th and 9th item selected so it counts to 3 and runs array reorganising again. It may be kind of waste to run it everytime on selection range but it's still better than running it on each item, especially that You normally don't select items like on this screenshot. Better would be to (by looking at the example): detect that 14th number is last selected item (since it scans list from end to the beginning anyway) and then just move item 6 to 0, 8 to 1, 12 to 2 and detected the space between 2 and 15 and run array rearranging or something similar. In other words do some small reorganising in small area first then just move everything down by total number of selections. I'll most likely program it later ;)

That's it for this version:

KrzYoptimizer v1.14 is out to download

What this version is up to? As stated in post about v1.14-pre, I'm trying to convert a lot of things to direct WinAPI calls. That means creating windows/controls directly by calling Windows' DLL files. This saves some resources and makes program run faster because it will no longer need to read OCX (ActiveX) files that resides in memory and steal your precious system resources.

Controls that are already converted to WinAPI:
- Listview
- Statusbar
- Two progressbars

What needs to be done in order to release msctls:
- convert Options' Tabs
- convert Options' sliders

These two things mentioned will let the application unload (NOT load) msctls OCX and work a bit faster using less memory. I hope to ahieve it in next version ;)

Changelog

KrzYoptimizer v1.14-pre

Update [15:45pm GMT+1]

- VB status bar converted to msctls_statusbar32. Wow! That even decreased file a bit. Show that VB control are unoptimized...

Update [12:10pm GMT+1]:
- I added Clear list and Delete selected items file submenus (respectivelly CTRL+L and SHIFT+DEL shortcuts). First one clears list. 2nd one deletes selected files simillary to previous DEL on listview. PLEASE NOTE! This is beta stage of deleteting items in list because there is database array that needs to be erased acordingly so PROBLEMS may appear (as far as i Debugged it worked fine). PLEASE TEST IT!

Testers needed! This version has migrated Visual Basic Listview to API call (user32) SysListView32. This features column rearranging, File database multiarray (previously listview was used as a database - malicious users could corrupt data in listview then making program work incorrectly).

There is a con to it for now: you can't delete items from Listview by pressing delete button (I most likely will work it out later ;)

Download

KrzYoptimizer v1.12.2

And yeah! Another 48h passed (Not rly 48h, I think that's 36-40h ;P) and there is another version up! This time some cool Conversions were added support for Extended local headers (!!!).

What does that mean? You can now easly convert first file found in ZIP file to GZ. So if for example ZIP archive contains 10 files and they are in myprograms\ directory and files are 1.exe ... 10.exe then first file found in ZIP data (not always first one when sorted by name), in this example it can be myprograms\1.exe will be converted to GZ as 1.exe - directories are excluded because they shouldn't exist in GZ anyway.

Extended local headers are sometimes used in JAR files (maybe in ZIP too). By default ZIP programs DON'T use them to compress data, because they increase file size by number of files*16 bytes and they store CRC, file size, compressed file size that can be stored as well in File local headers. This time you can easly convert those file by picking ExtPK->PK and vice versa - if you really want your file to contain Extended local headers you can pick PK->ExtPK options.

Quick fix to prevent Settings window from unloading from memory in revision 2.

ShellandWait VB6 used in KrzYoptimizer

Shell and wait used in KrzYoptimizer looks like this (v1.11):


Private Declare Function OpenProcess Lib "Kernel32" (ByVal dwDesiredAccess As Long, ByVal bInheritHandle As Long, ByVal dwProcessID As Long) As Long
Private Declare Function GetExitCodeProcess Lib "Kernel32" (ByVal hProcess As Long, lpExitCode As Long) As Long
Private Declare Function CloseHandle Lib "Kernel32" (ByVal hObject As Long) As Long

Dim PROCESS_ID As Long
Dim ERRORLEVEL_CODE As Long
Dim TIME_STARTED As Date

Const PROCESS_QUERY_INFORMATION As Long = &H400
Const STILL_ACTIVE As Long = &H103
Const PROCESS_TERMINATE As Long = &H1

' Start the program.
On Error GoTo ShellError
PROCESS_ID = Shell(PROGRAM_NAME, WINDOW_STYLE)
On Error GoTo 0

DoEvents

' Wait for the program to finish.
' Get the process handle.
PROCESS_HANDLE = OpenProcess(PROCESS_QUERY_INFORMATION Or PROCESS_TERMINATE, 0, PROCESS_ID) ' Or PROCESS_TERMINATE
If PROCESS_HANDLE <> 0 Then
TIME_STARTED = Now

Loop While ERRORLEVEL_CODE = STILL_ACTIVE

PROCESS_ID = 0

shellAndWait = shellAndWait(PROGRAM_NAME, WINDOW_STYLE, MAX_WAIT_SECONDS, 1)
End If
Exit Function

ShellError:
stbStatus.Panels(1).text = "ERROR: " + PROGRAM_NAME + " won't run!"
End Function

Private Sub Form_QueryUnload(cancel As Integer, unloadmode As Integer)

If PROCESS_HANDLE <> 0 Then
Dim cool As Integer
Do While TerminateProcess(PROCESS_HANDLE, 0&) <> 0
cool = cool + 1
DoEvents
stbStatus.Panels(1).text = "Terminating process... " + CStr(cool)
Loop
End If
End
End Sub

Please note that it's only a part of program code.
There is still MAX_WAIT_SECONDS variable in shellandwait function. It was used to prevent program from getting stuck but it seems like those programs don't get stuck. At least as far as i tested.

This shell and wait is based on GetExitCodeProcess to check if program is still running and just incase allow program to Terminate process if user closes program when BIIIG file is being recompressed. When user interacts with GUI too much (like menu or listview scrolling) and this function is in DO_I_CHECK mode (1) - means that WE NEED error code [variable or if in other sub] - then program will be restarted as long as proper error code is returned.

KrzYoptimizer v1.10 finally out

You want to REDUCE SIZE of your PNG or JPG files to reduce traffic on your website? Maybe you just want your banners or other images to open faster on slow connections?
This program is for you!

All in one Optimizer for PNG, JPG, JAR, ZIP and GZ files.

Another version of KrzYoptimizer is out! This time a lot of changes were made that should make the program easier to use and have better functionality. Changelog:
- Totally rewritten working on files:
* Now only one file from zip is extracted at a time
* ZIP archive is optimized file per file
* Program can read compressed file size from loaded archive
- Added new icon
- Added Deflate file subitem
- Added ability to process multiple ZIP/JAR/GZ files
- Added ability to mix ZIPfiles with standalone PNG/JPG images
- Added: DELETE key on selected items in list deletes them from list
(good incase you don't want to optimize 0 byte files in zip archive - waste of time)
- Added DiffB (Difference bytes) that shows how many bytes were saved per file
- Added terminating of running Shell process to avoid errors on deleting temporary files
- Removed Save, Save As and Close menu items (they are no longer necessary because
program now bases on listview items and updates files dynamically)
- Deleted Debug Code (will be back later, was unfinished anyway)
- Changed Open ZIP/JAR/GZ file to Add ZIP/JAR/GZ file
- Changed quit message
- Code optimization (filesize greatly reduced)

So now program works mainly on Listview... Almost all data it needs to properly process files is there. In previous versions it was only to show how much of data was processed. Now it's really program's database, since it processes file by file as they would be loaded separatelly. Even every file in ZIP is done separatelly.
What does that mean? You can easly delete files you don't want to process in zipfile at runtime (as long as the file wasn't or is not being optimized) and Deflate Archive is reducing its size everytime a file inside is optimized. Program doesn't require [extraced_archive_size]b of disk space anymore. It extracts one file at a time then deletes it from temp directory when optimization ends.

As there is new feature to delete not yet processed files anytime, 'DELETE' key and multiselect functionality were added to ListView.

This version fixes bug when not all of temporary files were deleted when program was closing. This time it forces all running shell processes to terminate before getting rid of all work data.

You can now load multiple ZIP files and even mix them with JPG/PNG files being outside of archive as long as it's before You press START button.

That's all the features. Program does not yet support resuming function as ZIPslim does (even though a lot of time passed and versions were released already), but it's easy to skip already processed files (as long as You remember which one was last processed) by simply, selecting them on list and then pressing 'DELETE' key (maybe I will add some logfile in next version to help You to find out which file it stopped processing at).

This version has been up for 2 days but I didn't have enough time to post it here (sorry busy with rl)... Anyway version 1.09 changelog:

- Fixed, blocked Listview editing that could corrupt results
- Added forcing of first block search range (some files don't want to reduce size at
1-16)
- Added some additional checks to loading config file
- Changed Open PNG/JPG files... to Add PNG/JPG files that dynamically adds new files
to already populated list view...
- Clearing list question when adding files to a list that contains already optimized files




STARTING FROM VERSION 1.10 ZIP OPTYMIZATION ALGORITHM IS REWRITTEN A BIT, benefits:
- required space to run optimization reduced from [extracted_archive_size] to [extracted_file_to_optimize_size]
- archive is updated everytime file in list optimization is done
- 'd' key on selected item in list can easly remove file (incase some of them are already optimized and you don't want to waste time on them)
- smaller exe (less code)
- more

All programs can be found here

This time it took a while... whew... Not really that much of work needed to be done to take this much of time, but I got somewhat busy with real life (no time to work on it at work - other project at work was priority, even though nobody asked me to do, I did it for myself for easier telephon numbers listing). There were also other projects running there like String2chr or NEW (not yet up) String to 6BH, this one is still in beta stage and works only on text-boxes, not real files although it would be capable to (not yet converting backwards but I already worked out all mathematic here).

Now let's get back to the thing I should be writing about.



What's in this version? Check the pricture, you can notice new List view that looks muuuuuuch nicer than old one. Anyway, list of changes:

- Changed how zipslim works:
* 7-zip now recompresses all files in normal method
* each file is now recompressed with 7-zip (mfb=258, pass=32) before K-zip
- Added ListView Box instead of plain ListBox:
* File - file path+name
* Size - uncompressed or unoptimized/original file size (incase of JPG/PNGslim)
* Compressed - compressed or optimized file size
* Ratio - Compression Ratio (compressed size/original size * 100%)
* S - State: D, P (D - Done, P - Processing
- Added ability to download/update program's CRC file
- Added CRC textboxes and CRC button - click to check if program CRC matches
- Added resize ability
- change to Total progress:
* don't update progress and label when restarting Random Huffman, just fix it to old value
(less computations and not going ahead of operation progress)
- Code organising

All programs can be found here

String2chr and KrzYopti v1.06

I released new tool. It's called String2chr, it converts any text in textbox into chr(number)+chr(number)+<...>+chr(number)... If you write Visual Basic Scripts or program in Visual Basic you may find this tool useful... It's sometimes good to hide text inside vbscript or EXE. YES, You are right, string made by chr()'s is not visible if somebody views your VBscript or EXE! Took me 30 min to script, it allows You to resize or even maximize window by resizing all contols at the same time!

All programs available on http://freya.neostrada.pl


Also KrzYopti v1.06 is out:
v1.06 5-June-2010

about that - too much code =D)
- Added more tooltips
- Code organising

v1.05 rev2 4-June-2010
- Quick fix for jar files (crash on Save)
- Fix for PAUSING (didn't work due to Assume no Aliasing turned on)

v1.05 4-June-2010
- Changed how program checks if file exists - fixes bug when path started with disk drive letter
[again proves that VB6 is stupid]
- Added debug mode (not fully complete yet but working ;)
- Fixed not working pause button
- Fixed bug when PNG is unsupported format - didn't delete backup file
- Added ability to pause work in PNGslim
- Added option to use PNGslim while optimizing zip
- Added Program Executables for PNGslim (and included in Download & Install module)
