VB PhotoShop clone. Various image effects - rotation, flip, fade, color manipulation, fish-eye,swirle etc plus various filters - soften/sharpen/custom etc. A lot of undocumented staff including using MSOffice graphic convertion filters, pure VB calling dll functions by its pointers, assembly language inside VB and much more!

Hello guys!
Thanks for voting! Some notes:
1. Running in IDE this code is extremelly slow, but when compiled with Fast optimization and checking all advanced tabs it's almost as fast as commercial/C samples.
2. Code was tested on w98/IE5.0/MSOffice_97. Since I used a lot of undocumented staff, some functionality may be lost on other versions, especially 2000/XP. It was reported that MS Office Export filters doesn't work on w2000/MSOffice2000 - seems sEatStackSpace trick doesn't work. Now I'm working on fixing this prb.
Regards
Ark

I gave you a 5, probably more so for the very useful tid bits that you didn't mention. Your tweaks on the Common Dialogs were exceptional and I wish I were the one that figured how to use the shared graphic file filters. For me this was probably one of the more useful pieces of code I have got off of here. Who cares about the bugs here and there. Good Work and Thanks!

FYI, there are many more filters available in XP, that your code picks up. Importing works well, but haven't had much luck with exporting. When I play with it more I'll give you better info. I did find you can copy some of filters from XP to Me, make the mods to the registry and what I have tried works fine.

Hello sblosser
Thank you for interesting this code. I'll be glad give you all credits if you'll find a way to use Export filters in 2000/XP. Unfortunatelly, this staff is totally undocumented - I couldn't find anything over the NET. Most recent doc about Import filters dated by April 1992(!) - you can find it in Dr. Dobbs archive. Though all declarations there are 16 bit, I could replace them with 32bit equivalents and found almost all staff by experiments.
As for Common dialog extencion - I simply forgot to mentioned it :) Let say, this is 'much more' :)
For those who interesting - there is a trick in this sample showing how to subclass common dialog and use additional VB Form as template to extend ComDlg functionality (preview, additional controls etc).
Thanks and regards

hi there!
ark, look here for clsASMpic 1.0, realtime image processing of even large pictures in VB using inline assembly:

...also watch out for code by robert rayment, really fantastic stuff!
gx, buggy

Hello buggy!
Your class is really nice and gave it 5 globes. But my goal was a bit different - I want to show pure VB image processing (though I tried make it as fast as possible) with easy to understand algorithms. I also use inline assembly, not for speed but for "impossible" (as MS claimed) task - calling function by pointer.
BTW, I have a "clone" of my CallApiByPointer/Name - CallApiFromArray which any dll as byte array and allow call any function by it's offset. If you're interesting, you may contact me at ark@msun.ru
Regards
Ark
PS. Many thanks to all who voted me!

Arkadiy, i was about to report that this code is "borrowed" from RealVBCode but then YOU are the original author :-)) Nice one! Especially the work on the Aldus imp/exp filters! Btw, do you think Page Maker filters will work with your framework?

Hello Vlad. Thanks for responce and voting. I think you mean "FreeVBCode", not "RealVBCode" (though I won't suprise if you found my samples anywhere else - they spread over the NET withou my permission :)). I've posted it twice to allow more ppl learn low-level image processing with VB.
As for Page Maker filters - here is a list of filters I've tested:
'MS Office (all works fine)
BMPImp32,CDRImp32(Corel Draw version ~6 or so), CGMImp32, DRWImp32,DXFImp32, EMFImp32, EPSImp32, FPX32, GIFImp32, HPGLIm32, JPEGIm32, PCDImp32, PCXImp32, PICTIm32, PNG32, TGAImp32, TIFFIm32, WMFImp32, WPGImp32
'Paint Shop Pro (all works fine)
CDR32, CMX32, DRW32, DXF32, GEM32, HPGL32, WPG32
'Corel Draw (v.9)
'All seems don't work correctly
Assuming all above, seems this technique shouldv work with PM versions 2-5.

Great work, Ark. The MSOffice interfacing is very clever and well-written. Hats off too, for doing it without any good documentation to refer to :) Those MSN articles can be pretty messy...

Good tool.
but dont save images!!
Because??

Hello All!
Thanks for supporting!
Michele, probably it doesn't save images because of using MSOffice filters for saving. Just switch off those filters and save as bmp.

Nice work, 5 globes. One error: nMax is allowed to exceed the ProgressBar's Max value. Easy to fix, but something's wrong in the class that raises the event.

Good job! I'm currently making image processing functions in C++. I've also been thinking of changing it to VB. Your code shows me you can have efficient code in VB. Thanks!

"It was reported that MS Office Export filters doesn't work on w2000/MSOffice2000 - seems sEatStackSpace trick doesn't
work. Now I'm working on fixing this
prb."
I'm waiting for it... :)
In the meantime, 5 globes are mandatory!

Nice code... but could you try to post a project which focuses mainly on BMP to JPEG conversion? I'm sure it'll be a hit, considering your code's small size... :D

Great code but would you consider adding an option to centre the image in the window, also a shrink image to fit window would be a nice.

I havn't downloaded the code yet, however will do shortly as I am doing the manipulation of digital images as a final year project at uni. Ark, do you think you could give me further explanation of code if required? Also, as part of my project do you think I could perhaps evaluate your product compared to commercial products such as photoshop?
Regards.
